The database client fault probe queries the dynamic performance view v$archive_dest to determine all possible destinations for archived redo logs. For every active destination, the probe determines whether the destination is healthy and has sufficient free space for storing archived redo logs.
If the destination is healthy, the probe determines the amount of free space in the destination's file system. If the amount of free space is less than 10% of the file system's capacity and is less than 20 Mbytes, the probe prints a message to syslog.
If the destination is in ERROR status, the probe prints a message to syslog and disables operations to determine whether the database is operational. The operations remain disabled until the error condition is cleared .
