Hi all,
we think about using JMX within the Message Broker JVM. Therfore it's necessary to set certain JVM properties such as -Dcom.sun.management.jmxremote or others.
I couldn't find anything about that issue within the documentation.
Does anybody how to set JVM properties for the broker JVM?
Does anybody use JMX within the broker JVM?
Thanks,
Oli |

What are you trying/thinking of using JMX for? Remember, also, that every ExecutionGroup has it's own JVM - there isn't a "broker" JVM.
There is an environment variable, IBM_JAVA_OPTIONS or some such.
If you search here you should find some hints on that.

| We are trying to use JMX to change log levels at runtime. It's clear that there is no broker JVM and I think therefore the environment variable IBM_JAVA_OPTIONS is not very useful as it seems to be global and not per Execution Group. |

Hi jefflowrey,
Just want to know more about JVM for execution group.

Every execution group has it's own JVM, there is not one JVM that is shared by all execution groups defined to a particular broker.

Thanks Jefflowrey for your reply,
Still i am not convinced. Is that still valid for MB V6.0?
When i am debugging a java code, i am using the command mqsichangeproperties. Here, i am giving Broker JVM and a port number as an argument along with execution group name. To subsequently debug another flow with a JCN node in a different execution group we will again use
masichangeproperties Broker JVM, execution group name, a different port number.
I am not able to understand where i am mentioning a different JVM for execution group.
I searched on the infocenter, i did not get more information on this. Do have any link where it talked about separate JVM's for execution group, please provide it to me.

I just came across this while checking IBM message broker V6.0 documentation with regard to the JVM <http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r0m0/index.jsp?topic=/com.ibm.etools.mft.doc/ac55030_.htm>
I hope this answers your question.
Regards!
