Hadoop权威指南（第四版）,是一部相当不错的学习和指导的书。 它能帮你人门和提高。

SAN主要是高速信息存储，NAS偏重文件共享。 SAN是只能独享的数据存储池，NAS是共享与独享兼顾的数据存储池。

There is good chance you've heard that developing database-centric business applications for the J2EE platform is a complex endeavor. Luckily, there is hope. Over the past few years, analysts like Gartner Group coined the term "J2EZ" for a class of tools and frameworks that make J2EE application development easy. These so-called "J2EZ" tools target developers for whom time to market, low implementation costs, and productivity are driving factors, by providing a visual, declarative, and highly productive environment. This document provides step-by-step instructions to evaluate what you can achieve today using production versions of Oracle's offerings in this "J2EZ" space by combining the 10.1.3 versions of Oracle's JDeveloper 10g IDE, the Oracle Application Development Framework (ADF), and the Oracle JHeadstart 10g Application Generator for Oracle ADF.

To get the most out of JHeadstart, it really helps to understand more about the underlying technologies. If you have used Oracle Designer in the past to generate Oracle Forms aplications you probably agree that good knowledge of Oracle Forms is rather helpful in generating more complex functionality. This also applies to JHeadstart, understanding how technologies like ADF Data Binding, ADF Faces and JSF work, is indispensable for generating complex applications that involve customizations to the default generator templates used by JHeadstart. This section provides the pointers to obtain this knowledge.

describes the architecture and key functionality of the Oracle Application Development Framework and highlights the typical development process for using JDeveloper 10g Release 3 (10.1.3) to build web applications using Oracle ADF, Enterprise JavaBeans, Oracle TopLink, and JSF.

This manual is intended for experienced Java developers, deployers, and application managers who want to understand the security features of OC4J. It discusses the Oracle Application Server Java Authentication and Authorization Service (JAAS) Provider in detail, as well as discussing security implications of individual J2EE features, including Web applications, Enterprise JavaBeans (EJBs), the J2EE Connector Architecture, Secure Sockets Layer, and the Common Secure Interoperability Version 2 protocol (CSIv2).

最近，许多人对我们所说的“轻量级容器”表现出兴趣。我们认为这是一个趋势。轻量级容器对于web 应用的意义尤为明显；但对于其他类型的应用（包括在J2EE环境中运行的应用和独立的应用）来说，轻量级容器也有助于提高它们的复用程度，例如业务对象和数据访问对象（DAO）的复用。 什么是轻量级容器? EJB可能是最好的反例: 1. 侵略性的API(你的代码依赖于EJB) 2. 对容器的依赖(你的代码不能在EJB容器之外工作) 3. 只提供固定的一组功能,不具备配置能力 4. 5. 启动时间长 6. 部署过程取决于特定的产品，无法通用 轻量级容器的目标是避免上面所有这些麻烦事情

Running Apache as a Service You can install Apache as a Windows NT service as follows from the command prompt at the Apache bin subdirectory: httpd.exe -k install -----建立window服务 service will be called Apache2.2 and the configuration will be assumed to be conf\httpd.conf. httpd.exe -k uninstall ------移除Apache service You can control an Apache service by its command line switches, too. To start an installed Apache service you'll use this: httpd.exe -k start -----start an Apache service httpd.exe -k stop --- To stop an Apache service or httpd.exe -k shutdown httpd.exe -k restart -----强行重启
