The parameter descriptions also apply to the ALTER NAMELIST command, with the following exceptions:
The name must not be the same as any other namelist name currently defined on this queue manager (unless REPLACE or ALTER is specified). See Rules for naming WebSphere MQ objects.
CMDSCOPE must be blank, or the local queue manager, if QSGDISP is set to GROUP.
You can specify a queue manager name other than the queue manager on which it was entered, only if you are using a shared queue environment and if the command server is enabled.
It should contain only displayable characters. The maximum length is 64 characters. In a DBCS installation, it can contain DBCS characters (subject to a maximum length of 64 bytes).
This parameter applies only to the DEFINE NAMELIST command
If this field is not filled in, and you do not complete the parameter fields related to the command, the values are taken from the default definition for namelists on this queue manager.
This is equivalent to specifying:
LIKE(SYSTEM.DEFAULT.NAMELIST)
A default namelist definition is provided, but it can be altered by the installation to the default values required. See Rules for naming WebSphere MQ objects.
On z/OS, the queue manager searches page set zero for an object with the name you specify and a disposition of QMGR or COPY. The disposition of the LIKE object is not copied to the object you are defining.
The names can be of any type, but must conform to the rules for naming WebSphere MQ objects, with a maximum length of 48 characters.
An empty list is valid: specify NAMES(). The maximum number of names in the list is 256.
This parameter is valid only on z/OS.
Namelists used for clustering must have NLTYPE(CLUSTER) or NLTYPE(NONE).
Namelists used for SSL must have NLTYPE(AUTHINFO).
Specifies the disposition of the object to which you are applying the command (that is, where it is defined and how it behaves).
QSGDISP | ALTER | DEFINE |
---|---|---|
COPY | The object definition resides on the page set of the queue manager that executes the command. The object was defined using a command that had the parameters QSGDISP(COPY). Any object residing in the shared repository, or any object defined using a command that had the parameters QSGDISP(QMGR), is not affected by this command. | The object is defined on the page set of the queue manager that executes the command using the QSGDISP(GROUP) object of the same name as the 'LIKE' object. |
GROUP | The object definition resides in the shared repository.
The object was defined using a command that had the parameters QSGDISP(GROUP).
Any object residing on the page set of the queue manager that executes the
command (except a local copy of the object) is not affected by this command.
If the command is successful, the following command is generated and sent to all active queue managers in the queue-sharing group to attempt to refresh local copies on page set zero: DEFINE NAMELIST(name) REPLACE QSGDISP(COPY)The ALTER for the group object takes effect regardless of whether the generated command with QSGDISP(COPY) fails. |
The object definition resides in the shared repository.
This is allowed only if the queue manager is in a queue-sharing group.
If the definition is successful, the following command is generated and sent to all active queue managers in the queue-sharing group to attempt to make or refresh local copies on page set zero: DEFINE NAMELIST(name) REPLACE QSGDISP(COPY)The DEFINE for the group object takes effect regardless of whether the generated command with QSGDISP(COPY) fails. |
PRIVATE | The object resides on the page set of the queue manager
that executes the command, and was defined with QSGDISP(QMGR) or QSGDISP(COPY).
Any object residing in the shared repository is unaffected. |
Not permitted. |
QMGR | The object definition resides on the page set of the queue
manager that executes the command. The object was defined using a command
that had the parameters QSGDISP(QMGR). Any object residing in the shared repository,
or any local copy of such an object, is not affected by this command.
This is the default value. |
The object is defined on the page set of the queue manager
that executes the command.
This is the default value. |
This parameter applies only to the DEFINE NAMELIST command
