Invoking the DLQ handler

The CSQUDLQH utility program runs as a z/OS batch program. Specify the name of the dead-letter queue that you want to process and the queue manager on which it resides. We can do this in one of the following two ways (in these examples, the dead-letter queue is called CSQ1.DEAD.QUEUE and the queue manager is called CSQ1):

1. The names can be specified as positional parameters in the PARM parameter of the EXEC statement within the submitted JCL, for example:
   Figure 78. Specifying the queue manager and dead-letter queue names for the dead-letter queue handler in the JCL

   //READQ EXEC PGM=CSQUDLQH,
   //  PARM='CSQ1.DEAD.QUEUE CSQ1'

2. The names can be specified in the rules table, for example:
   Figure 79. Specifying the queue manager and dead-letter queue names for the dead-letter queue handler in the rules table

   INPUTQ(CSQ1.DEAD.QUEUE) INPUTQM(CSQ1)

Any parameters that you specify in the PARM parameter override those in the rules table. If you specify only one parameter in the PARM statement, this is used as the name of the dead-letter queue. The rules table is taken from the SYSIN data set.
