Controlling resources for index updates

You can set the advanced configuration parameter, CSN.Indexing.Level, to control the CPU and memory use of an indexing job and, thereby, manage the impact that the indexing job has on available resources. A value of "high" indicates that the server is dedicated to IBM® Cognos® searching and indexing, whereas a value of "low" indicates that the server runs indexing jobs in the background.

Note, as a general guideline, the resources that an indexing job uses depends on the number of available CPUs on the server.

Procedure

  1. In IBM Cognos Administration, on the Index Search tab, click Index.
  2. On the Edit Settings page, click Advanced.
  3. On the Advanced page, use the following table to set the advanced parameter.
