Parameter descriptions
The parameter descriptions also apply to the ALTER CHANNEL command, with
the following exceptions:
v The LIKE parameter applies only to the DEFINE CHANNEL command.
v The REPLACE and NOREPLACE parameter applies only to the DEFINE
CHANNEL command.
v The variations in the CMDSCOPE and QSGDISP parameters between the ALTER
CHANNEL and DEFINE CHANNEL commands are described.
Parameters are optional unless the description states that they are required.
(channel-name)
The name of the new channel definition. This is required.
The name must not be the same as any existing channel defined on this
queue manager (unless REPLACE or ALTER is specified). On OS/390,
client-connection channel names can duplicate others.
The maximum length of the string is 20 characters, and the string must
contain only valid characters; see “Rules for naming MQSeries objects” on
page 4.
AUTOSTART
Specifies whether an LU 6.2 responder process for the channel will be
started at queue manager startup.
ENABLED
The responder is started.
DISABLED
The responder is not started (this is the default).
This parameter is valid only for channels with a channel type (CHLTYPE)
of RCVR, RQSTR, SVR, and SVRCONN. It is supported only on Tandem
NSK.
BATCHINT(integer)
The minimum amount of time, in milliseconds, that a channel will keep a
batch open.
The batch is terminated by whichever of the following occurs first:
v BATCHSZ messages have been sent, or
v The transmission queue is empty and BATCHINT is exceeded
The default value is zero, which means that the batch is terminated as soon
as the transmission queue becomes empty (or the BATCHSZ limit is
reached).
The value must be greater than or equal to zero, and less than or equal to
999 999 999.
This parameter is valid only for channels with a channel type (CHLTYPE)
of SDR, SVR, CLUSSDR, or CLUSRCVR. It is valid only on AIX, HP-UX,
OS/2 Warp, OS/390, OS/400, Sun Solaris, and Windows NT.
BATCHSZ(integer)
The maximum number of messages that can be sent through a channel
before taking a checkpoint.
