Wildcard schemes

There are two wildcard schemes used to subscribe to multiple topics. The choice of scheme is a subscription option.

MQSO_WILDCARD_TOPIC

Select topics to subscribe to using the topic-based wildcard scheme.

This is the default if no wildcard schema is explicitly selected.

MQSO_WILDCARD_CHAR

Select topics to subscribe to using the character-based wildcard scheme.

Set either scheme by specifying the wschema parameter on the DEFINE SUB command. For more information, see DEFINE SUB.

Examples

IBM/+/Results
#/Results
IBM/Software/Results
IBM/*ware/Results

• Topic-based wildcard scheme
  Topic-based wildcards allow subscribers to subscribe to more than one topic at a time.
• Character-based wildcard scheme
  The character-based wildcard scheme allows you to select topics based on traditional character matching.
