Description: The maximum number of bytes allowed in individual messages on this SAF agent. The message size includes the message body, any user-defined properties, and the user-defined JMS header fields: JMSCorrelationID and JMSType. Producers sending messages that exceed the configured maximum message size for the SAF agent will receive a ResourceAllocationException. 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. Applies only to agents with sending capability. Updating MaximumMessageSize affects only incoming messages; stored messages are not affected.
