Simulation Procedure CTMSIM

Note: The CTMSIM simulation procedure provides basic simulation capabilities that are limited to Control-M for z/OS. Control-M/Forecast is a more comprehensive tool with advance capabilities and CTMSIM users are advised to use it instead. Control-M/Forecast is fully described in the Control-M documentation set in the following guides:

Control-M Getting Started Guide
Control-M User Guide
Control-M Administrator Guide
Control-M Utilities Guide

However, users requiring the Tape Pull List utility (CTMTAPUL), described in the following section, must still execute the CTMSIM simulation procedure, described in this section, since the Tape Pull List procedure uses files from CTMSIM as input.

The Simulation procedure mirrors the Control-M monitor flow for a specified period without actual job submission and without output processing. It takes into consideration all scheduling criteria including prerequisite conditions, time limits, quantitative, and Control resources.

Control-M and IOA files used as input to the simulation process are not updated as a result of this process. The statuses of the files after simulation are written to special simulation output files. The simulation assumes that each job ended execution with a condition code of 0.

The following Control-M and IOA files are used as input in the Simulation procedure. These files may either be actual production files or special files created specifically for forecasting purposes.

Table 265 Files Used as Input during Simulation

File	Description
AJF	Active Jobs file
RES	Control-M Resources file
CND	IOA Conditions file
STAT	Control-M Statistics file

The simulation produces the following output files:

Table 266 Files Produced as Output of Simulation

File	Description
SIMOAJF	Simulation Output Active Jobs file
SIMORES	Simulation Output Resources file
SIMOCND	Simulation Output Conditions file
SIMLOG	Simulation Output Log file

The Simulation procedure may contain several steps prior to the actual simulation processing step, depending on the environment to be used as input to the simulation run. For example

It may be desirable to use the production Active Jobs file as input.
It may be necessary to simulate the run of a specific day without relating to the current production jobs.
It may be necessary to resolve manual conditions prior to the simulation run so that all jobs are submitted.
