ORA-02067: transaction or savepoint rollback required
這個錯誤是ORA-600[1265]錯誤引發的，隨后還出現了ORA-600[17281]、ORA-4088和ORA-2067錯誤。其中ORA-2067的描述為：
$ oerr ora 2067
02067, 00000, "transaction or savepoint rollback required"
// *Cause: A failure (typically a trigger or stored procedure with multiple
// remote updates) occurred such that the all-or-nothing execution
// of a previous Oracle call cannot be guaranteed.
// *Action: rollback to a previous savepoint or rollback the transaction
// and resubmit.
從這個描述和Oracle的報錯信息不難判斷，Oracle在通過觸發器更新遠端表時引發了這個600錯誤。
根據Oracle的MOS文檔Bug 5655419 Distributed transaction hits ORA-600:[1265] or ORA-600:[k2gget: downgrade] in 10.2的描述，這個錯誤和分布式事務有關，確認影響的版本就是當前環境的10.2.0.4。這個錯誤的產生一般與窗口維護有關，可以看到問題的發生時刻恰好是22點，從這個時刻開始，Oracle進入維護窗口，進行空間回收統計信息收集等后臺工作，顯然就是因為窗口的變化導致了這個錯誤的產生。
Oracle在11.1.0.6中FIXED了這個bug。除了版本升級外，可以考慮將包含分布式事務修改的程序放到遠離時間窗口改變時間。
