2.3.4.76 Automatic defragmentation of message/partial messages (defragment, nodefragment)

The MIME standard provides the message/partial content type for breaking up messages into smaller parts. This is useful when messages have to traverse networks with size limits. Information is included in each part so that the message can be automatically reassembled once it arrives at its destination.

The defragment channel keyword and the defragmentation channel provide the means to reassemble messages in PMDF. When a channel is marked defragment any message/partial messages queued to the channel will be placed in the defragmentation channel queue instead. Once all the parts have arrived the message is rebuilt and sent on its way.

The nodefragment disables this special processing. nodefragment is the default.

A defragment channel must be added to the PMDF configuration file in order for the defragment keyword to have any effect. If your configuration was built by the PMDF configuration utility, then you should already have such a channel. If not consult Section 28.3.
