Description

  The present invention relates to information necessary for operation of an application program, and more particularly to an information providing system, an information generating method, a server, and an information providing program capable of efficiently storing and acquiring information.

  Conventionally, in an information providing system, since many application programs operating on a computer system require information in which the operation characteristics and execution environment of each application program are set in the operation, a format required by each application program in advance This information is described in the file of the storage device and is provided when the application program is executed.

  This file is prepared separately for each application program, each user, each computer device, etc., depending on the application program to be executed and the execution environment when the application program is executed. Further, this file is distributed and arranged in a unique area corresponding to each application program and each execution environment in the area for storing the file.

  An example of such a conventional information providing system is described in Patent Document 1.

The information extraction device described in Patent Literature 1 is a device that retrieves information requested by a user by searching a specified electronic document and provides the information to the user.
JP 2004-303160 A

  However, the conventional information acquisition method described above has the following problems.

  First, for information that is common in different execution environments (information with the same setting value), the application program must be able to acquire regardless of the effective environment. For this reason, common information must be described in each file for each execution environment. Therefore, since it is necessary to create a plurality of files in spite of common information, it is a problem that a large storage capacity is required.

  Second, if the application program acquires information common to the application program (such as default setting information) and information required for each execution environment from different files, the programmer who creates the application program It is a problem that it takes a burden.

  The reason for this is that when an application program refers to a file for information acquisition, it considers the file that stores common information and the file that stores information required for each execution environment. This is because, in the process of creating the application program, the programmer is required to incorporate in advance a process based on unique correspondence with respect to the file reference process.

  The third problem is that it is difficult for a computer system administrator to grasp the storage area of each file.

  This is because a large number of files are generated for each application program and its execution environment as the computer system is operated. Furthermore, in the file storage area, since the policy for storing the file is different for each storage area, each file is distributed and arranged in each area in the file storage area.

  Fourth, in the apparatus described in Patent Document 1, even when there is no information requested by the user in the electronic document to be searched, the information requested by the user may not exist unless all information of the electronic document is searched. Because it does not know, it takes time to search for information in a new electronic document, so it takes time to search for information requested by the user, and the processing for acquiring that information is burdensome. It is a problem that it takes.

  The reason is that the attribute of the information requested by the user cannot be identified, and it is necessary to search at random.

Are extracted in order from the beginning of the character string constituting the environment name 6.

  Note that the environment setting information generation control unit 131 sequentially extracts the node names of the namespace directory 154 from the upper nodes by sequentially calling the environment name decomposition unit 132, so that the search path of the namespace directory 154 can be obtained. .

  The name space moving unit 133 has a function of moving a search node, which is included in the name space directory 154 (described later) and is a search target, to a lower node acquired by the environment name decomposing unit 132.

  The environment setting table construction unit 134 includes an XML parser 1341 and a setting item combination unit 1342.

  The environment setting table construction unit 134 constructs the environment setting table 142 by using parameters constituting the environment setting information indicated by the environment setting file read by the file reading unit 153 (described later).

  The environment setting table construction unit 134 uses an XML parser 1341 and a setting item combination unit 1342 in a series of processes for constructing the environment setting table 142.

  The XML parser 1341 is a software component that is widely distributed to interpret XML documents, and has a DOM (Document Object Model, which will be described later) interface that is common in the XML parser 1341, and allows elements to be selected using an XPath expression. Use something. In other words, the XML parser 1341 is a tool that enables various application programs to handle documents described using XML technology in application programs.

  In the present embodiment, the XML parser 1341 creates a DOM tree 141 by converting data of an environment setting file described in XML for each node.

  Note that XPath is a well-known standard that defines a description method for indicating a specific element of the content of an XML document expressed in a tree structure, and a description thereof will be omitted.

  Based on the control of the environment setting table construction unit 134, the setting item combining unit 1342 is obtained from the environment setting file read by the file reading unit 153, and the environment setting information that is the component of the DOM tree 141 by the XML parser 1341. It has a function of taking out setting items and setting values (information indicating them) from the parameters and adding them to the rows of the environment setting table 142 (described later).

  Note that the setting item combining unit 1342 gives priority to the contents of the components of the DOM tree 141 created from the environment setting file of the node arranged below the name space directory 154, and sets the environment setting information by the union of parameters. Generate. Therefore, if a line having a setting item to be added to the environment setting table 142 already exists in the environment setting table 142, the setting value is overwritten.

  The shaping transmission unit 135 has a function of converting all lines existing in the environment setting table 142 acquired from the environment setting table 142 into an XML format, and transmitting the converted data to the environment setting information generation control unit 131.

