The sample DLQ handler, amqsdlq

 

In addition to the DLQ handler invoked using the runmqdlq command, WebSphere MQprovides the source of a sample DLQ handler, amqsdlq, whose function is similar to that provided by runmqdlq. We can customize amqsdlq to provide a DLQ handler that meets your requirements. For example, you might decide that you want a DLQ handler that can process messages without dead-letter headers. (Both the default DLQ handler and the sample, amqsdlq, process only those messages on the DLQ that begin with a dead-letter header, MQDLH. Messages that do not begin with an MQDLH are identified as being in error, and remain on the DLQ indefinitely.)

In WebSphere MQ for Windows, the source of amqsdlq is supplied in the directory:

 c:\\IBM\WebSphere MQ\tools\c\samples\dlq

and the compiled version is supplied in the directory:

  c:\\IBM\WebSphere MQ\tools\c\samples\bin

In WebSphere MQ for UNIX systems, the source of amqsdlq is supplied in the directory:

/opt/mqm/samp/dlq (/usr/mqm/samp/dlq on AIX)

and the compiled version is supplied in the directory:

/opt/mqm/samp/bin (/usr/mqm/samp/bin on AIX)
