Messages included in the hardcopy message set are either commands
and command responses or unsolicited system messages. Installations
can control the selection criteria for commands and command responses.
Installations can control some of the criteria for unsolicited system
messages; some of the criteria are fixed.
You define criteria for messages in the hardcopy message
set at system initialization with the HARDCOPY statement in the CONSOLxx member
of Parmlib:
- For commands and command responses, the CMDLEVEL option of the
HARDCOPY statement controls the types of commands included in the
hardcopy message set.
- For unsolicited system messages, the ROUTCODE option of the HARDCOPY
statement controls the routing codes the system uses to select messages
for the hardcopy message set. If an option is not specified, the default
value is used for the hardcopy message set definition.
Once MVS™ has been initialized,
you can modify the criteria of the hardcopy message set using the
VARY HARDCPY command.
Unsolicited system messages for which the criteria are fixed are
those messages that match one or more of the following characteristics:
- Have descriptor codes of 1, 2, 3, 11, or 12
- Are WTORs
- Have no routing codes
- Have a message type specified
- Are hardcopy only messages.
In a JES2 complex, you define the hardcopy message set in the CONSOLxx
member of parmlib. If you are using the JES3 hardcopy log (JES3 DLOG),
it is maintained on the JES3 global processor for all messages issued
in the complex. For information, see z/OS JES3 Initialization and Tuning Guide.
