Custom queries

This topic provides tips and suggestions regarding queries that you create for the DFSMSrmm Status feature.

You must use uppercase characters for the character string values in your queries, such as dataset name or volume serial number, otherwise the data is not displayed in the Tivoli® Enterprise Portal. A single DFSMSrmm table query can return a maximum of 4000 rows. This behavior prevents storage shortages and potential abends in the Tivoli Enterprise Monitoring Server. A query (for example using the predicate JOB=$*) might match an extremely large number of dataset detail rows. This processing load can negatively affect all other IBM® Tivoli Monitoring applications.
