Thank you so much.
I have reconfigure my tnsname.ora,and it is ok.
you are really expert .
我还想问的是在window ,service ,start my oracle<sid>service,和
用startup pfile="....."是不是再干同一件事
因为上学期我是在学校的机器上use oracle,everytime I just telnet the host , connect to as internal, then startup an instance,
but now I install an oracle in my own machine,so I wonder if the manulely starting the service is equal to use that statement"startup pfile=.....".
