(Figure 5-20).

4. Enter the name of the server group you want this dispatcher to be a part of, and click OK.
The dispatcher will now be able to process queries that are routed to the server group.
The process of removing a dispatcher from the server group is the reverse of the procedure
that is described.
Clearing the server group name field in the dispatcher configuration prevents queries for the
cubes in that server group from being routed to it. The cube or the dispatcher itself can then
be administered or taken down for maintenance.

Routing” topic in the Cognos Business Intelligence Administration and Security Guide in the

5.6 Scheduling a refresh of the cache
Administration commands often need to be run at predefined times and intervals. For
example, the data source from which the dynamic cube is built might be continuously
updated, so the cube member and data caches must be updated also.
Note: Propagation of information about dispatcher membership in server groups to all
affected dispatchers is not instantaneous. You might have to wait up to a minute for the
changes to take effect.
