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.
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.
The complete steps to deploy VCS with Oracle database as a highly available service are documented here:
The above files contain COMPLETE instructions on installing and configuring VCS on RHEL. Now RHEL costs money and the free trial is only limited to 30 days and is also kinda hard to actually get. So, I have created another document on installing VCS on CentOS 6.5.
NOTE: This document is meant to supplement the above documents. It is available here:
For converting CentOS7.1 to RHEL7.1, please change CentOS7.1 /etc/redhat-release file to reflect this:
Red Hat Enterprise Linux Server release 7.1 (Maipo)
NOTE if you are using any other versions of CentOS7 then you might have to change accordingly, example 7.2 Red Hat Enterprise Linux Server release 7.2 (Maipo)
I encourage you to contact me at firstname.lastname@example.org with any questions that you may have. Like I said VCS CAN BE LEARNED AT HOME. I WILL TRY TO HELP YOU.
