ISIS Dump With Log File Message "Forcing RNS Recalc on Process" (Doc ID 602614.1)

Last updated on FEBRUARY 13, 2017

Applies to:

Oracle Utilities Network Management System - Version 1.7.1.1 and later
Oracle Network Management for Utilities - DMS - Version 1.7.1.1 and later
Information in this document applies to any platform.

Symptoms

Network communication failures and an ISIS dump caused the system to become unresponsive.
The following message appears in the Service log files: "Forcing RNS Recalc on Process"

Expect services to recover from an ISIS dump.  The system might not recover from a network failure.  This is because the NMS ISIS bus is a real-time bus and it expects/requires messages to be dispersed and processed in a timely manner. If one of the services or sites do not respond in a certain amount of time, it will be declared dead and a restart of the associated process(es) would be necessary.

Due to this issue, users cannot access the system until a restart is performed.
