This article mainly introduces how to solve the problems that navicat listeners can not identify at present, which has a certain reference value, and friends who need it can refer to it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

When connecting to oracle with navicat, the program reports an error and prompts: "ORA-12514, TNS:listener does not currently know of service requested in connect descriptor". After checking, it is because the name of service is misspelled.

Solution:

The first step is to find tnsnames.ora in the oracle installation directory.

(example directory of tnsnames.ora: d:\ oracle\ product\ 10.2.0\ db_1\ network\ admin\ tnsnames.ora)

The second step is to find service_name in tnsnames.ora, which is the service name that navicat needs to fill in when connecting to the database:

The third step is to enter the corresponding service_name in the connection properties of navicat, as well as host, username, password, etc., which should be able to connect successfully.
