Oracle 静态监听注冊具体解释

Oracle 静态监听注冊具体解释

网上有非常多关于oracle 监听静态注冊的文章。但大多都是简单说说，并没有具体的样例。这里，将结合linux as4 下的oracle 10gR2.0.1 举一个具体的样例

1、在 $ORACLE_HOME/network/admin/listener.ora 文件里增加一个静态注冊的节点

[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、配置相应的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，由于在 listener.ora 中已经注冊了 WOO.COM,lsnrctl 启动时会监听 WOO.COM 。并相应到 SID_NAME=ORCL 上。



3、启动监听和服务

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

能够看到

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

正在被监听。

4、验证该服务能够到达

[oracle@prudent oracle]$ tnsping WOOORCL

5、利用静态注冊的服务登入oracle

[oracle@prudent oracle]$ sqlplus system/oracle@WOOORCL

至此：已验证该静态注冊能够成功的被解析，监听，连接。
