When trying to consume a large message from a WebLogic message queue, you may run into the above error message.
If the aggregate size of the messages pushed to a consumer is larger than the current protocol's maximum message size , the message delivery fails.
To set the maximum message size on a WebLogic client (in this case, the Boomi Atom), add the following command line property to the atom.vmoptions file:
-Dweblogic.MaxMessageSize=300000000 (this size would be based on your expected maximum message size)
A restart of the atom will be required for the new setting to take affect.
