Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing technique, and more particularly, to a method and apparatus for setting an operating environment of a program, which is suitable for dynamically changing a program operating environment of an information processing apparatus, and a program.

[0002]

2. Description of the Related Art One or a program executed on a computer refers to setting information stored in a memory or a file (for example, definition parameters and data for defining operations such as the size and number of buffers referred to by the program). When the setting information is changed in an information processing apparatus whose execution (operation environment) is controlled, generally, after the program that is started and operating is terminated, the setting information is updated, and then the setting information is updated. Restarting. This is because if the setting information referenced in the executed program does not match the content of the updated setting information,
This is because a mismatch occurs in the operation of the program.

For example, in a computer system or the like that provides a service that enables remote file access from another server, an operation environment of a program that operates while referring to setting information existing in a file or a memory on a storage medium is provided. If a change occurs, there is a possibility that inconsistency may occur between the setting information referred to by the program and the operation of the program and the setting information. Therefore, the program (process) in the operating state (or the communication state) is temporarily deleted. After the process is terminated, a method is adopted in which the changed contents of the operating environment are reflected in setting information such as a memory or a file, and the program is started again with all necessary changes reflected in the setting information.

In a computer system having a plurality of programs that operate while referring to the same setting information, a communication state is established for cooperative processing such as communication with another server or inter-process communication with another process. (For example, a program that is in communication with a remote server) cannot be terminated, and it is necessary to perform continuous operation. This is because, when the program in communication with the other server is terminated, the cooperation with the other server is interrupted.

On the other hand, it is not preferable for system operation to terminate a program in a communication state which is not related to the change of the setting information every time the setting information of the operating environment of the program is changed. Therefore, terminating / re-executing the program each time reduces the operation efficiency and work efficiency of the system.

Several publications are referred to as a system for dynamically changing parameters and the like. For example, Japanese Patent Application Laid-Open No. Hei 8-305650 discloses a system for dynamically changing information referred to by a machine without stopping the machine. For example, there has been proposed a client-server system capable of performing a machine configuration change operation in a short time without having to stop a related machine when performing a machine configuration change. In this client-server system, machines constituting the system respectively hold information on machines having a logical relationship with the own machine and various types of network setting information in a configuration information management database, and a machine configuration change command is input. Then, after changing the network setting information of the configuration information management database, a machine related to the configuration change is searched, the change information is transmitted to the searched machine, and the configuration information management database is updated on the machine receiving the change information. Things. Further, for example, Japanese Patent Application Laid-Open No. 9-33
No. 0259 discloses a computer system capable of dynamically setting and changing file definition information such as a file name and a layout. The computer system includes a parameter file that holds file definition information as parameter information. Access, and the dedicated task is a program to access the file,
A file access method has been proposed in which a file is accessed by referring to a parameter file upon startup.

[0007]

Accordingly, an object of the present invention is to make it possible to change changed information dynamically without terminating the processing of a program.
An object of the present invention is to provide a method for dynamically reflecting the operating environment of a program, an information processing apparatus, and a program.

[0008]

According to the present invention, which provides means for solving the above-mentioned problems, a storage means for storing setting information referred to by a program running on a computer, and a storage means for storing the setting information in the storage means While holding the update target data for the setting information, corresponding to the update target data, an update disable flag indicating whether the update target data is in an update disable state or an update enable state,
A storage means for storing a setting information management table having at least an unupdated flag indicating whether the data to be updated has not been updated or has been updated, and updating or referring to the contents of the setting information table, A setting information updating unit configured to update the setting information stored in the storage unit with data to be updated held in an information table; and an input / output unit configured to notify the setting information updating unit of an update. The program has update enable / disable information for the data of the setting information referred to by the program, and based on the update enable / disable information, allows the setting information update unit to update the setting information. The setting information updating means sends an update notification from the input / output means and a notification of whether the program can be updated or not. When receiving the setting information, the setting information management table is referred to or updated, and if the setting information management table has not been updated, and there is update target data that can be updated, the setting information management table is held in the setting information management table. And updating the setting information with the update target data. As will be apparent from the following description, the above-mentioned problem is similarly solved by the inventions of the claims.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described. According to the present invention, when an update occurs in the operating environment, the program processing is not terminated, the program is not executed, the communication state not directly related to the change of the setting information is maintained, and the setting referred to by the program is maintained. Information is dynamically changed.

Referring to FIG. 1, a preferred embodiment of the present invention will be described. In order to determine whether or not the setting information 4 referred to by the program 3 can be updated, an update enable / disable notification and a setting It has an information management table 5 and a setting information update process 6, manages the state of updatable / non-updatable, and enables the setting information to be dynamically updated.

