昨天一測試環境出現異常ORA-55617: Flashback Archive "XXXXX" runs out of space and tracking on "XXXX"，其解釋如下：

Description: Flashback Archive "string" runs out of space and tracking on "string" is suspended
Cause: Flashback archive tablespace quota is running out.
Action: Add tablespace or increase tablespace quota for the flashback archive.

FBA沒有設定配額，理論上應該是無限制才對，實際是用了5GB多之後出現該異常，表空間為自動擴充套件。所以解釋有誤，經測試，修改配合後問題解決，如下：

alter flashback archive HD_FDA modify tablespace hd_fbda quota 30g;
