Identifying Control-D Chunks on Spool (JES2 Only)

Control‑D provides the ability to uniquely identify each chunk that is sent to the JES output queue. This is done by appropriately setting the OUTGROUP field (GROUPID in JCL, O‑GRP‑N in SDSF) for the chunks that Control‑D sends to the spool.

Control‑D can place the following types of identifiers in the OUTGROUP field:

• original job name of the report
• user name of the user (for example, recipient) who is to receive the report
• printing mission name
• unique time stamp
• specific string specified in the printing mission

To activate this feature, do the following:

1. Add a special OUTPUT statement to the Control‑D Printers Control monitor procedure (CTDPRINT). It must be coded as follows:

   //OUTGROUP OUTPUT GROUPID=CONTROLD

   If the site runs more than one Printers Control monitor (CTDPRIN2, and so on), add this DD statement to all the Printers Control monitor procedures.

2. Add operand GROUPID=CONTROLD to all OUTPUT statements in the Printers Control monitor procedures. This operand must be coded in the first operand in the OUTPUT statements.
3. Set the OUTGRP Control‑D installation parameter in member CTDPARM in the IOA PARM library, as detailed in the INCONTROL for z/OS Installation Guide: Installing.

   We recommend specifying OUTGRP=Y, and using the GROUP parameter in the printing mission definition to define OUTGROUP processing. For information about using the GROUP parameter, see the chapter that discusses printing mission parameters in the Control‑D and Control‑V User Guide.
