Priyank,
You can use a Webcache frontend to provide software only load balancing
and session persistence, and this is certified, but wont give you high
availability (If the host where the webcache is goes down, the system becomes
unaccessible).
See note 306653.1
Regards,
Luis

Hi Atul,
Thanks for the response.
I understand that this is not certified, but given the situation, I need to
take this up as a challenge.
I have gone down to the OS level to get a resolution to this. One option is
using Heartbeat package shipped for Linux.
I'm also investigating using the IPVS service distributed with the RHEL to get
around the issue of maintaining session data such as cookie to ensure that the
client always connects to the same server.
Will keep you all posted on any developments. Any help on this subject is much
solicited.
Thanks,
Priyank.

Priyank,
Software load balancer is not supported/certified in front of Oracle Apps
11i/R12 as it can't maintain session persistence (It is requirement in apps
that request from one client always connect to same server till user session
logout )
