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.
Specifies the disposition of the channels to be started.
The value can be:
A sending channel is private if its transmission queue has a disposition other than MQQSGD_SHARED.
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 13
ChannelDisposition | CommandScope blank or local-qmgr | CommandScope qmgr-name | CommandScope(*) |
---|---|---|---|
MQCHLD_PRIVATE | Start as a private channel on the local queue manager | Start as a private channel on the named queue manager | Start as a private channel on all active queue managers |
MQCHLD_SHARED | For channels of ChannelType MQCHT_SENDER,
MQCHT_REQUESTER, and MQCHT_SERVER, start as a shared channel on the most suitable
queue manager in the group.
For a shared channel of ChannelType MQCHT_RECEIVER and MQCHT_SVRCONN, start the channel on all active queue managers. For a shared channel of ChannelType MQCHT_CLUSSDR and MQCHT_CLUSRCVR, this option is not permitted. 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. |

MQCHLD_FIXSHARED | For a shared channel of ChannelType MQCHT_SENDER, MQCHT_REQUESTER, and MQCHT_SERVER, with a nonblank ConnectionName, start as a shared channel on the local queue manager. | For a shared channel of ChannelType MQCHT_SENDER, MQCHT_REQUESTER, and MQCHT_SERVER, with a nonblank ConnectionName, start as a shared channel on the named queue manager. | Not permitted |
