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.

	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#3 KAVU4524-W#3

HTTP connection job	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#3 KAVU4524-W#3
	Job execution time	Timeout period	The job is canceled and placed in killed status.	None
	Communication time	Communication timeout value	Retry based on the retry settings.	KAVU2227-E#4 KAVU2228-E#4 KAVU2245-W#4 KAVU2246-W#4
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#5 KAVU4516-W#5
	Number of queues	Maximum number of defined queues	Definition error	KAVU4522-W#3
	Number of agents	Maximum number of defined agents	Definition error	KAVU4521-W#3
	Number of execution-locked resources	Maximum number of defined execution-locked resources	Definition error	KAVU4523-W#3
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

Output messages differ depending on the environment setting parameter specified for placing restrictions 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 JP1/Automatic Job Management System 3 Configuration Guide (for Windows systems) or 15.2.7 Placing restrictions on file reception in the JP1/Automatic Job Management System 3 Configuration Guide (for UNIX systems).

#2

The message differs depending on the environment setting parameter specified for placing restrictions on file transmission.

For details about how to limit items such as the size of transmitted file, see the section corresponding to the OS. For Windows, see 6.2.27 Placing restrictions on file transmission in the JP1/Automatic Job Management System 3 Configuration Guide. For UNIX, see 15.2.24 Placing restrictions on file transmission in the JP1/Automatic Job Management System 3 Configuration Guide.

#3

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 20.5 Setting up the job execution environment in the JP1/Automatic Job Management System 3 Configuration Guide.

#4

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 timeout period, interval of retries, and number of retries for TCP/IP connections in the JP1/Automatic Job Management System 3 Configuration Guide (in Windows) or 15.2.8 Changing the timeout period, interval of retries, and number of retries for TCP/IP connections in the JP1/Automatic Job Management System 3 Configuration Guide (in UNIX).

#5

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 4. Commands Used for Special Operation in the manual JP1/Automatic Job Management System 3 Command Reference.
