How to solve TCP connection timeout (not in ssh)?

HI

We have some Red Hat Linux Sevres which is having TCP connection timeout, not SSH connection, as an example oracle connection connected from TOD.

SSH i managed to add keepalive and it's working fine

Linux has built-in support for TCP keepalive. You need procfs and sysctl support to be able to configure the kernel parameters at runtime.

The procedures involving TCP keepalive use three user-driven variables:

tcp_keepalive_time

the interval between the last data packet sent (simple ACKs are not considered data) and the first keepalive probe; after the connection is marked to need keepalive, this counter is not used any further

tcp_keepalive_intvl

the interval between subsequential keepalive probes, regardless of what the connection has exchanged in the meantime

tcp_keepalive_probes

the number of unacknowledged probes to send before considering the connection dead and notifying the application layer
