Overview

The CONTROLR step is a special processing step that is automatically generated by Control-M/Restart and inserted into the JCL of the job when Control-M/Restart processing is requested. The CONTROLR step provides the necessary instructions for the appropriate Control-M/Restart processing of the job.

The particular instructions included in the CONTROLR step depend not only on the type of processing requested, but on relevant parameters that can be taken from any of various sources:

• the CTRPARM and CTMPARM members in the IOA PARM library

  These are described in the customization section of the INCONTROL for z/OS Installation Guide.

• members in the Control-M/Restart PARM library

  Table 25 describes the members that can be found in this library.

  Table 25 Control-M/Restart PARM Library Members

  Member	Description
  $DEFAULT	Parameters defined in this member apply to all jobs processed by Control-M/Restart
  Local members	A local member and the parameters it contains are dedicated to, and apply to, a particular job. Parameters in a local member override parameters in the $DEFAULT member for the particular job.
  $EXCLUDE	This member is used to indicate DD statements and data set names to be excluded from Control-M/Restart processing.
  $KEEP	This member is used to indicate the names of data sets that must not be deleted by Control-M/Restart.

The parameters of the $DEFAULT (and local) members, and the format of the $EXCLUDE member, are described below.

• Job scheduling definitions

  Parameters in a job scheduling definition override corresponding defaults specified in the CTRPARM member in the IOA PARM library, and override defaults specified in the $DEFAULT member or local members in the Control-M/Restart PARM library.

• Special DD statements placed in the JCL for specific job steps

  These are relevant only to those specific steps of the job and override all other corresponding instructions.

• Windows and screens used to enter manual requests

  These parameters override any previously specified parameters, except those specified in special DD statements placed in specific JCL jobs steps in the job.

Although generation of the CONTROLR step is automatic, manual adjustment of the CONTROLR step is permitted.

This chapter contains a description of the CONTROLR step, followed by a description of the control parameters specified in the Control-M/Restart PARM library.
