Hi All,
Is there any way I can check the JVM min and max heap size for a particular execution group ?
Regards,
Rahul |

If u use CMP API you can use it , here is the sample code
public HashMap getExecutionGroupParameters(ExecutionGroupProxy aEgProxyObj) {
String minJvmHeapSize=null;
String maxJvmHeapSize=null;
String debugPort = null;
HashMap<String, String> executionGroupParameter = new HashMap<String, String>();
try {
maxJvmHeapSize = aEgProxyObj.getRuntimeProperty("ComIbmJVMManager/jvmMaxHeapSize");
executionGroupParameter.put("maxJvmHeapSize", maxJvmHeapSize);
minJvmHeapSize = aEgProxyObj.getRuntimeProperty("ComIbmJVMManager/jvmMinHeapSize");
executionGroupParameter.put("minJvmHeapSize", minJvmHeapSize);
debugPort = aEgProxyObj.getRuntimeProperty("ComIbmJVMManager/jvmDebugPort");
executionGroupParameter.put("debugPort", debugPort);
}
catch (ConfigManagerProxyPropertyNotInitializedException e) {
e.printStackTrace();
}
return executionGroupParameter;

Hi Rahul999,
need a clarification on the question?
Are you looking to report the jvm (min /max) parameters being set for an exgrp?
This can be obtained by mqsireportproperties command as follows:
mqsireportproperties BrokerName -e ExgrpName -o ComIbmJVMManager -a
Also, as suggested by "madhuthetom", you can use CMP API.
(OR)
Are you looking to check the value of heap size occupied by exgrp jvm at a given point (while exgrp is in running state)?
There may not be any broker commands or API to provide the information of jvm size occupied by an exgrp at a given point.
option1) set the following in broker profile or so...
export MQSIJVERBOSE=-verbose:gc
This way, broker publishes an xml msg with details of exgrp jvm.
We have seen that, it only publishes, when the exgrp starts up, not after that (ie: not periodically or so..)
option2) Probably you can explore on topic "JVM profiling"
There may be tools (or app), which can connect to JVMDebugPort of an exgrp to query jvm value at a given point.
