Usage notes
- On UNIX systems, the command is valid only on AIX®, HP-UX, Linux, and Solaris.
- On z/OS, the command fails if the channel initiator is not started.
Parameter descriptions for DISPLAY CLUSQMGR
- (generic-qmgr-name)
- The name of the cluster queue manager for which information
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
- 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 CT 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 EX 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 CTG 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 EXG 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, filter-value 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. If the attribute value is a value from a possible set of values, you can use only EQ or NE. For example, the value
STARTING
on theSTATUS
parameter. - A generic value. filter-value is a character
string. An example is
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. Only a single trailing wildcard character (asterisk) is permitted.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 isDEF
are listed. If it is generic, use CTG or EXG as the operator. IfABC*
is specified with the operator CTG, all items where one of the attribute values begins withABC
are listed.
- An explicit value, that is a valid value for the attribute being
tested.
- ALL
- Specify ALL 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.
ALL is the default if you do not specify a generic name and do not request any specific parameters.
On z/OS ALL is also the default if you specify a filter condition using the WHERE parameter, but on other platforms, only requested attributes are displayed.
- 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. '' 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. You can enter a different queue manager name, 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 * 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.

the local queue manager, in the form
yyyy-mm-dd

- QMTYPE
- The function
of the cluster queue manager in the cluster:
