Resolution
CRS - Alert Log Message
This alarm is invoked for received CRS alert log messages, based on a predefined list of messages in the Global Administration. The CRS alert log file keeps track of general information regarding the CRS processes core activity. Errors associated with these aspects can indicate availability, usability or performance issues that require immediate attention.CRS - Alert Log Summary
This alarm is invoked when the number of errors detected in the alert log exceeds a predefined threshold. The CRS alert log file keeps track of general information regarding the CRS processes core activity. Errors associated with these aspects can indicate availability, usability or performance issues that require immediate attention.CRS - Collection Status
This alarm is invoked when Foglight data collection has failed.
CRS - Resource Offline
This alarm is invoked when a Cluster Ready Services registered resource goes offline. Depending on the exact resource in offline state, the Oracle, application or both could be having an immediate availability issue
CRS - Usability Connection Availability
This alarm is invoked when the connection to the operating system has failed. Such a failure can result from a server that is not running (down), overloaded or inaccessible from the network. When the database machine (host) is unavailable, the database is unavailable as well - either down or inaccessible, thereby possibly leading to application failure.DBO - CRS Agent Not Configured
This alarm is invoked when the monitored environment is a Real Application Cluster and the CRS agent is not configured. CRS is the infrastructure layer which manages cluster coordination in a RAC environment. When the CRS agent is not configured, alarms on CRS errors and offline resource will not be invoked.
