9.5 Workload Simulator components
Requirements for Workload Simulator (WSim) are of two categories:
MVS requirements
General requirements
On MVS, WSim runs in virtual or real memory mode. WSim uses QSAM, BSAM
or BPAM access methods for tape, disk and unit record operations.
Authorization is optional when using the VTAM application interface to simulate
terminals, but performance is better if authorization is provided.
WSim requires at least 1500 tracks of 3390 DASD disk storage space for
partitioned data sets that contain:
Network definition statements and message generation decks.
WSim load modules.
Optional rate tables referenced by network definition statements.
Panels and CLISTs ...
