Controls the display of IST663I, IST664I, and IST889I messages when searches that might not result in a session being established fail to locate the target resource. The FSIRFMSG and RSIRFMSG start options can be used in conjunction with DSIRFMSG to generate additional messages as part of this message group.
  • The FSIRFMSG option controls whether the IST1704I, IST1705I, IST894I, and IST895I messages are displayed.
  • The RSIRFMSG option controls whether the IST1460I, IST1461I, IST2102I, IST2103I, and IST2104I messages are displayed.
DSIRFMSG=ALLSSCP
Specifies that messages are to be issued in all SSCPs.
DSIRFMSG=OLUSSCP
Specifies that messages are to be issued in the SSCP of the original logical unit (OLU) only.
DSIRFMSG=NONE
Specifies that messages are not to be issued in any SSCP.

You can change the value of DSIRFMSG with the MODIFY VTAMOPTS command while VTAM® is running.

Recommendation: Because of the volume of messages that can be generated, it is not recommended that this option be enabled during normal operation. Instead, it is recommended that this option be enabled (using the MODIFY VTAMOPTS command) on all necessary hosts only when trying to diagnose specific problems. Once the problem has been diagnosed or documentation has been collected, this option should be disabled once again (using the MODIFY VTAMOPTS command).
