R12 | Clone response file | adcfgclone automation

Hi guys

If you are familiar with R12 cloning, the entire process requires loads of input from a DBA before the cloning really starts kicking in. Now, there could be hundreds of reasons for the cloning process to fail and keeping on entering the responses for the cloning prompts are NOT at all fun, minimum for me.

So I started searching for “R12 clone response file” & google landed me in this post

Excellent way Hussein Sawwan-Oracle has explained how to create the response files for both db, apps tier.

 

clone

First of all, context file to response file creation has a validation flag, which confirms the responses provided are valid throughout the response collection. This validate has a downside with the port pool selection. You will receive a port is not free error while the Oracle application is online, for which a system reboot is most recommended (rather than selecting “No” for the validation process”) after graceful shutdown of both application and database tiers.

I’m using .bash_profile files to source the environment for both my Oracle (oraprod) and Application Manager (applprod) accounts, hence I was able to shorten the efforts like following

As Oracle user (oraprod)

# cd $ORACLE_HOME/appsutil/clone/bin
# perl adclonectx.pl contextfile=$CONTEXT_FILE outfile=/u02/db.xml

Provided the responses and the db.xml was successfully created under /u02 and the context file creation log was created under /u02/log folder.

Please make sure you do “echo $CONTEXT_FILE” to check whether you $CONTEXT_FILE returns a meaningful file name!

As Application Manager user (applprod)

# cd $COMMON_TOP/clone/bin
# perl adclonectx.pl contextfile=$CONTEXT_FILE outfile=/u02/appl.xml

Now you should able to run the cloning processes using the newly cloned context files, for example

# perl adcfgclone.pl dbTier /u02/db.xml
# perl adcfgclone.pl appsTier /u02/appl.xml

That’s all folks, it works like a charm & you are NOT anymore typing in whole those lengthy paths and other variables :)
