Optimizing the performance of database servers and databases

Memory: Pages/sec counter is used to detect whether or not the memory bottleneck is caused by I/O overhead.
Disk I/O bottleneck can be monitored by Physical Disk: % Disk Time and Physical Disk: Avg Disk Queue Length counters.
The System Monitor tool is used to know the cause of slow authentication.
The SQLServer: Buffer Manager performance object is used to check the amount of RAM used by a computer.
The Physical Disk: %Disk Time counter measures the pressure on a physical hard disk array.
Add more RAM if the reading of Memory: Pages/sec counter is high.
Reduce the Maximum Worker Thread configuration settings if the value of System: Processor Queue Length counter is high.

Developing applications that use system types and collections

Use the CausesValidation property of the ImageButton class to set a value to indicate whether validation is performed on a Web server control when an ImageButton control is clicked.
Installation packages are created for deploying a Web application by using a Web Setup project. A merge module project is used for components to be added to the application.
Use the Web Setup project and Deployment project to create installation packages for the deployment of Web-based applications such as XML Web services, Web applications etc., to a Web server.
Use a RequiredFieldValidator control to check whether or not an input control contains a value.
Use a RegularExpressionValidator control to check whether or not the value entered into a form field matches the pattern specified by a regular expression.

The SessionID property of the HttpSessionState class identifies an active ASP.NET session by using a unique session ID.
The @ Import directive is used to explicitly import a namespace into an ASP.NET application.
The @ Implements directive is used to implement a specified .Net Framework interface in a Web page.
The CodeBehind attribute of the @ Page directive specifies the name of the compiled file that contains the class associated with the page.
The ErrorPage attribute of the @ Page directive is used to set the URL if an unhandled exception occurs. Sam can set this target to the home page.
The Language attribute of the @ Page directive specifies the language used while compiling the inline rendering and code declaration blocks.
The Inherits attribute of the @ Page directive specifies a code-behind class for the page to inherit. It can be any class that is derived from the Page class.
Public variables and objects can be accessed from all other procedures and functions in all the modules in the same project.
The public class Manager : HeadOfDept declaration will create a class named Manager, which implements the HeadOfDept interface.

Configuring Recovery Manager

The control file, target database catalog, and Recovery catalog is used to store the RMAN’s persistent settings.
The alert log file is used to find out the values of the changed parameters at the time of instance startup.
The NLS_LANG parameter must be set to specify the language, territory, and character set used in an application.
CONFIGURE RETENTION POLICY CLEAR is a command that will configure the retention policy to the default of REDUNDANCY 1.
CONFIGURE is an RMAN command that configures an RMAN environment.
The rman target/ command is used to maintain backup copies by connecting to the target database and returns the RMAN prompt to issue further backup commands.
The redo files are opened after executing the ALTER DATABASE OPEN command on a database when it is in MOUNT mode.

Planning and Design of Flash Applications

The Properties panel/Property inspector enables a user to access various attributes of whatever is currently selected on the stage or in the Timeline.
The DynamicHeapSize capability specifies the amount of dynamic memory that is allocated to Flash Lite.
The Align panel controls the space between the objects and the size of the objects in respect of each other.
The Distribute area of the Align panel spaces the objects according to a common reference point of top, middle or bottom.
Motion guide layers are special layers that enable a user to draw paths along which the objects can be animated.
