Trying to launch MQPerf on an Oracle T4-4 server (Solaris), I get this error
$ java -jar MQPerf_v1-0-0.jar
[test1] Invalid maximum heap size: -Xmx68585259008
[test1] The specified size exceeds the maximum representable size.
[test1] Could not create the Java virtual machine.
java -Xmx3g doesn’t help, neither does java -d64

First, the Xmx3g parameter is not taken into account, as MQperf sets its own Xmx parameter value for tests, based on physical memory as read by JMX. The value given in your error message let us think you have a (very) large amount of memory on your server. Can you confirm that?
Also, there is a limitation (due to java) on the size of the Xmx parameter value. Notice that this limitation is system dependent, and we did not anticipate such an error.
Finally, we’re working on a fix and are confident to provide soon a new release of MQperf solving this issue.

We have pushed a new probe, MQPerf_v1-1-1.jar.
Can you please check it and let us know if the problem is fixed ?
