标题：impdp中的DISABLE_ARCHIVE_LOGGING参数测试

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

在oracle 12c版本中引入了impdp中的TRANSFORM中的DISABLE_ARCHIVE_LOGGING值，可以实现在导入的时候使用nologging处理从而减少日志量也增加速度,但是在force logging情况下该参数无效

这里可以看出来在force logging情况下，设置DISABLE_ARCHIVE_LOGGING参数不生效
从上述测试在不管是非归档还是归档情况下使用DISABLE_ARCHIVE_LOGGING都会减小导入时间，减少归档量，但是需要注意如果数据库是force logging情况下，DISABLE_ARCHIVE_LOGGING参数会无效。

深入探索 JUnit 4

开始之前 关于本教程 引入 Java 5 注释为 JUnit 带来了显著改变,使它从一个受广大开发人员了解和喜爱的测试框架转变成了一个更为精简但却不那么为人熟知的框架.在本教程中,我将探讨 JUnit 4 最重要的转变,并介绍一些您也许已经耳闻但还没用过的激动人心的新功能. 目标 本教程将循序渐进地向您讲述 JUnit 4 的基本概念,侧重于新的 Java 5 注释.通过这个一小时教程的学习,您将能够理解 JUnit 4 的主要改变,也将熟悉这些功能,如异常测试.参数测试以及新的灵活固件模型.您
