Most users have to deal with many different queue managers in their MQ environment.
If you are browsing a queue with large messages on a remote queue manager in MQ Visual Edit and have updated the “Maximum size of each message to retrieve” property on MQ Queue tab of the Preferences window to a number larger than 4MB (i.e. 4194304) then you may receive MQ reason code of 2010 when connecting to another remote queue manager.
The reason this may happen is because each channel (SVRCONN) has an attribute called MAXMSGL (maximum message length) with a default value of 4MB.
Hence, if you set MQ Visual Edit’s “Maximum size of each message to retrieve” property to a value larger than the channel’s MAXMSGL attribute then MQ will return a reason code of 2010 (MQRC_DATA_LENGTH_ERROR) when attempting to retrieve messages from a queue.
The solution is to either lower “Maximum size of each message to retrieve” property in your Preferences to 4MB or set the channel’s MAXMSGL attribute to a large number like 100MB.
Also, there is really no reason to increase MQ Visual Edit’s “Maximum size of each message to retrieve” property. If you have the property “Automatically retrieve the entire message data when opening the ‘Message Edit’ window” selected on the MQ Queue tab of the Preferences window then MQ Visual Edit will automatically get the whole message from the queue if it has already not done so.
Note: This blog posting also applies to MQ Visual Browse.
