Optional parameters

CommandScope (MQCFST)
Command scope (parameter identifier: MQCACF_COMMAND_SCOPE). This parameter applies to z/OS only.

Specifies how the command is executed when the queue manager is a member of a queue-sharing group. You can specify one of the following:

The maximum length is MQ_QSG_NAME_LENGTH.

ChannelDisposition (MQCFIN)
Channel disposition (parameter identifier: MQIACH_CHANNEL_DISP). This parameter applies to z/OS only.

Specifies the disposition of the channels to be resolved.

The value can be:

MQCHLD_PRIVATE
A receiving channel is private if it was started in response to an inbound transmission directed to the queue manager.

A sending channel is private if its transmission queue has a disposition other than MQQSGD_SHARED.

MQCHLD_SHARED
A receiving channel is shared if it was started in response to an inbound transmission directed to the queue-sharing group.

A sending channel is shared if its transmission queue has a disposition of MQQSGD_SHARED.

The combination of the ChannelDisposition and CommandScope parameters also controls from which queue manager the channel is operated. The possible options are:

The various combinations of ChannelDisposition and CommandScope are summarized in Table 12

Table 12. ChannelDisposition and CommandScope for RESOLVE CHANNEL
ChannelDisposition CommandScope blank or local-qmgr CommandScope qmgr-name
MQCHLD_PRIVATE Resolve private channel on the local queue manager Resolve private channel on the named queue manager
MQCHLD_SHARED Resolve a shared channel on all active queue managers.

This might automatically generate a command using CommandScope and send it to the appropriate queue manager. If there is no definition for the channel on the queue manager to which the command is sent, or if the definition is unsuitable for the command, the command fails.

The definition of a channel on the queue manager where the command is entered might be used to determine the target queue manager where the command is actually run. Therefore, it is important that channel definitions are consistent. Inconsistent channel definitions might result in unexpected command behavior.
