Changing IP and hostname in Application Server 10g

Because we moved our new OEM10gr2 server to the datacenter, the IP address and the hostname changed. When added to the datacenter I had to start all the services again, but first I had to change the opmn configuration. Instead of changing all the config files by hand, I noticed a shell script in the $OMS_HOME/chgip/scripts, called chgiphost.sh

This script changes all the config files and replaces the ip and hostname. It will ask you for the source and target ip/hostname...

Task : Run the chgiphost Command

Follow these steps for each middle-tier instance on your host. Be sure to complete the steps entirely for one middle-tier instance before you move on to the next.

1. Log in to the host as the user that installed the middle-tier instance.

2. Ensure your ORACLE_HOME environment variable is set to the middle-tier Oracle home.

3. Run the following commands in the middle-tier Oracle home:

   cd ORACLE_HOME\chgip\scripts chgiphost.bat -mid

   ORACLE_HOME\opmn\bin\opmnctl stopall
   ORACLE_HOME\opmn\bin\opmnctl startall
