Oracle Express-Datenbank über JDBC mithilfe eines UCP (Universal Connection Pool)

Question

Ich verwende Oracle Express (XE) und verbinde mich über JDBC mit ihm. Der Code verfügt über einen Universal Connection Pool (UCP).

Aus irgendeinem Grund, wenn ich versuche, eine neue Verbindung zu bekommen, erhalte ich:

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

ich mein Tomcatbediener läuft Maven mit

mvn tomcat7:run 

Muss ich extra Konfiguration hinzufügen müssen an meine pom.xml oder an das Oracle selbst, damit UCP funktioniert? Hier

ist die Stacktrace:

Answer 1

ich dieses Problem behoben, indem Sie die folgenden Schritte ausführen:

1) In meinem tnsnames.ora i hinzugefügt:

(SID = XE) 

zu

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

2) In Liste ener.ora i hinzugefügt:

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

zu:

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) erneut gestartet OracleServiceXE und OracleXETNSListener und es funktionierte

Auch nach dem Stacktrace Überprüfung ich sah, war diese Frage mehrmals gefragt, aber es hat viele verschiedene Antworten, so würde dies mein Sandkorn sein :)
