Ghost Job in DBA_SCHEDULER_RUNNING_JOBS Does Not Let AQ to Submit New PL/SQL/NTFN Job (Doc ID 2274785.1)

Last updated on AUGUST 24, 2021

Applies to:

Oracle Database Cloud Service - Version N/A and later
Oracle Database - Enterprise Edition - Version to [Release 12.1 to 12.2]
Oracle Database Cloud Schema Service - Version N/A and later
Gen 1 Exadata Cloud at Customer (Oracle Exadata Database Cloud Machine) - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Information in this document applies to any platform.


Scheduler job does not work as expected when ORA-4031 is reported due to lack of memory.

In such case a running scheduler job dies suddenly, however its entry is still shown in DBA_SCHEDULER_RUNNING_JOBS. This is like a GHOST entry.

The presence of ghost job in DBA_SCHEDULER_RUNNING_JOBS does not let AQ to submit any new plsql ntfn job, as a result messages remains in ready state and notifications are not sent.

But there is no session ID and no process ID associated with the job.
