4.1 Setup for handling possible errors in JP1/Base

JP1/Base provides the following features to minimize the effects of a failure in JP1/Base on system operations based on JP1/IM or JP1/AJS:

• Health check

  The function can detect hangups (infinite loops or deadlocks) or abnormal termination (other than forced termination) of processes such as process management, the event service, and event conversion.

• Detection of errors by the process management function

  The service can detect abnormal termination of a process managed by the process management service and switching of the authentication server.

• Restart when a process abnormally terminates

  JP1/Base restarts automatically if an error occurs in a process managed by the process management service.

• Restart the event service when a process abnormally terminates (UNIX only)

  JP1/Base restarts automatically if an error occurs in an event service process on the physical host.

• Hitachi Network Objectplaza Trace Library (HNTRLib2)

  JP1/Base uses the Hitachi Network Objectplaza Trace Library (HNTRLib2) to output log files that trace the system processing invoked in JP1/Base and in program products for which JP1/Base is a prerequisite program.

• Data collection when a failure occurs

  Troubleshooting information can be collected when a problem occurs in JP1/Base.

• Threshold-based suppression of event forwarding

  By setting a threshold to detect large numbers of events, you can automatically suppress forwarding of the events when large numbers of JP1 events occur.
