RAC DATAGUARD primary listener

这一步最为关键，一定要设置成静态监听，因为动态监听在rman连接时监听状态会立马变成locked，静态监听的状态一般是UNKNOWN

Service "PRODS" has 1instance(s).

Instance "PROD", status UNKNOWN, has 1 handler(s) for this service...

The command completed successfully

然后监听这块有问题的话一定会报下面的的错：

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID=54 instance=PROD1device type=DISK

下面的lsnrctl status 报错要去查看service name和参数文件是否一致

主库：

主库的监听是grid在管理，但tns会在oracle下

[oracle@node1 ~]$ cd$ORACLE_HOME/network/admin

[oracle@node1 admin]$ pwd

其实就是这么个东西，我们打开看一下：

[oracle@node1 admin]$ cat tnsnames.ora

我们再去grid下面看真正的监听

[grid@node1 ~]$ cd$ORACLE_HOME/network/admin

[grid@node1 admin]$ pwd

/u01/11.2.0/ghome/network/admin

[grid@node1 admin]$

[grid@node1 admin]$ ll

[grid@node1 admin]$

这里面的tnsname.ora没什么东西，估计是连接自己的库用的

我们看一下就知道了

[grid@node1 admin]$ cat tnsnames.ora

# tnsnames.ora.node1 Network ConfigurationFile: /u01/11.2.0/ghome/network/admin/tnsnames.ora.node1

(ADDRESS = (PROTOCOL = TCP)(HOST = node2)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = PROD)

)

)

[grid@node1 admin]$

下面我们看listener.ora

[grid@node1 admin]$ cat listener.ora

# listener.ora Network Configuration File:/u01/11.2.0/ghome/network/admin/listener.ora

# Generated by Oracle configuration tools.

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1= ON

SID_LIST_LISTENER =

(SID_LIST=

(SID_DESC =

(GLOBAL_DBNAME = PROD1)

(ORACLE_HOME = /u01/11.2.0/ghome)

(SID_NAME = PROD)

)

)

LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = LISTENER))

)

ADR_BASE_LISTENER = /u01/11.2.0/gbase

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER= ON

LISTENER_SCAN1 =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = LISTENER_SCAN1))

)

ADR_BASE_LISTENER_SCAN1 = /u01/11.2.0/gbase

[grid@node1 admin]$

注：这个监听是安装建库时oracle自己建立的，但我后来有手动添加了静态监听，方法如下：

当然我们可以先netca

[grid@node1 admin]$ netmgr



点击你的监听配置，然后选择database services

这里Global Database Name 即是你的实例名



SID就是你的库名喽



当然上面的监听你还要注意这么一句
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER= ON
[grid@node1 admin]$ catendpoints_listener.ora

LISTENER_NODE1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=node1vip)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.56.10)(PORT=1521)(IP=FIRST)))) # line added by Agent
[grid@node1 admin]$
这也是grid监听重要的一部分
