DATAGUARD搭建
1. 二節點RAC+singledg
1. 修改歸檔
2. 準備備庫

3.配置主備庫的監聽，修改tnsnames.ora和 listener.ora 文件
WXXRDB2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =dbs-vip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = wxxrdb)
(INSTANCE_NAME = wxxrdb2)
)
)
LISTENERS_WXXRDB=
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =dbp-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST =dbs-vip)(PORT = 1521))
)
WXXRDB1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =dbp-vip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = wxxrdb)
(INSTANCE_NAME = wxxrdb1)
)
)
WXXRDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =dbp-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST =dbs-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = wxxrdb)
)
)
WXXRDB_ST=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.1.106)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = wxxrdb)
)
)
4．在主庫上創建備庫的密碼文件和控制文件，並將文件傳到備庫的相關位置
[oracle@dbp admin]$ orapwdfile=$ORACLE_HOME/dbs/orapwwxxrdb password=s123456
[oracle@dbp admin]$ cd $ORACLE_HOME/dbs
[oracle@dbp dbs]$ ls
ab_+ASM1.dat hc_+ASM1.dat hc_wxxrdb1.dat init+ASM1.ora initdw.ora init.ora initwxxrdb1.ora orapw+ASM1 orapwwxxrdb orapwwxxrdb1
[oracle@dbp dbs]$ scp orapwwxxrdb192.168.1.106:/opt/oracle/product/10.2.0/db_1/dbs

5.修改參數文件
1.修改rac參數文件，修改後如下

2．修改standby數劇庫參數文件
