Parameter descriptions
You must specify the name of the namelist definition you want to display.
This can be a specific namelist name or a generic namelist name. By using
a generic namelist name, you can display either:
- All namelist definitions
- One or more namelists that match the specified name
- (generic-namelist-name)
- The name of the namelist definition to be displayed (see Rules for naming WebSphere MQ objects).
A trailing asterisk (*) matches all namelists with the specified
stem followed by zero or more characters. An asterisk (*) on its
own specifies all namelists.
- WHERE
- Specify a filter condition to display only those namelists 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 QSGDISP parameters
as filter keywords. You cannot use NLTYPE
as a filter keyword if you also use it to select namelists.
- operator
- This is used to determine whether a namelist 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 NONE on the NLTYPE 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 DESCR parameter) with an asterisk at the end, for example
ABC*. The characters must be valid for the attribute you are testing.
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 requested specifically have no effect; all the parameters
are displayed.
This is the default if you do not specify a generic name,
and do not request any specific parameters.
- CMDSCOPE
- This parameter 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.
- QSGDISP
- Specifies the disposition of the objects for which information is to
be displayed. Values are:
- LIVE
- This is the default value and displays information for objects defined
with QSGDISP(QMGR) or QSGDISP(COPY).
- ALL
- Displays information for objects defined with QSGDISP(QMGR) or QSGDISP(COPY).
If there is a shared queue manager environment, and the command is being executed
on the queue manager where it was issued, this option also displays information
for objects defined with QSGDISP(GROUP).
If QSGDISP(ALL) is specified
in a shared queue manager environment, the command might give duplicated names
(with different dispositions).
In a shared queue manager environment,
use
DISPLAY NAMELIST(name) CMDSCOPE(*) QSGDISP(ALL)
to list
ALL objects matching
name
in the queue-sharing group without duplicating
those in the shared repository.
- COPY
- Display information only for objects defined with QSGDISP(COPY).
- GROUP
- Display information only for objects defined with QSGDISP(GROUP). This
is allowed only if there is a shared queue manager environment.
- PRIVATE
- Display information for objects defined with QSGDISP(QMGR) or QSGDISP(COPY).
Note that QSGDISP(PRIVATE) displays the same information as QSGDISP(LIVE).
- QMGR
- Display information only for objects defined with QSGDISP(QMGR).
QSGDISP displays one of the following values:
- QMGR
- The object was defined with QSGDISP(QMGR).
- GROUP
- The object was defined with QSGDISP(GROUP).
- COPY
- The object was defined with QSGDISP(COPY).
You cannot use QSGDISP as a filter
keyword.
- NLTYPE
- Indicates the type of namelist to be displayed.
This parameter is
valid only on z/OS.
- ALL
- Displays namelists of all types. This is the default.
- NONE
- Displays namelists of type NONE.
- QUEUE or Q
- Displays namelists that hold lists of queue names.
- CLUSTER
- Displays namelists that are associated with clustering.
- AUTHINFO
- Displays namelists that contain lists of authentication information
object names.
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 default, if no parameters are specified (and the ALL parameter is not
specified) is that the object names, and, on z/OS, their NLTYPEs and QSGDISP
are displayed.
- ALTDATE
- The date on which the definition was last altered, in the form yyyy-mm-dd
- ALTTIME
- The time at which the definition was last altered, in the form hh.mm.ss
- DESCR
- Description
- NAMCOUNT
- Number of names in the list
- NAMES
- List of names
See DEFINE NAMELIST for more information about the individual parameters.
