Pre-requsite for 11.2.0.1 to 11.2.0.2 ASM Rolling Upgrade

 

 

       This note is to clarify the patch requirement when doing 11.2.0.1 to 11.2.0.2 rolling upgrade.

 

Pre-requsite for 11.2.0.1 to 11.2.0.2 ASM Rolling Upgrade

       There has been some confusion as what patches need to be applied for 11.2.0.1 ASM rolling upgrade to 11.2.0.2 to be successful. Documentation regarding this is not very clear (at the time of writing) and a documentation bug has been filed and documentation will be updated in the future.

There are two bugs related to 11.2.0.1 ASM rolling upgrade to 11.2.0.2:

（1）Unpublished bug 9413827: 11201 TO 11202 ASM ROLLING UPGRADE - OLD CRS STACK FAILS TO STOP
（2）Unpublished bug 9706490: LNX64-11202-UD 11201 -> 11202, DG OFFLINE AFTER RESTART CRS STACK DURING UPGRADE

Some of the symptoms include error message when running rootupgrade.sh:
ORA-15154: cluster rolling upgrade incomplete (from bug: 9413827)
or
Diskgroup status is shown offline after the upgrade, crsd.log may have:

The following are some scenario and corresponding action that may be taken:

1). If $GI_HOME is on version 11.2.0.1.2 (i.e GI PSU2 is applied):

Action: You can apply Patch:9706490 for version 11.2.0.1.2.

Unpublished bug 9413827 is fixed in 11.2.0.1.2 GI PSU2. Patch:9706490 for version 11.2.0.1.2 is built on top of 11.2.0.1.2 GI PSU2 (i.e. includes the 11.2.0.1.2 GI PSU2, hence includes the fix for 9413827). Applying Patch:9706490 includes both fixes. opatch will recognize 9706490 is superset of 11.2.0.1.2 GI PSU2 (Patch: 9655006) and rollback patch 9655006 before applying Patch: 9706490).

2). If $GI_HOME is on version 11.2.0.1.0 (i.e. no GI PSU applied).

Action: You can apply Patch:9706490 for version 11.2.0.1.2. This would make sure you have applied 11.2.0.1.2 GI PSU2 plus both 9706490 and 9413827 (which is included in GI PSU2).


3). If $GI_HOME is on version 11.2.0.1.1 (GI PSU1) (this is rare since GI PSU1 was only released for Linux platforms and was quite old).

Action: You can rollback GI PSU1 then apply Patch:9706490 on version 11.2.0.1.2.

So for all cases, it is recommended to apply Patch:9706490 for version 11.2.0.1.2.

Regardless which situation, opatch may show conflicts with other CRS patch installed in the GI HOME. You need to check if those CRS fixes are already included in 11.2.0.2 or not. Most likely you can rollback those fixes because they are already fixed in 11.2.0.2.
