Hello All,
I am facing lot of problem with a flow where there is a need of increasing jvm heap size. I have referred all the resources provided to me and got little bit of confusion.
What the confusion is what is the difference in increasing broker heap size and execution group heap size. will there be any effect if I increase broker heap size rather than increasing all the execution group's heap size. |

Neither the broker nor the EG heap are the same as the EG JVM heap.
That is, there are "three" heaps. But really, there are only two. The EG has a heap/stack for the ESQL/runtime portions, and a JVM heap for the Java runtime portions.
The broker exists only as a) bipBroker, which may never need you to manually adjust the heap, b) a collection of DataFlowEngine processes, one per EG, c) the bipHttpListener.

Jeff,
In my situation I get java.lang.OutOfMemoryError while executing java code in JavaCompute. This means I need to increase the jvm heap.
For this I can go for
1. mqsichangeproperties BrokerName -e EG -o ComIbmJVMManager -n jvmMinHeapSize -v value
mqsichangeproperties BrokerName -e EG -o ComIbmJVMManager -n jvmMaxHeapSize -v value
but we have other command
2. mqsiservice BrokerName -r MinJVMHeapSize=value
mqsiservice BrokerName -r MaxJVMHeapSize=value
What are these for????? |

mqsiservice should only be run under the auspices of a PMR - that is,only under the instructions of IBM support.
You will notice, for example, that it's not a documented command.
If you received a PMR that gave you those instructions, then ask the support person what the difference is.
