In most cases the problem its auto-resolved, but in other occasions causes the system to freeze and in such case a Manual stop and Cold Start are required to restore the service.

Environment

Release : 12.x and 21.x

Component: Automation Engine:

Database: Oracle

Cause

Oracle database bug, according to Oracle Support the call stack is a close match to Bug 29967980 - ORA-00600 [ktspfmdb:objdchk_kcbnew_3] on DML Query ( Doc ID 29967980.8), 

Resolution

Solution:

Apply the associated fix for Bug 29967980 - ORA-00600 [ktspfmdb:objdchk_kcbnew_3]

 

Workaround:

Cold start of the automation engine to perform a truncate of all the mq tables should avoid the problem for some time, but it will occur again until the Oracle Database is patched.
