Upgrade Oracle RAC cluster 11.2.0.3 on OEL 6.1 to Oracle RAC cluster 12c on OEL6.5 – Download

Upgrade Oracle RAC cluster 11.2.0.3 on OEL 6.1 to Oracle RAC cluster 12c on OEL6.5 – Download

In the article you will have a look at the guidelines and steps to upgrade an Oracle RAC cluster 11.2.0.3 on OEL 6.1 to Oracle RAC cluster 12c on OEL 6.5. The initial cluster configuration (Oracle 11.2.0.3 on OEL 6.1) is described here. The upgrade comprises the following steps:

  1. Rolling upgrade of the Virtual Box machines (OEL61A and OEL61B) from OEL 6.1 to OEL 6.5 with UEKR3 (kernel 3.8.13-35.el6uek.x86_64)
  2. Upgrade from Oracle 11gR2 11.2.0.3 to Oracle 12c 12.1.0.1 for both GI/RDBMS software. The database upgrade involves a downtime during the upgrade.

The following software will be used:

  1. Oracle VM Virtual Box 4.3.12 – download from here.
  2. Oracle 12c (database, grid, examples) – download from OTN here.
  3. Oracle OEL 6.5 – download from Oracle Software Delivery Cloud (former Edelivery) here.

I upgraded the Oracle VM Virtual Box software, used in the setup here, to the latest version available at the time of writing the article. Thus, henceforth, I will not discuss the Oracle VM Virtual Box software upgrade in the article.

I will use the existing VMs (OEL61A and OEL61B) without any change from the original configuration for the upgrade to OEL65 and Oracle 12c. The only changes are to enable internet access for the duration of the OEL upgrade

Overall, I must admit, I was quite impressed by how easy and smooth the upgrade was compared to similar Oracle RAC upgrades from 9i->10g->11g where I had to spend longer time on MOS (former Metalink) working around upgrade issues.
