1、创建测试表空间user02。这里我就不写创建语句了。
2、创建测试表
SQL>create table test (id number(5),name varchar2(5)) tablespace user02;
SQL>insert into test values(1,'jason');
SQL>commit;
3、sqlplus / as sysdba
SQL>alter system switch logfile;
4、rman target/
RMAN> backup database format '/oracle/databak/20110111/%U' plus archivelog format '/oracle/databak/20110111/%U' delete input;
RMAN>backup current controlfile format='/oracle/databak/20110111/%d.ctl' REUSE;
5、sqlplus / as sysdba
SQL>select * from test;

6、rman target/
