RMAN Duplicate database from Active database with ASM
一、 环境
主库：安装grid软件及创建磁盘组；安装数据库软件并创建数据库，
备库：仅安装grid软件并创建asm磁盘组，同时安装数据库软件即可。
主机名 | 数据库版本 | dbname | ORACLE_SID | ip地址 | 系统版本 |
server1(主) |
oracle11204 |
Jason
| jason | 192.168.1.250 |
rhel6.6_x86_64 |
server2(备) | jason | 192.168.1.252 |
二、 主库配置
1. 开启归档
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +DATA
Oldest online log sequence 24
Next log sequence to archive 26
Current log sequence 26
2. 配置监听及tnsname
grid用户创建监听，如下：
[grid@server1 ~]$ cd /u01/app/11.2.0/grid/network/admin/
[grid@server1 admin]$ cat listener.ora
# listener.ora Network Configuration File:/u01/app/11.2.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL =IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL =TCP)(HOST = server1)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u01/app/grid
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
oracle用户下tnsname.ora配置如下
[oracle@server1 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/
[oracle@server1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File:/u01/app/11.2.0/grid/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
JASONPRI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.1.250)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = JASON)
)
)
JASONSTD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.1.252)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = JASON)
)
)
[oracle@server1 admin]$ lsnrctl status

[oracle@server1 admin]$
3. 生成pfile文件，同步相应文件至备库
在主数据库生成pfile文件。
SQL> create pfile=’/home/oracle/pfile.ora’ from spfile;
File created.
同步密码认证文件至备机。
[oracle@jason1 dbs]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/dbs
[oracle@jason1 dbs]$ scp initJASON.ora orapwJASON 192.168.1.252:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/

[oracle@jason1 dbs]
三、 备库配置
4. 创建对应目录
备库上创建相关目录
[oracle@server2 oracle]$ mkdir -p /u01/app/oracle/admin/JASON/adump
5. 备库参数文件配置
备库上修改初始参数文件，参数如下。
JASON.__db_cache_size=67108864
JASON.__java_pool_size=4194304
JASON.__large_pool_size=8388608
JASON.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment
JASON.__pga_aggregate_target=209715200
JASON.__sga_target=201326592
JASON.__shared_io_pool_size=0
JASON.__shared_pool_size=113246208
JASON.__streams_pool_size=0
*.audit_file_dest='/u01/app/oracle/admin/JASON/adump'
*.audit_trail='db'

*.control_files='+DATA'
*.db_block_size=8192
*.db_create_file_dest='+DATA'
*.db_domain=''
*.db_name='JASON'
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=JASONXDB)'
*.log_archive_dest_1='LOCATION=+DATA'
*.log_archive_dest_state_1='ENABLE'
*.log_archive_format='%t_%s_%r.dbf'
*.memory_target=411041792
*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_tablespace='UNDOTBS1'
6.配置监听
grid用户创建监听，备库监听必须配置为静态监听。如下：
[grid@server2 admin]$ cat listener.ora
# listener.ora Network Configuration File:/u01/app/11.2.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = JASON2)
(ORACLE_HOME =/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = JASON)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL =IPC)(KEY = EXTPROC1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL =TCP)(HOST = server2)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u01/app/grid
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER = ON
oracle用户下tnsname.ora配置如下
[oracle@server1 ~]$ cd/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/
[oracle@server1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File:/u01/app/11.2.0/grid/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
JASONPRI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.1.250)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = JASON)
)
)
JASONSTD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.1.252)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = JASON)
)
)
7. 创建备库
将备库启动到nomount状态，然后在备机连接主库进行duplicate操作。
[oracle@server2 ~]$ rman target sys/system@JASONPRI auxiliarysys/system@JASONSTD

备注：创建备库后，数据库处于OPEN状态.
8. 创建spfile文件
备库创建结束后，需要创建spfile文件。
修改pfile文件control_files参数，指定备库的控制文件，查看asm磁盘组获取控制文件名及位置。如下：
control_files='+DATA/jason/controlfile/current.257.920517339'，
创建spfile.
SQL> create SPFILE='+DATA/JASON/spfileJASON.ora' frompfile='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initJASON.ora';
File created.
SQL>
创建pfile文件指向
[oracle@server2dbs]$ cat initJASON.ora
SPFILE='+DATA/JASON/spfileJASON.ora'
[oracle@server2dbs]$
spfile文件创建成功后，备库重启将使用spfile文件启动数据库
SQL> showparameter spfile
NAME TYPE VALUE
----------------------------------------------- ------------------------------
spfile string +DATA/jason/spfilejason.ora
SQL>
四、 注册CRS
注册CRS
备库未注册入CRS,同时备机重启仅ASM实例与crs启动,CRS无法启动数据库。因此注册备库至CRS中。
以oracle用户执行
[oracle@server2 dbs]$ srvctl add database -d JASON -o/u01/app/oracle/product/11.2.0/dbhome_1 -p +DATA/JASON/spfileJASON.ora -i jason -n jason
[oracle@server2 dbs]$ srvctl modify database -d JASON -a 'data'
[oracle@server2 dbs]$ srvctl config database -d jason -a
