MQ-Jobs z/OS in parallel
Hello MQ'ers, some of our applications use MQ for a kind of dialogsystem and has a need of quickest answers as possible. I have a hint in mind that with (now) z/OS 4 parallel regions working on the same queue are the best performance. But this hint is very old and we are now on V5.2 and IBM has done a lot meantime. Has someone the latest informations, what are the best number of parallel regions ? I know there will be now absolut general answer. My interest is the MQS-View without application-design as cpu for one transactions etc. Thanks in advance for any hints and tips. bye, Frank --- --- Frank Wagner, IS-C2 D1, Allianz Lebensversicherung AG, MQSeries-Administration, MQ-Wrapper [EMAIL PROTECTED] Instructions for managing your mailing list subscription are provided in the Listserv General Users Guide available at http://www.lsoft.com Archive: http://vm.akh-wien.ac.at/MQSeries.archive
Re: IBM TRANSACTION AND MESSAGING CONFERENCE
U should go to the IBM site. BUT Two years ago the conference was held at the Las Vegas Hilton. I believe the cost on the room for the IBM conference was $159 USD per night. You could, if you search around get much lower rates. But then you would not be in the hotel and it would be a little more of a pain. The conference for both the MQSeries and CICS was about $1700 USD. Although you may not be doing CICS there are some interesting topics on MQ in the CICS sessions that you may want to see. If you don't prepay with that designation. You cannot get into those. Also there is a discount if you are a partner (Or at least there used to be!!) Transportation is pretty much unnecessary. You have quick access to the STRIP and it is an easy walk. Actually it's pretty enjoyable. If you have never been to Vegas, aside from the gambling, it is a Disney World for ADULTs. Breakfast and Lunch are provided at the conference and being Vegas you have more that a variety in both price and food to satisfy yourself. If you want to go to any shows, you should book them in advance as Vegas in the winter is a prime spot. Circus O'lea can be book by people outside the hotel 30 days prior to show. Expect to sit at the top row and bring binoculars. Try a show called SPLASH. It's a little adult so leave your religion home. Also try the Roller Coaster at New York, New York. IT's GREAT!. I went two years ago to Vegas and three years ago to Dallas. The conference is very very good, with tons of information for the newbie and interesting forecasting and new stuff for the Hard Core MQ'ers. Vegas is an added benefit!!

I send this information preliminary so so have more time left for planning: We closed APAR PQ59549 on Friday and built PTF UQ71197. I expect the PTF to be available in about two weeks (mid November). The DB2 V7 publications have been updated and are available on the DB2 Library web site at http://www.ibm.com/software/data/db2/os390/v7books.html. DB2 MQSeries functions DB2 for z/OS and OS/390 Version 7 adds support for user-defined functions that you can use to perform MQSeries tasks. MQSeries is the core of the WebSphere MQSeries product family. It is a flexible messaging system that lets applications communicate in a distributed environment. The DB2 MQSeries user-defined functions let you easily integrate MQSeries messaging with database applications. You can use the DB2 MQSeries functions to send messages to a message queue or to receive messages from the message queue. In addition, you can send a request to a message queue and receive a response. One set of user-defined functions that DB2 provies are DB2 MQSeries functions, which integrate MQSeries messaging operations within SQL statements. The functions help you integrate MQSeries messaging with database applications. You can use the functions to access MQSeries messaging from within SQL statements and to combine MQSeries messaging with DB2 database access. The MQSeries functions are installed into DB2 and provide access to the MQSeries server using AMI (Application Messaging Interface). AMI supports the use of an external configuration file (the AMI repository) to store configuration information. AMI uses two key concepts: service point and policy. A service point is a logical endpoint from which a message may be sent or received. Policy defines the quality of service option that should be used for a given messaging operation. The MQSeries functions can read, receive, or send messages to the queue specified by the service and policy in the AMI repository. The functions can be scalar or table functions. For more information on MQSeries functions, see the function descriptions in Chapter 3, Functions on page 153 of SQL Reference. P.S.

