Possible to change scheduler default job class?

Hi

Oracle 19.6

Linux

Is it possible to change default scheduler job class.

Whenever I create:

• DOMAIN index
• or create materialized view with refresh interval

Then, since I do not explicitly execute SYS.DBMS_SCHEDULER.CREATE_JOB, that oracle does itself, hence I cannot specify JOB CLASS.

At the moment default seems to be: DEFAULT_JOB_CLASS

I would like to change it to: DEFAULT_IN_MEMORY_JOB_CLASS in certain pdb-s, so it does not log all the RUNS (need FAILED_RUNS only)
