Hi,

I tried to config two listeners on one box. The two listeners were started up successfully, but when I tried to tnsping them. One is called JZHAI responsed well, another one stdby1 told me reported me the above error.

Here is the content of listener.ora

The two files were changed by netasst. So the syntax should be fine.

Can someone help me !

Thanks

can you go to listener control utility, by going to command prompt and then typing lsnrctl

then give command status and post the output.

also try the commands (at lsnrctl prompt):
start stdby1

and post the output.
perhaps it might help..