The changing of the value for max uncommitted messages will affect the size/number necessary for log space, but, I don't know that it would affect the checkpoint processing. Per Paul's note regarding when queue space is cleaned up, it basically takes two checkpoint's after a queue has been emptied to clean up the space on disk. What I'm interested in doing is forcing those checkpoints to come more frequently than the default of 10,000 (per the documentation) operations between checkpoints. I don't know that max uncommitted would have any affect on that processing. I was hoping for an entry in say the qm.ini file that would tell MQ to take these checkpoints more frequently, say every 1,000 operations.

I tried what you suggested. Inside the script there is no return code being
returned at least not one I am trapping. I executed the followig code
suggested by someone on the LISTSERV:
SYSTEM)$Import $MessageFlowFile $DeleteOption $LabelOption $UUIDOption)
;
$MyScalar = $?;
print \nReturn Code = $MyScalar;
The value printed is zero ('0') BUTwhen I try it outside of PERL using
your suggestion I get a value:
C:\Program Files\IBM\WebSphere MQ Integrator 2.1\Toolmqsiimportmsgflows.bat
c:\myfile.txt -d -l -u
file:/C:/Program Files/IBM/WebSphere MQ Integrator 2.1/Tool/Parser: 1, 0:

getMsgFlowsFromExportFile.
An exception was caught by the ImportMsgFlows utility in method
getMsgFlowsFromExportFile. The exception text is: java.lang.Null nt
operation will end.
Retry the operation if possible. If the exception still occurs, contact your
IBM support center.
C:\Program Files\IBM\WebSphere MQ Integrator 2.1\Toolecho %ERRORLEVEL%

I do not know the difference between executing the 'SYSTEM' command inside
the script as opposed to executing the command from the command line and
using the ERRORLEVEL variable. I have a work around for the moment. I can
trap the output from the command and do a pattern match on the BIP\d+[SE]
character string. If I get a hit I know I have an eror.

I was just looking at a WEB site for the book perl by EXAMPLE this was a
statement about the $? and $! special variables. So maybe the return Code
point is mute!!
You can't rely on these variables to check the status of pipes, back-quoted
strings, or the system() function when executing scripts under the
Windows operating system. My recommendation is to capture the output of the
back-quoted string and check it directly for rror messages. Of course, the
command writes its errors to STDERR and then can't trap them, and you're out
of luck.

Hello Bobbee,
Try to execute your command line from the command prompt and type in:
c:echo %ERRORLEVEL%
right after for both successful and unsuccessful scenarios. This way you
will check if you command actually returns the error code you expect. Here
is a simple transcript to ensure you it actually must work as you expect:

Re: IBM TRANSACTION AND MESSAGING CONFERENCE
A few weeks ago I was able to get some discounted prices for the Hilton - the rate varies, depending on the day of the week, but out of seven days, four were cheaper, and the rest were the same as the conference discount. And there are hotels within a block that are cheaper, but it takes some digging. It is very convenient to stay at the Hilton - the convention center is attached to the hotel. It is very nice to be able to go to your room between sessions. On the other hand, it will not be as hot as it was the last time the conference was in Vegas, so if you like walking, you will get a little exercise. If memory serves me right, the conference fee was lowered by $200 a few months before the conference to try to bring in people who were undecided. I can't guarantee that will happen again. Also, because the travel industry usually promotes travel with reduced rate packages for trips one or two months in advance, you may find some bargains starting to appear this month. Believe it or not, with all the spectacles in Vegas, you can find a surprising amount of entertainment for a cheap price (weather permitting). But.. they make it easy to spend money! I agree with Bobbee that the value of the technical conference is outstanding. It is like taking several training classes for the price of one (but you just don't get the hands on experience - Wouldn't that be great if IBM could setup some hands-on workstations there Or at least more real live demonstrations?). Plus, you are getting information directly from the developers, in many cases. The vendor demonstrations can also be valuable - by looking at what thay are offering, they tend to show you what the real-world needs are (or will be).

