I can connect oracle by sqlplus. when I connect database by sqlplus,it send me a error ora-12560:tns.
but if I run the following command,it is ok:

set ORACLE_SID=oracle
oradim -startup -sid oracle -pfile 'f:\oracle\admin\oracle\pfile\init.ora'
sqlplus system/manager

but I can't run sqlplus direct.if i want to use sqlplus i must run the follow command

set ORACLE_SID=oracle
sqlplus system/manager
