Best way to point/update a file during PROD and BCP failover.
Hi All,

In UNIX servers we are switching from DR to PROD. After switching to DR
we need to update some configuration files which contains the server names.

Ex - If we switch to BCP we need to update BCP server name.
If we switch back to PROD we need to update PROD server name.

I have below options for performing above task.
  1. Create a link to PROD and BCP separately and just invoke the link.
  2. Update the config file with the server name.

May I know which option is better.

Kindly advise me for any better option

Question is a bit vague...

If you are referring to configuration files regarding your application, best approach would be to use one master configuration file which is relinked during DR and back.

So i guess, option one.

You can also use exported variable in your users $HOME folder .profile
For instance, you have a variable in your .profile export DR=1 and every other code ran on that machine references to it...

if DR=1 we are on DR will use these configuration files, else if DR=0 we are on primary site using other set of configuration.
Change would be only one number(DR 1 or 0), sourcing .profile after, and application start.

Regards
Peasant.
