Abstract

PURPOSE:To quickly restart the operation of a system by deciding automatically the necessity for re-execution of the system operation when the executing conditions are satisfied for the definition of a schedule in a state where the system operation is restarted at the execution of the schedule definition set at the time of the interruption by a fault. CONSTITUTION:This system is provided with a schedule definition file 4, a schedule definition control table 2, a state recording variable table, a schedule definition evolving means 1, a schedule definition executing means 5, a schedule definition executing means 6, and a schedule definition executing state recording means 7. Then it is automatically decided whether the schedule definition whose executing conditions are satisfied after the restart of the system operation should be carried out or not. Thus the system operation can be quickly restarted.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a schedule definition re-execution method.

[Conventional technology]

Conventionally, when execution of a schedule definition is interrupted due to a failure during system operation, it has not been possible to automatically determine whether or not to re-execute each schedule definition.

Therefore, if execution of a schedule definition is interrupted due to a failure during system operation, either the schedule definition that was interrupted due to the failure is re-executed from the beginning, or the execution history of the schedule definition is manually verified and then manually changed. I am trying to run it using the specified schedule definition.

[Invention or problem to be solved]

In the schedule definition execution means described above, the schedule definition execution means
If the schedule definition is changed manually based on the execution history of the schedule definition, the disadvantage is that it takes time to resume system operation because the manual decision is made whether to restart execution of the schedule definition from this point.

Also, to the disorder. When a schedule definition that has been interrupted is re-executed from the beginning, if the execution conditions of the schedule definition are met again, the schedule definition that has already been executed will be executed redundantly, which may cause some inconvenience.

In the present invention, when restarting system operation from the execution state of the schedule definition at the time it was interrupted due to a failure, it is possible to automatically determine whether to re-execute or not when the execution conditions of the schedule definition are met. The purpose is to be able to quickly restart system operations and to prevent inconveniences caused by duplicate execution of schedule definitions.

[Means to solve the problem]

In the schedule definition re-execution method of the present invention, control information for determining whether a schedule definition can be re-executed is read from a schedule definition file, and a schedule definition management table and a status record variable table are developed in the main memory. a schedule definition expansion means for determining the execution of the schedule definition based on the information in the schedule definition management table 1 expanded on the main memory by this schedule definition expansion; I--A schedule definition execution means for executing a schedule definition determined to satisfy the execution conditions by the rule definition execution determination means, and a schedule definition execution means for determining whether the schedule definition not executed by the schedule definition execution means can be re-executed. and a schedule definition execution status recording means for recording control information in a schedule definition file.

〔Example〕

Next, the tree invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the wooden invention.

This schedule definition re-execution method consists of a schedule definition file 4, a schedule definition management table 2, a status recording variable table 3, a schedule definition expansion means 1, a schedule definition execution means 5, and a schedule definition execution means 6. and the schedule file definition execution state recording means 7
Contains.

The schedule definition development means 1 uses the schedule definition file 4 as an input take to develop a schedule definition management table 2 and a status record variable table 3 on the main memory.

The schedule definition execution determining means 5 determines whether the execution conditions of the schedule definition are satisfied whenever a schedule definition substantive condition event occurs.

The schedule definition execution means 6 executes the schedule definition whose execution conditions are determined to be satisfied by the schedule definition execution determination means 5.

The scheduler definition execution state recording means 7 records control information in the schedule definition file 4 for determining whether the schedule definition can be re-executed.

At this time, the schedule definition execution state recording means 7 updates the value of the state record variable number 34 with the value of the state record variable update value 35, and records it in the schedule definition file.

(1) If the schedule definition is re-executable, update the value of the status recording variable that records the execution status of the schedule definition at the start of execution of the schedule definition to a value indicating that re-execution is not possible, and record it in the schedule definition file 4. be done.

(2) When the schedule definition is re-executable When the execution of the schedule definition starts, the value of the status recording variable that records the execution of the schedule definition is updated to a value indicating that the schedule definition is re-executable and is recorded in the schedule definition file 4.

Next, the operation of the schedule definition re-execution method of this embodiment will be explained.

First, the schedule definition development means 1 develops a schedule definition management table 2 as shown in FIG. 3 and a status record variable table 3 as shown in FIG. 4 on the main memory.

At this time, the schedule definition development means 1 develops comparison information of status record variables for determining whether the schedule definition can be re-executed on the schedule definition management table 2 as follows.

(2) Store the number of the status record variable that records the execution status of the schedule definition in the area of status record variable number 31;

(2) An identification number is stored in the area of the status record variable event judgment type 32 without the comparison operator "゛〆".

(2) If the schedule definition cannot be re-executed, a value indicating re-execution is stored in the status record variable event judgment symmetric value 33.

(2) If the schedule definition can be re-executed, a value indicating that re-execution is not possible is stored in the status record variable event judgment symmetric value 33.

Next, the schedule definition execution condition determining means 5 determines the value of the status record variable on the status record variable table 3 corresponding to the value of status record variable number 3 based on the comparison information of the number of status records on the schedule management table 2. It is determined whether or not the execution conditions of the schedule definition are satisfied, with the comparison between the value 33 and the status record variable event determination target value 33 being one of the execution conditions of the schedule definition.

Next, the schedule definition execution condition determining means 5 determines whether the schedule definition execution condition is satisfied every time the schedule definition execution condition event occurs.

The schedule definition execution means 6 executes the schedule definition whose execution conditions are determined to be satisfied by the schedule definition execution means 5.

〔Effect of the invention〕

As explained above, the present invention provides a schedule definition expansion means, a schedule definition execution judgment means, a schedule definition execution means, a schedule definition execution status recording means, a status record variable table, and a schedule definition management database, thereby enabling system operation to be resumed. It becomes possible to automatically determine whether or not to execute a schedule definition whose execution conditions have been met later.

Furthermore, it is possible to prevent inconveniences caused by duplicate execution of schedule definitions after system operation is resumed.
