Parameter descriptions for DELETE SUB

subscription-name

The local name of the subscription definition to be deleted.

CMDSCOPE

This parameter applies to z/OS only and 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.

You cannot use CMDSCOPE as a filter keyword.

SUBID( string )

The internal, unique key identifying a subscription.

IGNSTATE

This parameter allows you to specify whether you want the command to return an error code if the object is already in the state the command moves it to.

A value of YES means the return code and message are the same as if the MQSC object has not been deleted.

A value of NO means that the return code is zero, even if the object has been deleted. This is the default value.
