Hello,
We are trying to browse messages from a Queue using the MQGET node.
We set the OutputLocalEnvironment.MQ.GET.MGMO.Options = MQGMO_BROWSE_FIRST, but the flow throw an exception with ReasonCode=2036. The exception says that we need expicify the MQOO_BROWSE, but we don´t now if that property is especified in the MQGET node properties, in the OutputLocalEnvironment, or simply it can be especified.
Can We browse messages in a queue really?
How can we make that?
Thanks |

Which version are you using ?
In MB v 6.1 on MQGet node there is Request tab and "Browse only" option.

| I am also facing similar problem. I have set the option "Browse only" on MQGet node. Still the messages are getting consumed destructively. Do I need to set anything in LocalEnvironment before MQGet node? |

The problem is solved when MQGMO_BROWSE_FIRST is set in LocalEnvironment along with "Browse Only" option set on MQGet node as shown below:
SET OutputLocalEnvironment.MQ.GET.MQGMO.Options = MQGMO_BROWSE_FIRST
I guess "Browse Only" option on MQGet node opens the specified queue in Browse mode and the option MQGMO_BROWSE_FIRST set in LocalEnvironment is required for doing the actual browsing. |

If you clicked the "browse" button then the message won't get consumed destructively.
The MQGet node uses MQGMO_BROWSE_NEXT as it's default option. This means that the message cursor will advance each time you invoke MQGet.
If you set MQGMO_BROWSE_FIRST every time before you call MQGet, then you will always read the first message on the queue and never read any other messages.
This is basic MQ browse behavior. |
