I have an issue about Citrix making connection to Oracle. The Citrix is host on a Win2003 server. When the user tries to login Citrix, it flows TNS error (TNS error: no listener). But I can use SQL developer (from another pc) connect to the same database without error.
If I use tnsping (on Win2003 server) to the db server, it maps to the wrong port. I check the tnsnames.ora which has the correct port details. Anyone can help with this?
