清理NOT RUNNING的master表：
select 'drop table '||OWNER_NAME||'.'||JOB_NAME||' purge;' from dba_datapump_jobs where STATE='NOT RUNNING';
--执行结果用来执行，再次查看结果为空：
SQL> select * from dba_datapump_jobs;
no rows selected
按MOS建议，将导出任务移动到本地文件系统：
AIX源端导出XTTS源数据至源端/hxbak/xtts_exp目录中，而后copy至nfs共享存储/xtts/dmp中:
mkdir /hxbak/xtts_exp
chown oracle:dba /hxbak/xtts_exp
ls -ld /hxbak/xtts_exp
select * from dba_directories;
create or replace directory XTTS as '/hxbak/xtts_exp';
此时测试expdp任务可正常运行：
$ expdp \'/ as sysdba\' directory=XTTS tables=query.test dumpfile=query_test.dmp logfile=query_test.log

再次导出其他元数据：
#expdp_xtts.sh (about 5min)
nohup sh expdp_xtts.sh &
#expdp_xtts_other.sh(about 5min)
nohup sh expdp_xtts_other.sh &
#expdp_tmp_table
nohup sh expdp_tmp_table01.sh &
nohup sh expdp_tmp_table02.sh &
nohup sh expdp_tmp_table03.sh &
nohup sh expdp_tmp_table04.sh &
最后将这些导出文件再移动到/xtts/dmp/下，供后续xtts测试目标端导入使用：
$ pwd
/hxbak/xtts_exp
$ cp -rp * /xtts/dmp/
目标端导入时只需要有读这些文件的权限，即可，实际测试恢复OK。
