QSYSOPR message queue security

And in your CL, you could also DSPMSGQ QSYSOPR *PRINT.
I like to do that as part of the Shift Change / Daily Startup.
It is nice to have the report around for about a week,
because it sure beats looking at DSPLOG.

Just curious... Is the output from DSPLOG really that much different
than DSPMSG OUTPUT(*PRINT)? The DSPLOG also has an OUTPUT(*PRINT), if
the comparison was being made between spooled DSPMSG and an interactive
display for presentation of DSPLOG output. But even better IMO, the
DSPLOG has OUTPUT(*PRTSECLVL) to include the second level message
details, which AFaIK, the DSPMSG command still does not have.

I am not sure, but I think there is more system stuff in DSPLOG than in QSYSOPR. At least, that been my experience.
And QSYSOPR can be cleaned up / individual lines deleted by using F11.
And a utility like bytware's MPLUS Message Monitor can remove messages as it monitors the Message-Queue.

Also, programmers can have their programs send INQUIRY messages using SNDPGMMSG and other types to QSYSOPR.
