Session Caching

In Report Studio, Query Studio, and IBM® Cognos® Viewer the results for previous requests to the database are cached for the duration of a session when session caching is enabled.

To increase performance, for subsequent queries, IBM Cognos software uses cached results for some actions rather than accessing the database. This applies when the same results can be used or when the new results are a subset of the cached results. You can disable session caching at the server level or at the package or report level.

Because performance may be affected, you may want to disable session caching at the server level in the following situations:

You may also want to disable session caching for individual reports because of high resource consumption, for example, reports that use bursting.

You can also enable and disable session caching for specific queries in reports in Report Studio (see the IBM Cognos Report Studio User Guide) and for models in Framework Manager (see the IBM Cognos Framework Manager User Guide).

Session caching for new models and reports is enabled by default. Existing packages and reports retain existing session caching settings.
