Purpose
Using the MODIFY SUPP
(suppression) command, you can change the message suppression level
after VTAM® has been started.
Some error messages, such
as those indicating abnormal termination of a task, are classified
as "insuppressible" and cannot be suppressed. Other messages
that cannot be suppressed include those requiring a response from
the VTAM operator (messages
that end in "A") and those resulting from the operator's status
inquiries (messages resulting from a DISPLAY command). See z/OS Communications Server: SNA Messages for a definition of these message categories
and the classifications of specific VTAM messages.
If
the PPOLOG option is in effect, messages that are suppressed by the
MODIFY SUPP command or the SUPP start option are still sent to the
primary program operator, even though those messages do not appear
on the system console.
Also see
z/OS Communications Server: SNA Messages for information about message flooding.
Note: - Issuing a MODIFY SUPP command prevents specific messages from
being issued by VTAM. Before
issuing the command, make sure that you understand the potential effects
on Tivoli® NetView® for z/OS® command
lists and any automated operation facilities in your network.
- Message suppression might prevent message IST223I (indicating
the completion of the MODIFY SUPP command) from being issued by VTAM.
- You can use the MODIFY VTAMOPTS command (SUPP operand)
to perform the same function as this command.
Operands
- procname
- The procedure name for the command. If procname in
the START command was specified as startname.ident,
where startname is the VTAM start procedure and ident is
the optional identifier, either startname.ident or ident
can be specified for procname.
If procname in the START command was startname,
startname must be specified for procname.
