4.4.2 Options related to job execution
This subsection describes the environment setting items (environment setting parameters) of the job execution environment which you can specify as options for job execution. Set these options according to your operating environment.
For those environment setting parameters of the job execution environment which are not described herein, see 20.5 Setting up the job execution environment in the JP1/Automatic Job Management System 3 Configuration Guide.
For the setting procedure, see 4.2 Environment setting parameter settings in the JP1/Automatic Job Management System 3 Configuration Guide (for Windows systems) or 14.2 Environment setting parameter settings in the JP1/Automatic Job Management System 3 Configuration Guide (for UNIX systems).
- Organization of this subsection
(1) Defining the work path for job execution as a variable
If a different installation path is defined for JP1/AJS3 at each agent host, or if the JP1/AJS3 installation path at an agent host is not defined in the environment variable PATH, by defining the installation path at the agent hosts as a variable, you can enable jobs to be executed regardless of where JP1/AJS3 is installed on the agent.
We recommend that you define the work path for job execution as a variable when JP1/AJS3 runs in different environments; for example, when the executable files for job execution reside on the C drive in one agent host, and on the D drive in another agent host.
For details about setting the work path as a variable, see 6.2.1 Defining variables for work paths used during job execution in the JP1/Automatic Job Management System 3 Configuration Guide (for Windows systems) or 15.2.1 Defining variables for work paths used during job execution in the JP1/Automatic Job Management System 3 Configuration Guide (for UNIX systems).
(2) Executing jobs with long file names (Windows only)
When a job is executed, the name of the executable file is converted to a short file name recognized by NTFS (NT file system) and FAT (file allocation table) volumes. We recommend that you enable this option if you want to run job executable files with long file names without converting them to short file names.
For details about this option, see 6.2.15 Executing a job by using a long file name in the JP1/Automatic Job Management System 3 Configuration Guide.
(3) Setting the pipe communication timeout value for an agent (UNIX only)
A timeout might occur during the pipe communication between agent processes of the job execution control. Possible causes of this timeout are:
-
A large number of jobs were executed at one time.
-
The CPU has a high load.
-
The agent process of the job execution control was swapped out for 300 seconds or longer due to insufficient real memory, and the job was not executed.
If these problems remain unresolved and pipe communication timeout errors are likely to recur, we recommend that you increase the timeout for pipe communication at the host on which the agent processes run.
- Important
-
If the setting for pipe communication timeout is too long, job errors might take longer to detect.
For details about setting the pipe communication timeout, see 15.2.15 Changing the timeout value for pipe communication of the agent in the JP1/Automatic Job Management System 3 Configuration Guide.
(4) Placing restrictions on file transmission
When JP1/AJS3 version 11-00 or above is installed as a new installation, the maximum file size of 3 megabytes is placed on the job# execution result files (standard output and standard error output files).
- #
-
The targeted jobs include PC jobs, Unix jobs, custom jobs, QUEUE job executed on JP1/AJS3, and submit jobs. The event jobs, passing information settings jobs, HTTP connection jobs, flexible jobs, and queueless jobs are excluded.
In the case of result files, data beyond the maximum value is discarded and not transmitted. Note that if you execute a passing information settings job by using a standard output file exceeding the maximum value, the information might not be passed properly.
In such a case, modify the value set for the file transmission restriction. For details about the settings, 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.
