In a typical enterprise environment (see figure 8.1 for a simple example), one of the first things that comes to mind is the number of production server instances requiring support. A large number of servers are usually accompanied by a mix of product versions, and possibly even other DBMS products such as Oracle or MySQL. In such environments, some degree of specialization usually exists, and DBAs are often grouped into areas of product expertise. In addition to the production server instances, test and development servers, some or all of which may be provided using virtualization products, exist for the purposes of developing and testing new databases or making changes to existing production systems. Accompanying such systems are various development tools and change management processes to ensure changes are version controlled and implemented in accordance with an appropriate deployment process. In environments with critical systems, dedicated operations staff are usually on hand 24/7, with DBAs typically on call on a rotation basis. Products such as Systems Center Operations Manager (SCOM) are typically used for monitoring disk space and event logs in an attempt to identify and solve problems before they manifest themselves as production outages. In complex environments such as these, successful database administration must overcome a range of challenges, some of which are presented next.

Note: The DataFormats class encapsulates various data formats that can be used by drag and drop operations. The FileDrop format used here requires a string array as the data type. This permits multiple files to be provided at once.

Just touch the movie you wish to watch and it will begin to play (see Figure 9 1). Most videos take advantage of the relatively large screen real estate of the iPad and they play in widescreen or landscape mode. Just turn your iPad to watch.

Thread management and control is centered on the NSThread Objective-C class, and closely resembles Java s java.lang.Thread class. The equivalent methods are listed in Table 15-1. Table 15-1. Equivalent Thread Methods

The error text is there as it would have been displayed on the console, but we ve lost all of the elements of the object that haven t been displayed. And this lost information may be critical to diagnosing the problem. We need a better way to capture this information. The first mechanism we ll look at is capturing the error record by using the stream merge operator 2>&1, and then assigning the result to a variable.

class MyClass { public MyClass(int i) { this.i = i; } [Conditional("DEBUG")] public void VerifyState() { Debug.Assert(i == 0, "Bad State"); } int i = 0; } class Test { public static void Main() { Debug.Listeners.Clear(); Debug.Listeners.Add(new TextWriterTraceListener(Console.Out)); MyClass c = new MyClass(1); c.VerifyState(); } } By default, asserts and other debug output are sent to all the listeners in the Debug.Listeners collection. Since the default behavior is to open a dialog box, the code in Main() clears the Listeners collection and then adds a new listener that s hooked up to Console.Out. This results in the output going to the console. Asserts are hugely useful in complex projects to ensure that expected conditions are true.
