Usando l'alias TNS con OJDBC 12.1

Question

Sto deliberando un'applicazione Java che deve accedere a un database Oracle.Finora ho usato il driver OJDBC6 senza problemi.Ora stiamo cambiando i database su Oracle 12C, quindi volevo utilizzare il nuovo driver JDBC.

Questo è il codice

public class jdbctest {  
  public static void main(String[] args) throws Exception {  
  final PoolDataSource pds = PoolDataSourceFactory.getPoolDataSource();  
  oracle.jdbc.OracleDriver.main(args);  
  System.setProperty("oracle.net.tns_admin", "c:/Windows/System32/oracle-home/network/admin");  
  pds.setConnectionFactoryClassName("oracle.jdbc.pool.OracleDataSource");  
  pds.setURL("jdbc:oracle:thin:@TNSALIASWITHOUTDOTS");  
  System.out.println("Opening connection...");  
  final Connection connection = pds.getConnection();  
  System.out.println("Connection opened");  
  }  
}  

.

Questo è il TNSNames.ora (Host è cambiato, perché è qualcosa nella nostra intranet)

TNSALIAS.WITH.DOTS  = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = testdomain.de) (PORT = 1521)))(CONNECT_DATA = (SID = EDISW) ))  
TNSALIASWITHOUTDOTS  = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = testdomain.de) (PORT = 1521)))(CONNECT_DATA = (SID = EDISW) ))  

.

Questa è l'uscita per tutte e quattro le varianti (2 driver, 2 tnsias) JDBC 11.2, TNSAIASWithOutdots

Per coloro che non conoscono tedesco, ora-01017 significa "Nome utente / password non valido"

Ciò significa che ogni combinazione tranne 12.1 con punti nell'alias TNS è in grado di connettersi al database.Qualche suggerimento?

Answer 1

Abbiamo scoperto che questo è un bug nel driver JDBC 11.2.0.4 e in poi.Creeremo un bugreport a Oracle.

La soluzione alternativa sarebbe quella di utilizzare gli alias TNS senza punti nel loro nome.
