Re: Job never start based on schedule

job_queue_processes is an init.ora parameter. You can verify the current setting by
show parameter job_queue_processes
You should also check whether you are using a server parameter file
(abbreviated spfile)

by issuing
show parameter spfile

(from the name of the init.ora it looks like you are using a spfile)

If that returns a file name you are using a spfile instead of init.ora

You should issue
alter system set job_queue_processes scope=memory|spfile|both to change it.

For backup purposes you could
create pfile='<filename>' from spfile

Further info in the docs.
