Overview of WebSphere Real Time for AIX on 64-bit POWER

WebSphere® Real Time for AIX® on 64-bit POWER® bundles real-time capabilities with the standard JVM.

Features of WebSphere Real Time for AIX on 64-bit POWER

Real-time applications need consistent run time rather than absolute speed.

The main concerns when deploying real-time applications with traditional JVMs are as follows:
  • Unpredictable (potentially long) delays from Garbage Collection (GC) activity.
  • Delays to method runtime as Just-In-Time (JIT) compilation and recompliation occurs, with variability in execution time.
  • Arbitrary operating system scheduling.
WebSphere Real Time for AIX on 64-bit POWER removes these obstacles by providing:
  • The Metronome Garbage Collector, an incremental, deterministic garbage collector with very small pause times
