SAP is now used by a large number of companies because the high performance of their business processes is insured by the solutions of this system. The SAP installation and configuration is the first step to success.
SAP installation has to be taken care of by an expert, a specialist familiar with the procedure and with administrative rights to the system. Also, technical factors like: the multi-layer architecture, the hardware sizing, scalability, lock management, buffer handling contribute a lot to the SAP installation. The expert must make use of the SAP documentation and secure the data that users have access to. The specific procedural details have to be taken into consideration when performing a SAP installation.
Having considered the SAP installation of R/3 as an example, some facts have to be underlined. The SAP application is very demanding on system resources, especially the disk storage subsystem. This is why adding a solid state disk for the frequently used files improves the performance. Because of this approach, the SAP installation is quick and easy to perform. This way, the Sap installation can be done on any computer system and without any special drivers.
In the case of the R/3, there are many things that should be taken into consideration in the analysis of the SAP installation:
-the basic components of the system
-the hardware elements that have the biggest influence on performance
-the relative loading of the different modules
The software and firmware of the SAP installation can be separated into: The Application, The Database and the Operating System. The highest gains were of 60% in the Application, where they were actually expected. The achieved benefit from using a solid state disk was obtained after several efforts of system performance improvement. The sizing of the disk and the number of frequently used files that had to be selected was first determined. Any Sap installation process has to be analyzed in order to find out if this direction is useful to achieve certain goals.
However good this specific SAP installation was, each SAP installation has to have a different, appropriate tuning technique. Many factors weight a lot in the SAP installation: the hardware, the operating system, the database, the number of active modules and clients' performance requests. A skilled staff and the advice of a specialist can help determine whether this solution is applicable in a certain case as it may not be appropriate for any SAP installation.
As SAP installation is problematic when trying to obtain a system with a high performance, a series of factors have to be analyzed to get the best results possible. With a little effort and guidance from a consultant or specialist and knowledge about SAP, solutions can be found.
