某医院的HIS系统做OGG，过程中impdp遇到很多问题，oracle的BUG太坑爹了！！！ 环境： 生产库，AIX 10.2.0.4 RAC 容灾库：linux，10.2.0.5 单机，本地磁盘 存储是H3C的IP sun存储，平时存储磁盘IO很高，80%左右，数据量不是很大，150G左右，所以在晚上业务少
某医院的HIS系统做OGG，过程中impdp遇到很多问题，oracle的BUG太坑爹了！！！
环境：
生产库，AIX 10.2.0.4 RAC
容灾库：linux，10.2.0.5 单机，本地磁盘
存储是H3C的IP sun存储，平时存储磁盘IO很高，80%左右，数据量不是很大，150G左右，所以在晚上业务少的时候做了一次expdp，然后把dmp文件拷贝到linux机器上做impdp
容灾库由于本地磁盘，导入24小时的时候才报错，灰常坑爹！！！！
expdp：
expdp system/system directory=datapump DUMPFILE=his20140227a.dmp full=y logfile=expdp1.log
无报错，无警告，成功导出
impdp:
impdp system/system directory=datapump DUMPFILE=his20140227a.dmp full=y table_exists_action=replace logfile=impdp1.log job_name=imp1 PARALLEL=4
第一次报错：
ORA-39014: One or more workers have prematurely exited.
ORA-39029: worker 1 with process name "DW01" prematurely terminated
ORA-31672: Worker process DW01 died unexpectedly.
Job "SYSTEM"."LWGIMP04" stopped due to fatal error at 20:41:42

查了metalink，没有找到完全一样的错误描述，根据一些网友的建议，加了imp参数（metalink上也提到这个，文档:[ID 878626.1]，，，错误描述：ORA-39126: 在 KUPW$WORKER.PUT_DDLS [TABLE_STATISTICS] 中 Worker 发生意外致命错误），由于没有更好的办法，只能参考这个试试了
impdp system/system directory=datapump DUMPFILE=his20140227a.dmp full=y EXCLUDE=STATISTICS table_exists_action=replace logfile=impdp1.log job_name=imp1 PARALLEL=4
今天早上查看日志，完全一样的错误，又改了下impdp参数：
impdp system/system directory=datapump DUMPFILE=his20140227a.dmp full=y EXCLUDE=TABLE_STATISTICS table_exists_action=replace logfile=impdp1.log job_name=imp1 PARALLEL=4
同时根据网友某的建议，改了shared pool参数
impdp进行中，明天早上看结果吧，不知道这2个操作哪个能起作用
