IBM Workload Simulator for z/OS and OS/390

Workload Simulator provides native support of multiple client applications that run "on top" of TCP/IP; that is, TCP/IP handles all routing and delivery between the Workload Simulator host and the system under test. Workload Simulator implements its connection to
TCP/IP on the local host using the macro API.

SNA logical units (LUs) can be simulated by Workload Simulator while
executing as a VTAM application program. General support is provided for LU types 0 to 7, with special support for the LU 2, LU 3, LU 6.2, and LU 7 data streams.

The expanded SNA portfolio provides CPI-C (LU 6.2) transaction program simulations to test existing LU 6.2 applications, execute stress or performance testing, and test applications still under development.

WTM guides the user through the test process. WTM can help users develop and manage test causes, automate test runs, and analyze results. For even more flexibility, WTM offers three modes of operation that control the amount of interaction the user can observe through Workload Simulator.

The flexible generation of scripts include Structured Translator Language (STL), Interactive Data Capture (IDC), NPM/LU 2 Reformatter and Script Generator.

Workload Simulator offers various utilities for users as they test their networks, including ISPF Interface, Display Monitor Facility, Run-time reports, and ITPECHO

Workload Simulator provides the utilities to analyze test results, including Loglist, Log Compare, and Response Time.
