Oracle DB设置动态实例注册

DB安装完成后，可能会出现不能自动动态注册的情况。此时通过口令身份验证时（即：sqlplus system/xxx@test登录时），会报出ora-12514的错误。当然，此时可以设置静态注册来解决该问题。静态注册：在listener.ora文件中添加下面的句子。(SID_DESC = (GLOBAL_DBNAME = test) -- dbname (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1) -- ORACLE_HOME的路径 (SID_NAME = test) -- SID的名字)
本文介绍如何设置动态注册。动态注册：设置实例参数local_listener
首先，查看tnsnames.ora文件中的相关实例的tns。 [oracle@OracleServer admin]$ cat ./tnsnames.ora TEST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = TOracle)(PORT = 1521)) ) （HOST必须在/etc/hosts里有设置）其次，用系统验证的方法（即：sqlplus / as sysdba）登录DB。
再次，修改系统，设置参数local_listener为TEST（tnsnames.ora里面的）。 [oracle@OracleServer admin]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.3.0Production on Tue Dec 17 04:26:21 2013 Copyright (c) 1982, 2011,Oracle.

最后，重启监听器，重启实例。[oracle@OracleServeradmin]$ lsnrctl statusLSNRCTLfor Linux: Version 11.2.0.3.0 - Production on 17-DEC-2013 04:47:11Copyright(c) 1991, 2011, Oracle. All rightsreserved.
