    I know there is at least one on STW, actually 🙂

    No but we have them at work… Got a specific question?

    My file input node was reading messages just fine, but now it just does nothing until I restart the broker at which point it reads the message.

    Confused I am.

    Ahem 😉

    What polling interval do you have set ? Node Properties->Polling

    Five seconds. I think I fixed it now.. Deleted the temporary files in the transition directory, restarted and it works.

    Do you by any chance know about setting java system properties with mqsichangeproperties? I set some but they don’t seem to have the desired effect and when I call System.getProperties they aren’t there, despite being visible with mqsireportproperties.

    Presumably you tried:-

    mqsichangeproperties <BKR> -o ComIbmJVMManager -n jvmSystemProperty -v -Dpropname=propvalue

    (might need to specify a -e <execution group> arg if you want to target Java Compute nodes in a specific execution group)

    Oh, did you restart broker after the mqsichangeproperties command ?

    Yes and yes. Reportpropeties DID show correct properties, but the jvm didn’t seem to want to know.

    Hmmm, I have had success previously with setting JVM properties using the command. What version / platform ?

    Personally I think you’re wrong
    You need to reset the whatchamacallit so the thingmagig can talk to the oojimaflop – that should sort it

    What I’m trying to do is allow remote JMX connections to the JVM for the broker (or is it the execution group?)

    That’s normally done with JVM properties. Like I say mqsireportproperties reports them correctly but if I write Java code to list them out they aren’t there.
