1、修改监听
主库：
修改tnsnames.ora：
primary1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.143.53.31)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = primary1)
)
)
standsty1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.143.53.33)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = standsty1)
)
)
修改listener.ora：
SID_LIST_LISTENER=
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME= primary1)
(ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db)
(SID_NAME=primary1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY =EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.143.53.31)(PORT = 1521))
)
)
备库：
修改tnsnames.ora：
primary1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.143.53.31)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = primary1)
)
)
standsty1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.143.53.33)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = standsty1)
)
)
修改listener.ora：
SID_LIST_LISTENER=
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME= primary1)
(ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db)
(SID_NAME=standsty1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY =EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.143.53.33)(PORT = 1521))
)
)
2、主库设置归档：
开启归档
SQL> alter database archivelog;
Database altered.
设置归档路径
SQL> alter system set log_archive_dest_1='location=+DG_ARCH' scope=both;
System altered.
切换日志
SQL> alter system archive log current;
System altered.
查询归档日志
ASMCMD> ls -l
Type Redund Striped Time Sys Name
ARCHIVELOG UNPROT COARSE JUN 20 20:00:00 Y thread_1_seq_1.256.915051109
ARCHIVELOG UNPROT COARSE JUN 20 20:00:00 Y thread_1_seq_2.257.915051111
ARCHIVELOG UNPROT COARSE JUN 20 20:00:00 Y thread_1_seq_3.258.915051231
3、主库设置force logging模式
SQL> alter database force logging;
Database altered.
4、主库修改参数文件
SQL> create pfile='/oracle/app/oracle/product/11.2.0/db/dbs/initprimary1.ora' from spfile;
File created.
修改pfile文件 /oracle/app/oracle/product/11.2.0/db/dbs/initprimary1.ora，增加以下内容
*.db_name=primary1
*.db_unique_name=primary1
*.dispatchers='(PROTOCOL=TCP) (SERVICE=primary1XDB)'
*.fal_client='primary1'
*.fal_server='standsty1'
*.log_archive_config='DG_CONFIG=(primary1,standsty1)'
*.log_archive_dest_1='LOCATION=+DG_ARCH VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=primary1'
*.log_archive_dest_2='SERVICE=standsty1 OPTIONAL LGWR SYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=standsty1'
*.log_archive_dest_state_1='ENABLE'
*.log_archive_dest_state_2='ENABLE'
*.log_archive_format='%t_%s_%r.arc'
*.standby_file_management=auto
*.log_archive_max_processes=30
*.db_file_name_convert='standsty1','primary1'
*.log_file_name_convert='standsty1','primary1'
以spfile启动数据库
SQL> shutdown immediate

Database dismounted.
ORACLE instance shut down.
SQL> startup pfile='/oracle/app/oracle/product/11.2.0/db/dbs/initprimary1.ora'

------------------------------------ ----------- ------------------------------
spfile string +DG_DATA1/primary1/spfileprimary1.ora
5、拷贝主库的pfile和密码文件到备库上
[ythisbilldbn1] cd /oracle/app/oracle/product/11.2.0/db/dbs/
[ythisbilldbn1] scp initprimary1.ora 10.143.53.33:/oracle/app/oracle/product/11.2.0/db/dbs
[ythisbilldbn1] scp orapwprimary1 10.143.53.33:/oracle/app/oracle/product/11.2.0/db/dbs
6、备库修改参数文件
修改从主库拷贝过来的pfile文件 /oracle/app/oracle/product/11.2.0/db/dbs/initprimary1.ora，替换以下内容
*.audit_file_dest='/oracle/app/oracle/admin/standsty1/adump'
*.db_name=primary1
*.db_unique_name=standsty1
*.dispatchers='(PROTOCOL=TCP) (SERVICE=standsty1XDB)'
*.fal_client='standsty1'
*.fal_server='primary1'
*.log_archive_config='DG_CONFIG=(standsty1,primary1)'
*.log_archive_dest_1='LOCATION=+DG_ARCH VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=standsty1'
*.log_archive_dest_2='SERVICE=primary1 OPTIONAL LGWR SYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=primary1'
*.log_archive_dest_state_1='ENABLE'
*.log_archive_dest_state_2='ENABLE'
*.log_archive_format='%t_%s_%r.arc'
*.standby_file_management=auto
*.log_archive_max_processes=30
*.db_file_name_convert='primary1','standsty1'
*.log_file_name_convert='primary1','standsty1'
7、在主库通过Rman Duplicate创建备库，主库执行
[ythisbilldbn1:oracle:/home/oracle]rman target sys/xxxxxx@primary1 auxiliary sys/xxxxxx@standsty1 nocatalog

8、备库增加4组备用日志
SQL> alter database add standby logfile
group 5 size 5G,
group 6 size 5G,
group 7 size 5G,
group 8 size 5G;
#因每组两个成员，增加备用日志的成员#
SQL> alter database add standby logfile member '+DG_DATA1' to group 5;
SQL> alter database add standby logfile member '+DG_DATA1' to group 6;
SQL> alter database add standby logfile member '+DG_DATA1' to group 7;
SQL> alter database add standby logfile member '+DG_DATA1' to group 8;
#查看日志文件是否添加成功#
SQL> select group#, member from v$logfile;
9、在备库开启到read only状态
#查看当前备库状态为MOUNTED#
SQL> select open_mode,database_role,db_unique_name from v$database;
OPEN_MODE DATABASE_ROLE DB_UNIQUE_NAME
-------------------- ---------------- ------------------------------
MOUNTED PHYSICAL STANDBY standsty1
#关闭数据库#
SQL> shutdown immediate
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
#启动数据库#
SQL> startup
ORACLE instance started.
Total System Global Area 4.2758E+10 bytes

Variable Size 2.0670E+10 bytes
Database Buffers 2.1475E+10 bytes
Redo Buffers 611299328 bytes

#查看数据库状态，为read only只读模式#
SQL> select open_mode,database_role,db_unique_name from v$database;
OPEN_MODE DATABASE_ROLE DB_UNIQUE_NAME
-------------------- ---------------- ------------------------------
READ ONLY PHYSICAL STANDBY standsty1
10、在备库开启实时日志应用
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
Database altered.
#取消实时日志应用的语句#
--ALTER DATABASE RECOVER MANAGED STANDBY DATABASE cancel;
#查看备库是否应用redo，主备库查命令#
select sequence#,applied from v$archived_log where DEST_ID=2 order by sequence#;
-------------------至此 ADG已基本搭建完毕
11、主库、备库 的删除归档日志策略，用rman配置 CONFIGURE ARCHIVELOG DELETION POLICY 参数
#NONE ：设置为该值时，则不启用归档文件的删除策略。默认情况下就是NONE#
#主库设置 SHIPPED TO ALL STANDBY ：设置为该值时，当归档传送到备库就可以删除#
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO ALL STANDBY;
new RMAN configuration parameters:
CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO ALL STANDBY;
new RMAN configuration parameters are successfully stored
#备库设置 APPLIED ON STANDBY ：设置为该值时，会强制检查待删除的log 是否已经在备库apply，只有apply后的log才能删除#
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
new RMAN configuration parameters:
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
new RMAN configuration parameters are successfully stored
#删归档日志#
RMAN> delete archivelog all
/*设置自动删除归档日志 crontab
