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。

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/

The authenticity of host '192.168.1.100 (192.168.1.100)' can't beestablished.

RSA key fingerprint is 25:ca:65:90:d3:30:fa:68:ed:11:64:b2:0e:b0:39:a7.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added '192.168.1.100' (RSA) to the list of knownhosts.

orapwJASON 100% 1536 1.5KB/s 00:00

[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'

*.compatible='11.2.0.4.0'

*.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

RMAN>

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
