Parameter descriptions

(generic-qmgr-name)
The name of the cluster queue manager for which informaiton is to be displayed.

A trailing asterisk (*) matches all cluster queue managers with the specified stem followed by zero or more characters. An asterisk (*) on its own specifies all cluster queue managers.

WHERE
Specify a filter condition to display only those cluster channels that satisfy the selection criterion of the filter condition. The filter condition is in three parts: filter-keyword, operator, and filter-value:
filter-keyword
Almost any parameter that can be used to display attributes for this DISPLAY command. However, you cannot use the CMDSCOPE or MCANAME parameters as filter keywords. You cannot use CHANNEL or CLUSTER as filter keywords if you use them to select cluster queue managers.
operator
This is used to determine whether a cluster channel satisfies the filter value on the given filter keyword. The operators are:
LT
Less than
GT
Greater than
EQ
Equal to
NE
Not equal to
LE
Less than or equal to
GE
Greater than or equal to
LK
Matches a generic string that you provide as a filter-value
NL
Does not match a generic string that you provide as a filter-value
CT
Contains a specified item. If the filter-keyword is a list, you can use this to display objects the attributes of which contain the specified item.
EX
Does not contain a specified item. If the filter-keyword is a list, you can use this to display objects the attributes of which do not contain the specified item.
CTG
Contains an item which matches a generic string that you provide as a filter-value. If the filter-keyword is a list, you can use this to display objects the attributes of which match the generic string.
EXG
Does not contain any item which matches a generic string that you provide as a filter-value. If the filter-keyword is a list, you can use this to display objects the attributes of which do not match the generic string.
filter-value
The value that the attribute value must be tested against using the operator. Depending on the filter-keyword, this can be:
  • An explicit value, that is a valid value for the attribute being tested.

    You can use operators LT, GT, EQ, NE, LE or GE only. However, if the attribute value is one from a possible set of values on a parameter (for example, the value STARTING on the STATUS parameter), you can only use EQ or NE.

  • A generic value. This is a character string (such as the character string you supply for the CONNAME parameter) with an asterisk at the end, for example ABC*. If the operator is LK, all items where the attribute value begins with the string (ABC in the example) are listed. If the operator is NL, all items where the attribute value does not begin with the string are listed.

    You cannot use a generic filter-value for parameters with numeric values or with one of a set of values.

  • An item in a list of values. The value can be explicit or, if it is a character value, it can be explicit or generic. If it is explicit, use CT or EX as the operator. For example, if the value DEF is specified with the operator CT, all items where one of the attribute values is DEF are listed. If it is generic, use CTG or EXG as the operator. If ABC* is specified with the operator CTG, all items where one of the attribute values begins with ABC are listed.
ALL
Specify this to display all the parameters. If this parameter is specified, any parameters that are also requested specifically have no effect; all parameters are still displayed. This is the default if you do not specify a generic name and do not request any specific parameters.
CHANNEL(generic-name)
This is optional, and limits the information displayed to cluster channels with the specified channel name. The value can be a generic name.
CLUSTER(generic-name)
This is optional, and limits the information displayed to cluster queue managers with the specified cluster name. The value can be a generic name.
CMDSCOPE
This parameter applies to z/OS only and specifies how the command is executed when the queue manager is a member of a queue-sharing group.

' '
The command is executed on the queue manager on which it was entered. This is the default value.
qmgr-name
The command is executed on the queue manager you specify, providing the queue manager is active within the queue-sharing group.

You can specify a queue manager name, other than the queue manager on which the command was entered, only if you are using a queue-sharing group environment and if the command server is enabled.

*
The command is executed on the local queue manager and is also passed to every active queue manager in the queue-sharing group. The effect of this is the same as entering the command on every queue manager in the queue-sharing group.

You cannot use CMDSCOPE as a filter keyword.

Requested parameters

Specify one or more parameters that define the data to be displayed. The parameters can be specified in any order, but do not specify the same parameter more than once.

Some parameters are relevant only for cluster channels of a particular type or types. Attributes that are not relevant for a particular type of channel cause no output, and do not cause an error.

CLUSDATE
The date on which the definition became available to the local queue manager, in the form yyyy-mm-dd.
CLUSTIME
The time at which the definition became available to the local queue manager, in the form hh.mm.ss.
DEFTYPE
How the cluster channel was defined:
CLUSSDR
As a cluster-sender channel from an explicit definition.
CLUSSDRA
As a cluster-sender channel by auto-definition alone.
CLUSSDRB
As a cluster-sender channel by auto-definition and an explicit definition.
CLUSRCVR
As a cluster-receiver channel from an explicit definition.
QMID
The internally generated unique name of the cluster queue manager.
QMTYPE
The function of the cluster queue manager in the cluster:
REPOS
Provides a full repository service.
NORMAL
Does not provide a full repository service.
STATUS
The current status of the channel for this cluster queue manager. This is one of the following:
STARTING
A request has been made to start the channel but the channel has not yet begun processing. A channel is in this state if it is waiting to become active.
BINDING
The channel is performing channel negotiation and is not yet ready to transfer messages.
INACTIVE
The channel is not active.
INITIALIZING
The channel initiator is attempting to start a channel. On z/OS, this is displayed as INITIALIZI.
RUNNING
The channel is either transferring messages at this moment, or is waiting for messages to arrive on the transmission queue so that they can be transferred.
STOPPING
The channel is stopping, or a close request has been received.
RETRYING
A previous attempt to establish a connection has failed. The MCA will reattempt connection after the specified time interval.
PAUSED
The channel is waiting for the message-retry interval to complete before retrying an MQPUT operation.
STOPPED
This state can be caused by one of the following:
  • Channel manually stopped.

    A user has entered a stop channel command against this channel.

  • Retry limit reached.

    The MCA has reached the limit of retry attempts at establishing a connection. No further attempt is made to establish a connection automatically.

A channel in this state can be restarted only by issuing the START CHANNEL command, or starting the MCA program in an operating-system dependent manner.

REQUESTING
A local requester channel is requesting services from a remote MCA.
SUSPEND
Whether this cluster queue manager is suspended from the cluster or not (as a result of the SUSPEND QMGR command). This is either YES or NO.