That is, in a preferred embodiment of the present invention, setting information 4 stored in storage means such as a memory or a file, which is referred to by a program 3 executed on the computer 1, and setting information 4 And an update impossible flag 7 indicating information indicating whether the update object data is in an update impossible state or an update available state in correspondence with the update object data 9.
A setting information management table 5 having an unupdated flag 8 indicating whether the data to be updated has not been updated or has been updated, and a counter 10 for managing updating of the update impossible flag; The program 3 includes a setting information update process 6 for updating or referencing the contents of the table 5 and updating the setting information with the update target data, and an input / output device 2 for notifying the setting information updating process 9 of an update. It has update enable / disable information of the data of the setting information 4 referred to, and notifies the setting information update process 6 of the update enable / disable of the setting information.

The setting information update processing 6 receives an update notification from the input / output device 2 and a notification of whether or not update is possible from the program 3, refers to or updates the setting information management table 5, and updates the setting information and the program. In order to prevent inconsistency in operation, if there is unupdated data and there is data that can be updated, the processing of the program that is not directly related to the change of the setting information is performed without terminating the processing of the program. Control is performed to update the corresponding setting information with the update target data while maintaining the operation state.

The update target data 9 in the initial state of the setting information management table 5 has the same contents as the corresponding data of the setting information, various flags are set to initial values, and the counter 10 is set by the program 3 according to the setting. In information update processing 6,
The count-up operation and the count-down operation are performed each time an update enable / disable notification is issued. When the value of the counter 10 is a predetermined value (initial value 0), the corresponding update disable flag 7 can be updated. If the value of the counter 10 is different from the predetermined value, the value is set to a value indicating that updating is not possible. The non-update flag 8 is a value indicating that the data to be updated has not been updated. When there is no update, or when the updated content is reflected in the setting information 4 with respect to the non-updated data, a value indicating that the data has been updated is used. To the setting information update processing 6 as an update notification. The setting information update processing 6 receives the update notification from the input / output device 2, searches the setting information management table 5,
When the corresponding update target data is updated, and the value of the update disable flag 7 corresponding to the update target data 9 is a value indicating that the update is possible, the update target data 9 is reflected in the setting information 4 and the update disable flag 7 is updated. When the value is a value indicating that updating is not possible, both the setting information 4 and the setting information management table 5 are not updated, and control is performed to set the non-update flag 8 corresponding to the relevant update target data to a value indicating non-update.

[0014] When a change occurs in the update enable / disable state of the setting information referred to by the program 3, the program 3 issues a change enable / disable state of the data whose status has changed to a setting information update process 6. When the setting information update process 6 receives the update enable / disable notification from the program, the setting information update process 6 searches the setting information management table 5 using the notified data as a key, and the update information is the update enable notification. in case of,
The unupdated flag 8 corresponding to the corresponding update target data
Is an unupdated value, the relevant update target data is reflected in the setting information 4, and after the reflection, the unupdated flag 8 is updated to a value indicating that the update has been performed, and the update impossible flag 7 is updated to a value indicating that the update is possible. When the non-update flag 8 indicates that the update has been completed, only the update-impossible flag 7 is set to be updatable. When the notification content is an update-impossible notification, the corresponding update target data in the setting information management table 5 is updated. The update impossible flag 7 corresponding to No. 9 is set to be unupdateable, and the setting information referred to by the program is a state where the unupdated data exists and is in an updatable state (the setting information is (Can be updated with update target data).

In another embodiment of the present invention, the setting information updating process 6 includes an access control process 12 for controlling access of the program to the setting information. In the case where the update target data that has not been updated and cannot be updated exists in the table 5, when the update impossible notification is received from the program 3, the counter 10 corresponding to the update target data 9 is not counted and the access is performed. The control process 12 puts the program that has issued the update-disabled notification in a waiting state, and enables only the update-enabled notification from the program whose update-disabled flag 7 is currently not updated, so that the update-disabled flag 7 can be updated. Is made, and the updated data is reflected in the setting information 4.

The waiting state of the program is controlled by the access control processing 12 until the setting information is updated with new update data and the corresponding update impossible flag becomes updatable. After the update data is reflected in the setting information, the setting information management table 5
Is changed to the updated value, the operation of the program set in the waiting state is resumed by the access control processing 12, and the update rejection notification received earlier is set in the setting information management table 5 To reflect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to explain the above-mentioned embodiment in more detail, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the configuration of one embodiment of the present invention. The present invention includes a computer 1 and an input / output device 2.

The computer 1 sends an update enable / disable notice 11
A setting information 4 referred to by the program 3, a setting information management table 5 for realizing dynamic reflection of the operating environment, a setting information update process 6 for reflecting update data in the setting information 4, Having.

