SAS Enterprise Miner Mid-tier Server Clustering

SAS Enterprise Miner 14.2 supports the SAS 9.4 Intelligence Platform Mid-tier Server Clustering. The detailed architecture and benefits of this web application cluster is documented in the SAS 9.4 Intelligence Platform: Middle-Tier Administration Guide.

Installing the SAS Enterprise Miner Mid-tier Server as a cluster is not much different from installing it in the standard client/server deployment. The SAS Deployment Wizard installation prompts are unaffected by server clustering.

For example, in the three-machine SAS Enterprise Miner deployment example in this book, you can add an additional SAS Enterprise Miner Mid-tier node to form a two-node SAS Enterprise Miner Mid-tier cluster. To do so, run setup.exe from the original software depot and proceed as if you are completing a standard installation. When you get to the Select Deployment Step and Products to Install window, select Step 3: Middle Tier Node (Optional).

When prompted for the Metadata Server, you must specify the same metadata server host name that you specified in the first installation stage. Ensure that all SAS Development Agents are running in all server nodes that are used in the server cluster. This enables the SAS Deployment Wizard to automatically integrate each new machine into the existing deployment as a server cluster member.

You must enter the same passwords specified in the previous installations.
