Oracle 更改服务名方法

1.运行db的sqlplus：sqlplus sys/sys as sysdba （sys/sys为“用户名”/“密码”）

或配置client的监听后运行Client的sqlplus

2. （可省略）查看当前服务名：SQL> show parameter service_name

3. 修改服务名：SQL> alter system set service_names='orcl' scope=both;

4. 修改listener.ora（红色部分）：

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = E:\Oracle10g)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = ORCL)

(ORACLE_HOME = E:\Oracle10g)

(SID_NAME = ORCL)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

(ADDRESS = (PROTOCOL = TCP)(HOST = onest)(PORT = 1521))

)

)
