The DLQ handler rules table

The dead-letter queue handler rules table defines how the DLQ handler processes messages that arrive on the DLQ.

There are two types of entry in a rules table:

• The first entry in the table, which is optional, contains control data.
• All other entries in the table are rules for the DLQ handler to follow. Each rule consists of a pattern (a set of message characteristics) that a message is matched against, and an action to be taken when a message on the DLQ matches the specified pattern. There must be at least one rule in a rules table.

Each entry in the rules table comprises one or more keywords.
