Job Management Partner 1/Automatic Job Management System 3 System Design (Configuration) Guide

9.1 Limits to prevent system-wide effects from external factors

In JP1/AJS3, you can implement various measures to prevent the processing of specific jobs from affecting the entire system. For example, you can discard out-of-bounds data by setting limits on the size and quantity of external data that is input to JP1/AJS3. You can also output a warning message when a constantly increasing item is nearing its limit.

The following table lists items that increase or decrease due to external factors, and the limits that can be imposed on each item in JP1/AJS3.

Table 9-1 Items affected by external factors and specifiable limits
Category Item Specifiable limit Out-of-bounds processing Message output when the limit is reached
Standard job, action job, custom job, QUEUE job, submit job
 
Size of result files (standard output file, standard error output file)
(manager side)

Size of result files (standard output file; standard error output file)

A warning message is output and the received file is discarded.

KAVU4294-I^#1
KAVU4295-W^#1
KAVU4296-E^#1
Number of jobs Maximum number of jobs in the system;number of warning jobs in the system A warning message is output when the warning value is exceeded. Startup fails if the maximum value is exceeded. KAVU4520-W^#2
KAVU4524-W^#2

Transfer file size
(manager side) Transfer file size A warning message is output and the received file is discarded. KAVU2243-I^#1
KAVU2244-E^#1

Job execution time Timeout period The job is canceled and placed in killed status. None

User job Maximum data segment size per process
(UNIX only) Dependent on the behavior of the user job. None

Communication time Communication timeout value Retry based on the retry settings. KAVU2227-E^#3
KAVU2228-E^#3
KAVU2245-W^#3
KAVU2246-W^#3

QUEUE job, submit job Number of jobs per queue Maximum number of jobs in the queue A warning message is output when the warning value is exceeded. Startup fails if the maximum value is exceeded. KAVU4515-W^#4
KAVU4516-W^#4

Number of queues Maximum number of defined queues Definition error KAVU4522-W^#2

Number of agents Maximum number of defined agents Definition error KAVU4521-W^#2

Number of execution-locked resources Maximum number of defined execution-locked resources Definition error KAVU4523-W^#2

Event job Number of satisfied start conditions Monitoring condition (filter out unexpected events by specifying detailed conditions such as the issuing user name or output of a specific message) An unexpected event never meets a start condition. KAVT0273-W
KAVT0582-W

Event with a start condition Valid range of the start condition Monitoring ends normally. None

Monitoring period Timeout period The job ends abnormally and the status of the start condition is Unmonitored + Ended. None

File Size of the various log files Log file size Data is wrapped around to the next log file. None
#1

The output message depends on the value of the environment setting parameter that specifies the restrictions placed on file reception.

For details about how to limit items such as the size of received files, see 6.2.7 Placing restrictions on file reception in the Job Management Partner 1/Automatic Job Management System 3 Configuration Guide 1 (for Windows systems) or 14.2.7 Placing restrictions on file reception in the Job Management Partner 1/Automatic Job Management System 3 Configuration Guide 1 (for UNIX systems).

#2

You can use the environment setting parameters to change the setting of the maximum number of jobs in the system, the number of warning jobs in the system, the maximum number of definable queues, the maximum number of definable agents, and the maximum number of definable execution-locked resources.

For details about how to change the settings, see 2.3 Setting up the job execution environment in the Job Management Partner 1/Automatic Job Management System 3 Configuration Guide 2.

#3

The output message depends on the values of the environment setting parameters that specify the retry interval and the maximum number of retries when a TCP/IP connection error occurs.

For details about how to specify these values, see 6.2.8 Changing the interval and number of retry attempts when a TCP/IP connection error occurs in the Job Management Partner 1/Automatic Job Management System 3 Configuration Guide 1 (in Windows) or 14.2.8 Changing the interval and number of retry attempts when a TCP/IP connection error occurs in the Job Management Partner 1/Automatic Job Management System 3 Configuration Guide 1 (in UNIX).

#4

You can use the jpqquealt command to change the maximum number of jobs in the queue.

For details about how to change the maximum number of jobs in the queue, see jpqquealt in 3. Commands Used for Special Operation in the manual Job Management Partner 1/Automatic Job Management System 3 Command Reference 2.
