ORA-24756: transaction does not exist問題解決

早上看alert日誌發現報錯如下：

檢視具體trace檔案/u01/app/oracle/diag/rdbms/bus/bus/trace/bus_reco_2590.trc內容如下:

ORA-01422: 實際返回的行數超出請求的行數,這種問題可能與應用有關係，由於早上事情比較多，沒有去查詢具體原因，只參考如下資料解決了下,因為我們部分操作是用的分散式交易[透過dblink]：
--------------------------------------------&gt>
Symptoms:

alert log:
ORA-24756: transaction does not exist

select local_tran_id,state from dba_2pc_pending;

36.26.310445 collecting

Cause:

If the remote database no longer exists then the transaction will have to be 
purged from the list of pending distributed transactions.

Solution:

1,
SQL> commit force '36.26.310445'; -- session is hanged

2,
SQL> exec DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY('36.26.310445'); 
BEGIN DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY('36.26.310445'); END;

*
ERROR at line 1:
ORA-30019: Illegal rollback Segment operation in Automatic Undo mode
ORA-06512: at "SYS.DBMS_TRANSACTION", line 65
ORA-06512: at "SYS.DBMS_TRANSACTION", line 85
ORA-06512: at line 1
---&gt>說明：然後運用SecureCRT以sysdba身份執行上述命令，成功，然後透過oracle級別和linux級別kill了步驟一中hang住的會話，過了一會兒透過EM檢視database頂級活動，那session已經不在了，alert日誌中也不報類似ORA-24756: transaction does not exist的錯誤了。

3,
SQL> commit;
SQL> alter session set "_smu_debug_mode" = 4;
SQL> commit;
SQL> execute DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY('local_tran_id');
SQL> commit;
