Admrgpch Utility

No comments
Admrgpch utility is provided to merge mutliple application patches into single patch. This can help in saving time and effort for executing many patches again and again.
 
There are some restrictions with AD Merge, it can't be used to merge patches of different releases, platforms or parallel modes.

admrgpch  <source_directory> <destination_directory>

       admrgpch  <-s <source_directory>|-preinstall> -d <destination_directory>
                           [-master <master upgrade driver. Valid only
                                     with -preinstall or -driveronly options>]
                           [-verbose <level>] [-merge_name <pattern>]
                           [-manifest <filename>] [-logfile <filename>]
                           [-driveronly] [-admode]

Where

 -help                                 Print help message.

 -verbose <level>              Can be one of: { 0(SILENT),

Steps for patch merging.

1. Download all the patched which need to be merged.
2. Make a source directory .
    mkdir source_test
3. Unzip all the patches and copy them in source directory.
    source_test
   -bash-3.2$ ls
    16759426  17385991


4. Make a target directory
    mkdir target_test


5. Now run the below command to merge the patches.

 admrgpch -s source_test -d target_test -merge_name test_patch

Log:
Executing the merge of the patch drivers
 -- Processing patch: source_test/16759426
 -- Processing file: source_test/16759426/u16759426.drv
 -- Done processing file: source_test/16759426/u16759426.drv

 -- Done processing file: source_test/17385991/u17385991.drv

Copying files...

Character-set converting files...
  2 unified drivers merged.
Patch merge completed successfully
Please check the log file at ./admrgpch.log.
6. Now do to target directory
    cd target_test
    we can see that the merge patch is created with merged driver file.
$ cd target_test
$ ls
16759426_README.html  17385991_README.html  ad             b17385991.ldt  f17385991.ldt  j16759426_fnd.zip  metadata_files
16759426_README.txt   17385991_README.txt   b16759426.ldt  f16759426.ldt  fnd            j17385991_fnd.zip  u_test_patch.drv


Now use normal adpatch from target_test directory for  application of patches and pass u_test_patch.drv when prompted for driver file.
