Channel Data attributes

The Channel Data attributes provide detailed information about a channel.

Alter Date & Time The date and time that channel definition is last altered.

Batch Size The maximum number of messages that this channel processes before a checkpoint is taken; that is, the size of logical unit of work (LUW) of this channel. The valid format is an integer, in the range 0 - 9999.

Channel Description The description of this channel. This attribute is not available for CICS channels. The valid format is an alphanumeric string of up to 256 case-sensitive characters.

Channel Name The name of this channel. The valid format is an alphanumeric string of up to 20 case-sensitive characters.

Channel Type The type that is assigned to the channel (SDR for sender, SVR for server, RCVR for receiver, RQSTR for requester, CLNTCONN for client connection, SVRCONN for server connection, CLUSRCVR for cluster receiver, CLUSSDR for cluster sender, ClusQmgr for cluster queue manager) when it is created. Valid values are as follows:

  • n/a = 0
  • SDR = 1
  • SVR = 2
  • RCVR = 3
  • RQSTR = 4
  • CLNTCONN = 6
  • SVRCONN = 7
  • CLUSRCVR = 8
  • CLUSSDR = 9
  • MQCHT_MQTT = 10
  • ClusQmgr = 254

Cluster The name of the cluster that the channel belongs to. The valid format is an alphanumeric string of up to 48 case-sensitive characters.

Cluster Channel Definition Type Indicates how this channel is defined. Valid format is an integer. Valid values are as follows:

  • Explicit_Cluster-Sender = 1
  • Automatic_Cluster-Sender = 2
  • Explicit_Cluster-Receiver = 3
  • Explicit/Auto_Cluster-Sender = 4
  • n/a = 255

Cluster Date & Time The date and time that this cluster channel definition is made available.

Cluster Namelist The name of the namelist that specifies a list of clusters that the channel belongs to. The valid format is an alphanumeric string of up to 48 case-sensitive characters.

Cluster QMgr The name of the cluster queue manager. The valid format is an alphanumeric string of up to 48 case-sensitive characters.

Cluster QMgr Suspend Indicates whether the cluster queue manager is suspended. Valid values are No = 0, Yes = 1, and n/a = 255.

Cluster QMgr Type The function of the associated queue manager in the cluster. The valid format is an integer. Valid values are Normal = 0, Repository = 1, and n/a = 255.

Connection Name The name of the physical or logical connection that this channel uses to transmit or receive data. This name is formed from the connection type (IP for TCP/IP, LU for LU6.2, or NETBIOS) and the connection address. Valid format is an alphanumeric string of up to 264 case-sensitive characters. If multiple connections are configured for the channel, this attribute is displayed as a comma separated list of names of systems for the stated Transport Type attribute.

Host Name The name of the system on which this queue manager is running. On z/OS systems, this is the SMF ID. The valid format is an alphanumeric string of up to 48 case-sensitive characters.

Maximum Msg Len The longest message length that this channel can accommodate. The length must be less than or equal to 104857600. Zero indicates that the channel uses the same maximum message length as the queue manager that it belongs to. The valid format is an integer, in the range 0 - 104857600.

Origin Node The IBM MQ Monitoring agent-assigned name of the node on which the data for the queue manager originates.

On z/OS, this name takes the form qmgr:smfid:MQESA, where qmgr is the name of the queue manager and smfid is the z/OS system ID or SMF ID.

On distributed systems, this name takes the form qmgr::MQ. If the host ID value is specified by the SET AGENT command, this name takes the form qmgr:hostid:MQ. The valid format is an alphanumeric string of up to 128 case-sensitive characters.

QMgr Name The name that is assigned to this queue manager. The valid format is an alphanumeric string of up to 48 case-sensitive characters.

QSG Disp Disposition in the queue sharing group. Valid values are Qmgr = 0, Copy = 1, Group = 3, and Unknown = 255. This attribute is for QSG environment on z/OS systems only.

QSG Name The name of the queue sharing group. The valid format is an alphanumeric string of up to 4 case-sensitive characters. This attribute is for QSG environment on z/OS systems only.

Transport Type The transmission type (LU62, TCP for TCP/IP, NETBIOS, or CICS). Valid values are as follows:

  • LOCAL = 0
  • LU62 = 1
  • TCP = 2
  • NETBIOS = 3
  • SPX = 4
  • DECNET = 5
  • UDP = 6
  • CICS = 100

XmitQ Name The name of the transmission queue for the channel. The valid format is an alphanumeric string of up to 48 case-sensitive characters.
