Oracle Expressデータベース（UCP（Universal Connection Pool）を使用したJDBC経由）

Question

Oracle Express（XE）を使用してJDBC経由で接続しています。このコードには、Universal Connection Pool Implemented（UCP）が実装されています。私は新しい接続を取得しようとすると、何らかの理由で

、私が手に：私はMavenの

mvn tomcat7:run 

を使用して、私のTomcatサーバーを実行しているよ

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

私が余分な設定を追加する必要がありますか私のpom.xmlやOracle自体にUCPを動作させるには？ここで

がスタックトレースです：

Answer 1

私は、次の手順を実行して、この問題を修正：

1）私のtnsnames.oraの私が追加：

(SID = XE) 

を

へ

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

2）リスト内私はこの質問には、それを何回か頼まれたが、見た

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）が再起動OracleServiceXEとOracleXETNSListener、それはスタックトレースを確認した後に

また

を働いた：

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

に：ener.ora私が追加しました多くの異なる答えがあるので、これは私の砂の砂であろう:)
