Java 用于在Websphere中创建oracle数据源的Jython脚本

下面的代码成功创建了数据源，但调用测试连接时出现异常。但当我重新启动服务器并在控制台中使用测试连接时，它就可以工作了

如何避免服务器重启并使测试连接在脚本中工作。 在执行脚本之后和重新启动之前，我确实存在以下错误：

J2CA0130I: Data Source [nMINEDB] has Component-managed Authentication Alias [test/nMINEDBUser] but no corresponding J2C Authentication Data Entry is defined in security.xml. This may have undesirable effects.

代码：

直到服务器被回收，j2c身份验证才被初始化。

我通常对脚本使用wsadmin，因为我不熟悉jython脚本是如何完成的。然而，我已经看到，当您创建新的j2c身份验证并将其与新的数据源一起使用时，需要回收jvm或节点同步。我已经对此进行了多次测试，除非完成循环/节点同步，否则数据源将抛出j2c身份验证错误。因此，唯一的方法是像我在代码中所做的那样重新启动服务器，这也是一个bug@Websphere。
