由于是在Processing object type SCHEMA_EXPORT/TABLE/STATISTICS/TABLE_STATISTICS报的错，错误和统计信息有关，网上介绍说是一个bug，impdp时加上EXCLUDE=STATISTICS，导入后手动收集统计信息。
尝试如下，导入完成：
[oracle@rac1 ~]$ impdp \'/ as sysdba \' directory=expdp dumpfile=wxlun0402.dmp logfile=wxlun0402.impdplog REMAP_TABLESPACE=wxlun:wxlun_DATA REMAP_SCHEMA=wxlun:wxlun0402 EXCLUDE=STATISTICS
