Upgrading from 11.2.0.1 to 11.2.0.3 with in-place upgrade for RAC

Two previous blog posts showed steps to upgrade from 11.2.0.1 to 11.2.0.2 and 11.2.0.2 to 11.2.0.3. Earlier posts all had out of place upgrades for a single node cluster stack. This post is for a two node cluster with out of place upgrade for Grid Infrastructure (GI) and in-place upgrade for Oracle Home.

Following text is from GI install guide (sections that relates to the upgrade).
"Oracle recommends that you leave Oracle RAC instances running. When you start the root script on each node, that node's instances are shut down and then started up again by the rootupgrade.sh script. If you upgrade from release 11.2.0.1 to any later version (11.2.0.2 or 11.2.0.3), then all nodes are selected by default. You cannot select or de-select the nodes. For single instance Oracle Databases on the cluster, only those that use Oracle ASM need to be shut down. Listeners do not need to be shut down."

"Oracle recommends that you select all cluster member nodes for the upgrade, and then shut down database instances on each node before you run the upgrade root script, starting the database instance up again on each node after the upgrade is complete. You can also use this procedure to upgrade a subset of nodes in the cluster."

"Oracle recommends that you upgrade Oracle ASM at the same time that you upgrade the Oracle Clusterware binaries. Until Oracle ASM is upgraded, Oracle databases that use Oracle ASM cannot be created. Until Oracle ASM is upgraded, the 11g release 2 (11.2) Oracle ASM management tools in the Grid home (for example, srvctl) will not work."

"At the end of the upgrade, if you set the OCR backup location manually to the older release Oracle Clusterware home (CRS home), then you must change the OCR backup location to the Oracle Grid Infrastructure home (Grid home). If you did not set the OCR backup location manually, then this issue does not concern you."

"To upgrade existing 11.2.0.1 Oracle Grid Infrastructure installations to Oracle Grid Infrastructure 11.2.0.2, you must first verify if you need to apply any mandatory patches for upgrade to succeed. Refer to Section F.6 for steps to check readiness.
To upgrade existing Oracle Grid Infrastructure from 11.2.0.2, to 11.2.0.3 or later, you must apply patch 11.2.0.2.1 (11.2.0.2 PSU 1) or later.
"

From the upgrade guide
"Known Issue with the Deinstallation Tool for This Release
Cause: After upgrading from 11.2.0.1 or 11.2.0.2 to 11.2.0.3, deinstallation of the Oracle home in the earlier release of Oracle Database may result in the deletion of the old Oracle base that was associated with it. This may also result in the deletion of data files, audit files, etc., which are stored under the old Oracle base.
Action: Before deinstalling the Oracle home in the earlier release, edit the orabase_cleanup.lst file found in the $Oracle_Home/utl directory and remove the "oradata" and "admin" entries. Then, deinstall the Oracle home using the 11.2.0.3 deinstallation tool.
"

Combination of patches used in the two upgrades mentioned above are not needed here (9706490 or 12539000). 11.2.0.1 to 11.2.0.2 ASM Rolling Upgrade [ID 1274629.1] has a new section for upgrading to 11.2.0.3.

Cluster verification utility can check the required patches for the platform before the upgrade. For Linux x86_64 the required patch was 9413827. Running cluvfy with pre upgrade mode would check the pre-reqs needed. Only two stood out in this case
Checking for Oracle patch "9413827" in home "/opt/app/11.2.0/grid".

After applying the required patch and running the fixup script all the checks passed.

By default all the nodes are selected but cluster could be upgraded in a rolling fashion.

Select a new location for the out of place upgrade

The rolling upgrade begins with the running of rootupgrade.sh. Up until this point the exisitng cluster was up and running. Running rootupgrade.sh one node at a time will achieve the rolling upgrade.

To illustrate the rolling upgrade one instance is shutdown before the running of rootupgrade.sh (this is not necessary as rootupgrade.sh will shutdown all cluster related resources on the node which rootupgrade.sh is run).

Inplace upgrade would require all instances to be shutdown.
