昨天一测试环境出现异常ORA-55617: Flashback Archive "XXXXX" runs out of space and tracking on "XXXX"，其解释如下：
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没有设置配额，理论上应该是无限制才对，实际是用了5GB多之后出现该异常，表空间为自动扩展。所以解释有误，经测试，修改配合后问题解决，如下：
alter flashback archive HD_FDA modify tablespace hd_fbda quota 30g;
