You can customize utility session rules by doing either of the following:
- Create a custom rule with fewer sessions than the system default.
This option is useful if the client machine is not powerful enough to use all the sessions at the same time or if you want to restrict utility sessions to make more sessions available to other job types.
- Use the UtilityDataSize session query band to specify a small or large data size for the session, as in the following example:
SET QUERY_BAND='UtilityDataSize=LARGE;' UPDATE FOR SESSION;
