This line outputs the string A simple C# program. followed by a new line on the screen. Output is actually accomplished by the built-in method WriteLine( ). In this case, WriteLine( ) displays the string that is passed to it. Information that is passed to a method is called an argument. In addition to strings, WriteLine( ) can be used to display other types of information. The line begins with Console, which is the name of a predefined class that supports console I/O. By connecting Console with WriteLine( ), you are telling the compiler that WriteLine( ) is a member of the Console class. The fact that C# uses an object to define console output is further evidence of its object-oriented nature. Notice that the WriteLine( ) statement ends with a semicolon, as does the using System statement earlier in the program. In general, statements in C# end with a semicolon. The exception to this rule are blocks, which begin with a { and end with a }. This is why those lines in the program don t end with a semicolon. Blocks provide a mechanism for grouping statements and are discussed later in this chapter. The first } in the program ends Main( ), and the last } ends the Example class definition. One last point: C# is case-sensitive. Forgetting this can cause serious problems. For example, if you accidentally type main instead of Main, or writeline instead of WriteLine, the preceding program will be incorrect. Furthermore, although the C# compiler will compile classes that do not contain a Main( ) method, it has no way to execute them. So, had you mistyped Main, you would see an error message that states that Example.exe does not have an entry point defined.

p = false; q = true; Console.Write(p + "\t" + q +"\t"); Console.Write((p&q) + "\t" + (p|q) + "\t"); Console.WriteLine((p^q) + "\t" + (!p)); p = false; q = false; Console.Write(p + "\t" + q +"\t"); Console.Write((p&q) + "\t" + (p|q) + "\t"); Console.WriteLine((p^q) + "\t" + (!p)); } } 5. Compile and run the program. The following table is displayed: P true true false false Q true false true false AND true false false false OR true true true false XOR false true true false NOT false false true true

In this section, the developments of each of the attributes are presented. It is impractical to discuss these in any detail here, as several standards are involved, but they are highlighted with the progress to date. Some selective developments are, however, elaborated in reasonable depth given their importance in the enabling of Carrier Ethernet. The MEF s prominent role in enabling Carrier Ethernet is shown in Figure 2.17, which highlights the specifications and specific attributes being addressed in the areas of Architecture, Management, Services, and Testing Measurement.

Network firewalls are the primary line of defense against external security threats; however, a firewall is not a panacea of network security. A firewall is a system or group of systems that enforce a boundary between two or more networks. In the classic implementation, shown in Figure 6-5, the firewall system is composed of a packet-filtering perimeter router, an isolation LAN (screened subnet) with a dual-homed bastion host, and an interior packet-filtering router.

The prototype for tmpnam( ) is found in <stdio.h>. The tmpnam( ) function is defined by the ANSI/ISO C/C++ standard. It generates a unique filename and stores it in the array pointed to by name. The main purpose of tmpnam( ) is to generate a temporary filename that is different from any other filename in the directory. The function may be called up to TMP_MAX times, defined in <stdio.h>. Each time it generates a new temporary filename. A pointer to name is returned. If name is null, a pointer to an internal string is returned.

As a designer, you can build a simple query within Designer to preview the SQL generated. However, to diagnose performance issues, you most often will want to see the SQL from a query a user has built. To access the SQL from within Desktop Intelligence: 1. Select Data | Edit Data Provider and click SQL to launch the SQL viewer. 2. From within the SQL viewer, click Save to save the SQL to a separate text file. From within the Web Intelligence, Java Report panel: 1. Select Edit Query from the menu bar.

EdgeSight for XenApp has a unique architecture in that it uses a multitier database design. Each EdgeSight for XenApp server agent maintains its own local database on the XenApp server. The agent databases utilize what Citrix calls the 15/5/60 model for data sampling intervals. This model refers to a 15-second sampling level for the most recent four hours. After this time the agent aggregates the level up to five-minute sampling levels, and finally prior to uploading the agent database to the EdgeSight database server the agent further aggregates the level into one-hour samplings. The agents by default are scheduled to upload their individual data to the EdgeSight database server twice a day, at the default times 05:00 and 19:00. The power of this distributed database model is that the performance impact on the network is very low and predictable. The other benefit in the design is the dual use of the EdgeSight Console to allow Citrix administrators to access real-time user, process, and device data directly from the agent databases as well as detailed historical data from the EdgeSight Server database. Figure 12-1 illustrates the components that make up an EdgeSight for XenApp environment. We will discuss each of these in detail.