(File system configuration)
FIG. 2 is a block diagram showing a configuration of a part of the environment setting information providing system according to the first embodiment of the present invention.

  Referring to FIG. 2, the environment setting information providing system 100 according to this embodiment includes a file system 15 on the server 1.

  The file system 15 includes a lower directory obtaining unit 151, a directory moving unit 152, a file reading unit 153, and a name space directory 154.

  The file system 15 is capable of hierarchical file management by directory, has a concept of a current directory indicating a working directory, and constructs a namespace directory 154 (described later) having a tree structure.

  That is, the file system 15 searches the namespace directory 154 according to the path information indicated by the character string of the environment name 6 for the environment setting file associated with each node and held hierarchically by the tree structure. This is a system for acquiring parameters of environment setting information included in the corresponding environment setting file.

  In the file system 15, the environment setting file associated with the higher level node is more general, and the environment setting file associated with the lower level node describes more detailed settings.

  Note that the file system 15 is a generally popular file system, and the server 1 implements the name space directory 154 using the file system 15.

  The lower directory acquisition unit 151 has a function of acquiring a directory list directly under the current directory indicating a working directory.

  That is, the lower directory acquisition unit 151 determines whether or not there is a lower node held under the currently searched search node (current directory), and if there is a lower node, the contents of the lower node are included. The subordinate directory is acquired, and the name of this directory is transmitted to the name space moving means 133.

  The directory moving unit 152 has a function of moving the current directory to an arbitrary node of an arbitrary directory based on the directory name transmitted from the namespace moving unit 133. For example, the current directory is moved to the namespace directory 154. To the directory (starting directory) that becomes the root node 2000 of the current node.

  The directory moving unit 152 also searches the current node name when the node name (directory name) to be searched next acquired by the environment name decomposing unit 132 is present in the lower node by the lower directory acquiring unit 151. The searched search node (current directory) is moved to the lower node acquired by the lower directory acquisition means 151 and set as a search node to be newly searched.

  The file reading unit 153 has a function of reading the contents of an arbitrary file on a search node (current directory) in a namespace directory 154 (described later) and transmitting it to the environment setting table construction unit 134.

  FIG. 3 is a tree diagram showing the structure of the namespace directory provided in the file system 1 according to the present embodiment.

  Referring to FIG. 3, the name space directory 154 according to the present embodiment has a tree structure with the root node 2000 as a vertex, and is expressed using a directory of the file system 15.

  The root node 2000 can hold a plurality of nodes such as nodes 2100 and 2200 in the lower order.

  Nodes immediately below the root node 2000, such as the nodes 2100 and 2200, are referred to as the highest level node of the namespace directory 154.

  Nodes other than the root node 2000 always have one upper node, and can hold a plurality of lower nodes and one environment setting file. That is, nodes other than the root node 2000 do not need to hold the environment setting file. In addition, an environment setting file that does not include substantial contents may be held. Regardless of whether the actual contents are included or not, if all nodes hold environment setting files, all nodes on the path of the namespace directory 154 must always hold the environment setting files. Therefore, the character string constituting the environment name 6 and the environment setting file have a one-to-one correspondence and are easily categorized.

  For example, the node 2100 holds the environment setting file 2100A, and the nodes 2110 and 2120 held lower by the node 2100 hold the environment setting files 2110A and 2120A, respectively.

  Similarly, the node 2200 holds the environment setting file 2200A, the nodes 2210 and 2220 held in the lower level by the node 2200 hold the environment setting files 2210A and 2220A, respectively, and the node 2211 held in the lower level by the node 2210. , 2212, and 2213 hold environment setting files 2211A, 2212A, and 2213A, respectively.

  Note that the environment setting files 2100A, 2110A, 2120A, 2200A, 2210A, 2220A, 2211A, 2212A, and 2213A according to the present embodiment are common to the environment setting file name 1433 “config.xml”.

  The contents of each node constituting the namespace directory 154 are each directory of the file system 15.

  Among these, the content of the root node 2000 is equal to the directory of the file system 15 indicated by the origin directory name 1432.

  The node names of nodes other than the root node 2000 are the same as the directory names of the file system 15.

  The namespace directory 154 has a concept of a search node.

  The search node is a node to be read when searching the namespace directory 154 and reading the environment setting file. Then, the namespace directory 154 is searched in order from the highest node to the lower node based on this search node.

  The search node is equal to the current directory of the file system 15.

