Configuring an SMP Environment

Configuring the SMP environment is similar to configuring a uniprocessor environment, although SMP machines are typically more powerful and handle many more users. In an SMP environment, you can also control the number of engines.

• Thread Pools
  Thread pools group CPU resources, and contain threads used to execute SAP ASE tasks associated with that thread pool.
• Managing Engines
  To achieve optimum performance from an SMP system, you must maintain the correct number of engines.
• Starting and Stopping Engines
  Use sp_engine to start and stop SAP ASE engines.
• Managing User Connections
  (Process mode only) During process mode, if the SMP system supports network affinity migration (the process of moving network I/O from one engine to another.
• Configuration Parameters That Affect SMP Systems
  Some configuration parameters, such as spinlock ratios, apply only to SMP systems.
