1. Why Merging patches ?

2. How could I merge patches ?

a) Download the patches to be merged

b) Review the readme files: Not all the patches can be merged. Also, some patches require manual steps. 

c) Create source / destination directories 
The source and the destination directory must be created in the same directory. The source and the destination directory could have any name. 

[oracle@APPS PATCH_TOP]$ ls
DESTINATION SOURCE

[oracle@APPS PATCH_TOP]$ . /APPS/visappl/APPSORA.env

[oracle@APPS PATCH_TOP]$ admrgpch -s SOURCE -d DESTINATION -merge_name merge1 -logfilemerge1.log

Executing the merge of the patch drivers
-- Processing patch: SOURCE/6012471
-- Done processing patch: SOURCE/6012471

NOTES: 

• A merged patch is applied just like a single patch (using adpatch). 

• The manifest option could be used to let Oracle unzip the zip files during the merging process.

3. Can I merge patches even though some of the patch readmes say that patches must be applied in a specific order?

Yes

4. Remarks on Patches Merging

• Older split patches can be merged with unified drivers;

• Patches can be merged with their prerequisite patches;

• Patches can ONLY be merged for the same release, platform parallel modes;

• If the combination of patches you want to merge is not supported, you will receive a message;

• Merged AD Patches must be done separately and applied before a non AD Patch;

• The admrgpch utility must be run from the directory which contains the "Destination" and "Source" directories;

• NLS patches must be applied (merged or not) after the US patches, however is allowed to merge the US and NLS patches.
