Hi,
For eg. if i have a variable
DECLARE a INT;
SET a = Cardinality(InputRoot.MRM.Lines[]);
How do i 'see' the value of a during runtime for debugging?
I've tried debugger mode but it only allows displaying before and after nodes but not what is going on within a node?
Thanks!! |

You can get the value by attaching a trace node, which writes data to a file. Following code will be used to print value of a into file.
${cardinality(Root.MRM.Lines[])}

| If you run a USERTRACE with DEBUG option on your message flow, the resulting file will show all ESQL statements, even with intermediate results. |

You can either use Trace node or USERTRACE option to get the value.
To set USERTRACE ON on your message flow,
1. Goto Operations Pannel.
2. Do a refresh of view by clicking on refresh button.
3. Right click on your message flows and select UserTrace->Debug. You will get standard dialog box.
4. Switch to log view and see if your request is processed successfully or not.
5. Come back to Operations view and press refresh button again. Now you should see "blue man" next to your message flow! This indicates that user trace on your message flow is now turned on.
6. Run your message flow by sending a message on your input queue.
7. After message is processed run command mqsireadlog and mqsiformatlog to extract user trace in a text file. Please refer to Administration Guide for more details on these commands.
Good luck!
