SPIN Parameter

For a spool data set:
  • JESMSGLG
  • JESYSMSG
  • SYSOUT ddname (JES2 only)
that is defined to be spun off and to be monitored by Job Log Monitoring, it is highly recommended to hold the output until Job Log Monitoring has processed the data set. Otherwise, you may lose information you would like to automate.
For the JESMSGLG data set you also need to verify that the output is not suppressed. In a JES2 environment the command
$D JOBCLASS(STC),LOG
must show the value YES for the parameter LOG. In a JES3 environment the command
*I,STD
must now show the value NOSTC for the parameter JESMSG. And, the command
*I,C=x
must not show the value NOLOG for the parameter JESMSG where 'x' is the class that is assigned to the started task jobs.
When Job Log Monitoring detects that a particular data set has been spun off by JES it issues the message INGY1333I after it has finished its processing of the data set. The message informs you that the particular spool data can be released now. For example, the job name or the job identifier along with the SYSOUT identifier of the message can be used to purge the data set:
JES2: $P O JQ(jnm|jid),OUTGRP=soid
JES3: *F,U,J=jnm|jid,DSN=...soid,CANCEL

Note that 'jid' is just the numerical part of the job identifier.

If the SYSOUT identifier is not present in the message the task could not determine the value.

The message INGY1306I indicates that monitoring has been stopped for a particular ddname and all corresponding spool data sets can be released.
