Hi everybody,
Mq v6.0 uses the CPU 100% (windows2003 server) while running the application (example even when looking at the properties of a queue). Are there any methods to optimize this usage.

It shouldn't do that 
Are you up to date with maintenance? Both WMQ & Windoze?

MQ is made up of several different processes.
Which one is using 100% of the CPU?
Are you sure it's an MQ process, and not your application process?

| Is it possible that this is your application stuck in an MQGET loop with no wait (and no messages)? |

As suggested above, so one of those ALT+CTL+DEL things, click on Task Manager, click Processes tab, click CPU to sort 'em high-to-low. What is the name of the high-use task(s)?
If it/they start with amq...., it's an MQ module. If so, what is the exact name?

This is what I observed so far java.w.exe uses 100% cpu when the explorer starts up. And when working with the properties of individual queue's {amqZlaa0.exe,amqZlsa0.exe} keep using like 70 percent and rest amqpcsea.exe, amqzmuc0.exe use like 50. all things doesnot happen at once but during the process of handling they occur. When i compared with my personal system i see many(6) amqZlaa0.exe and amqZlsa0.exe(6) on my system is this becuase of me installing mq on my system many time(mean like uninstalling and installing as i was working on silent installtion before on my system) 
regarding the fix applied its the latest 6.0.2.3
thanks |

Sounds like your Java program is looping.

What is the javaw.exe doing in your system - is it an application using MQ? When does it start, how long does it run... Is its owner complaining of a slowdown?
The amqXXXXX.exe processes mainly work on behalf of the applications that are using MQ. Do any of your application owners (whether C, Java, .NET etc. programs) report a slowdown? |

Well i have know clue how the javaw.exe come up in the system,but i guess its the Mq that uses it. These are the file paths where it exists in C:\Program Files\IBM\Websphere MQ\gskkit\jre\bin
and C:|Program Files\IBM\Eclipse SDK30\eclipse\jre\bin
thanks |

You configured your MQExplorer to refresh way too often. You need to not refresh more often than once per minute or even once per 5 minutes...
Should this not be the case maybe your machine is on the lean side for memory and disk and you're paging to death...
Working as designed...

You can use Process Monitor, from Microsoft, to see the full path, to the executable, so you can see which copy of Java is the culprit.
