Synonym: DELETE STC

DELETE STGCLASS

Notes:

¹ Valid only on z/OS when the queue manager is a member of a queue sharing group.

Parameter descriptions for DELETE STGCLASS

You must specify which storage class definition you want to delete.

All queues that use this storage class must be altered to use another storage class.

(name)

The name of the storage class definition to be deleted. The name must be defined to the local queue manager.

The command fails unless all queues referencing the storage class are empty and closed.

CMDSCOPE

This parameter specifies how the command runs 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 runs on the queue manager on which it was entered. This is the default value.
qmgr-name: The command runs 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 runs 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 object to which you are applying the command (that is, where it is defined and how it behaves).

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.

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 delete local copies on page set zero:


DELETE STGCLASS(name) QSGDISP(COPY)

The deletion of the group object takes effect even if the generated command with QSGDISP(COPY) fails.

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.