  The contents of the environment setting file that can be held by each node are the contents of the file in the corresponding directory of the file system 15 that is the contents of each node, and the environment setting file name 1433 that is the file name of the environment setting file (described later). ) Is equal to the file name of the file in the corresponding directory.

  That is, the file having the file name specified by the environment setting file name 1433 is recognized as the environment setting file.

  In addition, the namespace directory 154 apparently inherits the attributes of the environment setting file arranged on the upper side of the predetermined route by the environment setting file arranged on the lower side of the predetermined route.

  Note that even if a file having a file name other than that specified by the environment setting file name 1433 exists in the directory that is the contents of the node of the namespace directory 154, the server 1 ignores this, so there is no problem.

(Configuration of storage unit)
The storage unit 14 has a function of storing information by updating it, and includes a DOM tree 141, an environment setting table 142, and a parameter extraction element 143 as shown in FIG.

  FIG. 4 is a tree diagram showing the configuration of the DOM tree in the storage unit of the environment setting information providing system according to the present embodiment.

  Referring to FIG. 4, the DOM tree 141 according to this embodiment is such that the XML parser 1341 extracts the contents of the environment setting file described using the XML technology for each node on the path of the namespace directory 154. It is constituted by data generated by conversion.

  That is, the DOM tree 141 according to the present embodiment is created for each node on the path of the namespace directory 154.

  It is a well-known fact that an XML document can be expressed in a tree structure.

  The DOM tree 141 has an XML node “<add key =“ COLOR ”value =“ WHITE ”>”, for example.

  FIG. 5 is a diagram showing an environment setting table in the storage unit of the environment setting information providing system according to the present embodiment.

  Referring to FIG. 4, the environment setting table 142 according to the present embodiment is composed of tabular data constructed by the environment setting table construction unit 134, and a plurality of environments sequentially added by the environment setting table construction unit 134. The parameters of each environment setting information in the setting file are accumulated as a union.

  The environment setting table 142 is composed of zero or more “lines”, and this “line” indicates a set of setting items and setting values extracted from the environment setting information.

  FIG. 6 is a block diagram showing the configuration of parameter extraction elements in the storage unit of the environment setting information providing system according to the present embodiment.

Referring to FIG. 6, the parameter extraction element 143 according to the present embodiment stores elements such as a character string used for extracting the parameters of the environment setting information to be generated. An environment name storage area 1431 including a directory name 1432, an environment setting file name 1433, an environment setting element name 1434, a setting item attribute name 1435, and a setting value attribute name 1436 has been queried from the client 4. This is a storage area for storing the environment name 6 while the server 1 is processing the response.

  Note that the stored character string constituting the environment name 6 becomes shorter each time the node names included in the character string constituting the environment name 6 are sequentially extracted by the environment name decomposing means 132, and the response process for the environment name 6 is performed. It will be 0 characters when is finished.

  The origin directory name 1432 indicates the root node 2000 that is a component of the namespace directory 154. Note that the contents of the directory of the file system 15 indicated by the starting directory name 1432 are the same as the contents of the root node 2000.

  The environment setting file name 1433 can be held by each node, and includes a plurality of parameters constituting the environment setting information. XML (extensible) is a kind of markup language for describing the meaning and structure of documents and data. Indicates the file name of the environment setting file described in Markup Language).

  The environment setting element name 1434 is a character string indicating an index of an XML node existing at an arbitrary position in the environment setting file.

  The setting item attribute name 1435 is a character for extracting a setting item necessary for the operation of the application program 441 from the description of the XML node indicated by the environment setting element name 1434 as a parameter which is a component of the environment setting information 7. Indicates a column.

  The setting value attribute name 1436 is a character for extracting a setting value necessary for the operation of the application program 441 from the description of the XML node indicated by the environment setting element name 1434 as a parameter which is a component of the environment setting information 7. Indicates a column.

(Client behavior)
The operation of the client will be described with reference to FIG.

  FIG. 7 is a flowchart showing the operation of the client 4.

  First, the environment name 6 for acquiring the environment setting information 7 to be processed by the application program 441 is set (step A1).

  For example, the environment name 6 when the user “user1” uses the application program “ap1” is set to “ap1.user1”.

  Of course, naming conventions for environment names such as “ap1” and “user1” are decided on the client 1 side and the server 4 side.

  Further, the administrator of the server 1 constructs a name space directory 154 (see FIG. 3) corresponding to the environment name 6 in the file system 15 in advance, and prepares an environment setting file for each node.

  For example, when the starting directory name 1432 is “/ configs”, directories with directory names “/ configs / ap1” and “/ configs / ap1 / user1” are created in the file system 15.

