When fast-start failover (FSFO) is enabled, this metric will generate a critical alert on the new primary database (old standby database) if an FSFO occurs. The FSFO SCN (system change number) must be initialized to a value before the metric will alert. This usually takes one collection interval. Once an FSFO occurs and the new primary is ready, the FSFO alert fires. It then clears after one collection interval. A critical alert is configured by default.
Both primary and standby must be configured with sysdba monitoring access.
Shows the time when a fast-start failover occurred.
The value is 0 if FSFO has not occurred, 1 if FSFO has occurred.
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.
