Do we need to just add an entry to the listener.ora in Oracle DB to get the connection working? Is that all what is required?
or
I have found a metalink note: How to Setup DG4MSQL (Oracle Database Gateway for MS SQL Server) 64bit Unix OS (Linux, Solaris, AIX,HP-UX) [ID 562509.1]
Do we need to set it up in Oracle DB first?
Thanks,
