如何修改 service_name

oracle之修改服务名

如何修改 service_name原有环境：

sid： mynewdb
global_name：mynewdb
service_names： MYNEWDB
db_domain  ： 
db_name：mynewdb

需要修改如下：

global_name：mynewdb
service_names： test
db_domain  ： 
db_name：mynewdb

服务器端：

alter system set service_names='test';

这里采用静态注册，同时还要修改下 listener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME =/u01/app/oracle/product/11.2.0/dbhome_1)
      (PROGRAM = extproc)
    )
        (SID_DESC=
        (GLOBAL_DBNAME = mynewdb)
        (ORALCE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
        (SID_NAME = mynewdb)
        )
        (SID_DESC=
        (GLOBAL_DBNAME = test)  -------这个是需要添加
        (ORALCE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
        (SID_NAME = mynewdb)    ------这个还是原来的实例名
        )
  )

cmd下执行命令lsnrctl reload

查看监听状态lsnrctl status

LSNRCTL>

可以看到新的 Service "test" 已经可以使用了

客户端配置：

net manager 配置 服务名为 test ，ip为数据库服务器主机ip，相应端口。

测试连接：

SQL>  conn sys/oracle@test as sysdba
已连接。
SQL>

当然不使用静态注册，动态注册也可以
