About Join Time-Outs
When you create a join condition using an All (AND) join or an Only one (XOR), you need to specify a join time-out. A join time-out specifies how long Integration Server waits for the other documents in the join condition. Integration Server uses the join time-out period to avoid deadlock situations (such as waiting for a document that never arrives) and to avoid duplicate service invocation.
How the join time-out affects document processing by the webMethods messaging trigger is different for each join type.
For an All (AND) join, the join time-out determines how long
Integration Server waits to receive an instance of each publishable document type in the condition.
For an Only one (XOR) join, the join time-out determines how long
Integration Server discards instances of publishable document types in the condition after it receives an instance document of one of the publishable document types.
An Any (OR) join condition does not need a join time-out.
Integration Server treats an Any (OR) join condition like a
webMethods messaging trigger with multiple simple conditions that all use the same trigger service.
