MICROSTRATEGY WEB CLUSTERING

Does MicroStrategy Web support clustering via Cisco Local Router or any other third-party clustering software?

MicroStrategy Web relies on third-party web-clustering software to provide clustering functionality. MicroStrategy Web is designed to be stateless so that each individual MicroStrategy Web node can function without the knowledge of the existence of other nodes. Therefore, any third-party software used to cluster web servers can be used.

What information is shared by the application across MicroStrategy Web nodes?

MicroStrategy Web is designed to be as stateless as possible. Therefore, no information is shared by the MicroStrategy Web application across cluster nodes. All state information for running jobs is pushed to the client browser.

When a report is submitted by a MicroStrategy Web user, the user will receive a wait page in the client browser. This wait page will poll the MicroStrategy Web Server periodically for the status of the report. This polling is performed as new http requests. This http request will contain all state information, including encrypted login information and MicroStrategy Intelligence Server connection information.

Is MicroStrategy Web "cluster-aware"?

The MicroStrategy Web application is designed so that each MicroStrategy Web cluster node does not need to know that it is a member of a cluster. MicroStrategy Web is designed to be stateless, so that each client http request can be processed individually without having to persist information within the MicroStrategy Web application. Therefore, third-party Web-server clustering software can be used to cluster together multiple web servers running MicroStrategy Web.

Should MicroStrategy Web be specifically configured to access a MicroStrategy Intelligence Server cluster?

No. When the administrator configures MicroStrategy Web to access a particular MicroStrategy Intelligence Server, the MicroStrategy Web application will automatically detect that the MicroStrategy Intelligence Server is a member of a cluster. Once this detection is made, MicroStrategy Web will automatically add all the other members of the same cluster into the pool of available MicroStrategy Intelligence Servers.
