Hi Martin, Thank you for the answer. But, I did a search myself on MOS and I found this document; 763680.1. Please have a look below; Now, I cannot patch the server because it's used by someone else in the company, but, I will try this solution hopefully tonight and get back to you. ....... Patch 11724916 is database PSU2, and /depot/patches/11.2/GIPSU2/11724916 applies to both GI and database homes. But for GI PSU 12311357, /depot/patches/11.2/GIPSU2/12311357 applies to GI home, and /depot/patches/11.2/GIPSU2/12311357/custom/server/12311357 applies to database home. If /depot/patches/11.2/GIPSU2/12311357 is specified when applying to database home, the error will be reported. *Wrong command example:* <DB_HOME>/OPatch/opatch napply -oh <DB_HOME> -local /depot/patches/11.2/GIPSU2/12311357 *Correct command example:* <DB_HOME>/OPatch/opatch napply -oh <DB_HOME> -local /depot/patches/11.2/GIPSU2/12311357/custom/server/12311357 .......
