Differences Between SMP Systems and HP
NonStop Servers
The WebLogic Server instances are distributed across all the available CPUs (which
are loosely coupled). A JVM and all its threads run within the CPU where the JVM was
started, so, when a CPU is lost, only WebLogic Server instances running on that CPU
are affected. WebLogic Server instances on other CPUs are not affected. The
WebLogic Server instances on the failed CPU can be automatically restarted on other
CPUs without reconfiguration and migration requirements.
Fault-tolerance is provided by every component (such as TCP/IP, TMF, and SQL/MX)
so the WebLogic Server application on a NonStop server is always available.
Moreover, the node manager and administrative server are monitored to restart
automatically if the processor they run on fails (or the process itself fails for other
reasons). This method provides continued availability of monitoring and management
services.
The deployment benefits of the NonStop server, such as tight integration with the fault-
tolerant transaction manager, massively scalable relational database, and TCP/IP are
transparently provided to the WebLogic Server application when deployed on a
NonStop server.
