Thanks for the reply it will help me a lot.
I am actually using AIX 6.1 with Oracle 11g. Running a Banking Application (I-Flex).
I am sill in installation phase I can do as much R&D as i can, before going for production.

As far as i know if i use DIO it will not use filesystem caching and oracle has its own caching.
If both oracle caching and FS caching are used the performance will degrate..
So i am thinking of using DIO & AIO . what do u think.
you are absolutely correct there is no particular way for tuning IOs we have to test it and do according to the result.
I just want some suggestion coz planning of one mind can be incorrect also.

NAME
Apache::Session::Oracle - An implementation of Apache::Session SYNOPSIS
use Apache::Session::Oracle; #if you want Apache::Session to open new DB handles: tie %hash, 'Apache::Session::Oracle', $id, { DataSource => 'dbi:Oracle:sessions', UserName => $db_user, Password => $db_pass, Commit => 1 }; #or, if your handles are already opened: tie %hash, 'Apache::Session::Oracle', $id, { Handle => $dbh, Commit => 1 }; DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the documentation for Apache::Session::Store::Oracle for more details. USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order to make you think about this problem. This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default maximum is 8 KB. AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>. SEE ALSO
