I was able to connect to oracle 11g R2 database from Oracle Sql developer in the Server until it did not connect to the network.
Once the server has been placed in the network, provided remote desktop connection to access this server.
When I'm trying to connect to 11g database from Sql developer, getting "IO Error: Network adapter could not establish the connection."
I have changed the host name in tnsnames.ora file and listener.ora files and updated in Sql developer connection but no use.
If anybody know or anyone faced same issue please help me on this one.
Thanks in advance,
Raj.
