oracle动态注册和静态注册监听器

oracle动态注册和静态注册的区别：动态监听不需要在listener.ora文件中记录关于数据的任何信息，只需要将监听器的配置信息写入到该文件。例如：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS=(PROTOCOL = IPC) (KEY=EXTPRO1))
(ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
)
客户端的tnsnames.ora配置信息，需要加入每个service_name,其他的任何东西不需要改动，例如
YUCESHI1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = test1)
)
)
YUCESHI2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = test2)
)
)
YUCESH3 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = test3)
)
)

动态监听步骤：
服务器端配置如下：

设置service_names:

alter system set service_names=test1,test2,test3;
2. 编写listener.ora文件：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS=(PROTOCOL = IPC) (KEY=EXTPRO1))
(ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
)
3.重新启动oracle实例，这样做才能使service_names生效。（前提是oracle处于open状态下才执行）
conn /as sysdba;

shutdown immediate;
startup;
客户端配置：
1.编辑tnsnames.ora,保存后立即生效。
YUCESHI1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = test1)
)
)
YUCESHI2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = test2)
)
)
YUCESH3 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = test3)
)
)

以上动态注册配置完毕。以上改为静态注册步骤。
1.只需要在服务器端修改listener.ora配置文件。并且多几个SID_DESC就行了。

配置如下：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS=(PROTOCOL = IPC) (KEY=EXTPRO1))
(ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.2.29)(PORT = 1521))
)
)
##上面是监听器配置部分，下面是数据库配置部分
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = test1)
(ORACLE_HOME = /opt/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl )
)
(SID_DESC =
(GLOBAL_DBNAME = test2)
(ORACLE_HOME = /opt/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl )
)
(SID_DESC =
(GLOBAL_DBNAME = test3)
(ORACLE_HOME = /opt/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl )
)
)
2.重新启动监听：
su - oracle
lsnrctl stop
lsnrctl start
配置完成
