檢查一個資料庫的alert日誌時，檢視一些job報錯，由於是自己的測試庫，考慮把job停止掉。但是遇到如下錯誤：

sys@im1>exec DBMS_JOB.broken(275,true);

BEGIN DBMS_JOB.broken(275,true); END;

*

ERROR at line 1:

ORA-23421: job number 275 is not a job in the job queue

ORA-06512: at "SYS.DBMS_SYS_ERROR", line 86

ORA-06512: at "SYS.DBMS_IJOB", line 529

ORA-06512: at "SYS.DBMS_JOB", line 245

ORA-06512: at line 1

檢視了資料說：不是job的owner的使用者delete,remove，broken 一個job時，會報錯:ORA-23421: job number XXXX is not a job in the job queue

只有job的owner才能夠對job進行修改變更。

但是查詢找到job的owner priv_user

sys@im1>select job, what, log_user, priv_user,broken from dba_jobs where job=275;

JOB WHAT LOG_USER PRIV_USER B

---------- ---------------------------------------- ---------- ---------- -

275 WEB_SMS.cleanAppBuffer; SYSTEM SYSTEM N

2.以上面的sql語句priv_user登入資料庫

system@im1>exec DBMS_JOB.broken(295,false);

PL/SQL procedure successfully completed.

3.執行如下語句：

system@im1>exec DBMS_JOB.broken(295,true);

PL/SQL procedure successfully completed.

system@im1>commit;

Commit complete.

system@im1>select job, log_user, priv_user,broken from dba_jobs where job in (295);

JOB LOG_USER PRIV_USER B

---------- ---------- ---------- -

295 SYSTEM SYSTEM Y

另一種方法是以sys使用者：

sys@im1>exec DBMS_IJOB.broken(275,true);

PL/SQL procedure successfully completed.

sys@im1>select job, what, log_user, priv_user,broken from dba_jobs where job=275;

JOB WHAT LOG_USER PRIV_USER B

---------- ---------------------------------------- ---------- ---------- -

275 WEB_SMS.cleanAppBuffer; SYSTEM SYSTEM Y

sys@im1>exec DBMS_IJOB.broken(275,false);

PL/SQL procedure successfully completed.

sys@im1>select job, what, log_user, priv_user,broken from dba_jobs where job=275;

JOB WHAT LOG_USER PRIV_USER B

---------- ---------------------------------------- ---------- ---------- -

275 WEB_SMS.cleanAppBuffer; SYSTEM SYSTEM N

嘗試以system使用者執行命令此命令，會報錯：

system@im1>exec DBMS_IJOB.broken(295,false);

BEGIN DBMS_IJOB.broken(295,false); END;

ERROR at line 1:

ORA-06550: line 1, column 7:

最後一篇文章介紹當job$的索引INDEX I_JOB_JOB 損壞，也會導致此錯誤，對索引進行重建即可！
