Thanks for reply
I have changed the sqlnet.ora file inbound connection timeout but getting the same error So as per my observations to check the connectivity from server through putty or fire a command are also very slow So it is network fluctuation .
I have very much in dba but my observations is this network connectivity problem or it my firewall connection time out to close the connection after certain time.
Thanks

12560/12537 means we could not successfully talk to the the listener
which could be:
- listener not started
- sqlnet.ora config error
- firewall issues
etc
