IP change makes the system down.

Dear All,

My restoration activity was successful. But changing the IP was failed.

Actually the scenario was management wants out dev system to be refreshed with production data, But they also need the current development system for one month for some reference. So the plan was to refresh the production database in existing dev and to keep a copy og old dev in a seperate system for some time.

The restoration of backup was successfull. But copy og development in another system with different IP was not starting. Database was getting started but SAP was not getting started. Its not finding the profile. I've updated the IP in /etc/hosts file, listener.ora file, tnsnames.orafile. I checked the SAP instance and start instance profile and it don't have any IP. I refered Note 403708. But didn't help.

I don't know what needs to be done to start that instance. If I need to change the hostname also to start this instance. If I've to change hostname what things need to be done.

Please help.

Thanks and Regards,

Santhosh Kumar.
