runmqdlq (run dead-letter queue handler)
Purpose
Use the runmqdlq command to start the dead-letter queue (DLQ) handler, which monitors and handles messages on a dead-letter queue.
Syntax
>>-runmqdlq--+-------------------------+----------------------->< '- QName --+------------+-' '- QMgrName -'
Description
Use the dead-letter queue handler to perform various actions on selected messages by specifying a set of rules that can both select a message and define the action to be performed on that message.
The runmqdlq command takes its input from stdin. When the command is processed, the results and a summary are put into a report that is sent to stdout.
By taking stdin from the keyboard, we can enter runmqdlq rules interactively.
By redirecting the input from a file, we can apply a rules table to the specified queue. The rules table must contain at least one rule.
If you use the DLQ handler without redirecting stdin from a file (the rules table), the DLQ handler reads its input from the keyboard. In WebSphere MQ for AIX, Solaris, HP-UX, and Linux, the DLQ handler does not start to process the named queue until it receives an end_of_file (Ctrl+D) character. In WebSphere MQ for Windows, it does not start to process the named queue until you press the following sequence of keys: Ctrl+Z, Enter, Ctrl+Z, Enter.
For more information about rules tables and how to construct them, see The DLQ handler rules table.
Optional parameters
The MQSC command rules for comment lines and for joining lines also apply to the DLQ handler input parameters.
- QName
- The name of the queue to be processed.
If you omit the name, the dead-letter queue defined for the local queue manager is used. If you enter one or more blanks (' '), the dead-letter queue of the local queue manager is explicitly assigned.
- QMgrName
- The name of the queue manager that owns the queue to be processed.
If you omit the name, the default queue manager for the installation is used. If you enter one or more blanks (' '), the default queue manager for this installation is explicitly assigned.