  That is, the contents of the file in the corresponding directory indicated by the name “/ configs / ap1” of the directory that is the highest node are arranged as the contents of the environment setting file that is common to the application program “ap1”.

  Further, when the application program “ap1” is used by the user “user1”, it is the contents of the node below the highest node, and the directory name “/ configs / ap1 / user1” below the directory name “/ configs / ap1”. The contents of the file in the corresponding directory, which is the contents of, are arranged as the contents of the environment setting file dedicated to “user1”.

  The environment name 6 set in step A1 is input, and the environment setting information inquiry means 431 is called (step A2).

  The environment setting information inquiry unit 431 transmits the input environment name 6 to the server 1 via the transmission unit 41 (step A3).

  The environment setting information inquiry unit 431 waits for reception of the environment setting information 7 from the server 1 via the receiving unit 42 (step A4).

  The environment setting information inquiry means 431 receives from the server 1 the environment setting information 7 sent as a response to the environment name 6 transmitted to the server 1, and when this reception is completed, the environment setting information inquiry means 431 uses the environment setting information 7 acquired by reception as the application. The program is transferred to the program 441 (Step A5).

  The application program 441 appropriately interprets the environment setting information 7 delivered from the environment setting information inquiry means 431, and determines the operating characteristics of the application program 441 itself (step A6).

The client 1 realizes the operation by the application program 441 whose operation characteristics have been determined by the above procedure.
(Server operation)
An outline of the operation of the server 1 will be described.

  The server 1 receives the environment name 6 from the client 4, searches the namespace directory 154 based on the path information included in the environment name 6, accumulates a plurality of information obtained in the search process as a union, The ring setting information 7 corresponding to the environment name 6 is generated and transmitted to the client 4.

  8 to 13 are block diagrams showing the operation of each constituent means of the control unit provided in the server of the environment setting information providing system according to this embodiment.

  Hereinafter, the operation of each means constituting the server 1 will be described in detail with reference to the drawings.

(Operation of ring setting information generation control means)
FIG. 8 is a flowchart showing the operation of the ring setting information generation control means of the control unit provided in the server.

  With reference to FIG. 8, the operation of the ring setting information generation control unit 131 provided in the control unit 13 will be described.

  The environment setting information generation control unit 131 is in a standby state for received data, and receives the environment name 6 transmitted from the client 4 via the receiving unit 11 (step B1).

  When the environment setting information generation control unit 131 receives the environment name 6, the environment setting information generation control unit 131 sets the current directory as the root node of the name space directory 154 of the file system 15 (see FIG. 2) via the directory moving unit 152 of the name space moving unit 133. (Step B2).

  For example, if the starting directory name 332 is “/ configs”, the current directory is moved to the directory indicated by the directory name “/ configs” in step B2.

  The environment name 6 inquired from the client 4 is stored in the environment name storage area 1431 of the parameter extraction element 143 (step B3).

  For example, if the queried environment name 6 is “ap1.user1”, in step B3, the saved content of the environment name saving area 1431 is “ap1.user1”.

  A start node is transmitted to the client 4 via the transmission means 12 (step B4).

  The start node is an XML format node that represents the beginning of the environment setting information 7.

  The node name of the start node is preferably a name that can be easily imagined that the node to be transmitted thereafter is the environment setting information 7. In this embodiment, “<CONFIG>” is used.

  Next, the node name (directory name) of the namespace directory 154 to be searched next is acquired from the environment name 6 stored in the environment name storage area 1431 using the environment name decomposing means 132 (step B5).

  For example, if the environment name “ap1.user1” is stored in the environment name storage area 1431, it is composed of a character string up to the first “. (Period)” in the first call of the environment name decomposing means 132. The node name “ap1” is acquired, the node name “user1” is acquired by the second call, and the null character (0 character) is acquired by the third call.

  In step B5, it is determined whether or not the character string constituting the node name acquired from the environment name 6 by the environment name decomposing means 132 is one character or more, that is, whether or not there is a node to be searched (step B6). .

  If it is determined in step B6 that there is still a node to be searched, the lower directory acquisition unit 151 acquires the node to be searched (lower node), and the directory moving unit 152 sets the search node to the lower node (step B5). (Step B7).

  Next, the success or failure of the search node movement by the directory moving means 152 is determined (step B8).

  When the search node is successfully moved in step B8, the environment setting file held by the moved search node is read using the environment setting table construction unit 134, and the parameters of the environment setting information existing in the environment setting file are set in the environment setting table. By adding to 142, the environment setting table 142 is constructed (step B9).

