Hundred of ORACLE HOME to Patch looking for better way to apply PSU
I have at the most 100 different oracle home (10G ) 10.2.0.4 to be specific on different system and we are taking a project to apply the PSU patches on them and by the process of Applying patch individually It will take lot of time to apply the patch to all the ORACLE HOMES.
By an estimate we are looking more than 100 hr of work if I consider 1 hr for each home (taking backup of old home and some issues if any). And also we need to reduce the down time as well.
I have at least 4 to 10 environment for each application. ASM homes are seperate for each server in RAC and Also we have data guard as well. we do not have GRID CONTROL.
