请检查残留进程和清理残留表
【1】
select owner_name,job_name,operation,job_mode,state,attached_sessions
from dba_datapump_jobs;

【2】
SELECT ‘drop table ‘|| o.owner||’.’||object_name ||’ purge ;’
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$%’;