  After the environment setting table 142 is constructed in step B9, the process returns to step B5, and the procedure for moving the search node and reading the environment setting file is repeated.

  If it is determined in step B6 that the node name obtained in step B5 is an empty character, it is determined that the search for the environment name 6 has been completed up to the target node, and the search for the namespace directory 154 is terminated (step B10).

  When the search is finished in step B10, the ring setting information generation control unit 131 uses the shaping transmission unit 135 to convert the environment setting table 142 into the XML format and obtain it as environment setting information (step B11).

  Note that the search is ended also when the movement of the search node becomes an error in step B8, and the environment setting information is acquired using the shaping transmission means 135 (step B12).

  Since the environment setting information transmitted in step B12 is incomplete environment setting information that has not searched all the nodes indicated by the environment name 6, the ring setting information generation control unit 131 receives the environment setting information, An error node in the XML format is transmitted to the client 4 via the transmission unit 12 (step B13).

  The error node means that an error has occurred in the generation of environment setting information.

  The node name of the error node is preferably a name that makes it easy to imagine the occurrence of an error. In this embodiment, “<ERROR />” is used.

  If an error may occur due to another cause, an attribute indicating the cause of the error may be provided in the error node (for example, <ERROR kind = “xml parser error” />).

  Through the procedure as described above, the environment setting information generation control unit 131 finally transmits a stop node to the client 4 via the transmission unit 12 regardless of whether an error has occurred during generation of environment setting information (step B14). ), The transmission of the environment setting information 7 is completed.

The stop node is a node that represents the end of the environment setting information, and must be a node that closes the start node in the XML syntax. In the present embodiment, “</ CONFIG>” is assumed.
Then, the environment setting information generation control unit 131 returns to step B1 after the end of step B14, and enters a standby state for received data.
Note that the environment setting information generation control unit 131 also repeats predetermined processing as appropriate in each step and moves the processing to the next step.

(Operation of environment name resolution means)
FIG. 9 is a flowchart showing the operation of the environment name decomposing means of the control unit provided in the server.

  With reference to FIG. 9, the operation of the environment name decomposing means 132 provided in the control unit 13 will be described.

  The environment name decomposing means 132 creates a variable “DIR” that can store a temporary character string (step C1).

  The environment name 6 in the environment name storage area 1431 is referred to (step C2), and the presence / absence of “. (Period)” in the environment name 6 is determined (step C3).

  The case where the environment name 6 includes “. (Period)” is, for example, the case where the environment name 6 is “ap1.user1”, “editor.test.admin”, or the like.

  The case where the environment name 6 does not include “. (Period)” is, for example, the case where the environment name 6 is “user1” or an empty character (0 characters).

  If it is determined in step C3 that the environment name 6 stored in the environment name storage area 1431 includes a period, the first “. ( The character string immediately before “period” is stored in “DIR” (step C4), and the character string from the beginning of the character string of environment name 6 stored in the environment name storage area 1431 to the first period is deleted (step C4). Step C5).

  For example, if the environment name 6 in the environment name storage area 1431 is “ap1.user1”, “DIR” is “ap1” and the environment name storage area 1431 is “user1” in step C7.

  If it is determined in step C3 that the environment name 6 stored in the environment name storage area 1431 does not include a period, all character strings in the environment name storage area 1431 are stored in “DIR” (step C6). All the character strings in the storage area 1431 are deleted (step C7).

  For example, when the environment name 6 in the environment name storage area 1431 is “user1”, “DIR” is “user1”, and the environment name storage area 1431 is a null character.

  The environment name decomposing unit 132 provides the environment setting information generation control unit 131 that is the caller of the environment name decomposing unit 132 with the character string stored in “DIR” in step C4 or C6, which becomes the next search node name. (Step C8).

(Operation of namespace movement means)
FIG. 10 is a flowchart showing the operation of the name space moving means of the control unit provided in the server.

  With reference to FIG. 10, the operation of the namespace movement means 133 provided in the control unit 13 will be described.

  First, the name space moving unit 133 is equal to the search node name extracted by the environment name decomposing unit 132 from the destination directory name (the environment name 6 stored in the environment name storage area 1431) by the environment setting information generation control unit 131. ) Is provided and called.

  The name space moving unit 133 acquires a list of directories (lower directories) immediately below the current directory by the lower directory acquiring unit 151 (step D1).

  Next, it is determined whether or not the migration destination directory provided from the environment setting information generation control means 131 exists in the lower directory list acquired in step D1 (step D2).

