expdp到nfs有时候出现挂死的问题
之前在做xtts从aix到linux的操作中，表空间最后read only后的expdp到nfs后发现竟然卡死（read write情况下expdp是正常的）
检查状态发现是DEFINING
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 JOB_NAME OPERATION JOB_MODE STATE ATTACHED_SESSIONS
