一、环境介绍:
我在db01和db02两台Linux虚拟机上首先分别安装了一套数据库软件，在db01主机上创建了名为woo的数据库；我们这次的实验是要搭建了一套Oracle 11g Active DataGuard；目的是为了实现数据库同步的功能，并且了解Oracle 11g DG的基本功能。

db02:192.168.1.51

二、11g ADG部署：
1、pri端和sty端配置静态监听
[oracle@sty admin]$ cat listener.ora
# listener.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = Woo )
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
)
)
[oracle@sty admin]$cat tnsname.ora
# tnsnames.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
STY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.51)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = woo)
)
)
PRI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.50)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = woo)
)
)
2、修改primary端初始化参数文件
startup mount;
alter database archivelog;
alter database force logging;
alter database open;
alter system set log_archive_config = 'DG_CONFIG=(pri,sty)' scope=spfile;
alter system set log_archive_dest_1 = 'LOCATION=/DBBackup/Archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=pri' scope=spfile;
alter system set log_archive_dest_2 = 'SERVICE=sty LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=sty' scope=spfile;
alter system set log_archive_dest_state_1 = ENABLE;
alter system set log_archive_dest_state_2 = ENABLE;
alter system set fal_server=sty scope=spfile;
alter system set fal_client=pri scope=spfile;
alter system set standby_file_management=AUTO scope=spfile;
3、在primary端pfile参数文件和密码文件，并且拷贝到standby段相应位置
SQL> create pfile from spfile;
File created.
[oracle@db01 dbs]$ scp initwoo.ora orapwwoo db02:/DBSoft/oracle/product/11.2.4/dbhome_1/dbs
oracle@192.168.1.51's password:
initwoo.ora 100% 1260 1.2KB/s 00:00
orapwwoo 100% 1536 1.5KB/s 00:00
[oracle@db01 oracle]$ scp -r admin/ diag/ fast_recovery_area/ oradata/ 192.168.1.51:$ORACLE_BASE
oracle@192.168.1.51's password:
init.ora.512201522543 100% 1778 1.7KB/s 00:01
dp.log 100% 116 0.1KB/s 00:00
........
4、修改standby端的监听文件及初始化参数文件
--修改监听文件
[oracle@db02 ~]$ cd $ORACLE_HOME/network/admin
[oracle@db02 admin]$ vi listener.ora
# listener.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = db02)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = woo)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
(SID_NAME = woo)
)
)
ADR_BASE_LISTENER = /DBSoft/oracle
--启动监听
[oracle@db02 dbs]$ lsnrctl start

6、在primary 和standby端添加standby日志
SQL> alter database add standby logfile
group 4 ('/DBSoft/oracle/oradata/woo/styredo04.log') size 50m,
group 5 ('/DBSoft/oracle/oradata/woo/styredo05.log') size 50m,

group 7 ('/DBSoft/oracle/oradata/woo/styredo07.log') size 50m;
SQL> SELECT GROUP#,THREAD#,SEQUENCE#,ARCHIVED,STATUS FROM V$STANDBY_LOG;
GROUP# THREAD# SEQUENCE# ARC STATUS
---------- ---------- ---------- --- ----------

5 0 0 YES UNASSIGNED
6 0 0 YES UNASSIGNED
7 0 0 YES UNASSIGNED
7、在standby端开启实时日志应用

Media recovery complete.
