Overview of Oracle Database on Windows Architecture

Oracle Database on Windows is a stable, reliable, and a high-performing system upon which you can build applications. Each release of the database provides new platform-specific features for high performance on Windows.

Oracle Database operates the same way on Windows as it does on the other platforms.

• Oracle Automatic Storage Management
  Oracle Automatic Storage Management (Oracle ASM) is an integrated file system and volume manager expressly built for Oracle Database files.
• Oracle Automatic Storage Management File Access Control
  Oracle ASM File Access Control restricts the access of files to specific Oracle ASM clients that connect as SYSDBA.
• Thread-Based Architecture
  Threads allow concurrent operations within an operating system process so that a process can run different parts of its program simultaneously on different processors.
• File I/O Enhancements
  Oracle Database supports 64-bit file I/O to allow the use of files larger than 4 gigabytes (GB).
