How to Merge Patches Using admrgpch

Couple of things you should consider when it comes to merge patches:

- AD patches can be merged with other AD patches, but AD patches and non-AD patches
cannot be merged.

- You can merge any non-AD patch with any other non-AD patch.

- You can merge patches with their listed prerequisite patches.

- You can merge individual patches with mini-packs and maintenance releases.

- You should not merge patches which have manual steps in them, mostly forms,
workflow, ias patches have manual steps and these need to be applied individually.

- AD Merge Patch will not merge patches of different releases, platforms or parallel
modes

- Check AD Merge Patch log files.
After AD Merge Patch runs, check the admrgpch.log file for errors. The file
is located in the current working directory (where AD Merge Patch was run).

- Create Source and destination directory
Copy all the patche to source directory
and run the below scripts ($ Admrgpch s- -d )
admrgpch -s /home/applmgr/patch10g/source -d /home/applmgr/patch10g/dest
-merge_name srikanth



ADMGRPCH is a utility to merge multiplie patches i.e Auto patch compatable patches into a single integrated patch.

This executable is located in AD_TOP/bin

Syntax: -

Destinitation: – Where admgrpch will create the merged patch.

It reads the all drivers and Readme files and merge into a single driver file

Actions in the merge patch are grouped by product then by patch number.

Log file located in the current directory where we run the admgrpch.

We can merge only same releases, same platforms or same parallel modes and if they are not incompatable patches.