  When it is determined in step D2 that the destination directory exists, the directory moving unit 152 changes the current directory that is the content of the search node to be searched to the destination directory that is the content of the next search node to be searched. It moves (step D3) and transmits movement success information indicating that the movement is successful to the setting information generation control means 131 that is the caller (step D4).

  If it is determined in step D2 that the destination directory does not exist, error information indicating that the migration has failed (error) is transmitted to the setting information generation control unit 131 that is the caller (step D5).

  For example, when the provided destination directory name is “ap1”, the directory name of the current directory is “/ configs”, and the directory name “/ configs / ap1” exists in the file system 15 (see FIG. 2). In step D2, it is determined that the destination directory exists, and the current directory is moved to the directory indicated by the directory name “/ configs / ap1”.

  If “/ configs / ap1” does not exist in the file system 15, an error is assumed.

(Operation of the environment setting table construction means)
FIG. 11 is a flowchart showing the operation of the environment setting table construction means of the control unit provided in the server.

  The operation of the environment setting table construction unit 134 provided in the control unit 13 will be described with reference to FIG.

  The environment setting table construction unit 134 reads the environment setting file (see FIG. 2) held in the current directory (search node) by the file reading unit 153 (step E1).

  For example, when the directory name of the current directory is “/ configs / ap1” and the environment setting file name 1433 is “config.xml”, the contents of “/config/ap1/config.xml” are read as the environment setting file.

  The success or failure of reading the environment setting file in step E1 is confirmed (step E2). If reading of the environment setting file fails (no file exists), the process ends without doing anything.

  If the environment setting file has been successfully read, the DOM tree 141 (see FIG. 4) of the environment setting file is stored in the storage unit 14 based on the data generated by the XML parser 1341 converting the content of the read environment setting file into a tree structure. ) Is constructed (step E3).

  An XML node that holds the element name indicated by the environment setting element name 1434, the attribute name indicated by the setting item attribute name 1435, and the attribute name indicated by the setting value attribute name 1436 from the DOM tree 141 constructed in step E3. Is generated (step E4).

  For example, if the element name indicated by the environment setting element name 1434 is “add”, the attribute name indicated by the setting item attribute name 1435 is “key”, and the attribute name indicated by the setting value attribute name 1436 is “value”, step E4 The XPath expression generated in is “// add [@key] [@ value]”.

  By inputting the XPath expression generated in step E4 to the XML parser 1341, the XML node including the parameters of the environment setting information is extracted from the DOM tree 141, and the first one node is selected from the extracted XML nodes ( Step E5).

  It is determined whether or not the selected XML node exists (step E6). If the selected XML node exists, the XML parser 1341 is used to set the setting item and the setting value (information indicating the selected XML node). Is acquired (step E7).

  For example, “HIGHT” as a setting item and “100” as a setting value are acquired from an XML node “<add key =“ HIGH ”value =“ 100 ”>”.

  Using the setting item combining unit 1342, the set of setting items and setting values acquired in step E 7 is added to the environment setting table 142 (see FIG. 5) (step E 8). The detailed operation of the setting item combining unit 1342 will be described later.

  Among the XML nodes extracted in step E5, the XML node to be processed next to the XML node processed in steps E5 to E8 is selected (step E9), and the process returns to step E6.

  When all the XML nodes extracted in step E5 are processed, there is no XML node that can be selected, so the DOM tree 141 is deleted (step E10), and the construction of the environment setting table 142 is terminated.

  The environment setting table construction unit 134 constructs the environment setting table 142 by the procedure as described above.

After that, the environment setting table construction unit 134 is called again from the environment setting information generation control unit 131 if there remains a search node to be read when the environment setting file is read.
(Operation of setting item combination means)
FIG. 12 is a flowchart showing the operation of the setting item combining means of the control unit provided in the server.

  With reference to FIG. 12, the operation of the setting item combining unit 1342 included in the control unit 13 will be described.

  First, the setting item combination unit 1342 is called by the setting item and setting value (information indicating) provided by the environment setting table construction unit 134.

  The setting item combining unit 1342 searches whether a line having the same setting item as the setting item provided from the environment setting table construction unit 134 is registered in the environment setting table 142 (see FIG. 5) (step F1).

  As a result of the search in step F1, it is determined whether or not a line having the same setting item as the setting item provided from the environment setting table construction unit 134 is registered in the environment setting table 142 (step F2). If so, the setting value of the corresponding line is overwritten with the setting value provided from the environment setting table construction unit 134, and the process ends (step F3).

