Parameter descriptions

 

You must specify the name of the process you want to display. This can be a specific process name or a generic process name. By using a generic process name, we can display either:

(generic-process-name)

The name of the process definition to be displayed (see Rules for naming WebSphere MQ objects). A trailing asterisk (*) matches all processes with the specified stem followed by zero or more characters. An asterisk (*) on its own specifies all processes. The names must all be defined to the local queue manager.

WHERE

Specify a filter condition to display only those process definitions 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, we cannot use the CMDSCOPE or QSGDISP parameters as filter keywords.

operator

This is used to determine whether a process definition 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

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 DEF on the APPLTYPE parameter), we 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*. 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.

ALL

Specify this to display all the parameters. If this parameter is specified, any parameters that are requested specifically have no effect; all parameters are still displayed.

On AIX, HP OpenVMS, HP-UX, Linux, i5/OS, Solaris, Windows, and z/OS, this is the default if you do not specify a generic name and do not request any specific parameters.

On Compaq NonStop Kernel, if no parameters are specified (and the ALL parameter is not specified), the default is that the process names are returned.

On z/OS this is also the default if you specify a filter condition using the WHERE parameter, but on other platforms only requested attributes are displayed.

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.

CMDSCOPE must be blank, or the local queue manager, if QSGDISP is set to 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.

We 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.

We cannot use CMDSCOPE as a filter keyword.

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(LIVE) is specified or defaulted, or if QSGDISP(ALL) is specified in a shared queue manager environment, the command might give duplicated names (with different dispositions).

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).

We cannot use QSGDISP as a filter keyword.
