Hi,

Just replicate the fs from PROD to DR (using same mount points and directory structure in the DR) and do the post configuration when needed.. You can also use virtual hostnames and Load Balancer host names if you don't want to do anything in the DR, any configuration during a switchover a failover.

Thanks Erman for your Suggestion . I shall check with the Unix team if they can replicate for me . However we just need a DR server incase of a failure .

Could you please help me where i can look for the configuration files .

Hi Erman ,
I have copied the WT & Middleware folders from the primary to secondary as per your recommendation .

Could you please help me which configuration files do i need to check and change .

If you have a virtual ip/hostname, then you don't need to manage any of those things.

On the other hand; if you have a different physical hostname on the target and if you don't have a virtual host config, then you need to change the relevant config files during the switch over or failover operations.. The configuration that I m talking about here is based on a subset of the tasks that you do during cloning.. (you will modify files like httpd.conf etc..)

Thanks Erman ,
Yes its a separate physical host. Do i need to run any cloning script ?
can you please let me know which files i need to configure other then httd.conf .

Thanks for looking .

You got to change the listen address in those conf files.. But if you have a virtual host config then you don't need to do anyting as I already mention..
