Hi
I have an application that needs to be dynamically opened and closed via an MQ message. I have a cron job that will open the app and will get a return message containing a session id which will sit on a queue until I am ready to close the app.
Another cron job will close the app, but it needs the session id to do this. Is it possible to access, (using ESQL), the stored message from within a flow and retrieve the data?
I am just curious if there is an altenative to storing the data in a DB.
I am on V2.1 CSD 06. |

It sounds like you need to rethink your entire design.

Thanks for the reply Jeff.
Unfortunately much of the design for this project is out of my control.
The reality is that I need to use a session ID which I have been sent 20 hours previously.
I am simply invstigating whther it is possible to interrogate a queue from within a flow rather than write the sessionID to a database.

There is an MQGet support pack node. It supplies a custom node that will retrieve messages from a queue and insert them into the message tree where information can be manipulated using ESQL.
It is currently withdrawn, because it is not immediately compatible with version 5.
If you search here for MQGet, you should find a link to the withdrawn support pack.

How are you communicating with your cron jobs from your Message Flows?

Hi Kiran
All the cron jobs are doing is putting a one word command on a nominated queue (eg 'Open' or 'Close').
Depending on the command I will attempt to retrieve the session ID stored on another queue (or from the database). |