BUT Two years ago the conference was held at the Las Vegas Hilton. I believe the cost on the room for the IBM conference was $159 USD per night. You could, if you search around get much lower rates. But then you would not be in the hotel and it would be a little more of a pain. The conference for both the MQSeries and CICS was about $1700 USD. Although you may not be doing CICS there are some interesting topics on MQ in the CICS sessions that you may want to see. If you don't prepay with that designation. You cannot get into those. Also there is a discount if you are a partner (Or at least there used to be!!) Transportation is pretty much unnecessary. You have quick access to the STRIP and it is an easy walk. Actually it's pretty enjoyable. If you have never been to Vegas, aside from the gambling, it is a Disney World for ADULTs. Breakfast and Lunch are provided at the conference and being Vegas you have more that a variety in both price and food to satisfy yourself. If you want to go to any shows, you should book them in advance as Vegas in the winter is a prime spot. Circus O'lea can be book by people outside the hotel 30 days prior to show. Expect to sit at the top row and bring binoculars. Try a show called SPLASH. It's a little adult so leave your religion home. Also try the Roller Coaster at New York, New York. IT's GREAT!. I went two years ago to Vegas and three years ago to Dallas. The conference is very very good, with tons of information for the newbie and interesting forecasting and new stuff for the Hard Core MQ'ers. Vegas is an added benefit!!

[no subject]
Hello Bobbee:
I am glad you got your thing working. I have never seen this problem in NT; still I am
inclined to get that information from Perl by example with a grain of salt because
the intercepting of both standard input and standard error always works for me on NT
and I use it pretty often. Or they might mean NT and Windows 9x, not just NT when
they mention Windows. Here is an example of how you intercept both standard input and
output in perl on NT:
cut here--
D:\type a.pl
#!/usr/bin/perl -w
print THIS IS STANDARD OUPUT\n;
print STDERR THIS IS STANDARD ERROR\n;
D:\perl a.pl
THIS IS STANDARD OUPUT
THIS IS STANDARD ERROR
D:\perl -e $o = `perl a.pl 21`; print grep(/ERROR/, $o) . \\n\;
1
D:\perl -e $o = `perl a.pl 21`; print grep(/WILLNOTBEFOUND/, $o) . \\n\;
0
D:\
cut here--
One peculiarity (it is not NT- or other platform specific) is that Perl returns a
system return code multiplied by 256 (it is because on Unix, it uses the return value
from the system call wait()). So for %ERRORLEVEL% 18 it should be 4608 (but no way
zero!):
cut here--
D:\type a.pl
#!/usr/bin/perl -w
print THIS IS STANDARD OUPUT\n;
print STDERR THIS IS STANDARD ERROR\n;
exit 18;
D:\perl -e $r=system('perl a.pl'); print $r, '==', $?
THIS IS STANDARD OUPUT
THIS IS STANDARD ERROR
4608==4608
D:\perl -e $r=system('perl a.pl'); print $r8, '==', $?8
THIS IS STANDARD OUPUT
THIS IS STANDARD ERROR
18==18
D:\
cut here--
Also make sure you use at least more or less fresh Perl version (5.6 or later must be
fine).
Hope this will help,
Pavel

I tried what you suggested. Inside the script there is no return code being
returned at least not one I am trapping. I executed the followig code
suggested by someone on the LISTSERV:
SYSTEM)$Import $MessageFlowFile $DeleteOption $LabelOption
$UUIDOption)
;
$MyScalar = $?;
print \nReturn Code = $MyScalar;
The value printed is zero ('0') BUTwhen I try it outside of PERL using
your suggestion I get a value:
C:\Program Files\IBM\WebSphere MQ Integrator 2.1\Toolmqsiimportmsgflows.bat
c:\myfile.txt -d -l -u
file:/C:/Program Files/IBM/WebSphere MQ Integrator 2.1/Tool/Parser: 1, 0:
Invalid document structure.

An exception was caught by the ImportMsgFlows utility in method
getMsgFlowsFromExportFile. The exception text is: java.lang.Null nt
operation will end.
Retry the operation if possible. If the exception still occurs, contact your
IBM support center.
C:\Program Files\IBM\WebSphere MQ Integrator 2.1\Toolecho %ERRORLEVEL%
18
I do not know the difference between executing the 'SYSTEM' command inside
the script as opposed to executing the command from the command line and
using the ERRORLEVEL variable. I have a work around for the moment. I can
trap the output from the command and do a pattern match on the BIP\d+[SE]
character string. If I get a hit I know I have an eror.
bobbee
PSS
I was just looking at a WEB site for the book perl by EXAMPLE this was a
statement about the $? and $! special variables. So maybe the return Code
point is mute!!
You can't rely on these variables to check the status of pipes, back-quoted
strings, or the system() function when executing scripts under the
Windows operating system. My recommendation is to capture the output of the
back-quoted string and check it directly for rror messages. Of course, the
command writes its errors to STDERR and then can't trap them, and you're out
of luck.

