<p>The maximum number of bytes allowed in individual messages on
this SAF agent.</p>
<ul>
<li>
<p>The message size includes the message body, any user-defined
properties, and the user-defined JMS header fields:
<code>JMSCorrelationID</code> and <code>JMSType</code>.</p>
</li>
<li>
<p>Producers sending messages that exceed the configured maximum
message size for the SAF agent will receive a
<code>ResourceAllocationException</code>.</p>
</li>
<li>
<p>The maximum message size is only enforced for the initial
production of a message. Messages that are redirected to an error
destination or forwarded to a member of a distributed destination
are not checked for size. For instance, if a destination and its
corresponding error destination are configured with a maximum
message size of 128K bytes and 64K bytes, respectively, a message
of 96K bytes could be redirected to the error destination (even
though it exceeds the 64K byte maximum), but a producer could not
directly send the 96K byte message to the error destination.</p>
</li>
<li>
<p>Applies only to agents with sending capability.</p>
</li>
<li>
<p>Updating <code>MaximumMessageSize</code> affects only incoming
messages; stored messages are not affected.</p>
</li>
</ul>
