The current environment is not Oracle RAC and has multiple SID running into it and each SID has ora<sid> to log on and manage the specific DB and BRTools. No need to set environment everytime when log one to specific sid user to manage DB
However, using one Oracle User for all SID, would you be setting environment variable manually everytime when you log on to Oracle user?
I am still not clear on this. This would be real challenge for us with 7 sid in development environment.
