Release 10.1A: OpenEdge Data Management:
Database Administration

> ## Semaphore Sets (-semsets)

> Operating system and syntax | UNIX | `-semsets` `n`
> Use with | Maximum value | Minimum value | Single-user default | Multi-user default
> DBS | Maximum Number of Users + 1 | 1 | – | 3

> ``n``

> An integer specifying the number of semaphore sets available to the broker.

> Use Semaphore Sets (-`semsets`) to change the number of semaphore sets available to the 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 improve performance on high user counts.
