@All, Thanks for prompt response.
We have same problem across all IS irrespective of connecting to Exadata, Oracle, SQL server with different versions and Oracle support could not give any solution. I suspect it is in network. Yes I have plan to increase timeout which will overcome such errors however still it is like suppressing errors
Please can you suggest what is the ideal parameter setting for connection pool; specially what is for block timeout and expiry timeout.
Regards,
Gautam
