Welcome aboard at Oracle, Alex Zaballa

Our PM team is slowly growing – and I am so happy about our newest team member. Welcome aboard at Oracle, Alex Zaballa!

Now I think I need to start learning a bit more Portuguese. Rodrigo is located in Brazil, and Alex relocated a while ago to the US but is Brazilian as well. I am really excited to have another super-smart guy in our team helping us with upgrades, (cloud) migrations, patching, Cloud Migration Advisor and CPAT, and other cool things. Personally, I enjoy working with people who have such a deep knowledge …

Ouch … again OCM

Another customer, another upgrade – and again from Oracle Database to Oracle Database And again an OCM error during upgrade which is not very obvious to relate to OCM once you see the errors during upgrade.

While monitoring the database during upgrade with tail -f on the alert.log we’ve spotted this one here:

ORA-604: error occurred at recursive SQL level 3
ORA-904: "XDB"."DBMS_CSX_INT"."GUIDTO32": invalid identifier
XDB SGA reset to NULL.

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

OCM is the Oracle Configuration Manager, a tool to proactively monitor your Oracle environment to provide this information to Oracle Software Support. As OCM is installed by default in many databases but is some sort of independent from the database’s version you won’t expect any issues during or after a database upgrade 😉

But after the upgrade from Oracle to Oracle on Exadata X2-2 one of my customers found the following error in the alert.log every 24 hours:

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_1"
ORA-29280: invalid directory path
