It is really easy to configure HA cluster in Red Hat.   It is very well documented too.  Are you still open to keep Red Hat, I can give you further instructions

No, absolutely not.  However, they will both have to be installed with same Red Hat cluster suite.

Working:

It keeps a heart beat-- checks periodically if the service is up, and if it is not, it would bring up on the other machine.  It is hardware independent.

Thanks for the reply, As of now iam having rhel5 basic subscription is it possible to purchase redhat cluster suite sperately instead of purchasing RHELAP. Please suggest as i have to use it for the production server for this iam afraid going for heart beat but if this stable and recommended then will go for this please suggest. Thanks.

Here is some documentation

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Cluster_Suite_Overview/index.html

Red Hat systems are pretty stable.  You can go for Veritas if you like but that would be more expensive.

Heart beat is the process by which servers keep track of each other to see if the service is up and if it is not, then bring it up on another machine.  It is the basic thing in every HA cluster.

Sir, Thank you very much. finally one information that is rhel5 basic subscription does not support cluster only RHEL5 AP was supported now RHEL5 basic is no more . my doubt is RHEL6 standard subscription comes with High Availablity cluster enabled for the standard subscription as RHEL6 advanced platform is expensive is standard subscription suppports then it is really great i can go for RHEL6 standard subscription.

Here is a link, you should be able to download for free, just for TRIAL
http://www.redhat.com/rhel/add-ons/high_availability.html

Try it, test it and see if it is useful for you and satisfies your needs.


In the same link you can see their pricing but if you need more details, I suggest you should email Red hat and get the correct information.
