impdp用NETWORK_LINK从远程库导入到本地库，导入表的速度还正常，导入索引的速度特别慢。2个小时才导1300个索引。

使用imp的格式：

impdp vebackup/abc DIRECTORY=DATABAK_DIR NETWORK_LINK=primarydb_link SCHEMAS=veasms TABLE_EXISTS_ACTION=REPLACE REMAP_SCHEMA=veasms:veasms logfile=impdpstan.log

原来库里面做了N个日志文件，每个大小50M。不知道这影不影响性能。

SQL> select member from v$logfile;
