The SAP Lock Concept (BC-CST-EQ) TutorialThe SAP System is equipped with a special lock mechanism that synchronizes access to data on the database. The purpose of the lock mechanism is to prevent two transactions from changing the same data on the database simultaneously. Implementation Considerations Locks are defined generically as “lock objects” in the Data Dictionary. A lock request is a specific instance of a lock object and locks a certain database object, such as a correction or a table entry. Lock entries are usually set and deleted automatically when user programs access a data object and release it again.
Integration The SAP lock mechanism is closely related to the update mechanism in R/3 [Extern]. A description of handling lock objects is provided in the ABAP Dictionary Documentation under Lock Objects [Extern]. The ABAP documentation explains the key elements of the lock concept with regard to programming ABAP transactions in the section entitled The R/3 Lock Concept

Now your thoughts are turning to access control. Just enough time to splice in that trusty user authentication and roles module, make a few tweaks and move on to the next project. Wait! Do you really want to contribute yet another authorization stovepipe to the growing forest? We all curse the proliferation of authentication and authorization “solutions” on the Web. Yet we continue to treat access control as an after thought.
Developers accept the benefits of adopting third-party solutions for common functions such as data storage, cryptography, numerical analysis, parsing, etc., yet continue to roll their own application access control solutions. Why? The disadvantages of RYO are obvious: application-specific user accounts and passwords proliferate, each application reinvents how roles should be implemented -- perhaps even a language for specifying access constraints -- and, if integration with an external authentication framework is required, each application must implement interfaces to the drivers. This is irritating to our users, a headache for those who administer the applications, and costly to maintain.
In this article we develop a set of Web 2.0 best practices for “outsourcing” the access control problem. Following these practices produces applications that readily integrate into an organization’s existing access control infrastructure, and simplifies application development and maintenance.

PDT supports two debugging tools: XDebug and the Zend Debugger. Learn how to configure PDT for debugging PHP scripts and discover which perspectives you use when taking closer looks at your scripts.
This tutorial demonstrates how to configure the PHP Development Tools (PDT) plug-in for Eclipse to debug your PHP scripts. It also introduces the perspectives you'll use (namely, PHP Debug) when taking closer looks at your PHP scripts.
Objectives
After completing this tutorial, you'll be able to set up either XDebug — an open source project that allows you to debug executable scripts and scripts running on a Web server — or the Zend Debugger in Eclipse using the PDT project to develop PHP applications. You'll understand the various parts of the PDT project's PHP Debug perspective and learn how to set up, view, and work with breakpoints. You also learn how to inspect the values of variables as you are stepping through the code, as well as how to debug PHP Web applications on your local server so you can run through your PHP Web application with the debugger.
Prerequisites
To get the most out of this tutorial, you should have done a bit of PHP development. But what matters more is that you've done software development in general. You'll understand the debugging concepts better if you're familiar with debugging any other language.

But before launching into the vast possibilities, let’s start with the basic foundation. The good news is that ActionScript commands follow a well- defined pattern, sharing similar syntax, structure, and concepts. Mastering the fun-damental grammar puts you well on the way to mastering ActionScript. This chapter addresses the frequent tasks and problems that relate to core Action- Script knowledge.
Whether you are a beginner or master—or somewhere in between—these recipes help you handle situations that arise in every ActionScript project. This book assumes that you have obtained a copy of Flex Builder 2 and have success-fully installed it on your computer. It’s also helpful if you have some experience using a previous version of ActionScript as well. When you launch Flex Builder 2, the Eclipse IDE should start up and present you

It supports RFC1483 Multiprotocol over AAL5. You can use the CellPipe 20A to create a dedicated, physical connection to Digital Subscriber Line (DSL) equipment at the telephone company. You first attach your computer or Ethernet hub to the CellPipe 20A. Then, you connect the unit to a standard telephone line. The other end of the line connects to DSL equipment at the telephone company. Your DSL circuit is dedicated to your CellPipe unit.
With DSL, you have the capacity to transfer data at very high rates. The actual rate can vary according to the type of CellPipe you use, the distance between the CellPipe and the DSL equipment, and the line quality of the connection. You can use DSL technology for Internet access, telecommuting, remote office connectivity, multimedia, and videoconferencing.
CellPipe 20A features
The CellPipe 20A includes the following features:
• ATM over ADSL through a single copper twisted-pair telephone line
• 10/100 MB Ethernet (Auto-detect)
• High-speed bridging
• DMT-based standards
• Support for ATM AAL5 (ATM Adaptation Layer Type 5)
• Support for VC-based multiplexing and LLC encapsulation of RFC1483
• Autonegotiating rate adaptation
• Ease of use
• Easy configuration
CellPipe 20A management
The CellPipe 20A is managed through a command-line interface. You set up a serial connection and use VT100 emulation software to display configuration information on your computer monitor and use the computer to enter any changes. You can use the command-line interface to change the VPI and VCI value, and theGradekeeper User's GuideGradekeeper is a powerful tool for managing your gradebook. With Gradekeeper you can:
