Control information written in a job log

You can control what information the system writes in the job log.

To do this, you specify the LOG parameter on the Create Job Description (CRTJOBD) command. You can change these levels by using the Change Job (CHGJOB) command or the Change Job Description (CHGJOBD) command. Three values make up the LOG parameter: Message level, message severity, and message text level.

The first value, message level, has the following levels:

Level
Description
0
No data is logged.
1
The only information to be logged is all messages sent to the job's external message queue with a severity greater than or equal to the message severity specified. Messages of this type indicate when the job started, when it ended, and its status at completion.
2
The following information is logged:
  • Level 1 logging information.
  • Any requests that result in high-level messages with a severity greater than or equal to the severity specified. If the request is logged, all of its associated messages are also logged.
3
The following information is logged:
  • Logging level 1 and 2 information.
  • All requests.
  • Commands run by a CL program if allowed by the Log CL program commands job attribute and the Log attribute of the CL program.
4
The following information is logged:
  • All requests and all messages with a severity code greater than or equal to the severity specified, including trace messages.
  • Commands run by a CL program if allowed by the Log CL program commands job attribute and the Log attribute of the CL program.
    Note: A high-level message is one that is sent to the program message queue of the program that receives the request. For example, QCMD is an IBM-supplied request processing program that receives requests.

The second value, message severity, specifies the severity level in conjunction with the log level that causes error messages to be logged in the job log. Values 0 through 99 are allowed.

The third value in the LOG parameter, message text level, specifies the level of message text that is written in the job log. The values are:

*SAME
The current value for the message text level does not change.
*MSG
Only message text is written to the job log (message help is not included).
*SECLVL
The message and the message help (cause and recovery) are written to the job log.
