如何清除 DBA_DATAPUMP_JOBS 视图中的异常数据泵作业? (文档 ID 1626201.1)

2.1 查找在数据库中有哪些数据泵作业

set lines 200 pages 200
COL owner_name FORMAT a10; 
COL job_name FORMAT a20 
COL state FORMAT a12
COL operation LIKE state 
COL job_mode LIKE state

SELECT owner_name, job_name, operation, job_mode, 
state, attached_sessions 
FROM dba_datapump_jobs 
WHERE job_name NOT LIKE 'BIN$%' 
ORDER BY 1,2; 

OWNER_NAME JOB_NAME             OPERATION    JOB_MODE     STATE        ATTACHED_SESSIONS
---------- -------------------- ------------ ------------ ------------ -----------------
SYS        CSBLOG_JOB           EXPORT       SCHEMA       NOT RUNNING                  0

确保在dba_datapump_jobs中列出的作业不是活动的数据泵作业，状态应该是'NOT RUNNING'. 且确认是非暂停的作业。

2.2 查找相关的master表

col "OWNER.OBJECT" for a30
SELECT o.status, o.object_id, o.object_type, 
       o.owner||'.'||object_name "OWNER.OBJECT" 
  FROM dba_objects o, dba_datapump_jobs j 
 WHERE o.owner=j.owner_name AND o.object_name=j.job_name 
   AND j.job_name NOT LIKE 'BIN$%' ORDER BY 4,2;  

STATUS   OBJECT_ID OBJECT_TYPE         OWNER.OBJECT
------- ---------- ------------------- ------------------------------
VALID       252249 TABLE               SYS.CSBLOG_JOB

2.3 对于过去被终止的和根本不会再启动的作业，删除它的master表

SQL> drop table SYS.CSBLOG_JOB purge;

Table dropped.

2.4 重新检查

SELECT owner_name, job_name, operation, job_mode, 
state, attached_sessions 
FROM dba_datapump_jobs 
WHERE job_name NOT LIKE 'BIN$%' 
ORDER BY 1,2;

no rows selected

SELECT o.status, o.object_id, o.object_type, 
       o.owner||'.'||object_name "OWNER.OBJECT" 
  FROM dba_objects o, dba_datapump_jobs j 
 WHERE o.owner=j.owner_name AND o.object_name=j.job_name 
   AND j.job_name NOT LIKE 'BIN$%' ORDER BY 4,2;  

no rows selected
