You can increase the logging level of a job by doing the change job. Just follow these steps to change the job and then you can log the maximum amount of information in the job log specific to the running job.

1. Type the following command and press F4.
   CHGJOB LOG(4 00 *SECLVL) LOGCLPGM(*YES)
   In the above Change job (CHGJOB) command, the LOG parameter is known as the message logging parameter where you specify the message logging values which is then used to determine the amount and type of information sent to the job log by this job.
   The parameter has three elements: the message or logging level, the message severity, and the level of message text.
   element 1: the possible logging levels are 0-4.
   element 2: the possible value for message logging severity is (0-99).
   element 3: the possible values for message text are *MSG, *SECLVL, and *NOLIST.In the above command, we set the level as 4, Severity as 00, and Text as *SECLVL. Also, the LOGCLPGM parameter is set to *YES to log the CL program commands.
2. Press Enter to change your job.
3. If you are trying to change any other specific job running in batch mode or any other user job then you may also need to input Job details such as Job name, Job number, and Job user to this command and then press Enter.
   CHGJOB JOB(number/jobuser/jobname) LOG(4 00 *SECLVL) LOGCLPGM(*YES)
   Note: The above command will ensure that the maximum amount of information gets logged in the specific user job log.