Re: NT/2k: trigger monitor stalls in batch window, need Enter key .
Title: RE: NT/2k: trigger monitor stalls in batch window, need Enter key . Just curious.

Re: SYSTEM.CHANNEL.SYNCQ
Thanks Paul - I would echo the need to make sure you are up-to-date on maintenance, especially make sure you have PQ26840 applied. It was a very early APAR on V2.1 so you may well have it already, but it could be the cause of your problem if your queue depth really is growing out of proportion to the number of channel instances and the number of records each channel instance could have. Cheers Morag (now back from conference and also back from a trip to windy Shetland where she got stuck when all planes were cancelled due to high wind - normal service will be resumed shortly) Morag Hughson WebSphere MQ for z/OS Development Internet: [EMAIL PROTECTED] Bahman wrote: Thanks Rebecca, I'll go through your suggested path and delete the messages that belong to non-existing channels. But, while I am not adding any new channel, I see this queue is growing. Any idea why? Rebecca wrote: Sorry, no. Perhaps Morag H. would care to comment. -- Rebecca Morag is away as a UK User conference for a day or two so let me answer in her place. The SYSTEM.CHANNEL.SYNCQ contains essentially two types of messages, both to do with storing channel status. 1/ There is a message (possibly two) for each instance of channel that has run and transferred a persistent message to a remote partner. These messages maintain the synchronisation state between the two ends of the channels. If you delete these messages your channel will forget where it got to. This will almost certainly lead to sequence number problems since the channel will start at 1 again and you will have to issue RESET CHANNEL. In the worst case, if the channel was indoubt, you may may also cause messages to be duplicated. 2/ There may also be a message recording the status of the channel. In other words, whether the channel is STOPPED, RETRYING etc etc. If you delete these messages the worsed that will happen is that when you recycle your Queue Manager a channel will come up inactive rather than STOPPED or RETRYING. Now there were a few problems with the initial implementation of the type 2 messages. You could find that even a channel retrying would add a few more of these messages. I would ensure that you are on the latest service level for whatever release you are running. In the general case though don't be fooled into thinking that you've got a problem with the queue just because you have more messages on there that you have channels. Since you have a Type 1 message for each *partner* you must consider how many locations you are talking to. So a single RCVR channel which receives connections from 100 other Queue Managers will, quite rightly, be responsible for 100 messages on this queue. Hope this helps, P.

