Overview of Oracle Database Scalability on Windows

Features in Oracle Database and in the Windows operating system work together to help increase scalability, throughput, and database capacity.

Large User Populations

Several features allow Oracle Database to support an increasingly large number of database connections on Windows.

  • The Shared Server Process, limits the number of threads needed in the Oracle Database process and supports over 10,000 simultaneous connections to a single database instance.

  • Oracle Net multiplexing and connection pooling features allow a large configuration to connect more users to a single database instance.

  • Oracle RAC raises connection counts dramatically by allowing multiple server computers to access the same database files, increasing the number of user connections by tens of thousands while increasing throughput.


    Oracle RAC is only supported on 64-bit Windows server operating systems.