  For example, the environment setting table 142 has already registered a line consisting of a set with the setting item “TIME OUT” and the setting value “10”. The environment setting table construction unit 134 sets “TIME OUT”, When a set of “20” is newly provided as the set value, the set value “10” of the set item “TIME OUT” of the environment setting table 142 is overwritten to “20” after execution of Step F3. .

  In addition, since the setting items and setting values that are the parameters that make up the environment setting information have already been registered, when overlapping parameters are accumulated, the higher nodes are more general and the lower nodes are more detailed Assuming that an environment setting file that describes various settings is held, the environment setting file parameters held by lower nodes are preferentially held.

  If it is determined in step F2 that the line having the given setting item is not registered in the environment setting table 142, the given setting item and the set value are combined in the environment setting table 142 as a new line. Is registered and the process ends (step F4).

Through the above procedure, the setting item combining unit 1342 overwrites the setting value or combines the setting item with the setting value and registers the setting item in the environment setting table 142.
(Operation of shaping transmission means)
FIG. 13 is a flowchart illustrating the operation of the shaping transmission unit of the control unit provided in the server.

  With reference to FIG. 13, the operation of the shaping transmission unit 135 provided in the control unit 13 will be described.

  First, the shaping transmission unit 135 is called from the environment setting information generation control unit 131 when the environment setting table construction unit 134 finishes searching the name space directory 154.

  Therefore, since all the nodes included in the environment name 6 for determining the search node in the namespace directory 154 (see FIG. 3) are searched, the environment setting information generation control unit 131 calls the parameters stored during the search. Is prepared for transmission as environment setting information 7 corresponding to the environment name 6.

  The shaping transmission unit 135 refers to the environment setting table 142 (see FIG. 5) (step G1).

  If there is a line in the environment setting table 142, the first line is extracted from the environment setting table 142 (step G2), and the setting item and the setting value of the extracted line are set as the environment setting element name 1434 ("add"). Based on the setting item attribute name 1435 (“key”) and the setting value attribute name 1436 (“value”), it is converted into environment setting information in the XML format (step G3).

  For example, when the setting item of the cut line is “TIME OUT” and the setting value is “20”, the environment setting information is “<add key =“ TIME OUT ”value =“ 20 ”>”.

  The environment setting information converted in step G3 is provided to the environment setting information generation control means 131 for each conversion (step G4).

  Through the above procedure, the shaping transmission unit 135 overwrites the environment setting table 142 by the setting item combining unit 1342 or converts the setting items and setting values registered as a set into environment setting information in XML format. To do.

  After the provision to the environment setting information generation control means 131, the conversion and transmission steps shown in steps G1 to G4 are repeated until there are no more rows in the environment setting table 142.

(Effect of this embodiment)
Hereinafter, effects obtained by the present embodiment will be described.

  The first effect of the present embodiment is that the application program 441 can acquire the environment setting information 7 transparently regardless of the installation location.

  The reason is that the environment setting file having the parameters of the environment setting information is described using XML, which is a general technique, and the environment name is identification information for identifying the parameters constituting the environment setting information by attributes. This is because the server 1 can easily generate the environment setting information 7 based on the environment name 6 that requests the environment setting information 7. In addition, since the environment setting information 7 can be easily generated in this way, the application program 441 acquires the environment setting information 7 generated by the server 1 via the network 5 without requiring a unique action. Because it can.

  That is, the application program 441 can acquire the environment setting information 7 corresponding to the environment name 6 transparently by simply inquiring the server 1 about the environment name 6 regardless of the installation location. In addition, the application program 441 only needs to store only information (DNS name, IP address, etc.) for identifying the server 1 to be inquired and the environment name 6 uniquely determined according to the execution environment. The environment setting information 7 can be acquired.

  The second effect of the present embodiment is that the application program 441 to be executed for each application program, for each user, for each computer, and the various environment setting files necessary for the execution environment can be easily integrated. It can be managed.

  The reason is that in the method of inquiring the environment setting information 7 using the environment name 6, the search destination of the environment setting file is limited to the name space directory 154.

  In the namespace directory 154, since each node holds an environment setting file with inheritance relationships between attributes in the hierarchy of the tree structure, the environment setting file can be managed centrally, Each environment setting file can be managed as a group.

  Further, since the administrator of the server 1 can freely determine the node configuration, the administrator of the server 1 can apply a consistent management policy that does not depend on the application to manage the environment setting file.

