High Availability and Fail Over in IIS 8.5

mavrick21 · Post by **mavrick21** » Fri Oct 19, 2012 6:42 pm

Hello,

We've license for IIS 8.5 Server edition. Does IIS 8.5 have High Availability and Fail Over features? If yes then how do we go about enabling it?

Also wondering if IIS 8.5 engine (with Server license) can be installed on more than one RHEL 5 server and make it use more CPUs? I know it's possible with Parallel jobs but wasn't sure about Server jobs.

Thanks

There's information on HA over in the IBM Information Center, for example this topic, specifically Planning Step 3 and the "High availability configurations" section.

Craig,

Thanks for your reply.

From this acticle I understand a bit about HA. But would this help to run DS jobs without interruption in case primary server failed? If it doesn't then could you please give me a scenario where HA configuration could be useful while running DS jobs?

Thanks

Sorry but I'm not current on their HA offerings. I've done something similar in the long past on a Compaq Tru64 clustered system with 7.5 but there was nothing 'transparent' in the failover we were able to handle... and the new 8.x architecture will complicate that. Automated, sure, fail over, yes but without interruption? Not so much.

Best to contact your reseller or IBM directly for questions like that, I would think.

Craig is correct. I have performed HA installs for clients, there is nothing seamless about the failover. Some people have automated the actual failover piece based upon monitoring scripts, however all jobs running will stop and will have to be started on the failover server.
