二、 主库配置
1. 确定主数据库开启强制LOGGING模式
[oracle@jason1 ~]$ sqlplus /nolog
SQL*Plus: Release 11.2.0.4.0 Production on Thu Jul 14 20:45:33 2016
Copyright (c) 1982, 2013, Oracle. All rights reserved.
SQL> conn /as sysdba
Connected.
SQL> ALTER DATABASE FORCE LOGGING;
Database altered.
SQL> select force_logging from v$database;
FOR
---
YES
2. 开启归档
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 3
Next log sequence to archive 5
Current log sequence 5
SQL> select group#,bytes/1024/1024 from v$log;
GROUP# BYTES/1024/1024
---------- ---------------
1 50
3 50
2 50
3. 创建standby日志组
1).standby redo log的文件大小与primary 数据库online redo log 文件大小相同
2).standby redo log日志文件组的个数依照下面的原则进行计算
Standby redo log组数公式>=(每个instance日志组个数+1)*instance个数
例如在我的环境中，只有一个节点，这个节点有三组redo，所以
Standby redo log组数公式>=(3+1)*1 == 4
所以需要创建4组Standby redo log
3).每一日志组为了安全起见，可以包含多个成员文件。
查看主数据库的日志组个数与大小，创建standy日志组,大小不能小于在线日志大小。
SQL> select member from v$logfile;
MEMBER
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/JASON/redo03.log
/u01/app/oracle/oradata/JASON/redo02.log
/u01/app/oracle/oradata/JASON/redo01.log
在主数据库创建standby日志组，位置与原日志组相同的路径。
SQL> ALTER DATABASE ADD STANDBY LOGFILE('/u01/app/oracle/oradata/JASON/standby01.log') SIZE 50M;
Database altered.
SQL> ALTER DATABASE ADD STANDBY LOGFILE('/u01/app/oracle/oradata/JASON/standby02.log') SIZE 50M;

7 STANDBY/u01/app/oracle/oradata/JASON/standby04.log
7 rows selected.
4. 主库参数文件配置
在主库上修改dataguard配置相关的各个参数，各参数的具体含义可以参考oracle在线文档。

5. 配置监听及tnsname
创建监听及tnsname.ora，备库监听必须使用静态监听，如下：
[oracle@jason1 admin]$ cat listener.ora
# listener.ora Network Configuration File:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = JASON1)
(ORACLE_HOME =/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = JASON)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.1.99)(PORT = 1521))
)
ADR_BASE_LISTENER = /u01/app/oracle
[oracle@jason1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
JASON1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.1.99)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = JASON1)
)
)
JASON2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.1.100)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = JASON2)
)
)
[oracle@jason1 admin]$lsnrctl status

6. 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 from spfile;
File created.
把dbs下的内容同步到standby主机上面，
[oracle@jason1 dbs]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/dbs
[oracle@jason1 dbs]$ scp initJASON.ora orapwJASON192.168.1.100:/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.

三、 备库配置
7. 创建对应目录
备库上创建相关目录
[oracle@jason2 oracle]$ mkdir -p /u01/app/oracle/admin/JASON2/adump
[oracle@jason2 oracle]$ mkdir -p /u01/app/oracle/admin/JASON/dpdump
[oracle@jason2 oracle]$ mkdir -p /u01/app/oracle/admin/JASON/pfile
