Filter the job log to a database file

If the job log is directed to a database file through use of the QMHCTLJL API, additional message filtering can be specified.

The message filtering specified through this API is applied when the job ends and the records for the messages are being written to the file. Up until this time, the messages which are now filtered have appeared. Thus they can be seen while the job is running. When the job log is written, the messages which are filtered will have no records written to the file for them. Thus, even though they appear while the job is running they will not appear in the final file that is produced.
