这不是一个答案，而是一个处理Db2异常的建议，以便有能力处理这样的错误。
如果您无法重写错误处理，唯一可以做的就是在客户端上启用JDBC跟踪或/和将Db2 dbm cfg DIAGLEVEL参数设置为4。

PreparedStatement pst = null;
try 
{
    pst = ...;
    ...
    int [] updateCounts = pst.executeBatch();
    System.out.println("Batch results:");
    for (int i = 0; i < updateCounts.length; i++) 
      System.out.println("  Statement " + i + ":" + updateCounts[i]);
} catch (SQLException ex) 
{
    while (ex != null) 
    {
      if (ex instanceof com.ibm.db2.jcc.DB2Diagnosable) 
      {
        com.ibm.db2.jcc.DB2Diagnosable db2ex = com.ibm.db2.jcc.DB2Diagnosable) ex;
        com.ibm.db2.jcc.DB2Sqlca sqlca = db2ex.getSqlca();
        if (sqlca != null) 
        {
          System.out.println("SQLCODE: " + sqlca.getSqlCode());
          System.out.println("MESSAGE: " + sqlca.getMessage());
        } 
        else 
        {
          System.out.println("Error code: " + ex.getErrorCode());
          System.out.println("Error msg : " + ex.getMessage());
        }
      } 
      else 
      {
        System.out.println("Error code (no db2): " + ex.getErrorCode());
        System.out.println("Error msg  (no db2): " + ex.getMessage());
      }
      if (ex instanceof BatchUpdateException) 
      {
        System.out.println("Contents of BatchUpdateException:");
        System.out.println(" Update counts: ");
        System.out.println(" Statement.SUCCESS_NO_INFO: " + Statement.SUCCESS_NO_INFO);
        System.out.println(" Statement.EXECUTE_FAILED : " + Statement.EXECUTE_FAILED); 

        BatchUpdateException buex = (BatchUpdateException) ex;
        int [] updateCounts = buex.getUpdateCounts(); 
        for (int i = 0; i < updateCounts.length; i++) 
          System.out.println("  Statement " + i + ":" + updateCounts[i]);
      }
      ex = ex.getNextException();
    }