The input / output device 2 notifies the setting information update processing 6 of the computer 1 of an update.

The program 3 refers to the setting information 4 referred to.
, And notifies the setting information update process 6 as an update enable / disable notification 11.

The setting information table 5 contains data 9 to be updated.
A non-update flag 7 indicating whether information is in an update-disabled state or an update-enabled state, a non-update flag 8 indicating information on whether the update target data 9 is not updated or has been updated,
An update target data 9 of the setting information 4 and a counter 10 for managing the update of the update impossible flag 7 are provided.

The contents of the setting information table 5 are referred to / updated by a setting information updating process 6.

The setting information update process 6 receives an update notification from the input / output device 2 and updates / disables from the program 3.
The rejection notice 11 is received.

After receiving the notification, the setting information update processing 6 refers to or updates the setting information management table 5, and if there is unupdated data so as not to cause a mismatch between the operation of the setting information 4 and the operation of the program 3, In addition, when there is data that can be updated, without changing the processing of the program 3, only the changed information is dynamically stored while maintaining the communication state not directly related to the change of the setting information 4. Reflected in setting information 4.

FIGS. 2 and 3 are flow charts for explaining the operation of one embodiment of the present invention. The operation of the embodiment of the present invention will be described with reference to FIGS.

First, the setting information management table 5 will be described. The setting information management table 5 is created before the operation (activation) of the program 3. The update target data 9 when the setting information management table 5 is created has the same contents as the setting information 4.

The update impossible flag 7 and the non-update flag 8 corresponding to the data 9 to be updated are set to "0" as initial values. The update impossible flag 7 is set to a value “1” when the update target data 9 cannot be updated, and set to a value “0” when the update target data 9 can be updated.

Since the plurality of programs 3 may refer to the same data on the setting information 4, the counter 10 counts up and down each time an update enable / disable notification is received. Do the processing,
Only when the value of the counter 10 becomes "0", the update impossible flag 7 is set to "0" (update possible), and when the value of the counter 10 is "1" or more, "1" (update impossible). Set to. The initial value of the counter 10 is “0”.

The non-update flag 8 is "1" when an update has occurred in the data 9 to be updated, when there is no update, or when the update information is reflected in the setting information 4 for the non-updated data (ie, "0" when the data corresponding to the setting information 4 is updated with the update target data in the unupdated state on the setting information management table 5).

First, the operation when the setting information update processing 6 receives an update notification (of FIG. 1) from the input / output device 2 will be described. FIG. 2 schematically shows a processing procedure when the setting information update processing 6 receives an update notification from the input / output device 2 in one embodiment of the present invention.

When the operating environment of the program is updated, the input / output device 2 updates the data to be updated with the setting information update processing 6
Is notified as an update notification.

After receiving the update notification from the input / output device 2, the setting information update process 6 searches the setting information management table 5 for relevant information using the notified data as a key (step S1), The data 9 is transferred to the input / output device 2
The data is updated with the notified data (step S2).

For example, when the input / output device 2 notifies that the data “11” of the setting information 4 is to be updated to “99”, the setting information update processing 6 performs the processing shown in FIG. The update target data 9 on the setting information management table 5 is updated from "11" to "99" (data notified from the input / output device 2).

After updating the setting information management table 5, the setting information updating process 6 refers to the update impossible flag 7 of the data 9 to be updated, and sets the value of the update impossible flag 7 to "0" (updatable).
If so, the relevant update target data is reflected on the setting information 4 (step S4).

The value of the update impossible flag 7 is "1" (update not possible)
In the case of, if the update processing is performed during the reference and processing of the program, there is a possibility that an incorrect operation may occur. Therefore, both the setting information 4 and the setting information management table 5 are not updated, and as shown in FIG. The non-update flag corresponding to the relevant update target data is set to "1" (not updated) (step S5).

Next, the operation when the setting information update processing 6 receives an update enable / disable notification from the execution program will be described. FIG. 3 schematically illustrates a processing procedure when the setting information update processing 6 receives an update enable / disable notification from a program in one embodiment of the present invention.

The program 3 stores the setting information 4 referred to.
When a change occurs in the update enable / disable state of the data, the setting information update process 6 updates / updates the data whose state has changed.
Notify the unacceptable information. In the setting information update processing 6, after receiving the update enable / disable notification, the notified data is used as a key.
The corresponding information in the setting information management table 5 is searched (step S11) to prepare for reference / update of the flag of the notified update target data.

After the search, the contents of the notification are determined (step S1).
2) If it is an update enable notification, the non-update flag 8 of the relevant update target data 9 is referred to (step S13).

