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

Shell Programming and Scripting
1

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.
