If the Listen adapter command (
-LSN) is not issued and the message is not
available for the adapter to retrieve immediately, the map completes, but returns
the following warning in the audit log:
(2033) MQSeries Warning: No message available.
Message Buffer Size (-MBS)
Use the Message Buffer Size adapter command (-MBS) to specify the size of the
message buffer. The adapter allocates this message buffer size for retrieving
messages from a source queue. If the buffer size is insufficient, the buffer is
automatically reallocated to accommodate the messages.
-MBS
bytes
Option Description
bytes
This is the size of the message buffer in bytes. The default
buffer size is 4096 bytes.
Message Format (-FORMAT)
Use the Message Format adapter command (-FORMAT) for data targets to specify
the format of the application data in the message. Either pre-existing (defined by
IBM WebSphere MQ) or custom (user-defined) message formats can be used.
-FORMAT message_format
Option Description
message_format
A message format, either pre-existing (defined by
IBM WebSphere-MQ) or custom (user-defined). The
format can contain up to eight characters. If less
than eight, it will be padded with spaces.
For example, to specify MQFMT_STRING as the format of the message, the
following adapter command should be used:
-FORMAT MQSTR
where
MQSTR is the value of the MQFMT_STRING message format. For information
about other built-in message formats, refer to your IBM WebSphere MQ
documentation.
