Actually we have to add one more citrix server to our environment. Can anyone suggest how to set up the TNS_admin environment variable in citrix server.
If you have a citrix/acquisition server configured already, just copy it from an existing system to the new citrix server.
Search under the Empower\Oracle directory, for *.ora files. Ours is located in \Empower\Oracle\Oracle12cClient\network\admin\
Copy to the new server as MJS suggested.
