在同事搭建的数据库上面导入数据时，提示ORA-39087 Unable to open the log file和ORA-39070 directory name DPDATA1 is invalid错误。
[oracle@XLJ181 dump]$ impdp cams_core/123456 dumpfile=BP_VOUCHER_20181016.dmp directory=dpdata1 REMAP_TABLE=BP_VOUCHER:BP_VOUCHER_20181018 logfile=import.log Import: Release 11.2.0.4.0 - Production on Thu Oct 18 09:59:01 2018 Copyright (c) 1982, 2011, Oracle and/or its affiliates.

下面是问题分析的思路：
1.首先，检查directory是否已创建
结果是directory已经创建，这里没有问题。
2.然后，检查Linux服务器上是否已创建目录：
检查目录是否存在
显然，目录已经创建。
3.检查是否未赋予directory的读写权限，执行赋权限语句：
grant read,write on directory dpdata1 to public;
再次执行导入语句进行验证：
[oracle@XLJ181 dump]$ impdp cams_core/123456 dumpfile=BP_VOUCHER_20181016.dmp directory=dpdata1 REMAP_TABLE=BP_VOUCHER:BP_VOUCHER_20181018 logfile=import.log
问题顺利解决，数据成功导入。
