再次同时配置动态监听与静态监听：
oracle机ORA11GR2库：192.168.2.4
enmo机PROD库：192.168.2.6

----oracle机ORA11GR2库：192.168.2.4

--动态监听：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =oracle)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

ADR_BASE_LISTENER = /u01/app/oracle

--静态监听：
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=ORA11GR2)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)

)

--两种监听配置完毕，启动ORA11GR2库监听或者查看监听的状态：

可以看到动态监听与静态监听配置有效。

另外使用enmo机本机的连接串“12”连接oracle机ORA11GR2库就不在这里演示了，同样的方法连接就可以了。
