Hi,

Thanks for your replies, appreciate it !!

I have two Solaris 11 VMs with Oracle Clusterware running on VBox, both of them with 4GiB RAM, problem is they get slower and slower and then all of a suden one of them gets crashed, it happens so frequently that I just cannot work, increasing RAM is out of question, previously I was running the same setup on Oracle Linux 5 and I was able to tweak the memory using the above script and never got a crash.

I need to find a way to tune the memory in solaris so the VMs can stay up and I can do the work.

Here are the mem stats from one of the server, this will give you an idea as to whats happening and you may be able to suggest me a way to tune them.

Just to let you know I am very new in Solaris so every bit of information will be very helpful to get this problem resolved.

echo ::memstat | mdb -k
Code:
Page Summary                Pages                MB  %Tot
------------     ----------------  ----------------  ----
Kernel                     202104               789   19%
ZFS File Data                9039                35    1%
Anon                       750232              2930   72%
Exec and libs               34059               133    3%
Page cache                  36889               144    4%
Free (cachelist)             6119                23    1%
Free (freelist)             10021                39    1%
Total                     1048463              4095

Please have a look at above stats and suggest me what to do.

Thank you very much for your assistance !

Regards
Terry

Apache::Session::Oracle(3pm)				User Contributed Perl Documentation			      Apache::Session::Oracle(3pm)

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
Apache::Session::File, Apache::Session::Flex, Apache::Session::DB_File, Apache::Session::Postgres, Apache::Session perl v5.10.1 2010-10-18 Apache::Session::Oracle(3pm)
