初始化工作
首先建立目录：
$ sudo mkdir /u01/dumpdir
$ sudo chown oracle:oinstall /u01/dumpdirPDB数据库中创建directory:
SQL> alter session set container=orclpdb1;Session altered.SQL> create directory dp_dir as '/u01/dumpdir';Directory created.SQL> set pagesize 0
SQL> select owner, directory_name, directory_path from dba_directories;
SYS DP_DIR /u01/dumpdir
SYS XMLDIR /u01/oracle/product/12.2.0.1/dbhome_1/rdbms/xml

SYS ORACLE_BASE /u01/oracle
SYS ORACLE_HOME /u01/oracle/product/12.2.0.1/dbhome_113 rows selected.创建用户dpuser，并赋予权限：
SQL> show con_name;

SQL> create user dpuser identified by "foo";User created.SQL> grant create session, create table to dpuser;Grant succeeded.SQL> grant read, write on directory dp_dir to dpuser;Grant succeeded.
SQL> alter user dpuser quota 100m on users;User altered.使用dpuser创建一些表：

----------1使用参数文件的一个好处是转义会简单些，例如使用SYS用户的命令行为：
$ impdp 'sys/Abcdef_123456 as sysdba'而使用参数文件则写为：
$ cat expsys.par
userid="sys/Abcdef_123456 as sysdba"整库导出
参数文件为：
[oracle@oracle-12201-vagrant-dev ~]$ cat exp.par

logfile=exp.log
