使用具备dba权限的用户进行全库导出。
exp \'sys/tiger@orcl as sysdba\' file=/u01/oracle/full.dmp,/u01/oracle/fulll.dmp filesize=100m full=y
参数文件导出：
[oracle@localhost oracle]$ vi p1
[oracle@localhost oracle]$ exp parfile p1
[oracle@localhost oracle]$ vi p1
userid=scott/tiger
file=/u01/oracle/pfile.dmp
tables=emp
[oracle@localhost oracle]$ exp parfile=p1
query参数导出符合的数据：
userid=scott/tiger
file=/u01/dddd.dmp
tables=emp
query='where deptno in (10,20)'
imp
表不存在导入方式：imp scott/tiger file=/u01/oracle/scott.dmp tables=emp,dept
表存在的导入方式：imp scott/tiger file=/u01/scott.dmp tables=emp ignore=y
imp scott/tiger file=/u01/oracle/scott.dmp fromuser=v7hqs touser=v7hqs log=2014
将scott用户emp表导入s1用户：
imp system/tiger fromuser=scott touser=s1 file=/u01/oracle/scott.dmp tables=emp
