Oracle 11g Dataguard Duplicate物理备库配置

Oracle 11g Dataguard Duplicate物理备库配置(一)之物理备库创建配置
# ver:1.5 第五次修改

Oracle 11g DataGuard 物理备库配置及Active DataGuard测试

有关DG的相关概念,可参考:Oracle Data Guard Concepts and Administration
有关配置DG的参数描述,可参考:Oracle Data Guard 重要配置参数
基于同一主机配置 Oracle 11g Data Guard  
说明:
本文安装配置了Oracle 11g Dataguard通过duplicate方式创建物理备库。
比起上次配置有以下不同点:
1. 主备库目录结构不同。
2. 采用duplicate方式创建物理备库。

一、环境介绍
1. 主数据库环境
操作系统版本  : OEL5.8 x64
数据库版本    : Oracle 11.2.0.3 x64
数据库名      : orcl
数据库SID    : orcl
db_unique_name: orcl
instance_name : orcl
DGMGRL        : orcl_DGMGRL

2. 备库环境
操作系统版本  : OEL5.8 x64
数据库版本    : Oracle 11.2.0.3 x64 (只安装oracle数据库软件,no netca dbca)
数据库名      : slave
数据库SID    : slave
db_unique_name: slave
instance_name : slave
DGMGRL        : slave_DGMGRL

3. DataGuard启动顺序
启动顺序:先启备库,后启主库
关闭顺序:先关主库,后关备库
 
二、主数据库环境准备

1. 主库环境对比
充分利用主数据库原来环境,仅量不对主库参数配置做过多的修改。
重新创建口令文件
# su - oracle
$ orapwd file='/u01/app/oracle/product/11.2.0/db_1/dbs/orapworcl' password=oracle entries=10 force=y

2. 修改配置lisener监听文件
说明:添加dgmgrl静态监听配置,,为后面的dg broker配置打基础。
$ cat /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora 
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.200)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = orcl)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl_DGMGRL)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = orcl)
    )
  )
ADR_BASE_LISTENER = /u01/app/oracle
#其中的GLOBAL_DBNAME具有固定的格式:_DGMGRL.

4. 修改配置tnsname.ora文件
说明:ORCL是主库的服务名,DG是备库的服务名。
$ vi /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.200)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )
SLAVE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.150)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = slave)
    )
  )

5. 修改配置成规档模式
1)、检查数据库是否处于归档状态
SQL> archive log list;
SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database flashback on;
SQL> alter database open;

2)、将主库设置为 FORCE LOGGING 模式
SQL> alter database force logging;
SQL> select force_logging,flashback_on from v$database;
FOR FLASHBACK_ON
--- ------------------
YES YES

6. 修改主库参数文件
SQL>
alter system set instance_name='orcl' scope=spfile; 
alter system set db_unique_name='orcl' scope=spfile; 
alter system set local_listener='orcl' scope=spfile;
alter system set log_archive_config='DG_CONFIG=(orcl,slave)'; 
alter system set log_archive_dest_1='LOCATION=/u01/archivelog/ valid_for=(all_logfiles,all_roles) db_unique_name=orcl' scope=spfile;
alter system set log_archive_dest_2='SERVICE=slave lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=slave' scope=spfile; 
alter system set log_archive_format='arch_%r_%t_%s.arc' scope=spfile;
alter system set fal_client='orcl' scope=spfile;
alter system set fal_server='slave' scope=spfile; 
alter system set standby_file_management=AUTO; 
alter database add standby logfile group 4 '/u01/app/oracle/oradata/orcl/standby_redo04.log' size 50M; 
alter database add standby logfile group 5 '/u01/app/oracle/oradata/orcl/standby_redo05.log' size 50M; 
alter database add standby logfile group 6 '/u01/app/oracle/oradata/orcl/standby_redo06.log' size 50M; 
alter database add standby logfile group 7 '/u01/app/oracle/oradata/orcl/standby_redo07.log' size 50M; 
SQL> shutdown immediate;
SQL> startup;
 
三、备库配置
