PIE®/CICS-NonStop

CICS availability is critical. Recognizing the need for recovery systems, you could use an automated operator to restart a region after it fails, however, the time needed to restart a region can take a minute or more. If the system produces a dump, you are delayed until the dump completes and, in addition, have to wait for all CICS recovery procedures to finish. Your system is unavailable for most of the recovery period.

To combat this, PIE/CICS-NonStop runs multiple, fully initialized regions. Backup regions are available immediately when problems occur. PIE/CICS-NonStop re-assigns users while recovery procedures continue in the failed region.

PIE/CICS-NonStop does not have to wait for the entire period to complete a dump. Usually, a dump takes two minutes or less. In most cases, users are re-assigned to the backup region immediately after a failure. PIE/CICS-NonStop handles both local and remote terminals. Unlike XRF, PIE/CICS-NonStop does not need to continuously monitor CICS regions, therefore, the performance overhead of running PIE/CICS-NonStop is less.

Users are automatically routed to an appropriate region by PIE/CICS-NonStop. Users need only one logon procedure, regardless of how many regions they use. No special knowledge or training is required to access different regions. PIE/CICS-NonStop provides load balancing by automatically distributing user load across regions exactly to your specifications.
