Maintenance-specific commands

Data Set Commander Version has a set of diagnostic commands that can help IBM® support personnel perform problem investigations.

The commands related to maintenance are as follows:

  • VER
  • DIAG
  • SNAP

These commands are invoked from any main command line of any panel. Each of them is prefixed with Data Set Commander.



The following explains each of these commands and how to use them.


MAINT creates a report that contains information such as applied APARS, current Data Set Commander version levels, and module versions. This report should normally be sent with any Data Set Commander problem report ticket (PMR).

You may enter the command DSC MAINT (shortcut IMAINT) from the main command line of any panel. It creates an DSC Maintenance Report in SYSOUT data set DD(IQILOGPR) of your TSO session.


This command displays the DSC Maintenance Report on your screen. You may enter the command DSC VER (shortcut IVER) from the main command line of any panel.


The DSC DIAG command (shortcut IDIAG) lets you turn on the Data Set Commander tracing and function logging facility. By default Data Set Commander runs with the tracing facility disabled.

Occasionally, IBM support may ask you to run a failing scenario while the Data Set Commander tracing facility is active.


The DSC SNAP command (shortcut ISNAP) provides you a snapshot of the current Data Set Commander in-core trace table (if active) or of the entire region of your TSO session.

Typically, when IBM support asks to run with Data Set Commander trace active, you are also asked to issue a SNAP command at the end of the failing scenario in order to output the in-core data into DD(IQITRSNP) of your TSO session so that it can be sent to IBM for further analysis.
