Oracle静态监听注册详解

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

[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) ) ) [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 <<EOF connect /as sysdba startup EOF [oracle@prudent oracle]$ ./dbstart LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 13-FEB-2011 20:11:15 Copyright (c) 1991, 2005, Oracle.  All rights reserved.

The command completed successfully SQL*Plus: Release 11.2.0.1.0 - Production on Sun Feb 13 20:11:16 2011 Copyright (c) 1982, 2005, Oracle.  All rights reserved. SQL> Connected to an idle instance.

　　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

[oracle@prudent oracle]$ tnsping WOOORCL TNS Ping Utility for Linux: Version 11.2.0.1.0 - Production on 13-FEB-2011 20:14:59 Copyright (c) 1997, 2005, Oracle.  All rights reserved. Used parameter files: /mydatafile2/app/oracle/oracle/product/11.2.0/db_1/network/admin/sqlnet.ora Used TNSNAMES adapter to resolve the alias Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = prudent)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = WOO.COM))) OK (10 msec)

　　5、利用静态注册的服务登入oracle

[oracle@prudent oracle]$ sqlplus system@oracleWOOORCL SQL*Plus: Release 11.2.0.1.0 - Production on Sun Feb 13 20:17:27 2011 Copyright (c) 1982, 2005, Oracle.  All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 11.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options SQL> select count(*) from date_log; COUNT(*) ---------- SQL>

　　至此：已验证该静态注册可以成功的被解析，监听，连接。
