Air Cleaner User Manual

It should contain only displayable characters. The maximum length is 64
characters. In a DBCS installation, it can contain DBCS characters (subject
to a maximum length of 64 bytes).
Note: If characters are used that are not in the coded character set
identifier (CCSID) for this queue manager, they might be translated
incorrectly if the information is sent to another queue manager.
DISCINT(integer)
The minimum time in seconds for which the channel waits for a message
to arrive on the transmission queue, after a batch ends, before terminating
the channel. A value of zero causes the message channel agent to wait
indefinitely.
The value must be greater than or equal to zero, and less than or equal to
999 999.
This parameter is valid only for channels with a channel type (CHLTYPE)
of SDR, SVR, CLUSSDR, or CLUSRCVR.
HBINT(integer)
This parameter has a different interpretation depending upon the channel
type, as follows:
v For a channel type of SDR, SVR, RCVR, RQSTR, CLUSSDR, or
CLUSRCVR, this is the time, in seconds, between heartbeat flows passed
from the sending MCA when there are no messages on the transmission
queue. The heartbeat exchange gives the receiving MCA the opportunity
to quiesce the channel.
This type of heartbeat is valid only on AIX, HP-UX, OS/2 Warp,
OS/390, OS/400, Sun Solaris, and Windows NT.
Note: You should set this value to be significantly less than the value of
DISCINT. MQSeries checks only that it is within the permitted
range however.
v For a channel type of SVRCONN or CLNTCONN, this is the time, in
seconds, between heartbeat flows passed from the server MCA when
that MCA has issued an MQGET with WAIT on behalf of a client
application. This allows the server to handle situations where the client
connection fails during an MQGET with WAIT. This type of heartbeat is
valid only for AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, and
Windows NT.
The value must be in the range zero through 999 999. A value of zero
means that no heartbeat exchange takes place. The value that is used is the
larger of the values specified at the sending side and the receiving side.
LIKE(channel-name)
The name of a channel, whose parameters will be used to model this
definition.
This parameter applies only to the DEFINE CHANNEL command.
If this field is not filled in, and you do not complete the parameter fields
related to the command, the values are taken from one of the following,
depending upon the channel type:
SYSTEM.DEF.SENDER Sender channel
SYSTEM.DEF.SERVER Server channel
SYSTEM.DEF.RECEIVER Receiver channel
SYSTEM.DEF.REQUESTER Requester channel
DEFINE CHANNEL
