shared oracle apps from node 1 & 2

Shared Oracle Apps — Mon, 25 May 2009 04:34:17 GMT

I am using oracle RAC on HP-UX 11.23 EOE. I want to share application from SAN to both HP-UX Servers i.e node 1 & 2. Is there any possibility on to share the application from san without using CFS & Service guard or is there any third party software to solve the problem ?

Regards,
Afroz

Hi,

one way is using nfs. But in this case you must consider some parameters like performance, etc..

There is performance issue with NFS. I am already oracle RAC on HP-UX 11.23 EOE without using CFS/Service Guard.
Now I want to shift my application on SAN (RAW) and want to share it from both HP UX servers witout using NFS.
Is there any solution?

hi,

are you using LVM?
you can activate the VG in exclusive mode (r/w) on node1 and in read-only mode on node2. For read-write access to both nodes you must use NFS.

Shalom,

All you need for a RAC shared application is RAC. You don't need SG unless RAC requires it, which newer versions do not require.

CFS is a high availability file system, but RAC can mount shared storage with the volume group in shared mode without need of any products.

Oracle has OCFS2 file system for RAC Linux. They might have an equivalent for HP-UX as well.
