When I installed oracle yesterday, I found that an unlistener error occurred when using pl/sql! Look up a lot of information on the Internet! It's all about changing the listening file, listener.ora file. But after I changed it, I still couldn't listen. I really don't understand! Then I just uninstalled the program!

But feel that every time there is such a mistake, reloading is not a good way! Finally, I found a way. I don't know if there is such a way on the Internet! I haven't found it yet! So write this blog in the hope that it can help you all! Of course, I use 11g. I don't know if other versions can be changed in this way! But I think it's all the same!

Find oracle 11g home_1 > > configuration and Migration tools in all programs on the start menu

Open Net Manager under the migration tool catalog

Select oracle Net to configure the local listener LISTENER

Change the hostname to localhost or 127.0.0.1
