Another possibility is to use the loadparm with a system config file name in it which is useful if you have PPRC'd dasd and have switched the primaries and secondaries and perhaps they aren't back in sync yet and duplicate volumes would cause issues. LOADPARM of "FNSITE1" will use a system config file name of SITE1 CONFIG.

That may be all you really need. One possibility, procedural instead of program logic, would be to use the SALIPL screen to specify a different CONFIG file when you are at the DR site.
