Suresh,
You're definitely on the right track -- however, you'll want to put the updated property into the "Custom Properties" section of your glog.properties file, so that it will override the default setting in glog.common.properties. You always want to make your changes in glog.properties, rather than the other files, as they will often get replaced during patches, upgrades, etc.
So in glog.properties, you'd have one of the following (depending on your OTM instance):
Code:
p_rep_userid=hide_pass_key_rep_server1
or
Code:
p_rep_userid=hide_pass_key_rep_server2
Also - make sure the web and app servers each have the same respective property defined.
Thanks,
Chris
