Oracle 11.2.0.3 ORACLE_OCM.MGMT_CONFIG_JOB_2_1 errors in database alert log.

You might get following errors in Oracle database alert log:

Errors in file /u01/app/oracle/diag/rdbms/<database_name>/<instance_name>/trace/<instance_name>_j000_7665.trc:
ORA-12012: error on auto execute of job "ORACLE_OCM"."MGMT_CONFIG_JOB_2_1"
ORA-29280: invalid directory path
ORA-06512: at "ORACLE_OCM.MGMT_DB_LL_METRICS", line 2436
ORA-06512: at line 1


Reason for these errors are Oracle Configuration Manager (OCM).
It will give these errors once a day because it is trying to write directory that does not exist.

You can fix this error with following ways:

If you don't use OSM then:

Drop whole user:
SQL> drop user ORACLE_OCM cascade;
OCM is a standalone, separate tool and removing won't affect the database functionality.

Or just disable OCM jobs (this prevent it's writing attempts):
exec dbms_scheduler.disable('ORACLE_OCM.MGMT_CONFIG_JOB')
exec dbms_scheduler.disable('ORACLE_OCM.MGMT_STATS_CONFIG_JOB')


If you want to use OCM then you need to reconfigure it:
