Oracle JDBC连接与Weblogic 10数据源映射，给出问题java.sql.SQLException：Closed Connection

我正在使用weblogic 10 JNDI数据源来创建JDBC连接，下面是我的配置

<?xml version="1.0" encoding="UTF-8"?>
<jdbc-data-source xmlns="http://www.bea.com/ns/weblogic/90" xmlns:sec="http://www.bea.com/ns/weblogic/90/security" xmlns:wls="http://www.bea.com/ns/weblogic/90/security/wls" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/920 http://www.bea.com/ns/weblogic/920.xsd">
  <name>XL-Reference-DS</name>
  <jdbc-driver-params>
    <url>jdbc:oracle:oci:@abc.XL.COM</url>
    <driver-name>oracle.jdbc.driver.OracleDriver</driver-name>
    <properties>
      <property>
        <name>user</name>
        <value>DEV_260908</value>
      </property>
      <property>
        <name>password</name>
        <value>password</value>
      </property> 
      <property>
        <name>dll</name>
        <value>ocijdbc10</value>
      </property>
      <property>
        <name>protocol</name>
        <value>oci</value>
      </property> 
      <property>
        <name>oracle.jdbc.V8Compatible</name>
        <value>true</value>
      </property>
      <property>
        <name>baseDriverClass</name>
        <value>oracle.jdbc.driver.OracleDriver</value>
      </property>
    </properties>
  </jdbc-driver-params>
  <jdbc-connection-pool-params>
    <initial-capacity>1</initial-capacity>
    <max-capacity>100</max-capacity>
    <capacity-increment>1</capacity-increment>
    <test-connections-on-reserve>true</test-connections-on-reserve>
    <test-table-name>SQL SELECT 1 FROM DUAL</test-table-name>
  </jdbc-connection-pool-params>
  <jdbc-data-source-params>
    <jndi-name>ReferenceData</jndi-name>
    <global-transactions-protocol>OnePhaseCommit</global-transactions-protocol>
  </jdbc-data-source-params>
</jdbc-data-source>

当我运行批量任务时，有大量连接被建立和关闭，有时它会为批量任务中的任何任务提供连接关闭异常。

下面是详细的例外'

java.sql.SQLException: Closed Connection
 at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:111)
 at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:145)
 at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:207)
 at oracle.jdbc.driver.OracleStatement.ensureOpen(OracleStatement.java:3512)
 at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3265)
 at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:3367)

有什么想法吗？

Answer 1

您可以将<global-transactions-protocol>参数更改为none并执行代码：

<jdbc-data-source-params>
    <jndi-name>ReferenceData</jndi-name>
    <global-transactions-protocol>none</global-transactions-protocol>
</jdbc-data-source-params>

Answer 2

问题是由于跨代码的连接共享.... 糟糕的编程.... :(纠正它.... 感谢
