由于环境限制，现在需要把2套rac集群通过dg复制指向远端的单机多实例上面。
rac指向第一个实例的前面已经有文档
这里直接添加第二个实例的复制搭建，主要标出不同地方
SQL*Plus: Release 11.2.0.4.0 Production
基本步骤与上面相同，只是实例名有不同之处
1 主库rac集群，设置为归档，和force logging模式
2 主库添加 standby Redo log 文件
3 主备库修改listener.ora 和tnsnames.ora 文件
主库与之前基本相同
备库
[oracle@dg1 admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcl)
)
(SID_DESC =
(GLOBAL_DBNAME = cad)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = cad) ---在主机dg1上 ，添加2个实例
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dg1)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
[oracle@dg1 admin]$ cat tnsnames.ora
bol=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.15)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.16)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME =bol)
)
)
orcl=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.30)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME =orcl)
)
)
cad=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.30)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME =cad)
)
)
[oracle@rac07 ~]$ tnsping cad
4 在备库创建相应的目录
mkdir -p /u01/app/oracle/fast_recovery_area/cad
mkdir -p /u01/app/oracle/oradata/cad/data
mkdir -p /u01/app/oracle/oradata/cad/tempfile
mkdir -p /u01/app/oracle/admin/cad/adump
mkdir -p /u01/app/oracle/admin/cad/data
mkdir -p /u01/app/oracle/admin/cad/redo
mkdir -p /u01/app/oracle/admin/cad/tempfile
mkdir -p /u01/app/oracle/archive/cad
5 修改主备库参数和把主库密码文件cp到备库
--备库参数文件

6 使用 spfile 将备库启动 nomount 状态并启动监听
7 备库进行duplicate
export ORACLE_SID=cad
rman target sys/****@10.*.29/bol auxiliary sys/****@cad nocatalog
8 开启dg复制
