No, there was no system environment variable. That would have also been displayed using the SET command. Also, no Oracle_home was set. -----Original Message----- From: Patterson, Joel [mailto:Joel.Patterson@xxxxxxxxxxx] Sent: Wednesday, August 22, 2012 6:21 AM To: Thomas.Mercadante@xxxxxxxxxxxx; Storey, Robert (DCSO); oracle-l@xxxxxxxxxxxxx Subject: RE: Tnsnames mystery Yes, it sounds like a 'system' environment variable.

Did it have the network drive in the path? ORACLE_HOME does not need to be set. TNS_ADMIN is an environmental variable.

Going to look to see if it is set someone where else.

It is possible that there is a setting there, and if so, it will not show up when you use SET.
