Oracle Sql Error 12505

connect to the appropriate Oracle database, we'll need to expound a bit on how Oracle behaves and, therefore, what is causing this issue in the first place. SIDs vs SERVICE_NAMES It is important to ora 12505 error in sql developer understand the (slight) difference between what Oracle defines as a SID compared to a ora-12505 tns listener does not know of sid SERVICE_NAME, as we'll use this information to create a proper connection string later on. In Oracle, the system identifier (or SID) ora-12505 oracle 11g 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 listener refused the connection with the following error ora-12505 in oracle sql developer 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 The TNS Listener When a client is attempting
Listener Refused The Connection With The Following Error Ora-12514
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. Connection String With a bit more knowledge about how Oracle actually connects to databases, we can now look at how connection strings are formatted. Connect via TNS N

Re: ORA-12505, TNS:listener does not currently know of SID given in connect Eduardo Legatti Oct 8, 2006 3:48 PM (in response to 538177) Hi, Check to make sure that the SID is correct. The SIDs that are currently registered with the listener can be obtained by typing: LSNRCTL SERVICES on the Server These SIDs correspond to SID_NAMEs in TNSNAMES.ORA or DB_NAME in the initialization file.
