Oracle RAC 验证以及Oracle 11G R2 启动与关闭


在前段时间已经安装完rac，那么安装完成后，要做的就是验证Rac是否是正确安装以及如何启动与关闭Rac。今天开始学习Rac，再次记录一下笔记！

  第一：验证RAC：

    验证监听：

node 1：

SQL> show parameter local_listener

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (ADDRESS=(PROTOCOL=TCP)(HOST=
192.168.4.114)(PORT=1521))
SQL> show parameter remote_listener

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
remote_listener string rac-two-cluster-scan.grid.exam
ple.com:1521
SQL>

 

node 2：

SQL> show parameter local_listener

NAME TYPE VALUE
------------------------------------ ---------- ------------------------------
local_listener string (ADDRESS=(PROTOCOL=TCP)(HOST=
192.168.4.113)(PORT=1521))
SQL> show parameter remote_listener

NAME TYPE VALUE
------------------------------------ ---------- ------------------------------
remote_listener string rac-two-cluster-scan.grid.exam
ple.com:1521
SQL>

                                                ple.com:1521
SQL> !lsnrctl status

注： 

LOCAL_LISTENER

PropertyDescription
Parameter type String
Syntax LOCAL_LISTENER =network_name
Default value (ADDRESS = (PROTOCOL=TCP)(HOST=hostname)(PORT=1521))wherehostnameis the network name of the local host.
Modifiable ALTER SYSTEM
Basic No

LOCAL_LISTENERspecifies a network name that resolves to an address or address list of Oracle Net local listeners (that is, listeners that are running on the same machine as this instance). The address or address list is specified in theTNSNAMES.ORAfile or other address repository as configured for your system.

 

REMOTE_LISTENER

PropertyDescription
Parameter type String
Syntax REMOTE_LISTENER =network_name
Default value There is no default value.
Modifiable ALTER SYSTEM
Basic Yes

REMOTE_LISTENERspecifies a network name that resolves to an address or address list of Oracle Net remote listeners (that is, listeners that are not running on the same machine as this instance). The address or address list is specified in theTNSNAMES.ORAfile or other address repository as configured for your system.

也就是说：local_listener是单主机服务器本地监听，remote_listener是oracle网络远程监听器也就是scan vip的监听参数。
