Air Cleaner User Manual

This parameter is valid only for channels with a channel type (CHLTYPE)
of RCVR, RQSTR, or CLUSRCVR. It is not supported on OS/390.
MRTMR(integer)
The minimum interval of time that must pass before the channel can retry
the MQPUT operation. This time interval is in milliseconds.
This parameter controls the action of the MCA only if the message-retry
exit name is blank. If the exit name is not blank, the value of MRTMR is
passed to the exit for the exit’s use, but the retry interval is controlled by
the exit, and not by this parameter.
The value must be greater than or equal to zero, and less than or equal to
999 999 999. A value of zero means that the retry will be performed as
soon as possible (provided that the value of MRRTY is greater than zero).
This parameter is valid only for channels with a channel type (CHLTYPE)
of RCVR, RQSTR, or CLUSRCVR. It is not supported on OS/390.
MSGDATA(string)
User data for the channel message exit (maximum length 32 characters).
This data is passed to the channel message exit when it is called.
On AIX, HP-UX, OS/2 Warp, Sun Solaris, and Windows NT, you can
specify data for more than one exit program by specifying multiple strings
separated by commas. The total length of the field must not exceed 999
characters.
On OS/400, you can specify up to 10 strings, each of length 32 characters.
The first string of data is passed to the first message exit specified, the
second string to the second exit, and so on.
On other platforms you can specify only one string of message exit data
for each channel.
MSGEXIT(string)
Channel message exit name.
On Tandem NSK, there is only one channel user exit program. If the
MSGEXIT, MREXIT, SCYEXIT, SENDEXIT, and RCVEXIT parameters are
all left blank, the channel user exit is not invoked. If any of these
parameters is nonblank, the channel exit program is called. You can enter
text string for these parameters. The maximum length of the string is 128
characters. This string is passed to the exit program, but it is not used to
determine the program name.
See the MQSeries for Tandem NonStop Kernel System Management Guide for
more information about using channel exit programs on Tandem NSK.
On other platforms, if this name is nonblank, the exit is called at the
following times:
v Immediately after a message has been retrieved from the transmission
queue (sender or server), or immediately before a message is put to a
destination queue (receiver or requester).
The exit is given the entire application message and transmission queue
header for modification.
v At initialization and termination of the channel.
