MAXMSGL(integer)
Specifies the maximum message length that can be transmitted on the
channel. This is compared with the value for the partner and the actual
maximum used is the lower of the two values.
The value zero means the maximum message length for the queue
manager.
On AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, and Windows NT,
specify a value greater than or equal to zero, and less than or equal to the
maximum message length for the queue manager.
See the MAXMSGL parameter of the ALTER QMGR command for more
information.
On OS/390, specify a value greater than or equal to zero, and less than or
equal to (100 MB).
On other platforms, specify a value greater than or equal to zero, and less
than or equal to 4 194 304 bytes (4 MB).
MCANAME(string)
Message channel agent name.
This is reserved, and if specified must only be set to blanks (maximum
length 20 characters).
MCATYPE
Specifies whether the message-channel-agent program should run as a
thread or a process.
PROCESS
The message channel agent runs as a separate process
THREAD
The message channel agent runs as a separate thread
In situations where a threaded listener is required to service a large
number of incoming requests, resources can become strained. In this case,
it is recommended that multiple listener processes are used and that
incoming requests are targeted at specific listeners via the port number
specified on the listener.
This parameter is valid only for channels with a channel type (CHLTYPE)
of SDR, SVR, RQSTR, CLUSSDR, or CLUSRCVR. It is supported only on
AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, and Windows NT.
On OS/390 it is supported only for channels with a channel type of
CLUSRCVR. When specified in a CLUSRCVR definition, MCATYPE is
used by a remote machine to determine the corresponding CLUSSDR
definition.
MCAUSER(string)
Message channel agent user identifier.
If string is nonblank, it is the user identifier which is to be used by the
message channel agent for authorization to access MQSeries resources,
including (if PUTAUT is DEF) authorization to put the message to the
destination queue for receiver or requester channels.
If it is blank, the message channel agent uses its default user identifier.
The default user identifier is derived from the user ID that started the
receiving channel. The possible values are:
