Hi all,

We are working with a third-party ERP system using Oracle databases, and a
basic installation of it sets up some default scheduled jobs.  We've never
had a problem on 8i or 9i on NT, but after a recent 9.2.0.3 install on
Solaris 8 we found that none of these jobs would run.  They complete
successfully if we use DBMS_JOB.SUBMIT and they re-schedule appropriately,
but never actually run again.

JOB_QUEUE_PROCESSES is set to 9, and I can see the cjq0 process, along with
j000 through j004.  No errors in the alert log, no trace files anywhere.  A
co-worker set the hidden parameter _JOB_QUEUE_INTERVAL to 10 and bounced the
db, and now the jobs are running correctly.  After setting this parameter, I
now see five entries for 'jobq slave wait' in v$session_wait, but these did
not appear earlier.

Any ideas on why this wasn't working before?  I thought that in 9i the job
queue coordinator default interval was 5 seconds, and that the hidden
parameter was only to be used if a smaller interval was needed.

Thanks in advance,
Beth
