This metric signifies that the ASM has generated an incident due to a member evicted from the group by a member of the cluster database. This type of incident is typically related to Oracle Exception message ORA-29740.
The rest of the information in this section is only valid for this metric when it appears in either the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable).
The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

* Once an alert is triggered for this metric, it must be manually cleared.
For this metric you can set different warning and critical threshold values for each "Time/Line Number" object.
If warning or critical threshold values are currently set for any "Time/Line Number" object, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each "Time/Line Number" object, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.
The data comes from the alert log files. It is collected using the Perl script $ORACLE_HOME/sysman/admin/scripts/alertlogAdr.pl where $ORACLE_HOME refers to the home of the Oracle Management Agent.
Use Support Workbench in Enterprise Manager to examine the details of the incident. Note: This event does not automatically clear since there is no automatic way of determining when the problem has been resolved. Hence, you need to manually clear the event once the problem is fixed.
