Re: Patchset installation

When I am installing the patchset I am giving oracle the new home. For example:

1. My home is /u01/app/oracle/product/8.0.4
2. I copy all the tree under the home to the new home: /u01/app/oracle/product/8.0.4.4
3. For the patch installation session I set: ORACLE_HOME=/u01/app/oracle/product/8.0.4.4, and install the patch, relink, ... . All the linked libreries are with respect to the new home. In the meantime the running instance has no idea of the new home, but uses /u01/app/oracle/product/8.0.4.
4. When I am done with 3, I shutdown the instance change ORACLE_HOME==/u01/app/oracle/product/8.0.4.4 and start the instance.

This is very similar to installing a new database version distribution parallel to the existing one, which is a standard procedure, and one of the features of the OFA standard.
