Hello,
System: Solaris SPARC
Broker: 6.1.0.10
I tried to activate a .trc file for garbage collection data for some analysis. After executing the command:
mqsichangeproperties BROKER -e EG -o ComIbmJVMManager -n jvmSystemProperty -v"-verbose:gc -Xverbosegclog:/tmp/luci/gc.trc"
nothing happened. So I thought maybe a restart may be required. After the restart all the EG start successfully except the one where I set the value for this property.
The log from /var/mqsi/components/BROKER/stderr only stated: 2012-07-30 22:06:33.347452 AdminAgent started. Process ID : 1474 Broker is: BROKER
The log from EG specific UUID from the same directory states:
2012-07-30 22:20:02.041583 Execution group started. UUID is: 'UUID'. Broker is: BROKER
Unrecognized option: -Xverbosegclog:/tmp/luci/gc.trc
-----------------------------------------------------------------------------------
I tried the following to reset the value back to null:
1. Execute command: mqsichangeproperties BROKER -e EG -o ComIbmJVMManager -n jvmSystemProperty -v "" but it is not processed from SYSTEM.BROKER.ADMIN.QUEUE
2. Stop the broker, execute the command from step 1 so it will exist in the queue and wait for processing, start the broker hoping that when the EG PID is starting it will process the command and reset the value, unfortunately the EG only has a PID for 5-10 seconds and then it's 0 and does not start, the command (even if it is not in the ADMIN.QUEUE anymore is not processed)
Please help me with a solution for this situation. I am thinking that maybe someone else had to go though it before.
Thank You in advance,
Lucian |

Ideally you wouldn't have started this tracing without a PMR in place to guide you through it.
In general, the only tracing you'll find of use in here is any GC being done by your own code. And where your own code is making use of the Broker APIs, you may not find a significant amount of use there either.
You seem overly concerned that you can't start a particular EG. It seems a waste of time to me to spend trying to fix it, when you can instead delete and recreate it. |

This is a test EG, but it seems weird for a EG to be unable to start due to a property value.
Thank You for the advice, the deletion and redeploy will be the approach I will use, but I also thought there could be a solution to override the property value with null while the EG is stopped bub the broker is running. |

It should be fine to do what you did. I mean, except for setting the parameter in the first place... 
Apparently something is broken enough that the EG can't start up enough to accept the change in properties. |
