Changing the ip address on Oracle server.

Recently my system's ip got changed and the after effect is when i tried to up my applications, it was unable to connect to the oracle database.

If your system's ip address have been changed then you got to test whether your oracle db is properly starting up or not and whether your applications which connect to Oracle are able to connect to oracle.
If you got a problem then you got to change the ip address of Oracle.

For changing the ip address on the oracle server, we need to change the following 2 files.
1. tnsnames.ora
2. listener.ora

You can find both the files in "oracle\product\10.2.0\db_1\NETWORK\ADMIN" path.
Replace the old ip address to new one.
