数据库版本:9204
目标数据库名称 paul
辅助实例 AUX1


1.备份数据库用带恢复目录的模式
C:\Documents and Settings\Paul Yi>rman target / catalog paultest/paultest@dev89

Recovery Manager: Release 9.2.0.4.0 - Production

Copyright (c) 1995, 2002, Oracle Corporation.  All rights reserved.

connected to target database: PAUL (DBID=1605165889)
connected to recovery catalog database

2在paul数据库表空间ts_test下创建测试用户
C:\Documents and Settings\Paul Yi>sqlplus "/as sysdba"

SQL*Plus: Release 9.2.0.4.0 - Production on Wed Jan 2 14:15:45 2008

sql> create tablespace ts_test datafile 'd:\oracle\oradata\paul\ts_test01.dbf' size 50M;

SQL> create user test identified by test default tablespace ts_test;

User created.

SQL> grant connect,resource to test;

Grant succeeded.

SQL> conn test/test
Connected.
SQL> create table stu(no number,name varchar2(10));

Table created.

SQL> insert into stu values(109,'abcd');

1 row created.

SQL> select * from stu;

        NO NAME
---------- --------------------
       109 abcd

SQL> commit;

Commit complete.

SQL> conn /as sysdba
Connected.
备份控制文件
SQL> alter database backup controlfile to 'd:\control02.ctl' reuse;

Database altered.

SQL>

SQL> conn test/test
Connected.
SQL> select * from tab;

SQL> alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss';

SQL> drop table stu;

Table dropped.

3.为辅助实例创建初始化参数文件
新建 d:\oracle\oradata\aux1 目录
复制d:\oracle\ora92\database\INITpaul.ora 为initaux1.ora文件
然后修改其内容,将实例名字修改为:aux1, 添加lock_name_space=AUX1,修改control_files路径为:
control_files='d:\control02.ctl'
修改log_archive_start=false
辅助实例必须为非归档模式。
添加如下两个参数:
db_file_name_convert=("d:\oracle\oradata\paul", "d:\oracle\oradata\aux1")
log_file_name_convert=("d:\oracle\oradata\paul", "d:\oracle\oradata\aux1")

4. 创建辅助实例服务 用oradmin工具
C:\Documents and Settings\Paul Yi>oradim -new -sid aux1 -intpwd abcdefg -startmode manual
 
5.启动辅助实例到nomount状态
C:\Documents and Settings\Paul Yi>set oracle_sid=aux1

C:\Documents and Settings\Paul Yi>sqlplus "/as sysdba"
