Hi,
I'm covering WebSphere MQ for z/OS 5.3 for a few weeks and MQ isn't exactly
my speciality, so please be patient!!

and overflowed to the "dead letter queue". There was a "bad" message in the
local queue and all subsequ

It's mostly a bandwidth problem. The purpose of all this is to write
the BLOB to an EMC Centera box, which is a network attached storage
device. It's got massive capacity, but it's not especially fast. But
the real problem is that the Solaris machine is bandwidth constrained.
It's getting gigs of d
Ok getting the picture. What is slow about the processing on the Solaris
end? Are you compressing the data before storing it? Problems storing it in
a DB? Are you hitting a CPU limit? An I/O subsystem limit? Does running
multiple processes against the queue help?

Sorry had my blinkers on. As others have said one solution is to send a
STOP message, I have done this using a different MsgType but the MQFB_QUIT
is probably more valid. Arjan's idea of get disabling the queue is possible
if you are prepared to permit +set access to clients and issue an MQSET API
You could try "rcrmqobj -m whatever -t syncfile" to recover it.
I've seen this sort of damage before, and that command usually fixes the
problem.
Cheers...

Is MQ 5.3 Officially supported for WMQI 2.1?
We currently have WMQI 2.1 CSD4 with MQ 5.2 on Solaris 8. We are thinking of upgrading

Hello,
We are trying to get to a parallel sysplex. We are running into issues on how to
transition MQ Series. We do not have DB2,
so we can not use the queue sharing. Are
there any other solutions for a parallel sysplex with

Thanks, Christopher. We had not downloaded CSD4. I do see it ( and the
setTempQPrefix() and getTempQPrefix() methods) in the memo.ptf.
If this had been released sooner, I could have saved someone a lot of
coding. They just did maintenance on this and released with 5.3 CSD3.

It may be (although see below) .. if you have a luxury of changing the application.
Otherwise, blitting with MQGET permission on the queue after starting a clean shutdown

Yes, I was exaggerating a bit. But I could have sworn it was just

I didn't know you could intermix JMS with JAVA. The developers were trying
to hold to a J2EE standard that JMS somehow affords. After reading

No, not that I know of. There isn't really anything to stop you from

You are correct you can use the accessQueue method to accomplish this in
the base Java classes. However your original issue is with JMS. If you take
a look at the JMS portion of that same manual you will see that the

I guess we come from different schools; sending a "quit" message seems quite elegant

If it is possible you will probably need tow set of Databases and two QMGRS.

Can you have a 'shutdown' command that runs a program to send a report
message to the app? With a feedback code of MQFB_QUIT ? The app /
