R12.2

[satish]

Hi,

We had recently applied few bugfixes almost 8 patches to our R12.2.5 environment.later we discussed and ran fsclone instead of prepare phase to save the time.it took only 2 hours to complete fsclone.

We wanted to know how fsclone works differently to prepare phase and wanted to know what is synchronising snapshots.

Best regards,
Sri

Hi Sri,

Why don't you get my book? All your questions are answered there.

Here is the link ->

Basically,

In the prepare phase (adop phase=prepare), the file
system gets synchronized. It is an incremental synchronization, so only the required file system objects are copied from run to patch.

When executed with phase=fs_clone, adop re-creates the patch edition file system by copying the active/run file system.

Hi erman,

I had a plan to buy it earlier because you will show some difference compared to others but there are other authors as well so not sure what topics you have covered and what topics they had covered in that book

What about synchronizing snapshots,is it related to database tables?

Other authors? I m not sure about that.
Our book is focused on EBS 12.2.

Anyways;

Watch the videos given in E-Business Suite - ADOP Basic Usage Training Videos [Video] (Doc ID 2103131.1)

Especially, the "prepare video"

-->
This is a video on the PREPARE phase of ADOP.  Some of the highlights of the prepare phase are listed here.  This video will share details of these items.

Gets patching filesystem ready to apply a patch.
Checks that ETCC has been run against the database Oracle Home and that all required patches are applied.
synchronize filesystems - If any configuration changes have been made, this will cause the prepare phase to initiate a fs_clone of the current run filesystem to the patch filesystem.
run autoconfig if necessary.
check tablespaces for sufficient free space before starting.
check APPS_FNDFS listener to make sure concurrent requests will launch.
launch concurrent request - "Online Patching In Progress" (ADZDPATCH).
synchronize snapshots between run and patch filesystems.

Then update me if you will still have concerns.
