Welcome learners to SAP basis administration basics, featuring theory, practicals, and whiteboard explanations. Ravi Chandra shares 14 years of SAP Hana experience across end to end implementations to simplify concepts.
Explore SAP, a German enterprise software leader, and its ERP suite built on S/4HANA with HANA database for real-time analytics, artificial intelligence, and the Internet of Things.
Explore three-tier architecture in SAP with presentation, application, and database layers, highlighting decoupling, scalability, and reduced single points of failure, and compare with one-tier and two-tier models.
Explain why every SAP system in a landscape must have a unique sid, a three-alphanumeric name that enables unique identification and inter-system communication.
Understand SAP instances as units running dispatcher, work processes, and communication services on a server. Identify central, dialog, and database types, with primary instance hosting message server and MQ server.
Explore the SAP three-tier architecture, detailing the presentation, application, and database layers; compare ABAP-based and Java-based NetWeaver, and define the ABAP central services, primary application server, and additional application server.
Explain how SAP NetWeaver ASCS central services uses a message server to load balance requests from the presentation layer. Explain how the NQ server enforces locking via the enqueue table.
Examine paas and aas components in sap abap, including gateway, icm, abap dispatcher, dialogue, and the role of background, update, spool, and other work processes in the application server.
Understand the AAS work processes and PAS components, including login options, message server load balancing, dispatcher, and ICM gateway, dialogue, background, update, spool, and gateway work processes.
Configure SAP GUI to connect to an SAP system by setting the server address, SAP SID, and instance IDs for PES, ACS, and AAS.
Learn essential Linux commands for SAP administration, including cd, pwd, mkdir, ls, vi or cat, chmod, df -h, and cp -r and mv for copying, moving, and recursive directory operations.
Use SM 51 to view the AAS and PaaS instance overview, showing ten dialogue work processes, one occupied, and update, spool, and background processes; double-click to see per-instance details.
Learn to manage SAP control for starting, stopping, and monitoring SAP systems by specifying instance numbers and functions, including start system, start instance, stop system, and listing processes.
Master the start stop sequence for sap basis: boot the database, cs, pas, then application servers; stop in reverse: additional servers, pas, application server, cs, and database.
Verify status with SAP control for ACS 04, PAS 05, and AAS 06, observe the message server and dispatcher, then stop AOS 06, PAS 05, and ACS 04 in order.
Learn to stop and start an SAP HANA system by switching to Sid adm, using HDB stop/start or SAP control, and starting database before ACS, PS, and AAS.
For SAP administrators, an SAP system is the core framework that provides the technological and operational backbone for managing business processes and enterprise applications. It includes all components necessary for running SAP applications, from the underlying hardware and operating systems to the application and database layers.
Embark on your journey into the world of SAP, the leading enterprise resource planning (ERP) solution used by organizations worldwide to streamline their business processes. This introductory course focuses on SAP Basis Administration, the foundation of SAP system management, and explores the critical components that keep SAP systems running efficiently.
This course provides a practical introduction to:
• The role and types of SAP work processes (dialog, background, enqueue, and more).
• How SAP manages task distribution and user requests.
• ABAP application architecture fundamentals, including the flow of requests from SAP GUI to the database.
• Key insights into how these elements ensure system efficiency and reliability.
We will Also Understand SAP instance which is a key component of the SAP system architecture, representing a group of processes running on a server. These instances form the backbone of the SAP system, allowing administrators to manage, distribute, and optimize workloads. Each instance is self-contained and provides specific services, such as handling user requests, managing database operations, or executing background jobs.
Perfect for beginners, this course is your first step toward mastering SAP Basis concepts. No prior SAP knowledge is required!
