NOFAILOVER action specified for certain Oracle errors

Last published : Sep 09, 2026
The High Availability agent for Oracle provides enhanced handling of Oracle errors encountered during detailed monitoring. The agent uses the reference file oraerror.dat, which consists of a list of Oracle errors and the actions to be taken.
See the Cluster Server Configuration and Upgrade Guide for a description of the actions.
Currently, the reference file specifies the NOFAILOVER action when the following Oracle errors are encountered:
ORA-00061, ORA-02726, ORA-6108, ORA-06114
The NOFAILOVER action means that the agent sets the resource's state to OFFLINE and freezes the service group. You may stop the agent, edit the oraerror.dat file, and change the NOFAILOVER action to another action that is appropriate for your environment. The changes go into effect when you restart the agent.
