Specifying the TOMID and TOMPLEX parameters
The default value of the TOMPLEX parameter is an asterisk (*), which specifies any or all TOMPLEXs (as appropriate for the requested function).
If you omit the TOMID and the TOMPLEX parameters, a search is performed to find an active TOM on the system on which the EXEC is scheduled. This method is recommended.
When the TOMPLEX parameter is specified, for example TOMPLEX(BBEX01), a search is performed to find an active TOM belonging to the TOMPLEX named BBEX01 on the MVS system where the EXEC is scheduled.
Tip: For faster searching, add an asterisk to the end of your partial query. Example: cert*
