Hi all
Is there a limit to the number of if ..else statements that WMQI can handle ? I am using a complex sequence which goes 4 levels deep. This seems to confuse the broker no end ......
Regards

Hi,
Could you post the ESQL that you are using? When you say confuse the broker to no end, do you get any errors in the event viewer? Does nothing happen? Do you loop? What exactly is happening?

Hi there
When putting a message on the input queue, it vanishes ! There is no mention in the event viewer, trace files, or usertrace. It is just gone !
When I use a message without the statements in Integrator, it goes thru perfectly. It is really bizarre !!
I have had the esql checked by someone here who agrees with me that it is correct. It is also rather too long to post all here !
Regards

| if not already done, try attaching an Exception message builder and an output node to the catch node of the input. As to the message, it is probably on the DEAD LETTER queue, unless of course you don't have one defined then it will have been vapourised. |

Hi,
What version of WMQI are you using? I have had instances where this happens to me. The message doesn't go to the dead letter queue and no messages appear in the event viewer. Usually in these cases something is wrong with my ESQL code and it's not getting flagged as an error. Have you tried putting a trace on the message flow to see exactly what's happening. In these cases I usually can find the problem.

In addition to what is mentioned above, you may loose a message if you don't have terminals connected. In this case, no error will be logged into Event viwer.
For some reason if your messageflow is looping, it will not pickup next message on the input queue. Could you post your ESQL code here?
