最近本地环境上安装了timesten，设置了一些环境变量，直接导致本地的sqlplus连不上数据库了，做了一些测试：
缺失环境变量:
oracle_sid ora11
NS_ADMIN F:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN

改SID_NAME为ora11，重启监听
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = F:\app\Administrator\product\11.2.0\dbhome_1)

)
两种方式都可以成功。
总结一下：
缺失TNS_ADMIN，sqlplus test/test可以成功。
缺失oracle_sid，sqlplus test/test@ora112可以成功。
缺失TNS_ADMIN，oracle_sid，两个都不成功。
listener.ora SID_NAME错误，sqlplus test/test可以成功。
说明oracle_sid对sqlplus test/test有直接影响。TNS_ADMIN，listener.ora对sqlplus test/test@ora112有直接影响。
listener.ora中的sid_name要与tnsname.ora中的SERVICE_NAME一致。
listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = ora11)
(ORACLE_HOME = F:\app\Administrator\product\11.2.0\dbhome_1)
