TM function

Purpose

This function groups commands and services that are general purpose. Normally they operate on "environmental" related items. For example the activation and deactivation of exits is done by the TM function.

Function identifier

Description of usage

Under the "catch-all" function TM, a number of commands are provided that allow you to alter some environmental parameters, activate and deactivate tracing, and also activate and deactivate ThruPut Manager user exits.

For instance:

/TM TRACE ADD IDENTIFIER(id) JOBNAME(jobname)

This command adds to the current tracing (if any) tracing for any job that matches the jobname specified.

/TM EXIT 6 ACTIVATE

This command activates Exit 6.

/TM CLASS ADD(F)

This command adds class F to the classes to be selected for ThruPut Manager processing.

The TM command function also provides support for unit name mapping. In some environments, the unit name specified in JCL might be re-mapped at execution time to a different unit name, or the unit name might not be present at all. To allow ThruPut Manager to take this into account at Job Analysis time, you can use the TM UNIT commands:

/TM UNIT SET DEFAULT(DASD)

This command establishes that any DD statement that specifies a new allocation without a unit name will default to the unit name DASD.

/TM UNIT HANDLE(DISK,WORK) AS(DISK90)

This command maps the unit names DISK and WORK into the unit name DISK90.
