I'm baffled with a problem in connecting a client to a server(remote connection).
The entries in tnsnames.ora on the server side are working fine(when connected from the server).I use the same configuration on my client side,but it doesn't work.
TNSPING for the connect strings are OK.
I get a couple of errors from SQLPLUS,like:
1)ORA-12545 : Connect failed because of target host or object does not exist
2)Oracle not available
3)Shared realm does not exist.
Thanks for your inputs...!!!
