db_recovery_file_dest_size 滿導致資料庫啟動失敗，db資料庫
啟動資料庫時：

利用10046 事件追蹤資料庫開啟過程：

Consider changing RMAN RETENTION POLICY. If you are using Data Guard,   then consider changing RMAN ARCHIVELOG DELETION POLICY.2. Back up files to tertiary device such as tape using RMAN   BACKUP RECOVERY AREA command.3. Add disk space and increase db_recovery_file_dest_size parameter to   reflect the new space.4. Delete unnecessary files using RMAN DELETE command.

原來是flash_recovery_area滿了，無法進行歸檔。增加db_recovery_file_dest_size：

至此已經開啟資料庫，所以資料庫啟動失敗，我們利用10046事件跟蹤就能發現具體的原因。
