java - 用于在 Websphere 中创建 Oracle 数据源的 Jython 脚本

Question

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。但是当我重新启动服务器并使用控制台中的测试连接时，它就可以工作了。

如何避免服务器重新启动并使测试连接在脚本中正常工作。 在执行脚本后和重新启动之前，我确实遇到了此错误:

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:

在服务器回收之前，j2c 身份验证不会初始化。
