EBS rac clone

[satish]

Dear Erman,

We are following Cloning Oracle E-Business Suite Release 12 RAC-Enabled Systems with Rapid Clone (Doc ID 559518.1) to perform clone of our existing UAT from PROD instance.

Both are similar configuration with 2 node rac with version 12.1.0.2

Our requirement seems matches with Section 8: Advanced Cloning Scenarios
8.1 Cloning the Database Separately

Our concern is,the uat is already existing and we have the context file in place.In this case,can we skip below steps and proceed running adcfgclone dbtechstack with referring the existing context file?

5.1.2 Create pairsfile.txt File for Primary Node
Create a [NEW_ORACLE_HOME]/appsutils/clone/pairsfile.txt text file with contents as shown below:
s_undo_tablespace=[UNDOTBS1 for Initial Node]
  s_dbClusterInst=[Total number of Instances in a cluster e.g. 2]
s_db_oh=[Location of new ORACLE_HOME]

5.1.3 Create Context File for Primary Node
Execute the following command to create a new context file, providing carefully determined answers to the prompts.
Navigate to [NEW_ORACLE_HOME]/appsutil/clone/bin and run the adclonectx.pl utility with the following parameters:
perl adclonectx.pl \
  contextfile=[PATH to OLD Source RAC contextfile.xml] \
  template=[NEW ORACLE_HOME]/appsutil/template/adxdbctx.tmp \
  pairsfile=[NEW ORACLE_HOME]/appsutil/clone/pairsfile.txt \
  initialnode


Thank You

If nothing is changing in the configuration and if your target context file there in place and it is correct , then yes. You should be able to skip those context file creation steps.

Hi Erman,

I will give a try.
There is no reference about cloning grid home in this standard document.
It is only talking about rdbms home like,tar the oracle home from source..copy to target...untar it in target.
What about grid home?is it not required to clone grid home?

Because we will be testing applying latest security patches in UAT and then we will move them to PROD

Thank You

No need. If your PROD and TEST environment GRID homes are sync in terms of patchsets and versions, then no need.

Dear erman,

Thank you.

We have tested applying psu patch in Test environment and it is not applied in prod.We have also done post steps for that psu patch.

In this case,can we ignore grid home clone?
I think versions will be different here as we applied psu in test but not in prod.

Thank you

It is your choice. In this case, EBS will work without refreshing the GRID.
That is, you can ignore installing a new GRID for your clone environment, or cloning the GRID
for your clone environment. But again, this is your choice and something that you need to decide.

Dear erman,

Any reference for cloning grid home in ebs?

Thank you

[ErmanArslansOracleBlog]

I dont think that there is a specific reference for EBS. 

It s a pure Grid/RAC work.
