defines as a SID compared to a SERVICE_NAME, as we'll use this information to create a proper connection oracle listener refused the connection with the following error ora 12505 string later on. In Oracle, 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. 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 ora 12505 error in sql developer the SID followed by the database domain, like so: DB_UNIQUE_NAME.DB_DOMAIN 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
