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

相关阅读:配置Oracle 11g的Dataguard测试,创建物理备库(Physical Standby Database)
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:
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
