Routing to multiple cells
Intelligent Management for Web Servers routes HTTP requests to multiple WebSphere Application Server cells without regeneration of the plug-in configuration file after environment changes. When servers, cluster members, applications, or virtual hosts are added, removed, started, stopped, or modified, the up-to-date information is dynamically delivered to the WebSphere plug-in.
To use routing rules to route to multiple cells, each cell must have a different cell name. Use the procedure at Configuring Intelligent Management for web servers to set up routing from the Intelligent Management enabled WebSphere plug-in to applications in multiple cells. There is no change in the procedure to configure multi-cell routing, however, you now have the capability to install the same application in multiple cells.
- If you deploy the same application to two different clusters, you can use routing rules to direct requests from a particular set of client IP addresses to one of the clusters and the rest of the requests to the other cluster.
- If you deploy the same application in multiple cells, you can use routing rules to send the requests only to the first cell, unless no servers are available in the first cell, then send requests to servers in the second cell.
