Base de données Oracle Express via JDBC en utilisant un UCP (Universal Connection Pool)

Question

J'utilise Oracle Express (XE) et je me connecte via JDBC. Le code a un pool de connexion universel mis en œuvre (UCP).

Pour une raison quelconque, lorsque je tente d'obtenir une nouvelle connexion je reçois:

java.sql.SQLException: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource 

Je suis en mon tomcat en utilisant maven

mvn tomcat7:run 

Ai-je besoin d'ajouter une configuration supplémentaire à mon pom.xml ou à l'Oracle lui-même pour faire fonctionner UCP?

Voici le stacktrace:

Answer 1

Je résolu ce problème en procédant comme suit:

1) Dans mon tnsnames.ora i ajouté:

(SID = XE) 

à

XE = 
    (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = Lenovo-PC)(PORT = 1521)) 
    (CONNECT_DATA = 
     (SERVER = DEDICATED) 
     (SERVICE_NAME = XE) 
     (SID = XE) 
    ) 
) 

2) Dans la liste ener.ora i ajouté:

(SID_DESC = 
     (SID_NAME = XE) 
     (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server) 
    ) 

à:

SID_LIST_LISTENER = 
    (SID_LIST = 
    (SID_DESC = 
     (SID_NAME = PLSExtProc) 
     (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server) 
     (PROGRAM = extproc) 
    ) 
    (SID_DESC = 
     (SID_NAME = CLRExtProc) 
     (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server) 
     (PROGRAM = extproc) 
    ) 
    (SID_DESC = 
     (SID_NAME = XE) 
     (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server) 
    ) 
) 

3) Restarted OracleServiceXE et OracleXETNSListener et cela a fonctionné

également après avoir vérifié la stacktrace j'ai vu cette question a été posée à plusieurs reprises, mais il a beaucoup de réponses différentes donc ce serait mon grain de sable :)
