An INTEGER specifying the number of semaphore sets available to the OpenEdge broker.
When more than 1,000 users connect to a single database, there might be high contention for the semaphore set. If there is a lot of semaphore contention on a system, using multiple semaphore sets helps alleviate this contention and improve performance on high user counts.
For more information on using semaphore sets, see OpenEdge Data Management: Database Administration.
