About this book The Administration Guide in its three volumes provides information necessary (RDBMS) Products, and includes Information about database design(found in Administration Guide: Planning) Information about implementing and managing databases(found in Administration Guide: Implementation Information about configuring and tuning your database environment to improve performance(found in Administration Guide: Performance) Many of the tasks described in this book can be performed using different interfaces: The Command Line Processor, which allows you to access and manipul databases from a graphical interface. From this interface, you can also execute SQL statements and DB2 utility functions. Most examples in this book illustrate the use of this interface. For more information about using the command line processor, see the Command reference. The application programming interface, which allows you to execute DB2 utility functions within an application program. For more information about using the application programming interface, see the Administrative API Refe The Control Center, which allows you to use a graphical user interface to perform administrative tasks such as configuring the system, managing directories, backing up and recovering the system, scheduling jobs, and managing media. The Control Center also contains Replication Administration, which allows you set up the replication of data between systems. Further, the Control Center allows you to execute DB2 utility functions through a graphical user interface. There are different methods to invoke the Control Center depending on your platform. For example,use the db2cc command on a command line, select the Control Center icon from the DB2 folder, or use the Start menu on Windows platforms. For introductory help, select Getting started from the Help pull-down of the Control Center window. The Visual Explain and Performance Monitor tools are invoked from the Control Center There are other tools that you can use to perform administration tasks. they The Script Center to store small applications called scripts.
