Software

Download the following software:

Oracle Database 11gR2 (11.2.0.4) (x86_64)

Additional patches are required for some versions of the database. See here.

Cloud Control 12c Installation and Upgrade

For clarity, my starting 12cR3 installation had the following details.

HOSTNAME : ol6-em12cr3.localdomainDB Version: 11.2.0.3 Patched to 11.2.0.4 during this process.ORACLE_SID: DB11GPORT : 1521URL : https://ol6-em12cr3.localdomain:7803/em

There are specific patches for different versions of the database prior to 11.2.0.4, as described here. I took the opportunity to patch to 11.2.0.4. and the latest SPUbefore starting the upgrade.

Make sure the privileges for the DBMS_RANDOM package are as described in the documentation.

export ORACLE_SID=DB11Gexport ORAENV_ASK=NO. oraenvexport ORAENV_ASK=YES

sqlplus / as sysdba

GRANT EXECUTE ON dbms_random TO dbsnmp; GRANT EXECUTE ON dbms_random TO sysman;REVOKE EXECUTE ON dbms_random FROM public;

Make sure there are no invalid objects in the repository database.

SELECT owner, object_name, object_typeFROM dba_objects WHERE status = 'INVALID'AND owner IN ('SYS', 'SYSTEM', 'SYSMAN', 'MGMT_VIEW', 'DBSNMP', 'SYSMAN_MDS');

In my case, there were several invalid objects, so they were recompiled using the following commands.

EXEC UTL_RECOMP.recomp_serial('SYS');EXEC UTL_RECOMP.recomp_serial('DBSNMP');EXEC UTL_RECOMP.recomp_serial('SYSMAN');

Edit the "/etc/security/limits.conf" file, increasing the following entry to 4096 if it is less than that. You will need to reboot after this.
