Abstract

PURPOSE:To change production of a system without interrupting the system operation by loading the selected information among those system production environment part information that can be dynamically changed by a system production means into a specific table. CONSTITUTION:In a transaction processing system 11, the system production environment part information that can be dynamically changed is produced by a system production means 2 and stored in a file 5 for system production environment part information for each request of a dynamic change request indication 3 for executing environment of the system 11 by a table 10 for system production environment part information. The table 10 is included in the system 11 and defines an executing environment that can be dynamically changed based on the information of the means 2. Then a change information selecting means 8 selects the files 5 based on an operating function command given from an input means 6 and a change information loading means 9 loads the system production environment part information into the table 10 based on the selected file 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system creation and modification method, and more particularly to a system creation and modification method for a transaction processing system.

[Conventional technology]

Conventionally, in this type of system-generated change method, a system-generated table that defines the execution environment corresponding to all system-generated elements is generated within the transaction processing system, and when changing system generation, this system-generated table is used. had to be changed.

This system-generated table cannot be changed while the transaction processing system is running, so if you want to change the system-generated elements to redefine the execution environment, the system-generated elements have the property of being able to be changed dynamically. Regarding the system generation environment section information, the operation of the transaction processing system had to be interrupted several times by performing processing such as terminating the transaction processing system in operation and disconnecting subordinate terminals.

[Problem that the invention seeks to solve]

In the conventional system generation change method described above, even if the system generation environment section information is changed while the transaction processing system is running, the information about the change cannot be dynamically reflected in the transaction processing system as the execution environment. A drawback is that the operation of the transaction processing system must be temporarily interrupted whenever any system generation element is changed.

In view of the above-mentioned points, an object of the present invention is to be able to dynamically change system generation environment part information even when a transaction processing system is in operation without interrupting operation, and to transfer the information of the change to the execution of the transaction processing system. The objective is to provide a system generation change method that can be reflected in the environment.

[Effect]

In the system generation change method of the present invention, the system generation means generates system generation environment part information, which is a system generation element that can be dynamically changed in the transaction processing system, and the system generation environment part information table is dynamically changed in the transaction processing system. An execution environment that can be changed automatically is defined based on the system generation environment section information, and the system generation environment section information that the change information selection means loads into the system generation environment section information table is defined as the system generation environment generated by the system generation means. Select from the section information,
The change information loading means loads the system generation environment information selected by the change information selection means into the system generation environment information table.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the system generation change method of the present invention. A source program 1 that has been installed, a system generation source image is generated based on the source program 1, and system generation environment section information, which is a system generation element that can be dynamically changed in the transaction processing system 11 based on a change request instruction 3, is generated. A system generating means 2 to generate a system, a change request instruction 3 in which an instruction for requesting dynamic change of the execution environment of the transaction processing system 11 is written, and a transaction processing system 1 based on the source program 1.
A system generation source image file 4 in which all the initial system generation elements of 1 are stored, and a system generation environment in which system generation environment section information generated by the system generation means 2 is stored for each change request of the change request instruction 3. section information file 5, and the operator of the transaction processing system 11 uses an operation function command (instructing selection of which system generation environment section information file 5 to apply when changing the execution environment while the transaction processing system 11 is running. The transaction processing system 11 includes an input means 6 for inputting commands) and a transaction processing system 11.

The transaction processing system 11 has a communication processing means 7 that performs communication processing with the input means 6, and a system generation environment information file 5 in which system generation environment information to be loaded into the system generation environment information table 10 is stored. In the transaction processing system 11, the change information selection means 8 selects based on a command, the change information loading means 9 loads system generation environment information into the system generation environment information table 10 based on the selection of the change information selection means 80. It is configured to include a system generated environment information table 10 that defines an execution environment that can be dynamically changed based on system generated environment information.

Referring to FIG. 2, the processing of the system generation means 2 includes a system generation source image file creation step 21;
The process includes a change request instruction existence determination step 22, a system generation environment information file correspondence step 23, and a system generation environment information file creation step 24.

Referring to FIG. 3, the process of the change information selection means 8 includes an operation function command determination step 31, a system generation environment information file search step 32, a system generation environment information file allocation step 33, and an operation function command determination step 31. It consists of a fraudulent message sending step 34.

Referring to FIG. 4, the process of the change information loading means 9 is as follows:
It consists of a change information selection means takeover step 41 and a system generation environment section information load step 42.

Next, the operation of the system generation/change method of this embodiment configured as described above will be explained.

When constructing the transaction processing system 11, the source program 1 is first read, and the system generation source image file 4 is created by the system generation means 2 based on this source program 1 (step 21).
), the information of this system-generated source image file 4 is loaded into a system-generated table (a table that defines the initial execution environment of the transaction processing system 11, not shown) in the transaction processing system 11.

Next, it is determined whether the change request instruction 3 exists and needs to be read together with the source program 1 (step 22).

If it is determined that there is no change request instruction 3, the processing in the system generation means 2 ends.

If there is a change request instruction 3 in the judgment at step 22,
Correspondence for creating the system generated environment information file 5 corresponding to change request instruction 3 (corresponding to one or more system generated environment information files 5 corresponding to one or more change requests in change request instruction 3) (addition of identification information) is performed (
Step 23), system generation environment section information is generated based on the change request instruction 3, and one or more system generation environment section information files 5 for storing it are created by the system generating means 2 (step 24).

When it becomes necessary to change the execution environment while the transaction processing system 11 constructed in this way is in operation, the operator sends the change information selection means 8 from the input means 6 via the communication processing means 7 to the change information selection means 8. A function command is input, and a selection is made as to which system generation environment information file 5 to apply.

The change information selection means 8 determines whether the format of the command, the specification of the system generation environment information file 5, etc. of the input operation function command are appropriate (step 31).

If this judgment indicates that the operational function command is appropriate, the system generation environment information file 5 matching this operational function command is searched and it is determined whether or not it exists (
Step 32).

System generation environment information file 5 that matches this determination
exists, the discovered system generated environment information file 5 is allocated to the transaction processing system 11 (control of the discovered system generated environment information file 5 is passed to the change information loading means 9) (
Step 33).

If the matching system generation environment information file 5 does not exist as determined in step 32, a message is sent to the input means 6 via the communication processing means 7 to the effect that the process of inputting the operational function command is invalid. (Step 3
4).

Even if it is determined in step 31 that the operational function command is not appropriate, the process in step 34 is performed.

The process of step 33 in the change information selection means 8 is taken over by the change information loading means 9 (step 41), and the change information is stored in the system generation environment information file 5 discovered in step 32 in the system generation environment information table 10. The system generation environment information is loaded (step 4).
2) ,) Reconstruction of the ranzagion processing system 11 is performed.

Through the procedure described above, the system generated environment information is changed even while transaction processing is in operation (that is, dynamically), and the execution environment of the transaction processing system 11 is changed. In this case, which system generation environment file 5 is used to change the execution environment of the transaction processing system 11 is determined at will by the operation function command instructed by the operator from the input means 6. You can choose.

〔Effect of the invention〕

As explained above, by providing a change information loading means, the present invention can dynamically change the system generation environment part information even when the transaction processing system is in operation, and it is possible to easily rebuild the transaction processing system. It has the effect of being able to.

In addition, by providing a change information selection means that can freely select the system generation environment section information, it is possible to start the execution environments of various transaction processing systems without interrupting operations. However, it also has the effect of shortening processing time and simplifying processing when setting up a test environment.
