I've never had to resize QSYSOPR, but there was a new system value added in
V4R4 called QCFGMSGQ, which moves many of the (usually) useless messages
from QSYSOPR to another message queue, which IBM supplies and curiously
calls QCFGMSGQ.
I am in the hotel, so I don't have the luxury of a system to play on.
See the following page from my COMMON presentation, "Everything You Always
Wanted to Know about System Values (but were afraid to ask)":
Name: QCFGMSGQ V4
R4.0
Description: Message Queue for Configuration Messages
IBM Initial Value: 'QSYSOPR QSYS'
Length & Type: Character: 20
Value is a list.
Comments: Two values are specified:
- Message queue name.
- Message queue library.
QCFGMSGQ is the system value that allows you to
specify a default message queue the system will use
when sending messages for lines, controllers and
devices.
For best overall system results, create the message
queue that is specified for this system value with
the following attributes:
FORCE(*NO) ALWALR(*NO) SIZE (8 32 *NOMAX)
MSGQFULL(WRAP)
A suggested change to the default is the message
queue QSYS/QCFGMSGQ, which is supplied by IBM, and
has the above characteristics.
A change to this system value takes effect when the
line, controller or device description that supports
the MSGQ parameter is varied on.
User must have *ALLOBJ, *SECADM and *IOSYSCFG
authority to change this system value.
Note the following admonition that I have regarding this change, when
suggesting system values that you might want to change:
System Values You Might Want to Change
System IBM Initial Suggested Reasoning for Change
Value Value New Value
QCFGMSGQ 'QSYSOPR QSYS' 'QCFGMSGQ QSYS' This value will significantly
reduce the number of message
sent to the QSYSOPR message
queue into a manageable number
of messages. The new message
queue should only be consulted
for problem resolution, while
QSYSOPR should be kept in *BREAK
mode during the day to deal with
system problems. Note that
newly created writers will
default their messages to this
message queue which may not have
the desired effect.

Technical Discussion
Has anyone ever had to resize QSYSOPR? Our application software is
drowning
the operators message queue in meaningless messages. The message full
action of *WRAP doesn't work when messages are hitting to fast to wrap.
I was gonna create a new message queue named QSYSOPRX in QSYS with either a
greater number of increments than QSYSOPR's or *NOMAX. Then I was gonna
rename out the old QSYSOPR and rename in the new one, at a point in time
when I could log off the operators and get the queue out of *BREAK
delivery.
Seems kind of scary to me. I'm wondering whether I'd regret setting up
QSYSOPR with size of *NOMAX. I'm also wondering whether there's an easier
way to tweak the size of a message queue.
Any advice or warnings? Much thanks in advance...
