In my test environment I have a primary CA 11.1.6 server with Gateway, application tier, and CM installed.  I've also have a second CA 11.1.6 server with application tier, and CM installed. This is the standby CM server.  I've set up the URLs on both servers to list out the primary server first and the standby as second.  
My question to you is - what do I need to do for accessing the second application tier? Per IBM doc#721319 I should setup server farms in IIS but is that all? What steps are needed to configure the 2nd application server so that it is available for processing requests?

As you can tell this is my first time with a distributed system. All prior setups have been a single server instance. Thanks in advance for your help and advice.

Hi Scott,
I'm assuming that you have updated the "Configuration group" settings within each app servers config file? After that it should just be a case of restarting the services. You should see when you start the second server up that it will detect that a content manager is already running. Once both are then up you should be able to see both dispatchers via the admin console and that they are both available.

Hey Scott,
Once you fire up additional dispatchers in your environment, they should automatically become registered in your content store, and as Jonathan mentions, you will then see the second dispatcher in the admin console, where you can configure and tune the individual services on each dispatcher.  Typically I would recommend having a single, dedicated machine just for your primary content manager, as this type of dedicated resourcing tends to have the greatest performance profile, but every environment is unique.  Either way, distributing your load by scaling out this way should have positive impact on your environment's throughput, but make sure you are maximizing resources!

Dear @Scott Taylor,

In addition to information provided in aforesaid comments...

Since you mentioned "test" environment, I am assuming you are setting up a temporary environment for your usage.
You can access the Cognos application seamlessly via either of the 2 dispatcher URIs in your scenario.
App tier should internally distribute & process the requests amongst available dispatchers.

Server Farm/IIS will help you to load balance the requests amongst underlying 2 application (dispatcher) tier components.

Hope this clarifies.
