Merge Patches using admrgpch
Admrgph utility is used to merge two or more patches in oracle apps. The
advantage of merging patches is that it reduces downtime as the
repetitive task of compiling invalid database objects, generating forms
and reports,jar files etc.
How to use Admrgpch to merge patches
Download the patches in /patch directory. Now create 2 subdirectory in
/patch say mergesource -which contains the unzipped patches to be
merged and mergedest -which contains the merged patch. Please note that
both mergesource and mergedest should be created as immediate child of
same parent directory say /patch. Now you can execute the following
command to merge the patches.
admrgpch -s <source> -d <dest> -merge_name <mergename>
For example->
admrgpch -s </patch/mergesource> -d </patch/mergedest> -merge_name <amebrup2>
Please make sure the the merge path log file "admrgpch.log" does not
contain any error. If the above command to merge patches completes
successfully then it displays the following->

2 unified drivers merged.
Patch merge completed successfully
Please check the log file at ./admrgpch.log
Now go to the destination merge patch directory say "mergedest". You can
see that the admrgpch already created a driver with name
"u_<mergename>.drv" say u_amebrup2.drv. Now apply the merged patch
as a single patch using adpatch. So you have to give this driver name
u_<mergename>.drv" when prompted.
Restrictions of admrgpch ->
It will not merge patches of different releases,platform,different
parallel modes. Also do not use admrgpch to merge AD and Non-AD patches
ad AD patches will change the patch utility itself.
