Installing Oracle Application with shared File system

This activity I carried out in one of my Project for setting up a production. I am putting exact steps.

Installation Specifications :

Number of Nodes : 3
Node1 : Database
Node2 : Admin & Concurrent server (NFS Share)
Node3 : Forms $ web (NFS mount)

Operating System : Solaris 10

Application Version : 11.5.10.2

Steps :


1. create nfs share on node2 say /prodxyz. share /prodxyz.
2. create same directory /prodxyz in node3 also. Be sure when you do pwd in node2 or node3 this should exact same directory structure.
3. share (by nfs) /prodxyz in node2.
4. mount node2 /prodxyz on node3 /prodxyz.
5. check /prodxyz should have sufficient space for installation.

6. create database user in node1 say oraprod with home directory /prodxyz/oraprod. Note that there is no nfs mount from node2 on this node1. we are just following uniformity.

7. create apps user in node2 and node3. take care that they should have same userid and group(generally dba) id. Also the oraprod should also have same group and group id as apps user. say apps user is appsprod.

8. Home directory of appsprod is /prodxyz/appsprod (which is shared).

9. Now begin the installation from database end (node1)

10. select multi node installation. It will ask you at some stage for node information. on that stage click on details tab. select node2 "INSTALL" and for node3 "share existing".

11. rest follow the screen as normal installation.

12. after installation on node1. begin installation on node2 sourcing the context file from node1.

13. after installation on node2 begin on node3 sourcing the same context file. Note that begin installation at node3 with appsprod user. otherwise installation will error out.

now leave rest on installer.

wow you have implemented applications shared file system !!
