备注：将dmp文件解析成sql语句
当需要查看数据泵导出的dmp文件内的sql语句，可以使用sqlfile,参考如下命令，该命令只转换成export.sql，不执行导入的操作。

FAQ
问题1: impdp或expdp 时报错,报错信息如下.
症状
ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
解决方式
1.先删除原先创建的备份目录
SQL> drop directory exp
2.重新创建新的备份目录
SQL> create or replace directory erp as '/u01/import ';
Directory created.
SQL> grant read,write on directory kmdata_exp to public ;
3.给文件夹授权
chown -R oracle:oinstall /u01/import
4.重新测试
问题2: 数据库存在版本差异
症状
当从高版本导入到低版本时是没有影响的. 但是当低版本导入高版本时会出现错误信息
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-39142: incompatible version number 5.1 in dump file "/u01/import/expdp_20201117.dmp"
解决方式
- 指定版本
expdp导出时,需要指定目标数据库的版本.如下方式
expdp erp/123456 directory=erp dumpfile=expdp_20201117.dmp logfile=expdp_log_20201117.log schemas=erp version=12.2.0.1.0
- 重新导入即可
