Oracle 静态监听注册详解

网上有很多关于Oracle 监听静态注册的文章，但大多都是简单说说，并没有详细的例子，这里，将结合Linux as4 下的Oracle 10gR2.0.

网上有很多关于Oracle 监听静态注册的文章，但大多都是简单说说，并没有详细的例子，这里，将结合Linux as4 下的Oracle 10gR2.0.1 举一个具体的例子。

1、在 $ORACLE_HOME/network/admin/listener.ora 文件中加入一个静态注册的节点

[oracle@prudent oracle]$ cd $ORACLE_HOME/network/admin
[oracle@prudent admin]$ vi listener.ora
# listener.ora Network Configuration File: /mydatafile2/app/oracle/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /mydatafile2/app/oracle/oracle/product/11.2.0/db_1)
(PROGRAM = extproc)
)

(SID_DESC =
(SID_NAME = ORCL)
(ORACLE_HOME = /mydatafile2/app/oracle/oracle/product/11.2.0/db_1)
(GLOBAL_DBNAME=WOO.COM)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = prudent)(PORT = 1521))
)
)

注意这里的GLOBAL_DBNAME=WOO.COM
SID_NAME=ORCL
这个SID_NAME 应与你对外提供服务的 $ORACLE_SID 一致

[oracle@prudent admin]$ echo $ORACLE_SID

ORCL

2、配置对应的tnsnames.ora 中的节点

[oracle@prudent admin]$ vi tnsnames.ora

# tnsnames.ora Network Configuration File: /mydatafile2/app/oracle/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
ORCL=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prudent)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL)
)
)

WOOORCL=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prudent)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = WOO.COM)
)
)

tnsname WOOORCL 中的 SERVICE_NAME=WOO.COM

这里的服务名为 WOO.COM 而不是通常的 ORCL，因为在 listener.ora 中已经注册了 WOO.COM,lsnrctl 启动时会监听 WOO.COM ，并对应到 SID_NAME=ORCL 上。

3、启动监听和服务

[oracle@prudent oracle]$ cat dbstart
lsnrctl start
sqlplus /nolog connect /as sysdba
startup
EOF
[oracle@prudent oracle]$ ./dbstart
