Can somebody give me some guidance on how to measure performance for MQSI flows. Our MQSI development department complained on this issue, after an upgrade of CSD03 to CSD06 (MQSI ver. 2.1 / MQ ver. 5.2 on AIX).
Thanks.

Typically, you would send group of messages to a message flow and see how much time it took to process those messages. Also, you need to monitor your server stats (CPU, memory, etc). There are lots of other factor that may affect your performance. There is a supportPac on Performance for WMQI on each platform. Please take a look at supportPac website.

You can measure message rates on a Windows broker using the Windows Performance Monitor Message Enqueue rate counters.
It's difficult to measure the resource consumption of a particular flow - but easy to measure the throughput rate if you load up the input queue with a few thousand messages.
If you measure throughput at 100% CPU loading you can see the effect of changes on the flow.
IBM have a support pac book IP04 "Designing message flows for performance" - start with that! |

Hi,
Take a look at supporpace IH03. This pac contains a few nice applications that can calculate the throughput of messages. It allows you to test persistent and non-persistent messages and set other options within the configuration file.
Hope this helps,

The very best thing you can do is upgrade to v5 of the broker, you'll then get access to full accounting and statistics on a node by node basis if so desired.
Probably not something you can do overnight, however. Perhaps ask them to add a trace node and see if the trace file indicates a particular node, or type of node, is taking surprisingly long to complete?

There are lots of other factors that you need to consider before migrating to V5!!
I'd start with the list of changes that occurred in the system before you installed CSD6. I don't think IBM has added any performance degradation code in CSD6. Do you have baseline results that you are comparing against? If so, were they done in the same environment? You don't want to compare apples with oranges!!
As others have suggested, there are different ways of measuring performance for a message flow. You can adopt any one of those techniques.
Also, there are some 3rd party products, like Candle's OMEGAMON XE for WMQI, where you get plug-in nodes that you can add in your message flows to collect some perf. related stats.

When collecting accounting and statistics in V5 using XML with publications, why is a usernameserver not needed? I was able to try the example in the migration redbook on my local machine yet I never created a usernameserver.

V5 help says "If your applications use the publish/subscribe services of a broker, you can apply an additional level of security to the topics on which messages are published and subscribed. This topic-based security is managed by the User Name Server."
So you only need the UNS when you want to control access to topics. |
