DISCARD TDQUEUE

Remove a transient data queue definition.

Syntax

Warning: System commands are powerful as they provide information about the state of the system and allow changes to be made to it. System commands should be used only by authorized applications and users.

Activate security checks on commands by specifying the XCMD system initialization parameter and by ensuring that command security checking is active for the transaction (either by specifying CMDSEC(YES) on the TRANSACTION resource definition or by specifying ALWAYS on the CMDSEC system initialization parameter).

NOHANDLE, RESP, and RESP2 are common options that can be added to all EXEC CICS commands to process error conditions. They are not explicitly included in the command syntax diagram and option descriptions. For information about these common options and EXEC CICS command syntax, see EXEC CICS command format and programming considerations.

This command is threadsafe.

Description

The DISCARD TDQUEUE command removes the definition of a transient data queue from the local CICS® system.

A queue must be disabled before it can be discarded, and an extrapartition queue must be closed as well. See Discarding resource definitions for rules governing disabling of queues. Queues required by CICS (those whose names begin with the letter C) cannot be discarded.

When an intrapartition queue is discarded, an implicit DELETEQ command is executed to empty the queue and release space in the data set associated with it. If the queue is defined as logically recoverable, an implicit SYNCPOINT command follows the DELETEQ. The SYNCPOINT commits all changes to recoverable resources made up to that point in the task that issued the DISCARD TDQUEUE command. However, deletion and syncpoint take place only if the command completes successfully, without raising any exception conditions.

See Discarding resource definitions for general information about discards.
