Administration of Application Server ABAP

Overview

The documentation for the administration of the Application Server ABAP is structured as follows:

AS ABAP concepts and functions that are relevant for the administrator
Administration tools in AS ABAP, divided into:
- Monitoring tools for AS ABAP
- Configuration and administration tools for setting up AS ABAP and for administration when system is running
- Troubleshooting: tools and functions to identify and fix errors when system is running
Note
Since the division between monitoring, configuration/administration, and troubleshooting is not clearcut and the same tools are used for different tasks, the division is only intended as a general focus for the functions.

Concepts and Features

Administrators can use the following concepts and functions of Application Server ABAP as a basis for the monitoring and administration of AS ABAP.

Function	Description
SAP Lock Concept	This section contains information about 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 in the database simultaneously.
Update Task in SAP System	This section contains information about the SAP update system, which is used for reducing the workload of SAP transactions with time-consuming database changes. The update system also avoids rollback problems that occur as a result of the differences between the logical units of work (LUW) in an SAP transaction and in the database.
SAP Number Range Buffer	The number range buffer is used to increase performance when assigning numbers. Instead of fetching the numbers each time from the database, a single access to the buffer suffices.
SAP Memory Management	This section introduces you to the SAP Memory Management System and explains which parameters are available and what the optimal settings for your system are.
SAP Printing Guide	The SAP Printing Guide describes the functions of the SAP spool system. The spool system is responsible for printing forms and documents. The data to be printed is first temporarily stored ("spooled"), then formatted, and finally transferred to a host spool system to be output.
Background Processing	This component enables background jobs to be processed with the Computing Center Management System (CCMS).
Change and Transport System	The Change and Transport System (CTS) is a tool that helps you to organize development projects in the ABAP Workbench and in Customizing, and then transport the changes between the SAP systems in your system landscape.

Tools for Monitoring, Administration and Configuration
