EM12c upgrade from 12.1.0.2 to 12.1.0.3
Now that Oracle Enterprise Manager Cloud Control 12c Release 3 (aka EM12cR3!) has been out for a few weeks, I decided to brave it and upgrade our Production stack today. In this post, I’ll be upgrading an EM12cR2 (12.1.0.2) installation which consists of two OMSes, running on Linux x86-64 (RHEL5) which uses an 11.2.0.3 database management repository.
