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。

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

5、在primary端通过Rman Duplicate创建备库,在db01上执行如下命令

rman target sys/oracle@pri auxiliary sys/oracle@sty nocatalog
duplicate target database for standby from active database nofilenamecheck;

[oracle@db01 ~]$ rman target sys/oracle@pri auxiliary sys/oracle@sty nocatalog
