important to understand the (slight) difference between what Oracle defines as a SID ora 12505 tns listener could not resolve sid compared to a SERVICE_NAME, as we'll use this information to create a proper connection string later on. In Oracle,
Ora 12505 Tns Listener Does Not Currently Know Of Sid
the system identifier (or SID) is a local identifier of up to eight characters in length that is used to identify a particular database and differentiate it from other databases on the system. ora 12505 tns listener does not currently know sid given Often the SID is the prefix word or DB_UNIQUE_NAME that precedes the DB_DOMAIN. For example, the SID of our bookstore database, as seen in in the full global database name of bookstore.company.com. SERVICE_NAMES, on the other hand, represent the names by which database instances can be connected to. A SERVICE_NAME will typically follow the format of the SID followed by the database domain, like so: DB_UNIQUE_NAME.DB_DOMAIN ora 12505 error in sql developer The TNS Listener When a client is attempting to connect to an Oracle database, rather than connecting to the database directly, there is a broker service that intervenes and handles the connection request for the client. This broker application is known as the listener and it performs the task of listening for incoming client requests. When a request is received, the listener processes and forwards that request onto the appropriate Oracle database server using a service handler, which just acts as the connection between the listener and the database server. TNS Names and Configuration When connecting to an Oracle database, typically your database server will have tnsnames.ora, which is a configuration file that informs the server about NET_SERVICE_NAMES which are valid database connections. By default, this file is located at ORACLE_HOME/network/admin. For example, a NET_SERVICE_NAME descriptor in tnsnames.ora may be formatted like this: myDatabaseNetService = (DESCRIPTION = (ADDRESS = (PROTOCOL = tcp)(HOST = localhost)(PORT = 1521)(QUEUESIZE = 100)) (CONNECT_DATA = (SERVICE_NAME = bookstore.company.com) ) ) This would define a NET_SERVICE_NAME using the SERVICE_NAME we discussed earlier (bookstore.company.com) and connecting to localhost through port 1521.

ORA-12502: TNS:listener received no CONNECT_DATA from client Cause: No CONNECT_DATA was passed to the listener. Action: Check that the service https://chartio.com/resources/tutorials/how-to-fix-ora-12505-tns-listener-does-not-currently-know-of-sid-given-in-connect-descriptor name resolved from TNSNAMES.ORA has the CONNECT_DATA component of the connect descriptor. ORA-12504: TNS:listener was not given the SID in CONNECT_DATA Cause: The SID was missing from the CONNECT_DATA. Action: Check that the connect descriptor corresponding to the service name in TNSNAMES.ORA has an SID component in the CONNECT_DATA. ORA-12505: TNS:listener does not currently know of SID given in connect descriptor Cause: The listener https://docs.oracle.com/cd/B19306_01/server.102/b14219/net12500.htm received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a SID for an instance (usually a database instance) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener. Action: - Wait a moment and try to connect a second time. - Check which instances are currently known by the listener by executing: lsnrctl services
