We usually have cost considerations when deciding if we also want
QC/Dev environments to be clustered besides the Prod env, esp in a
company where IT department is outsourced. We are running
Solaris/Oracle/Veritas FS, VXVM, DMP, VCS.
What other reason(s) for clustering in non-prod env, apart the reason
of being able to test patches/applications in a QC/Dev env before
applying it to Prod? I would like to hear from your experiences,
thoughts. Thank you.

I think the aspect you point out, is sometimes very important. The
handling of Software/Updates/Applications/Analysis could be very
different from an unclustered Environment, e.g. crontab and
Logfiles-Handling and analysis. But despite of that, we often have
developers who are very nervous, when a machine crashes shortly before
deadline ;-(. But nevertheless the product ist often to expensive to by
also licences for Dev/QS.

I can't speak for Symantec but I'm pretty sure they'll let you run
demo keys in dev/qa environments year round.

So this might help on the cost front. Unless of course the extra
hardware is the mitigating factor.

not true, the keys are valid for 3month and you can prolonging for
further three month. You can use news keys, but thats not legal.
Or has Symantec changed the handling with demo-keys?

If cost is such an important factor then maybe you should consider
Sun Cluster which is free now?

Sun Cluster would be a good idea. They don't have to pay for support in the dev/qa environments.
However, for the production clusters that require commercial support contracts at my company,
Sun Cluster was as expensive as VCS.

Is sun cluster different from VCS? I thought sun might be using the
clustering technology from Veritas!!

Thanks

Nope. Sun Cluster is an entirely different bit of software, and has some
fundamentally different ways of doing things.

Have you check JES support (for example only HA group)? Of course
if you qualify (company with over 100 employees).
IIRC it's 70$ x # of employess per year and you have got
support for as many Sun Clusters as you want.
