DG_11g部署

前提

主库服务器上已安装数据库软件并创建实例
备库服务器上已安装数据库软件
主、备服务器/etc/hosts文中必须包含主备节点信息如下：

[root@db01:]$ more /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

## OracleBegin
192.168.40.55	db01
192.168.40.56	db02

环境准备

DATABASE_ROLE	DB_NAME	IPADDR	OS Version	DB version
Primary	fuwa	192.168.40.55	Red Hat7.6	11.2.0.4.0
Standby	wafu	192.168.40.56	Red Hat7.6	11.2.0.4.0

主库配置

主库开启归档，开启强制日志，关闭闪回，删除外部表

--开启归档,若已开启归档跳过该步骤
archive log list;
shutdown immediate
startup mount;
alter database archivelog;
alter system set log_archive_dest_1='location=/oradb/arch' scope=spfile; 
alter database open;
--强制日志写 no-->yes
select force_logging from v$database; 
alter database force logging;
--关闭闪回  no
select flashback_on from v$database;
--删除外部表
##xxx_external_locations 可以知道当前所有的目录对象以及相关的外部表，还会查询出这些外部表所对应的操作系统文件的名字。
##select * from all_external_locations;
##select * from user_external_locations;
##select * from dba_external_locations;

主库创建standby logfile

配置原则：
①standby logfile大小要和redo logfile大小相同；
②standby logfile要比redo logfile多一组，目前redo logfile是3组，因此创建4组standby logfile；
③为了安全，standby logfile可以包含多个member。

--查询日志组
set linesize 999
select group#,member from v$logfile order by 1;
    GROUP# MEMBER
---------- ----------------------------------------------------------------------
	 3 /data/oradata/fuwa/redo03.log
	 2 /data/oradata/fuwa/redo02.log
	 1 /data/oradata/fuwa/redo01.log

--查询日志大小
select group#,bytes/1024/1024 size_M from v$log;
    GROUP#     SIZE_M
---------- ----------
	 1	          50
	 2	          50
	 3	          50

#创建standby logfile
alter database add standby logfile group 4('/data/oradata/fuwa/redo04.log') size 50M;
alter database add standby logfile group 5('/data/oradata/fuwa/redo05.log') size 50M;
alter database add standby logfile group 6('/data/oradata/fuwa/redo06.log') size 50M;
alter database add standby logfile group 7('/data/oradata/fuwa/redo07.log') size 50M;

主库配置listener

--查看监听参数是否是默认监听，如果是空值则是默认监听，跳过该步骤
show parameter local_listener
---修改local_listener为默认监听
alter system set local_listener='';
show parameter local_listener

主库修改参数

生成pfile

startup
create pfile from spfile;
shutdown immediate

修改参数

参数模板可以在官方文档中查到，把其中的名称用自己的数据库名称替换即可。

#参数文件中追加如下内容
su - oracle
cd $ORACLE_HOME/dbs

通过pfile重新生成spfile并启动数据库

create spfile from pfile;
startup
shutdown immediate

拷贝相关文件至备库

拷贝参数文件、密码文件、监听文件志备库

	参数文件	密码文件	备注
源端	initfuwa.ora	orapwfuwa	名字不同
目标	initwafu.ora	orapwwafu

cd /data/u01/app/oracle/product/11.2.0/db/dbs

备库配置

备库创建静态监听并启动监听

--创建静态监听

   )

ADR_BASE_LISTENER = /data/u01/app/oracle

--重启监听
lsnrctl

备库参数修改

修改备库pfile

把主库名称修改为备库名称，备库名称修改为主库名称，但参数文件中的db_name要和主库名称一致。

备库按照参数文件创建目录

mkdir -p /data/u01/app/oracle/admin/wafu/adump
mkdir -p /data/oradata/wafu
mkdir -p /data/u01/app/oracle/fast_recovery_area/wafu
mkdir -p /data/oradata/archivelog

备库通过pfile生成spfile并启动数据库至nomount

su - oracle
sqlplus / as sysdba
create spfile from pfile;
startup nomount;

使用RMAN auxiliary恢复数据库

主库上操作
主库为open状态，备库为nomount 监听为启动状态
语法：rman target sys/密码@master auxiliary sys/密码@slave

#rman连接主备库
rman target 'sys/"top@123"'@fuwa auxiliary 'sys/"top@123"'@wafu
#说明：1个双引号扩密码，1个单引号扩 用户名+密码，即： '用户名/"密码"'@服务名
#复制
duplicate target database for standby from active database dorecover nofilenamecheck;
duplicate target database for standby from active database nofilenamecheck;

附录：详细步骤

#rman连接主备库
[oracle@db01:/data]$ rman target 'sys/"top@123"'@fuwa auxiliary 'sys/"top@123"'@wafu

2.原因
备库参数文件db_name和主库参数文件db_name参数不一致

3.解决办法
备库
1)更改备库参数文件db_name和主库参数文件db_name参数一致
2)重新生成spfile参数文件
shutdown immediate
create spfile from pfile;
startup nomount;
