一、动态监听
1.监听文件
[oracle@node1 admin]$ more /u01/oracle/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/oracle)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
2.监听状态
[oracle@node1 admin]$ lsnrctl status

3.客户端tns文件[有部分测试加上了(UR=A)]
vm_asm =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.30)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = +ASM)
(INSTANCE_NAME = +ASM)
(UR=A) #分存在和不存在测试
)
)
vm_chf =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.30)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = chf)
(INSTANCE_NAME = chf)
)
)
4.无测试(UR=A)

二、静态监听
1.监听文件
[oracle@node1 admin]$ more listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = chf)
(ORACLE_HOME = /u01/oracle)
(SID_NAME = chf)
)
(SID_DESC =
(GLOBAL_DBNAME = +ASM)
(ORACLE_HOME = /u01/oracle)
(SID_NAME = +ASM)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.30)(PORT = 1521))
)
)
2.监听状态

3.无(UR=A)测试

5.easy connect访问asm实例
C:\Users\XIFENFEI>SQLPLUS sys/xifenfei@192.168.1.30/+asm as sysdba
SQL*Plus: Release 11.2.0.1.0 Production on 星期四 2月 23 22:27:42 2012

With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> select instance_name from v$instance;
INSTANCE_NAME
--------------------------------
+ASM
三、总结
1.在动态监听中，只有设置了(UR=A)才能够远程访问ASM实例；
2.在静态监听中，无论是否设置(UR=A)均可远程访问ASM实例，甚至可以使用easy connect方法方法ASM实例。
