Hi,

I am using 7.0.0.4 of Message Broker Toolkit and am experiencing extremely slow performance when debugging a message flow. By slow, I mean it takes a good 20 seconds for it to respond to simple step over command(F6).

I have tried several things:

1. Recreating my broker
2. Limiting my workspace to a minimum
3. Changing the heap size of the toolkit JVM

My flow is very simple - MQInput node, basic transformation, output to MQOutput node.

Does anyone have any ideas/suggestions on how to make the debugger usable?

Thanks,

Would this happen to be a JavaComputeNode? I have never had issues debugging when using ESQL, but I have experienced *very* slow debugging when using largish (100kb+) messages going through java compute nodes. This was at v8.0.0.1 but I expect the issue may still be there in v7.

Unfortunately no java compute node is involved... I work with a few others and most of us are experiencing the same problem.

One option would be to try upgrading to 7.0.0.5 - http://www-01.ibm.com/support/docview.wss?uid=swg27006041

Learn to use better debugging tools. The interactive debugger is the least effective tool you can use. Don't use it.

Try User Trace or putting Trace nodes in your flows.

For each step (in the debugger) the full message is transmitted. So this is obviously slow.

Though... the toolkit seems to me to work less robust on Version 7 (7.0.0.3) than on 6 (or 6.1).
