篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ADG搭建 基本款（主备完全一致）相关的知识，希望对你有一定的参考价值。
参考技术A 主库：192.168.204.101备库：192.168.204.109
软件安装路径主备库一样
SID主备库一样
主库已安装软件+实例
备库已安装软件
******************************
1.主库
强制归档模式
SQL> alter database force logging;
Database altered.
-----------------------------------------------------------------
创建standby redolog日志组：
首先查看有多少日志组：
SQL> select thread#,group#,bytes/1024/1024 from v$log;
THREAD# GROUP# BYTES/1024/1024
---------- ---------- ---------------
1 1 50
1 2 50
1 3 50
SQL> select * from v$logfile;
GROUP# STATUS TYPE MEMBER IS_
---------- ------- ------- ---------------------------------------------------------------------------------------------------- ---
1 ONLINE /home/oracle/oracleData/oracle/oradata/hrdb/redo01.log NO
2 ONLINE /home/oracle/oracleData/oracle/oradata/hrdb/redo02.log NO
3 ONLINE /home/oracle/oracleData/oracle/oradata/hrdb/redo03.log NO
其次添加日志组：
SQL> alter database add standby logfile group 4('/home/oracle/oracleData/oracle/oradata/hrdb/redo04.log') size 50m;
alter database add standby logfile group 5('/home/oracle/oracleData/oracle/oradata/hrdb/redo05.log') size 50m;
alter database add standby logfile group 6('/home/oracle/oracleData/oracle/oradata/hrdb/redo06.log') size 50m;
alter database add standby logfile group 7('/home/oracle/oracleData/oracle/oradata/hrdb/redo07.log') size 50m;
Database altered.
SQL>
Database altered.
SQL>
Database altered.
SQL>
Database altered.
--------------------------------------------------------------
密码文件创建
orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle force=y
---------------------------------------------------------------
修改LISTENER和TNSNAMES
LISTENER添加静态监听
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = hrdb)
(ORACLE_HOME = /home/oracle/oracleData/oracle/product/11.2.0/db_1)
(SID_NAME = hrdb)
)
)
TNSNAME
HRPRI =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.204.101)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = hrdb)
)
)
HRSTY =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.204.109)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = hrdb)
)
)
LISTENER和TNSNAMES和密码文件SCP至备库
listener因为主备库是完全一样的路径，可以不用修改
TNSNAMES，也不用修改
---------------------------------------------
备库：

************************************
3.PFILE修改
SQL> show parameter spfile
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /home/oracle/oracleData/oracle
/product/11.2.0/db_1/dbs/spfil
ehrdb.ora
SQL> create pfile from spfile;
File created.
pfile增加以下内容：
*.db_unique_name='hr_pri'
*.fal_server='hr_sty'
*.fal_client='hr_pri'
*.log_archive_config='dg_config=(hr_pri,hr_sty)'
*.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST valid_for=(all_logfiles,all_roles) db_unique_name=hr_pri'
*.log_archive_dest_2='service=hrsty LGWR ASYNC valid_for=(online_logfiles,primary_role) db_unique_name=hr_sty'
*.log_archive_dest_state_1='ENABLE'
*.log_archive_dest_state_2='ENABLE'
修改后要应用PFILE，一般是要重启
--------------
将修改后的pfile scp至备库，并进行以下修改
*.db_unique_name='hr_sty'
*.fal_server='hr_pri'
*.fal_client='hr_sty'
*.log_archive_config='dg_config=(hr_pri,hr_sty)'
*.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST valid_for=(all_logfiles,all_roles) db_unique_name=hr_sty'
*.log_archive_dest_2='service=hrsty LGWR ASYNC valid_for=(online_logfiles,primary_role) db_unique_name=hr_pri'
*.log_archive_dest_state_1='ENABLE'
*.log_archive_dest_state_2='ENABLE'
-----------
再根据pfile文件中的各路径进行mkdir
mkdir -p /home/oracle/oracleData/oracle/admin/hrdb/adump
mkdir -p /home/oracle/oracleData/oracle/oradata/hrdb/
mkdir -p /home/oracle/oracleData/oracle/fast_recovery_area/hrdb/
