Plug-in with Large Messages

WebSphere MQ cannot accept an arbitrarily large message. It has restrictions based on the size of the buffers in the queue manager and its various channels. The preferred method for dealing with messages too large for the queue manager or an intermediate channel to accept is to segment the message.

The plug-in supports explicit segmentation, whereby the message is split into segments by the plug-in itself as well as automatic segmentation performed by the queue manager. See the Multi-Message tab of the Put activity for more information.

Note: Segmented messages are not supported on z/OS.
