In our previous blog We have seen about the error message related to the address of tnsnames.ora file.
In this blog we will see the location of listener.ora and tnsnames.ora file . listener.ora is the database server level file and tnsnames.ora is the client side file.
oracle listener service should be up and running to get the new connection to oracle database.
In this blog, I will show you how to check the location of listener.ora and tnsnames.ora file in database server.
if your listener is up and running then you can get the both file path from there.
- Check the listener status.
