物理dataguard傻瓜实战
一、环境
1、环境准备
虚拟机连接方式：注意连接方式虚拟机net，同时点击edit，查看虚拟机网段
操作系统：Red Hat Enterprise Linux Server release 5.1 (Tikanga)
主库地址：192.168.220.3--虚拟机，安装
数据库
备库地址：192.168.220.4--虚拟机，未安装
数据库，只安装软件
检查数据库版本必须一致：
select * from v$version;
BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for
Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
检查db_name、sid必须一致
select instance_name from v$instance;
INSTANCE_NAME
----------------
orcl
SQL> show parameter db_name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_name string ice
二、主库配置
1、open数据库，
SQL> alter database force logging;
2、确认归档：
SQL> archive log list;
数据库日志模式 存档模式
自动存档 启用
最早的联机日志序列 6
下一个存档日志序列 10
当前日志序列 10
3、修改主库tnsnames（增加备库服务命名
只修改ip，数据库名和主库一致）
# tnsnames.ora Network Configuration File: /home/app/oracle10/product/10.2.0.1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
orcl =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.220.3)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
orcl2204 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.220.4)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
4、监听配置：
# listener.ora Network Configuration File: /home/app/oracle10/product/10.2.0.1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /home/app/oracle10/product/10.2.0.1)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = /home/app/oracle10/product/10.2.0.1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.220.3)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
5、虚拟机上测试是否能连主库，
注意连接方式虚拟机net，同时点击edit，查看虚拟机网段
本次虚拟机ip：192.168.220.3
[oracle@localhost ~]$ sqlplus /nolog
SQL*Plus: Release 10.2.0.1.0 - Production on Fri May 3 08:24:19 2013
Copyright (c) 1982, 2005, Oracle. All rights reserved.
SQL> conn system/orcl@orcl1
Connected.
6、创建pfile--主库
SQL> conn sys/orcl@orcl1 as sysdba
已连接。
SQL> create pfile ='/home/app/oracle10/initorcl.ora' from spfile;
文件已创建。
7、修改参数文件：
[oracle@localhost dbs]$ cat initorcl.ora
orcl.__db_cache_size=92274688
orcl.__java_pool_size=4194304
orcl.__large_pool_size=4194304
orcl.__shared_pool_size=62914560
orcl.__streams_pool_size=0
*.audit_file_dest='/home/app/oracle10/admin/ice/adump'
*.background_du
