ORA: ORACLE12C导入11G IMP备份文件

前提：用户传一个ORACLE11G (版本11.2.0.1.0) 的IMP备份文件，需要分析效率。

将其还原到 WIN2012+ ORACLE 12C环境。

还原过程如下：

D:\app\product\12.1.0\dbhome_1\BIN>impDP 'sys/dba密码 as sysdba' directory=DA
TA_DUMP_DIR schemas=system dumpfile=EVCTMSdb.dmp

Import: Release 12.1.0.1.0 - Production on Sat Aug 20 06:35:39 2022

Connected to: Oracle Database 12c Release 12.1.0.1.0 - 64bit Production
ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-39087: directory name DATA_DUMP_DIR is invalid

原因：
原值： “D:\app/admin/orcl/dpdump/” 表述不正确
解决方式：
重建立有效的备份路径
create OR REPLACE directory DATA_PUMP_DIR as 'D:\app\admin\orcl\dpdump';

D:\app\product\12.1.0\dbhome_1\BIN>

D:\app\product\12.1.0\dbhome_1\BIN>impDP 'sys/dba密码 as sysdba' directory=BA
CKUP_DIR TABLESPACES=CTMS dumpfile=EVCTMSdb.dmp
