sqlplus只能远程登陆
本机实例监听都启动了,PL/SQL中SCOTT及其他账户均可登陆,sqlplus中就不行:
SQL code

C:\Users\e>sqlplus/nolog

SQL*Plus: Release 10.2.0.3.0 - Production on 星期三 8月 1 12:49:03 2012

Copyright (c) 1982, 2006, Oracle.  All Rights Reserved.

SQL> connect scott
输入口令:
ERROR:
ORA-12560: TNS: 协议适配器错误


为什么改为远程登陆就可以了呢,原来不这样的呀 
SQL code

C:\Users\e>sqlplus scott/scott@localhost:1521/orcl

SQL*Plus: Release 10.2.0.3.0 - Production on 星期三 8月 1 12:50:14 2012

Copyright (c) 1982, 2006, Oracle.  All Rights Reserved.


连接到:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production
With the Partitioning, OLAP and Data Mining options


ORA文件:
XML code

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = e-PC)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )



------解决方案--------------------
此问题可能是oracle_sid没有设置或者设置错误导致的.
解决办法:
cmd命令行上:
C:\> set ORACLE_SID=instance名字
