    二：环境信息

操作系统版本：

uname -a
AIX egisbdb1 1 6 00F8A6874C00

数据库版本11.2.0.3.5

 

   三：问题原因

Error is caused by a stopped job that remained in the DBA_DATAPUMP_JOBS. The new expdp/impdp job has the same name as the old expdp/impdp job.

一个新的expdp/impdp job用的名字被一个已经停止了的datapump job所占用（When starting the new Data Pump job and using a system generated name, we check the names of existing Data Pump jobs in the dba_datapump_job in order to obtain a unique new system generated jobname.）

 

SQL> select owner_name, job_name, operation, job_mode,
  2         state, attached_sessions
  3  from   dba_datapump_jobs
  4  where  job_name not like 'BIN$%'
  5  order  by 1, 2;

OWNER_NAME JOB_NAME   OPERATION  JOB_MODE   STATE                          ATTACHED_SESSIONS
---------- ---------- ---------- ---------- ------------------------------ -----------------
SCOTT      JOB2       EXPORT     TABLE      NOT RUNNING                                    0

--果然如上所述，job2已经被一个not running 的job所占用

 

  四：解决方案

Clear the old job or specify a different name for the new job.

清除旧的job，或者给新的job选一个新的名字（不要和dba_datapump_jobs中名字有冲突）

1. Determine in SQL*Plus which Data Pump jobs exist in the database:

确定datapump job存在于数据库中

-- locate Data Pump jobs:

SET lines 200
COL owner_name FORMAT a10;
COL job_name FORMAT a20
COL state FORMAT a12
COL operation LIKE state
COL job_mode LIKE state
COL owner.object for a50select owner_name, job_name, operation, job_mode,
       state, attached_sessions
from   dba_datapump_jobs
where  job_name not like 'BIN$%'
order  by 1, 2;

2. Ensure that the listed jobs in DBA_DATAPUMP_JOBS are not active DataPump export/import jobs. The status should be 'NOT RUNNING'.

确定job不是活跃的，status字段应该显示为‘NOT RUNNING'

3. Check with the job owner that the job with status 'NOT RUNNING' in DBA_DATAPUMP_JOBS is not an export/import DataPump job that has been temporary stopped, but is actually a job that failed.

确认上面查到的'NOT RUNNING'的job不是别人临时暂停的，而是失败的任务

4. Determine in SQL*Plus the related master tables:

查看该任务的master表

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;

5. For jobs that were stopped in the past and won't be restarted anymore, delete the master table. E.g.:

删除已经'NOT RUNNING'并且不再会重新开始的任务

drop table scott.job2;

 

SQL> select * from dba_datapump_jobs;

OWNER_NAME JOB_NAME   OPERATION  JOB_MODE   STATE                    DEGREE ATTACHED_SESSIONS DATAPUMP_SESSIONS
---------- ---------- ---------- ---------- -------------------- ---------- ----------------- -----------------
SCOTT      BIN$/b7u4b EXPORT     TABLE      NOT RUNNING                   0                 0                 0
           a1AhTgQ8Co
           YBD/EQ==$0

 

--可以看到job2已经被放入recyclebin中了

6.purge recyclebin; 或者purge dba_recyclebin;

 

SQL> select * from dba_datapump_jobs;

no rows selected

7.Re-run the query on dba_datapump_jobs and dba_objects (step 1 and 4). If there are still jobs listed in dba_datapump_jobs, and these jobs do not have a master table anymore, cleanup the job while connected as the job owner. E.g.:

 

CONNECT scott/tiger

SET serveroutput on
SET lines 100
DECLARE
   h1 NUMBER;
BEGIN
   h1 := DBMS_DATAPUMP.ATTACH('SYS_EXPORT_TABLE_01','SCOTT');
   DBMS_DATAPUMP.STOP_JOB (h1);
END;
/

Note that after the call to the STOP_JOB procedure, it may take some time for the job to be removed. Query the view user_datapump_jobs to check whether the job has been removed:

CONNECT scott/tiger

SELECT * FROM user_datapump_jobs;

 

8.Confirm that the job has been removed:

CONNECT / as sysdba SET lines 200  COL owner_name FORMAT a10;  COL job_name FORMAT a20  COL state FORMAT a12  COL operation LIKE state  COL job_mode LIKE state  COL owner.object for a50-- locate Data Pump jobs:  SELECT owner_name, job_name, rtrim(operation) "OPERATION",        rtrim(job_mode) "JOB_MODE", state, attached_sessions  FROM dba_datapump_jobs WHERE job_name NOT LIKE 'BIN$%' ORDER BY 1,2;OWNER_NAME JOB_NAME            OPERATION JOB_MODE  STATE       ATTACHED ---------- ------------------- --------- --------- ----------- -------- SCOTT      EXPDP_20051121      EXPORT    SCHEMA    EXECUTING          1 SYSTEM     SYS_EXPORT_FULL_01  EXPORT    FULL      NOT RUNNING        0 -- locate Data Pump master tables: SELECT o.status, o.object_id, o.object_type,        o.owner||'.'||object_name "OWNER.OBJECT"   FROM dba_objects o, dba_datapump_jobs j  WHERE o.owner=j.owner_name AND o.object_name=j.job_name    AND j.job_name NOT LIKE 'BIN$%' ORDER BY 4,2; STATUS   OBJECT_ID OBJECT_TYPE  OWNER.OBJECT ------- ---------- ------------ ------------------------- VALID        85283 TABLE        SCOTT.EXPDP_20051121 VALID        85162 TABLE        SYSTEM.SYS_EXPORT_FULL_01
