通过Ant-Script启动OpenJPA-Junit-Test时，打开套接字时出现UnsatisfiedLinkError / Error错误

标签： db2 openjpa

您好OpenJpa＆amp; DB2专家，

我收到了以下错误消息（下面的stacktrace）。出现错误 受影响的Junit测试是从ant脚本开始的。启动Junit-Test 在Eclipse中手动运行没有任何问题。因此似乎有例外 很奇怪对于任何可以将分析推向正确方向的输入，我将不胜感激。

答案 0 :(得分：1)

在通过OpenJPA测试连接之前，您应该检查从客户端到服务器没有连接问题。

首先，您应该检查数据库名称。您编写了“MyDBInstance”，它有8个以上的字符，DB2数据库的最大值为8.我希望这不是问题所在。

我可以看到驱动程序拒绝连接：

Caused by: com.ibm.db2.jcc.am.DisconnectNonTransientConnectionException: 
[jcc][t4][2043][11550][3.64.82] Exception java.lang.reflect.InvocationTargetException:
Error opening socket to server xyz.com/11.11.111.11 on port 62,000 with message: null.
ERRORCODE=-4499, SQLSTATE=08001

从Java中，连接问题检测不是很清楚。此错误消息没有任何说明。您应该检查是否存在防火墙问题。例如，通过以下方式测试端口：

telnet xyz.com 62000

或

telnet 11.11.111.11 62000

一旦您可以验证端口是否已打开，您可以直接使用DB2驱动程序检查与Java驱动程序的数据库连接

${DB2_DIR}/java/jdk64/bin/java -cp ${DB2_DIR}/java/db2jcc4.jar:${DB2_DIR}/java/db2jcc_license_cu.jar com.ibm.db2.jcc.DB2Jcc -url jdbc:db2://xyz.com:62000/MyDBInst -user myuser -password mypass