Say what? (American expression for where did you get that silly idea?) *** what I meant was currently we have one common xmitq for sending reply msg (both persistent and non-persistent msg) back to interfacing qmgr. As shared queue do not support persistent message, we are not suppose to put persistent msg into shared queue. Hence, if I were to convert my existing xmitq to shared queue, I will compromise the persistency of those persistent msg. Hence I plan to use a new shared xmitq(for non-persistent msg) and existing xmitq remains (for persistent msg). You should have no problem sending persistent and non-persistent messages to the same xmitq. *** yes I am able to send both persistent and non-persistent msg through same xmitq but if the xmitq is a shared queue, in the event of any MQ or CF failure, those persistent msg will be gone. That's why I thought of using different xmitq - a normal xmitq for sending persistent msg and a shared xmitq for sending non-persistent msg. I have thought of a bypass method to hardcode the MVS qmgr name as the ReplyToQmgr in the application pgm putting the request message So you want your reply to go to MVS? I don't get it. *** I was trying to send reply message back from a CICS pgm (using CICS DPL Bridge) to AS400 MQ. In the AS400 MQ application, I've specified a ReplyToQueue, in OS390 MQ I've created this replytoqueue with a specific xmitq name specified in the xmitq attribute. But the OS390 MQ ignores the QR definition, it is always picking up the xmitq (with same name as the AS400 qmgr). Hence I derived that when CICS DPL bridge did the MQOpen, it used the AS400 qmgr name in the MQOD. So in the AS400 MQ application. I hardcoded the ReplyToQmgrName as the OS390 qmgrname and now OS390 MQ resolved to the QR of the ReplyToQueue and used the right xmitq. Please clarify what are you trying to accomplish. *** The above are what I gathered from my testings. I'm not exactly sure if it is supposed to be working this way. Any kind advise will be appreciated. -Original Message- From: Geok Hoon FOO [SMTP:[EMAIL PROTECTED]] Sent: Friday, November 01, 2002 8:07 PM To: [EMAIL PROTECTED] Subject: MQ CICS DPL Bridge Query Hi, MQ perform queue name resolution based on the qmgr name setting in MQOD during MQOPEN. In our setup, we are using CICS DPL Bridge whereby the reply message is returned back to a xmitq by CICS bridge program. The issue now is CICS Bridge always use the ReplyToQmgr (eg MQP11 which is defaulted by our AS400 QM during the mqput by application pgm in AS400) in the MQMD of the request message as the qmgr name for the MQOPEN. So the problem is as this qmgr name (MQP11) is different from the MVS local qmgr name (MQP1), MVS QM ignores the ReplyQ (intended for sending reply msg back to AS400) and always look for a xmitq with the same name as the qmgr name in MQOD (ie MQP11). This pose a issue during share queue implementation. I can not convert the existing xmitq as share queue 'cus share xmitq only support non-persistent msg. Hence I plan to use a new shared xmitq(for non-persistent msg) and existing xmitq remains (for persistent msg). But with above constraint, MVS MQ is not able to pick up this new xmitq (specified in the QR ReplyQ definition). I have thought of a bypass method to hardcode the MVS qmgr name as the ReplyToQmgr in the application pgm putting the request message, but as this involves changes to our existing applications, it is not favourable. Does any one know of a better solution which is transparent to application codes. Thanks in advance. Geok Hoon. -- -- Warning : Privileged/confidential information may be contained in this message.

Re: Why MQ Cluster or MQ List
You are comparing MQ Cluster and MQ List? Do you mean distribution list? Clustering and distribution lists are not related. A distribution list puts the same message to more than one queue. In a cluster you only put one message to one queue. In a cluster you can have a queue on more than one queue manager by the same name within a cluster. When you do a put, it will only put the message to one of the queues in the cluster. When you open the cluster queue, it will either open one of them in the cluster and put all messages with that object handle to one queue, or it can put the message to all queues in a round-robin fashion, depending on the option chosen in your open options. Now that's out of the way. The main advantage to clustering is job security because it can be very high maintenance. So if you need to create work for yourself, add clustering. Not everyone has had a bad experience with clustering, but I think everyone will agree it is sometimes difficult to maintain and troubleshoot. With every release, IBM says clustering was bad in the previous release but now it is better. I have not had the chance to test it in 5.3 yet though. Clustering gives you a cheap way to balance your workload across queue managers (probably across machines) so you can scale your application. I say it is the cheap way because it is not balanced, it is round-robin. If you have a complex network with many to many connections, clustering can reduce the number of channel definitions. This is because it creates channels as needed automagically. I have used clustering for this purpose before. If a queue manager becomes unavailable, it routes all messages to the remaining available queue managers. This is cheap availability but not good for HA because messages will get stuck on the failed queue manager. Also, it doesn't react to the queue manager's availability very well and sometimes messages get stuck. You should carefully evaluate if clustering is right for your architecture. Do not use it just because it is cool or because some IT director thinks it will solve all your problems. The main advantages are: - Spread workload across queue managers - Provides a cheap, but unreliable psuedo-failover solution - An application can easily put a message on a queue on another queue manager without altering the queue manager - Can be more or less administration depending on your luck What about distribution lists? They are good if you want to send the same message to many queues on many queue managers. With this, you can put the message once rather than 20 times. It is a useful feature. If you need to send the same message to many places also consider pub/sub if that meets your needs.
