全自动 TSPITR--基于RMAN-LOGSEQ

jasoname

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;
     ID NAME

 SQL> archive log list;

 Next log sequence to archive   60
 Current log sequence           60

 SQL>drop table test;
 SQL>alter system switch logfile;
6、rman target/
 
RMAN> recover tablespace user02 until logseq 60 auxiliary destination '/oracle/auxi/';

7、将表空间置于online
RMAN> sql 'alter tablespace user02 online';
测试：
SQL>selerct * from test;