When the unupdated flag 8 is “1” (unupdated), there is update data, but the update information is not yet reflected in the setting information 4. Reflected in the setting information 4 (step S15), and after the reflection, the non-update flag 8 is set to "0" (updated), and the update impossible flag 7 is updated to "0" (update enabled) (step S1).
6, S17).

For example, as shown in FIG. 3A, the setting information table 5 has not been updated (the non-update flag 8 is "1") and
It is assumed that there is update target data 9 of “99” that cannot be updated (the update impossible flag 7 is “1”). At this time, if there is a notification that the data of the setting information 4 corresponding to “99” in the setting information management table 5 can be updated, the setting information update processing 6
"99" is reflected in the setting information 4, the non-update flag 8 is set to "0" (updated), and the update impossible flag 7 is set to "0" (update possible).
Update to

When the non-update flag 8 is "0" (updated), as shown in FIG. 3B, even if the notified update target data can be updated, the update target data is updated. Since it has not been performed, the reflection processing for the setting information 4 becomes unnecessary, and only the update impossible flag 7 of the setting information management table 5 is updated to “0” (updatable).

If the content of the notification is an update-impossible notification, the corresponding update-impossible flag 7 in the setting information management table 5 is updated to "1" (update-impossible) as shown in FIG.

As described above, the setting information 4 referred to by the program 3 is updated when unupdated data exists and the data to be updated of the setting information 4 is in an updatable state.

The setting information 4 is updated only when an update notification from the input / output device 2 and an update enable / disable notification from the program 3 are received, by checking the flag of the setting information management table 5 and satisfying the above conditions. Only if you do.

At the time of termination, the computer 1 checks whether all the data to be updated has been reflected in the setting information 4 and if there is any data that has not been updated (the data to be updated whose non-update flag is “1”). After reflecting this in the setting information 4, the process ends.

Next, another embodiment of the present invention will be described. FIG. 4 is a diagram showing the configuration of the second exemplary embodiment of the present invention. As shown in FIG. 4, the second embodiment of the present invention is the same as that of FIG.
In addition to the above-described embodiment shown in FIG.
It has. Other configurations are the same as those of the first embodiment. The access control unit 12 controls access to the setting information 4 of the program 3.

The setting information update process 6 does not perform the count-up process on the counter 10 when the update information 9 that has not been updated and cannot be updated is received in the setting information management table 5 and receives the update impossible notification. Then, the access control means 12 of the setting information update processing 6 puts the program 3 which has issued the update disable notification into a waiting state.

Then, by enabling only the update enable notification from the program whose update disable flag 7 is currently disabled, a timing for making the update disable flag 7 always "0" (update enabled) is created. The updated data is reflected on the setting information 4.

For example, the setting information management table 5 corresponds to FIG.
4, when the update notification for changing “11” to “99” comes from the input / output device 2 as shown in FIG. 4, the setting information management table 5 becomes the state of FIG. .

When the setting information management table 5 is in the state of FIG. 4, as shown in FIG. 4, a program different from the program in which the update impossible flag 7 is currently in the update impossible state is changed to "11". When an update refusal notification is received for the access control unit 1 as shown in FIG.
2 waits for the operation of the program that has issued the update disable notification.

This waiting state is controlled by the access control means 12 until the setting information 4 is changed to new information and the update impossible flag 7 becomes "0" (updatable).

In the setting information update processing 6, after the unupdated data is reflected in the setting information 4, the non-update flag 8 of the setting information management table 5 is set to "0" (updated), as in the embodiment of FIG. And the access control unit 12 restarts the operation of the program in the waiting state, and reflects the update rejection notification received earlier in the setting information management table 5.

According to this embodiment, the timing at which the unupdated data is reflected in the setting information 4 is set, and the update of the setting information 4 is reliably performed in response to the update delay of information frequently referred to from a plurality of programs. To achieve.

Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the configuration of the above embodiment, and can be made by those skilled in the art within a range according to the principle of the present invention. Needless to say, various changes and modifications are included. For example, the computer is not limited to a single computer, but can be applied to a computer system in which a plurality of computers are connected to a network, such as a client server system. In other words, the above-described implementation is also applicable to dynamic changes in the operating environment of a plurality of processes or a plurality of processors operating with reference to setting information such as a shared memory or a plurality of processes operating distributed among a plurality of computers. It can be applied according to the same principle as the example.

[0056]

As described above, according to the present invention,
When a change occurs in the operating environment of a program that operates while referring to setting information present in a file or memory on a storage medium, the management information table for setting information referred to by the program is directly related to the change in setting information. It is possible to dynamically change only the changed information without terminating the processing of the program while maintaining the communication state not to be maintained. For this reason, according to the present invention, the operation efficiency in a computer system or the like sharing a file is particularly improved.
