Upgrade to 11.2.0.3 - OCM: ORA-12012 and ORA-29280

Symptoms:

After updated database to 11.2.0.3, getting following error in alert log:

Errors in file /opt/oracle/diag/rdbms/db/trace/db_j001_26027.trc:
ORA-12012: error on auto execute of job "ORACLE_OCM"."MGMT_CONFIG_JOB_2_2"
ORA-29280: invalid directory path
ORA-06512: at "ORACLE_OCM.MGMT_DB_LL_METRICS", line 2436
ORA-06512: at line 1

Cause:

OCM is the Oracle Configuration Manager, a tool to proactively monitor your Oracle environment to provide this information to Oracle Software Support.
OCM is trying to write to a local directory which does not exist. Besides that the OCM version delivered with Oracle Database Patch Set 11.2.0.3 is older than the newest available OCM Collector 10.3.7 - the one which has that issue fixed.

Solutions:

you'll either drop OCM completely if you won't use it:

SQL> drop user ORACLE_OCM cascade;

you'll disable the collector jobs:

SQL> exec dbms_scheduler.disable('ORACLE_OCM.MGMT_CONFIG_JOB');
SQL> exec dbms_scheduler.disable('ORACLE_OCM.MGMT_STATS_CONFIG_JOB');
