Question

我正在使用db2jcc4.jar版本4.19.26和JDBC4。

当我在连接网址中添加 autoReconnect = true 时，

 <datasource jta="true" jndi-name="java:/jdbc/Name" pool-name="Name" enabled="true" use-ccm="false">
       <connection-url>jdbc:db2://host:port/db?autoReconnect=true</connection-url>
       <driver-class>com.ibm.db2.jcc.DB2Driver</driver-class>
      <driver>db2jcc4.jar</driver> ....

我收到以下错误：

IBM documentation表明此问题的解决方案是使用不同版本的JCC jar，希望这对您有用。您至少可以在问题中添加您正在使用的DB版本。如果适用于您的情况，请检查此解决方案！

本文档中建议的解决方案是：

使用JCC驱动程序版本 4.11.77 及更高版本，或升级到 DB2 V9.5 FP7 或 DB2 V9.7 FP3a 及更高版本。
