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 10gR2.0.1 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

[[email protected] oracle]$ cd $ORACLE_HOME/network/admin
[[email protected] admin]$ 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

[[email protected] admin]$ echo $ORACLE_SID
 ORCL

2、配置对应的tnsnames.ora 中的节点

[[email protected] 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

[[email protected] oracle]$ cat dbstart
lsnrctl start
sqlplus /nolog <<EOF
connect /as sysdba
startup
EOF
[[email protected] oracle]$ ./dbstart

可以看到

Service "WOO.COM" has 1 instance(s).

Instance "ORCL", status UNKNOWN, has 1 handler(s) for this service...

正在被监听。

4、验证该服务可以到达

[[email protected] oracle]$ tnsping WOOORCL

5、利用静态注册的服务登入oracle

[[email protected] oracle]$ sqlplus system/[email protected]

With the Partitioning, OLAP and Data Mining options
SQL> select count(*) from date_log;
  COUNT(*)

至此：已验证该静态注册可以成功的被解析，监听，连接。
