MQGET with wait - IMS Online programs

Hello,
 
We’re running MQ for z/OS V7.1.   Recently, one of our Applications revised several of their IMS online programs - they are putting a message to a queue in a midrange cluster and the transaction in IMS is waiting for that message to come back to a local queue.  The get wait time interval is one second.   The program needs to get a particular message from the queue so they are using CorrelId.   I had strongly recommended the response message have expiry – unfortunately the application did not do this so messages coming back in more than one second are stuck on this local queue (they have a batch job at night that clears the queue).
 
The average response time for these IMS transactions has increased, which I expected due to the get wait time.  However – the CPU time has jumped up considerably. 
 
My understanding of the mqget with wait is that as soon as a message comes into the queue, the program in the get wait state will browse the queue, looking for the message with correlid.   My question – when multiple programs are running and multiple messages are coming back, is it safe to say these programs are constantly getting notified a message is back and they browse all messages until they find the message they want ?  
 
In the hopes of reducing CPU, I’m leaning towards indexing the queue.   Does anyone have other suggestions?   
 
Thanks,
Judy Yeske

Client ini file

I always see a lot of you talking about the client ini file and things that you can set in it. Where is the
documentation for the client? I haven't searched recently, but I could never find any docs for the client previously.

Re: MQTC V2.0.1.5 (IBM MQ Vs Open Source Messaging)

I am definitely making it to the conference this year. Haven't registered yet but will soon. I am under a lot
of pressure to look at Open Source Messaging products but just have not had the time to dive in. I know it's
the MQ.......Conference, but was wondering if this topic "IBM MQ Vs Open Source Messaging" could be explored?

I would love to touch base with anyone who has lived in both worlds in the real world.

Conference feedback?

IMPACT is done, Interconnect is here.  The MQ Facebook page posted the schedule and the whole week fit on one page.  Something like 43 total slots for the week and no more than 3 simultaneous sessions in any given time slot, with most slots having only one MQ session.  MQ Tech Conference has almost as many sessions on Day 1 as Interconnect has all week.  I will DEFINITELY be supporting MQTC every year, but I'm unsure of whether to go to Interconnect next year.  I'm hoping to get some insights from people who attended this year.

 

So did you go to Interconnect?  How was it?  Will you be going back next year?

 

Incidentally, between now and September I'm offering a free pass to MQTC for each 40 hours of consulting that I work.  If you missed Interconnect or just want more technical training, set aside the week of September 28.

 

Kind regards,

-- T.Rob

Re: MQTT in WMQ 7.5

In WMQ V7.5 on Linux, are the Telemetry Clients (MQSeriesXRClients) and Telemetry Service
(MQSeriesXRService) components separately licensed components like the Managed File Transfer and
Advanced Message Service? Or, are they considered part of the WMQ base installation?

I could ask my IBM rep but I need a quick  answer.

AMQP connectivity to MQ

To anyone who hasn't seen it yet I put up a blog post on MQdev last week which talks about the new beta programme for MQ that allows you to connect MQ Light/AMQP clients to MQ.

The blog article is here https://www.ibm.com/developerworks/community/blogs/messaging and I've done a screen capture walk through showing how to install and use the beta. The You Tube link is https://www.youtube.com/watch?v=FaElJu_t-Zc.
 
I'd be interested to hear your feedback on it. Have you tried MQ Light yet? Would a more open protocol for MQ connectivity be useful?
 
Cheers, Matt

Conference sessions

Am I reading the schedule correctly?  Because it looks from this as though there are at most three concurrent MQ sessions at the conference and there are at least two slots every day where there is only one MQ session scheduled.  If I am correctly interpreting this, that means there is now officially more MQ content at MQTC than any other conference on the planet, with the possible exception of SHARE. 

 

Is there another track that wasn't posted?  Are those rooms *really* full in the slots where there is only one MQ session to go to?  Anyone who is there care to comment yet, or is it too early?

 

 

 

Kind regards,

-- T.Rob

refresh of AIX binary apps leads to "missing" MQ libraries. aka would setmqinst resolve this?

HI, 
 Got a development/configuration  problem on a development environment:
The app developers and the support staff stopped supporting their apps on our End to End servers.
 We of course conscientiously upgrade the MQ versions on those ETE servers on a semi-regular basis.
The last upgrade was from 7.0.1.3 to 7.1.0.4 last year sometime.   All the application are happy after the upgrade.
This week the binaries and their Configs are refreshed from a test environment that has the older MQ version
7.0.1.3 

Now the apps are complaining about not being able to find the MQ link libraries :
exec(): 0509-036 Cannot load program /xxxx/xxxxx/xxxxxx/bin/swmqharcv because o
        0509-150   Dependent module /usr/lpp/mqm/lib/libmqm.a(libmqm.o) could n
        0509-022 Cannot load module /usr/lpp/mqm/lib/libmqm.a(libmqm.o).
        0509-026 System error: A file or directory in the path name does not ex

Doesn't the setmqinst resolve this issue after an MQ v 7.1* upgrade? If yes would it still resolve this if I
repeat the setmqinst instruction?

Thanks

Windows log maint

Hi folks,

 

I recently was on an engagement where the customer uses linear logs on Windows QMgrs.  When I looked at the SupportPacs, I realized none of them work for this combination (or v7.5 either) so I wrote my own.  You can find the script and docs are here:

https://t-rob.net/2015/02/22/windows-mq-log-maintenance-that-really-works/

 

If you use it I'd really appreciate reports of combinations of MQ and Windows where it works or fails.  The code is GPL so you can use it for commercial purposes, modify it or whatever.  I'll happily incorporate any updates should you care to contribute bug fixes or enhancements.

 

Kind regards,

-- T.Rob
