Oracle Database PSU 11.2.0.3.1

Are you applying CPU 11.2.0.3 then consider applying PSU 11.2.0.3.1 as it contains the latest CPU and all the one-off fixes that makes you in sync with Oracle Support. I always make a practice of applying the latest PSU when upgrading database to the next release.

Patch Set Updates (PSUs) are proactive cumulative patches containing recommended bug fixes that are released on a regular and predictable schedule. PSUs are on the same quarterly schedule as the Critical Patch Updates (CPU), specifically the Tuesday closest to the 17th of January, April, July, and October.

The PSUs serve as a new baseline version for reporting issues to Oracle.

There are two latest PSU available
Patch 13343438 DATABASE PATCH SET UPDATE 11.2.0.3.1 (INCLUDES CPU JAN2012)
Patch 13348650 GRID INFRASTRUCTURE PATCH SET UPDATE 11.2.0.3.1 (INCLUDES DB PSU 11.2.0.3.1)

If you are having the Grid Infrastructure home and other database home you can consider applying Patch 13348650 which includes PSU for both the GI and DB Home.

I applied on the Upgraded ASM Home (GI Home) as root user

cat root.sh 
export ORACLE_HOME=/oracle/product/asm11.2
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH
export PATCHTOP=/dev/stage/if/stage/11gR2/patchset
opatch auto $PATCHTOP -oh $ORACLE_HOME -ocmrf $ORACLE_HOME/asmocm.rsp

The procedure can be used to apply the PSU on the DB Homes as well.
