Domain Administration Server HA

Greetings,

I'm in the process of setting up a Appserver cluster, with four nodes.

Originally I planned to install domain administration server on one machine, then install nodeagents on all four machines.

I was going to create a cluster and add the node agents.

However, what I have run into is, if I lose the machine that is the domain adminstration server, what will I do?

Can I install domain adminstration servers on multiple machines and manage the same cluster configuration? do I just need to mirror the "domains" directory to another server, and if that macine fails I can start that domain on another machine?

I guess my questions would be what the best practices are for deploying applications server cluster and how to maintain high availability on the administration servers.

I'm using Version 8 Enterprise Addistion btw.

Thanks in advance!

Jeremy

I am in the same place as Jeremy and would like an answer to his question.

Also regarding recreating the the DAS:

Lets say you set up a cluser with 2 server instances across 2 machines with the Admin (DAS) server on the first nodeagent/server instance machine. Can you use the second nodeagent/server instance machine as the backup machine to recreate the DAS? If so, any special instructions? I certainly do not want to have to involve a 3rd machine.
