I think this isn't supported, at least on Windows.

It's not the same command.
I remember there being an answer for this on this forum somewhere... try using Search.

Again, it's not supported on Windows, that I know of.
There are some ways to do it on AIX, but not otherwise.

Typically, you would increase the heap size for a specific execution group, and not the entire broker:
| Code: |
| mqsichangeproperties brokerName -e executionGroupLabel -o ComIbmJVMManager -n jvmMaxHeapSize -v newSize |

If you want to set the heapsize for the toolkit, then add -vmargs -Xmx384M to the mqstudio command line. This makes the toolkit startup much faster. This works for any use of eclipse in general.

Actually, it gets somewhat tricky with Broker Toolkit, particularly if you are trying to add the -data parameter as well... it seems best to wrap the, umm, parameter, to the -data parameter in quotes. Then the -vmargs can follow and work.
You can't put -data after -vmargs, cause everything following it is treated as a vmarg, and not an eclipse arg (as it should). So you have to put -data first, but then it wants to treat everything else as a file descriptor...

I'm curious, why do you want to do this?

Look at this ..
Broker prerequisites
Support for JRE 1.4:
Broker FixPack 6 or later is recommended.
The WebSphere MQ Real-time Transport is not currently supported with JRE 1.4.
The Configuration Manager is not supported with Java version 1.4.
The Configuration Manager and the Broker automatically look for the JRE in the directory <install dir>\jre which is populated at product install time with JRE 1.3.1. For the Broker to use JRE 1.4, rename the <install dir>\jre directory and replace this directory with the JRE 1.4 installation. This implies that the Configuration Manager and the Broker cannot run on the same machine if the Broker is configured to use JRE 1.4.
Only the IBM packaged JRE 1.4.2 for Windows is supported with the Broker, available on request from IBM Support. |

Thanks for the response..
BROKER is on windows, since CONFIG MANAGER cannot be run on jre 1.4.2.
So we are planning to run CONFIG MANAGER on jre 1.3.1
and BROKER on jre 1.4.2 on the same machine.
so how can i identify jre for CONFIG MANAGER and BROKER individually and upgrade it.
Any suggestion.

You can't.
They use the *same* JRE.

What situation?
Where you need to run Java 1.4 code from within Broker?
Have you considered using RMI?

Broker uses customize code which supports class 1.4.2.Since Broker and Config manager on same machine and uses java 1.3.1. We are getting error log saying class is not found?
To handle this situation..All I think is to run Broker and config manager in separate windows box.
Other than above approach..Do you guys think any?
Hope you have understood the situation.
