Below are the steps for applying quarterly PSU patch on Oracle 11g database.

1. Download the patch from Oracle support portal.


2. Validate patch version:

opatch utility is used to apply patches to the database. So before applying patch, we need to check whether the existing opatch version is supported for the patch or not.

So refer the readme file of the patch for the minimum supported version.

As per patch read me file:

1.2.1 OPatch Utility
You must use the OPatch utility version or later to apply this patch. Oracle recommends that you use the latest released OPatch version for 11.2, which is available for download from My Oracle Support patch 6880880 by selecting the release.
For information about OPatch documentation, including any known issues, see My Oracle Support Document 293369.1 OPatch documentation list.

So for this patch , the opatch version should be or later.

Lets check the existing opatch version in database.

Existing version is, lower than the required one. So we need to install the required opatch utility.
