The Delete Topic (MQCMD_DELETE_TOPIC) PCF command deletes the specified administrative topic object.

Required parameters

TopicName (MQCFST): The name of the administrative topic definition to be deleted (parameter identifier: MQCA_TOPIC_NAME).
The maximum length of the string is MQ_TOPIC_NAME_LENGTH.

Optional parameters for z/OS

CommandScope (MQCFST)

Command scope (parameter identifier: MQCACF_COMMAND_SCOPE). This parameter applies to z/OS® only.

Specifies how the command is executed when the queue manager is a member of a queue sharing group. You can specify one of the following:

blank (or omit the parameter altogether). The command is executed on the queue manager on which it was entered.
a queue manager name. The command is executed on the queue manager you specify, providing it is active within the queue sharing group. If you specify a queue manager name other than the queue manager on which it was entered, you must be using a queue sharing group environment, and the command server must be enabled.
an asterisk (*). The command is executed on the local queue manager and is also passed to every active queue manager in the queue sharing group.

The maximum length is MQ_QSG_NAME_LENGTH.

QSGDisposition (MQCFIN)

Disposition of the object within the group (parameter identifier: MQIA_QSG_DISP). This parameter applies to z/OS only.

Specifies the disposition of the object to which you are applying the command (that is, where it is defined and how it behaves). The value can be any of the following values:

MQQSGD_COPY

The object definition resides on the page set of the queue manager that executes the command. The object was defined by a command using the parameter MQQSGD_COPY. Any object residing in the shared repository, or any object defined using a command that had the parameters MQQSGD_Q_MGR, is not affected by this command.

MQQSGD_GROUP

The object definition resides in the shared repository. The object was defined by a command using the parameter MQQSGD_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 deletion is successful, the following MQSC command is generated and sent to all active queue managers in the queue sharing group to make, or delete, local copies on page set zero:


DELETE TOPIC(name) QSGDISP(COPY)

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

MQQSGD_Q_MGR

The object definition resides on the page set of the queue manager that executes the command. The object was defined by a command using the parameter MQQSGD_Q_MGR. Any object residing in the shared repository, or any local copy of such an object, is not affected by this command.

MQQSGD_Q_MGR is the default value.

Optional parameters for Multiplatforms

Authrec (MQCFIN)

Authrec (parameter identifier: MQIACF_REMOVE_AUTHREC).

Specifies whether the associated authority record is also deleted.

This parameter does not apply to z/OS.

The value can be any of the following values:

MQRAR_YES: The authority record associated with the object is deleted. This is the default.
MQRAR_NO: The authority record associated with the object is not deleted.

IgnoreState (MQCFST)

Specifies whether the command returns an error code if the object is already in the state the command would move it to (parameter identifier MQIACF_IGNORE_STATE). The value can be any of the following values:

MQIS_YES: The return code and message are the same as if the object has not been deleted.
MQIS_NO: The return code is zero, even if the object has been deleted. This is the default value.
