Step by step Oracle Apps R12.1.3 Rapid Cloning

Step by step Oracle Apps R12.1.3 Rapid Cloning

Prerequisite Steps

1. If your target server holds at least one Oracle Apps R12.1.3 instance, you can skip for any OS patch or software requirement section. As the server is running a Oracle Apps instance, we can assume the server has all the

mandatory OS patch and required software. Else look into the metalink for platform specific requirements.

2. Apply Latest AD patch

Check whether AD patch version is atleast R12.AD.B.3. You can check that using following query.

SELECTpatch_levelFROMfnd_product_installationsWHEREpatch_levelLIKE'R12.AD%'

If it is below that level apply patch 9239089.

3. Apply the latest AutoConfig template patch

Update the Oracle Applications file system with the AutoConfig files by applying the latest AutoConfig Template patch (Patch 9386653 for 12.0.X customers and Patch 8919489 for 12.1.X customers) to all application tier nodes in the Applications instance. You can check whether this patch is already there or not in your system by the following sql.

SELECT * FROMad_applied_patchesWHEREpatch_name = '8919489'

4. Apply the latest Rapid Clone patches

For Release 12.1 apply following patches.

9171651:R12.OAM.B 12.1 RAPIDCLONE CONSOLIDATED FIXES JUL/2010

9833058:R12.OAM.B HOT CLONE FAILS WITH ORA-00201 DURING RECOVERY MANAGER 

12404574:R12.OAM.B ORACLE_HOME REGISTRATION DOES NOT HAPPEN WITH CENTRAL INVENTORY ON LOZ 

12598630:R12.OAM.B R12.1 ONE-OFF FOR S_DB_LISTENER BUG 12362010

5. Run AutoConfig on the application tiers

Follow the steps under section " RunAutoConfig on the Application Tiers " in My Oracle Support Knowledge Document 387859.1 to run AutoConfig on all application tier nodes.

6. Synchronize appsutil on the database tier nodes

Follow the steps under section "Copy AutoConfig to the RDBMS ORACLE_HOME" in My Oracle Support Knowledge Document 387859.1 to copy AutoConfig and Rapid Clone files to each database node via the admkappsutil.pl utility.

7. Run AutoConfig on the database tier

Follow the steps under section "Run AutoConfig on the Database Tier" in My Oracle Support Knowledge Document 387859.1 to run AutoConfig on the database tier nodes.

8. Maintain Snapshot Information

Log in to each application tier node as the APPLMGR user, and run "Maintain Snapshot Information" in AD Administration. To update the snapshot, please select the following options "Update Current View Snapshot" and "Update Complete APPL_TOP".

Cloning Steps

9. Prepare the source system

Execute the following commands to prepare the source system for cloning.

Prepare the source system database tier for cloning

Log on to the source system as the ORACLE user, and run the following commands.

$ cd [RDBMS ORACLE_HOME]/appsutil/scripts/[CONTEXT_NAME]

$ perl adpreclone.pl dbTier b.

Prepare the source system application tier for cloning

Log on to the source system as the APPLMGR user, and run the following commands on each node that contains an APPL_TOP:

$ cd [INST_TOP]/admin/scripts

$ perl adpreclone.pl appsTier

10. Shutdown the source system. Copy full directory "apps" and "db" from source system to target system. Use the following command for copy.

$ cp -RH

11. Configure the target system

Run the following commands to configure the target system. You will be prompted for specific target system values such as SID, paths, and ports.

a.Configure the target system database server

Log on to the target system as the ORACLE user and enter the following commands.

$ cd [RDBMS ORACLE_HOME]/appsutil/clone/bin

$ perl adcfgclone.pl dbTierb.Configure the target system application tier server nodes

Log on to the target system as the APPLMGR user and enter the following commands:

$ cd [COMMON_TOP]/clone/bin

$ perl adcfgclone.pl appsTier
