Hi,
I have a flow in which we use MQGet node. Before creating the bar file we run a script which will modify the wait interval of the MQGEt node.
And whenever MQGet node timesout we throw a exception from the Throw node.
My requirement is to set the exception message text to the MQGet wait interval. I didnt find a way to retrieve the wait interval itself. Is it possible to do that?
Thanks in advance ..  |

Use this script to set the error message text at the same time as it modifies the wait interval.
The script is using mqsiapplybaroverride isn't it? The only supported way to change bar file values?

the script is called against the ".msgflow" file. and it will search for timeInterval inside that file and sets it to appropriate value as i do not wanted to make any changes in the flow. After that bar file is created.
But now i want to do add the waiting time info in the exception message. which i cannot do from that script(or it gets really complicated) as there are lot of other throw nodes also. |

Use a user defined property. Use mqsiapplybaroverrides to set this on the bar file - not the msgflow file!
Use this in your Trace node pattern.

I thought you might be doing something like this. Do not do this. Promote the property and set it in the bar file. Do not edit the msgflow with anything other than the Toolkit.
The same script which applies the change to the wait time can set a UDP, which in turn is used where you generate this message.

Basically what you people say is ...Create a UDP and use it in the flow instead of directly editng the toolkt from some script. Is my understanding correct?
In that case i agree that i will be having the access to Wait interval of MQGEt. But if i dont use UDP and simply use the MQGet node's waitInterval property can i access the value of this field in the next node.? |

You can't in general access any node properties from ESQL or Java.
The only way you might possibly be able to access this value is if it is somehow set in the output tree by the MQGet node - but I don't believe it is. I've not double-checked, though.
You can do things to set the MQGet Wait Interval before the MQGet node. You can then access the same value used to set it after the MQGet node. |
