How To Change the Hostname In E-Business Suite R12.2.5

[karthikmca.bhc]

Hi Erman,

Please guide me on how to change/update new hostname and IP on the existing 12.2.5 ebs instance.

Existing:
----------
EBS application version: 12.2.5
Database version : 12.1.0.2
Operating system: oracle Linux server 7.4 64-bit
Hostname: xxxx.abc.com
IP address: 192.168.10.20

Change requirement:
------------------------
EBS application version: 12.2.5
Database version : 12.1.0.2
Operating system: oracle Linux server 7.4 64-bit
Hostname: yyyy.abc.com
IP address: 192.168.30.40


At OS level the hostname and IP address has been changed and I hope the databases and application startup will fail with old hostname and IP.

What are the changed I must to in order to make my EBS 12.2.5 functioning as normal?

Thanks.

Current, there is no documented(MOS note ) way for doing this.
So, if you are changing only the application node's hostname, then you need to execute adcfgclone.pl. (like you are doing a standard cloning process)

If you are going to change the hostname of your db node, there are other things to do ..

Tell me if this answer satisfies you.

For further info, give me more details about this hostname/ip change.

Hi,
Using the adcfgclone.pl the later is not working.

Actually I want to change the IP address and hostname of the EBS but not working. Do you have any document on how we can change both. The database and application server are two servers.

Thanks

Hi,

Please follow -> How to change hostname for E-Business Suite Release 12 on single node (Doc ID 1277556.1)

This node is for single node, but the logic is the same.

take the actions related with DB in your DB node , and take the actions related with APPS in your Apps node.

You can also use the following method (If I were you; I would use this method )  ->

Shutdown the apps tier
Shutdown the db tier & listener
Change hostname on your apps node OS
Change hostname on your db node OS
startup the database
sqlplus "/as sysdba" -> "exec fnd_conc_clone.setup_clean"
manually edit the listener.ora on your db tier (with the new hostname) and start the listener.
recreate the db tier context file (with the hostname)
run autoconfig on db tier
set the newly generated db tier env (generated by autoconfig)
restart the database and the listener
run adcfgclone.pl on your apps tier
start apps services.
