监听:
为客户端提供连接到服务器端的数据库的接口
一、使用netmgr工具配置监听:
(其他配置监听方式:
1 netca ,比较简单
2 直接修改配置文件
)
[oracle@oracle admin]$ netmgr
动态监听:
(数据库的pmon进程会自动注册到监听里面来,不过可能需要点时间(必需是默认监听listener))
(非默认监听的动态监听需要手工让数据库注册到监听:alter system set local_listener=‘(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.100.111)(PORT=1522))‘)
静态监听:(需要绑定数据库)
启动监听:
[oracle@oracle admin]$ lsnrctl start
#默认启动的监听是listener , 如果启动监听L1 则: lsnrctl start L1
Alias LISTENER

Listening Endpoints Summary...

Services Summary...
Service "fsdb" has 1 instance(s). # service name 在连接监听时需要用到
Instance "fsdb", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
通过监听使用命令连接服务器:
sqlplus system/123456@192.168.100.111:1521/fsdb
二、通过配置文件的方式连接服务:
创建tns配置文件:
下一步选择协议:省略
连接服务器:
[oracle@oracle admin]$ sqlplus system/123456@f1 #f1上面配置tns时第一步设置的
三、通过修改配置文件手工配置监听:
通过图形化配置监听和tns实质上就是修改配置文件:
$ORACLE_HOME/network/admin/ 目录下的文件 listener.ora (监听配置文件) tnsnames.ora(tns配置文件)
配置文件例子:
监听多个实例的例子:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = RROD4)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = PROD4)
)
(SID_DESC =
(GLOBAL_DBNAME = EMREP)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = EMREP)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = edsir1p8.us.oracle.com)(PORT = 1521))
)
ADR_BASE_LISTENER = /u01/app/oracle
监听不同端口的例子:
L1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = edsir1p8.us.oracle.com)(PORT = 1522))
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = PROD4)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = PROD4)
)
)
ADR_BASE_L1 = /u01/app/oracle
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = edsir1p8.us.oracle.com)(PORT = 1521))
)
ADR_BASE_LISTENER = /u01/app/oracle
SID_LIST_L1 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = PROD4-1522)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = PROD4)
)
)
tns配置文件:
P4 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.190.104.28)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = PROD4.us.oracle.com)
)
)
