晚上做了一下创建恢复目录的实验，整理了一下，供自己以后参考
环境：
源库：oracle10gr2 源OS：rhelas4 源sid=ora10 源库ip=192.168.1.200
目标库： oracle10gr2 目地OS：rhelas4 目的sid=ora10hha 目的库ip=192.168.1.10
实验目的：
要将源库192.168.1.200 上的数据文件、控制文件以及日志文件备份到 目的库192.168.1.10上，以便源库出现问题时，可以通过
备份目录恢复。
实验准备：
1：在虚拟机上安装好两个redhat系统，源库ip=192.168.1.200，目的库ip=192.168.1.10
并分别创建好两个库，一个ora10库 ， 一个orahha库
同时关闭两个redhat系统上的防火墙，确保这两个OS都可以相互ping通
2：在目的库（192.168.1.10）上通过图形化界面执行netca命令，配置好监听，配置好的listener.ora 如下
ora10hha =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
3：在源库（192.168.1.200)上通过图形化界面执行netca命令，配置好tnsname.ora ，配置好的内容如下：
ORA10HHA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ora10hha)
)
)
4：在源库(192.168.1.200)上执行客户端到服务器端的连接是不是正常：
[oracle@sphost admin]$ tnsping ORA10HHA
TNS Ping Utility for Linux: Version 10.2.0.1.0 - Production on 03-MAY-2011 23:22:19
Copyright (c) 1997, 2005, Oracle. All rights reserved.
Used parameter files:
/home/oracle/10.2.0/network/admin/sqlnet.ora
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = ora10hha)))
OK (80 msec)
[oracle@sphost admin]$
ok，这样就可以通过网络连接到目的库上了。
5：在源库(192.168.1.200)上执行
[oracle@sphost admin]$ sqlplus sys/sysdba@ORA10HHA as sysdba

SQL>
6：在源库(192.168.1.200)上创建表空间，用于存放恢复目录数据，
并创建用户，该用户是恢复目录的拥有者；同时给用户授予查询、维护恢复目录的权限
SQL> create tablespace tbs_catalog datafile '/home/oracle/oradata/catalog.dbf' size 1G;
Tablespace created.
SQL> create user rman identified by rman temporary tablespace temp default tablespace tbs_catalog quota unlimited on tbs_catalog;
User created.
SQL> grant connect,resource,recovery_catalog_owner to rman;
Grant succeeded.
SQL>
7：启动rman
oracle@sphost admin]$rman
一定要注意：如果此处输入rman后，一直没有反应，那么就执行如下命令：
[oracle@sphost admin]$ export PATH=$ORACLE_HOME/binPATH:.
[oracle@sphost admin]$ rman

RMAN>
8：以用户rman身份连接到恢复目录所在的数据库中
RMAN> connect catalog rman@ORA10HHA
recovery catalog database Password:
connected to recovery catalog database
RMAN>
当然，在这里我的恢复目录是已经创建好了的，如果还没有创建的话，在执行这条命令后，显示如下：
recovery catalog database Password:
connected to recovery catalog database
recovery catalog is not installed
9：因此要创建恢复目录
在这里一定要注意，创建的恢复目录名一定要和刚创建的表空间名字一直，否则无效。如下：
RMAN> connect catalog rman@ORA10HHA
recovery catalog database Password:
connected to recovery catalog database
RMAN> create catalog tablespace tt;
ORACLE error from recovery catalog database: ORA-00959: tablespace 'TT' does not exist
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-06433: error installing recovery catalog
RMAN> create catalog tablespace tbs_catalog;
recovery catalog created
RMAN> exit
10：测试恢复目录是否创建成功。
[oracle@sphost ~]$ sqlplus sys/sysdba@ORA10HHA as sysdba

如果这些表不存在，则表示恢复目录没有创建成功。
11.将数据库注册到恢复目录
[oracle@catalog ~]$ rman

Copyright (c) 1982, 2005, Oracle. All rights reserved.
RMAN> connect target ora10; ////连接到源库
target database Password:
connected to target database: ORA10HHA (DBID=3339398398)
RMAN> connect catalog rman@ORA10HHA ////连接到恢复目录，感觉这边随意输入任何密码都是可以的
recovery catalog database Password:
connected to recovery catalog database
RMAN> register database; /// 把源数据库的信息注册到恢复目录中
database registered in recovery catalog
starting full resync of recovery catalog

RMAN> exit
