In This Session
We will dive into the nuts and bolts of Basis Administration and
•
provide tips for administrators to ensure your SAP landscape
runs smoothly and efficiently
For those new to Basis Administration, this session will provide
•
the groundwork you need to succeed, and more experienced
administrators will find it a useful refresher
Come away with a clear understanding of SAP basic architecture,
•
interfaces, monitoring techniques, and much more!
1
What We’ll Cover
Intro the standard architecture for small, medium, and large SAP
•
landscapes
Overview of server equipment/infrastructure needed
•
Monitoring Fundamentals
•
System Performance Metrics and Customized Operations
•
Reporting
Tip to current system performance and maintenance best
•
practices for life of SAP application
SAP Fundamentals: pinpoint performance measurements from
•
hardware, database, and application layers
Database Optimization – archiving, DB compression
•
Monitoring and Business Expectations (IT role in Basis)
•
Wrap-up
•
2
SAP Architecture – Small
The most simple SAP architecture took the following forms:
•
3
Typical Very Small SAP Landscapes
One-time, “big bang” implementations
•
No ongoing rollouts
•
Less than 100 users, less than $100M enterprise
•
Appropriate for small SAP Business All-in-One implementations
•
QAS server often added later
•
4
Typical Small SAP Landscape
5
Typical Small SAP Landscape (cont.)
Three-system landscape (per major SAP application) most
•
common in SAP implementations
Changes tested and promoted from DEV  QAS  PRD
•
Servers running SAP database and application processes connect
•
through Local Area Network (LAN) or Wide Area Network (WAN) to
end users
Usually SAP application processes and database processes run
•
on the same server – 2-tier architecture
6
SAP Architecture – Medium
Typically referred to as Distributed environments, load balancing
•
becomes possible in this scenario
7
Typical Medium SAP Landscape
8
Features of a Medium SAP Landscape
More and more SAP implementations involve multiple major SAP
•
applications
With larger total data storage requirements, Storage Area Network (SAN)
•
technology starts to make sense
An SAP Solution Manager system is required by SAP
•
A pre-DEV system, typically called “sandbox” (SID=SBX) becomes
•
necessary
System to prototype new SAP functionality without impacting SAP

production or the support of production
System to test new infrastructure operations

E.g., test a new tape backup device

A 3-tier architecture with multiple application servers becomes
•
necessary with higher concurrent SAP user counts
Application servers give most flexibility/control for administrators
