My RAC project with Openfiler, part I – Openfiler

My current job doesn’t offer me at the moment the opportunity to play with RAC or other stuff, so I decided to build my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) :

  • 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra and database.
  • 1 VM as my own storage, based on Openfiler 2.3 (free) and ASM as storage manager.

Powered by rPath Linux, Openfiler is a free browser-based network storage management utility that delivers file-based Network Attached Storage (NAS) and block-based Storage Area Networking (SAN) in a single framework. Openfiler supports CIFS, NFS, HTTP/DAV, FTP, however, we will only be making use of its iSCSI capabilities to implement an inexpensive SAN for the shared storage components required by Oracle RAC 11g. A 500GB internal hard drive will be connected to the network storage server (sometimes referred to in this article as the Openfiler server) through an internal embedded SATA II controller. The Openfiler server will be configured to use this disk for iSCSI based storage and will be used in our Oracle RAC 11g configuration to store the shared files required by Oracle Clusterware as well as all Oracle ASM volumes.

My goal: just a little bit hands-on experience with Openfiler, and do some testing with RAC 11gr2, and especially 11.2.0.2. Maybe it’s helpful for somebody else, so I’ll post my experiences. Steps I’m gonna perform.

–          The first post (this post) :

1.       Planning my installation
2.       Create a VM with OpenFiler
3.       Configure Openfiler

–          The second post:

4.       Create a VM as node rac1 and configure ASM
5.       Create a VM as node rac2
6.       Install Oracle RAC Infrastructure
 
7.       Install Oracle RAC Database software

8.       Install Oracle RAC Database

Script for setting up ssh on RAC-nodes

Finished a RAC-course a while ago with instructor Harald van Breederode. Noticed that he used a script for setting up ssh on the nodes. Short, powerful. Used it myself with user grid and oracle while installing 11g RAC.

First of all, one file should exist on forehand: $HOME:nodeinfo. Should look like this, one noder per line:

rac1
rac2

Then the file ssh_setup.sh:
