VERITAS A QUICK AND DIRTY GUIDE

Veritas is a trademark of Symantec corp and/or of Veritas. RHEL is a trademark of Red Hat. Oracle is a trademark of Oracle. There are other various trademarks no attempt is made to infringe. Apology as necessary is made in advance.

This guide may prepare you to work with the daily routine tasks of veritas cluster server on RHEL.
This guide may be useful for the following tasks:
1)Understand the meaning of clustering and High Availibility.
2)Understand the components of Veritas Cluster server.
3)Installing Veritas Cluster Server
4)Installing Oracle Database as a highly available service (this means it will run on one node if another node fails).
5)Basic maintenance of a Veritas Cluster.
6)Troubleshooting
7)Interview questions.

This guide is best followed by actually doing all the steps presented herein. I am using an i7 PC with windows operating system(you may use RHEL), 8GB of Ram(this is the very least recommended) and about 350GB of disk space. A network interface is required. An internet connection is required. Free accounts at Symantec(for downloading the trial version of Veritas Cluster Server SFHA Storage Foundation High Availibility) and at Oracle(trial edition of Oracle Database Enterprise version) are essential.

In Virtualbox(free virtualization technology that works on both windows and on Linux) I am giving 2048MB to both VM's and 1024MB to the virtualised storage(openfiler). I am designating one cpu for all three. So, for an 8GB physical host this leaves 8-2-2-1=3GB for the underlying operating system. And, leaves, 4-1(openfiler)-1(node1 of the cluster)-1(node2 of the cluster)=1 core(cpu) for the base system which hosts the virtual cluster environment, of the 4core cpu i7 processor.
