RMAN下的传输表空间
上一篇 / 下一篇 2010-07-19 09:14:34 / 个人分类：ORACLE-based
当业务系统运行中，几天后发现前面删除了一个表，这个时候不能FLASHBACK DROP了。我们的传输表空间就能派上用场了
注意条件是在归档模式下
SQL> create tablespace rman datafile '/u01/app/oracle/oradata/shujukuai/rman.dbf‘ size 100m autoextend on next 10m maxsize 200m;
Tablespace created.
SQL> create table t tablespace rman as select * from dba_objects where rownum<1;
Table created.
SQL> insert into t select * from dba_objects;
50041 rows created.
SQL> commit;
Commit complete.
SQL> select sysdate from dual;
SYSDATE

SQL> drop table t purge;
Table dropped.
验证表空间RMAN是否自包含
SQL> execute dbms_tts.transport_set_check('rman',true);
PL/SQL procedure successfully completed.
SQL> select * from transport_set_violations;
no rows selected

创建TARGET的密码文件及修改网络联系相关的配置使可以远程连接到TARGET实例
|
|
创建辅助实例的目录，分别在$ORACLE_BASE/oradata和$ORACLE_BASE/admin下建立相应的目录
|
|
创建辅助实例的PFILE，注意添加：log_file_name_convert和db_file_name_convert
|
|
辅助实例的PFILE中，db_unique_name必须不同与TARGET实例，但必须与ORACLE_SID、以及上述相关的目录名称相同，因为需要在本地登录辅助数据库
|
|
辅助实例的PFILE中，db_name必须与TARGET的db_name相同