  The third effect of the present embodiment is that the environment setting information 7 parameters common to the group (setting items having the same setting value, etc.) are grouped into a group common environment setting file, and the environment setting specific to the group member is set. It can be managed separately from the file. In addition, since a common environment setting file can be collected, the required storage capacity can be reduced.

  Furthermore, the application program 441 does not need to be aware that the parameters of the environment setting information 7 are described in a plurality of environment setting files.

  The reason is that each node of each hierarchy that forms a tree structure and holds the environment setting file is associated with each character string that configures the environment name 6, and groups that share the contents of setting items and the like are summarized. There is inheritance of the parameter attribute of the environment setting information 7 between the environment setting file held by the node (higher node) and the environment setting file of the node (lower node) that is a member of the group, and the server 1 has received it. In order to generate the environment setting information 7 by calculating the contents of each environment setting file having the same element name, setting item name, setting value, etc. extracted based on the environment name 6 by the union from the upper node. is there.

  The fourth effect of the present embodiment is that the directory directory 154 can be freely moved within the file system 15 accessible by the server 1, and thus various directory management can be performed.

The reason is that the environment setting information generation control means 131 associates the root node 2000 of the namespace directory 154 with the current directory at the start of generation of the environment setting information 7 (step B2). This is because even if the directory 154 is moved, if the starting directory (root node) is updated, the environment setting information 7 acquired by the client 4 is not affected.
(Second Embodiment)

  Next, a second embodiment of the present invention will be described in detail with reference to the drawings.

  Referring to FIG. 14, the difference between the first embodiment shown in FIG. 1 and the present embodiment is that the control unit 43 of the client 4 includes a user name acquisition unit 432, a group name acquisition unit 433, Is added.

  The user name acquisition unit 432 is a unit that acquires the name of the user of the client 4 that executes the application program 441 using the function of the OS that is the execution base of the client 4.

  The group name acquisition unit 433 is a unit that acquires the name of the group to which the user of the client 4 that executes the application program 441 belongs, using the function of the OS that is the execution base of the client 4.

(Operation of Second Embodiment)
The operation according to this embodiment will be described.

  In the first embodiment shown in FIG. 1, the environment name 6 is set by the application program 441 (step A1) and input to the environment setting information inquiry means 431 (step A2), but this embodiment shown in FIG. In this form, the environment setting information inquiry means 431 generates the environment name 6 (step H1).

In the following, the application program 441, which will be described in detail with respect to the processing in step H1, which is the difference from the operation of the client according to the first embodiment, is inputted with its own application name, and thereby the environment setting information inquiry means 431. Change the behavior to call.

  The environment setting information inquiry unit 431 acquires the name of the user of the client 4 who executes the application program 441 using the user name acquisition unit 432, and further executes the application program 441 using the group name acquisition unit 433. The name of the group to which the user of the client 4 belongs is acquired.

  The boundary setting information inquiry unit 431 includes an application name, a group name, an application name input from the application program 441, a user name acquired by the user name acquisition unit 432, and a group name acquired by the group name acquisition unit 433. The environment name 6 is generated by concatenating with “. (Period)” in the order of the user name, and the environment setting information 7 is queried.

  For example, referring to FIG. 3, when the application name is “editor”, the name of the user who executes “editor” is “admin”, and the name of the group to which “admin” belongs is “host”, the environment name 6 "Editor.host.admin" is generated.

(Effect of this embodiment)
In this way, in the present embodiment, the application program 441 executes the application program 441 without being aware of the environment name by the mechanism for automatically generating the environment name 6 inside the environment setting information inquiry means 431. The environment setting information 7 can be inquired according to the user who performs the operation.

  Next, the functional configuration of the client according to the present invention will be described.

  In the client 4, the application program 441 stored in the auxiliary storage unit 404 is loaded into the main storage unit 402 and executed on the CPU 401, whereby the environment setting information is generated via the function and communication unit that generate the environment name 6. A function for performing processing for inquiring 7 is provided.

  That is, the client 4 according to the present invention not only realizes its operation in hardware, but also loads an application program 441 that executes each of the above-described means and units into a CPU 401 (control unit 43) that is a computer processing device of the client 4. ) Can be realized in software. The application program 441 is stored in an auxiliary storage unit 404 (storage unit 44) including a magnetic disk, a semiconductor memory, and other recording media, loaded from the auxiliary storage unit 404 to the CPU 401, and controls its operation. Each function described above is realized.

  In addition, the server 1 according to the present invention also realizes the functions of each unit and each unit such as the environment setting information generation control unit 131 and the environment name decomposing unit 132 by the program that executes each unit and each unit as described above.
