System Engineering is complementing our consulting know-how. All the technical resources underlying your SAP system are also part of our solution portfolio. Our deep knowledge in enterprise class operating system environments and database management systems gives us strong competence on different platforms for providing better services.
 

Server Setup & Configuration

No matter for which system you have decided, we support you during on of the most difficult tasks for a system administrator: the configuration phase! Here we can assist you making important design decisions such as the correct sizing of the system hardware, the layout of the network, the way in which R/3 Basis components should be set up, how such procedures as backing up should be organized, and so on:

• Support during hardware sizing and design

• Server installation and set-up, operating system and memory configuration

• Decide on the optimal configuration for the system

• Make sure that you can meet the hardware and software requirements specified by SAP

• Work out how the software components must be distributed to disks

• System software setup & configuration (utilities, licensed programs, language settings, printing, etc.)

• Cluster installation, configuration and fail-over testing

Operating System Management

Each platform requires specific preparation and configuration activities to be ready for a successful SAP installation. Here we have to follow strictly the recommendations from SAP and these recommendations have to be applied on Windows, UNIX and AS/400 systems.

Depending on the release of R/3 or the mySAP.com component you have chosen, we have to select the supported operating system and database management system release which has currently the longest maintenance lifecycle.

• Prepare local or domain installation, active directory integration and LDAP support

• Adjusting virtual memory, swap space, granting user rights, change system values, adapting kernel parameters

• TCP/IP and general network configuration

• Disk and storage pool configurations, setup file-systems and raw devices

• Install latest operating system patches and hot fixes which are released by SAP

• Configure and change system startup, create start- and stop-procedures for SAP and the DBMS

• Setup installation and transport directory

Database Installation & Upgrades

Depending on which database management system needs to be installed or upgraded, there are specific pre- or post-processing configuration activities necessary on the server (DB server) and on the client (application server) side.

Once the DBMS is installed or upgraded to a newer release, it needs to be configured by assigning storage pools and changing memory and system parameters to avoid errors situations and bottlenecks in the database.

• Prepare the operating system and file system for the DBMS installation or upgrade

• Install or upgrade database management system

• Clustering MS SQL-Server or ORACLE

• Assigning storage pools, memory and system parameters

• Installing and configuring SAP database tools (such as SAPDBA, BRBACKUP, BRARCHIVE, BRRESTORE, BRSPACE)

• Change and optimize database layout

• Implement database backup

System Migrations

If you have decided for newer hardware technologies, your current SAP applications and databases need to be migrated and adjusted to the new environment. Depending on the technology you have decided for, there may be some requirements concerning operating system and DBMS release level which needs to be previewed already on the current environment before the migration can be done.

• Prepare the current system (OS, DBMS and application) for migration

• Upgrade OS and database management system

• Install and configure target system

• Optimize file-system, database layout and resource management

• Move SAP applications to the target system

• Perform migration post-processing activities

System Programming

We can help you better and more efficient manage your systems by creating scripts and procedures for daily and monthly database- and system-backup, periodic system tasks (such as DB reorganization, ORACLE table space and index management, cleanup activities, etc.) interfaces and other operating system related tasks.

For example you may have your SAP system running on Windows 2003 on a MSCS cluster environment with ORACLE as DBMS, you may want to do fully automated offline full system backups.

• OS/400 CL programming

• UNIX shell scripting

• Windows CMD or PERL scripting

• SAP system integration

Performance Tuning & Optimizations

Are you satisfied with the performance of your SAP system? If not, the improvement can often not be found in simply changing one system parameter. It is the overall system (CPU, memory, I/O performance, system configuration and parameters, workload- and instance-distribution) that needs to be analyzed with respect to your current workload during normal operation and peek hours as well.

Our experience from more than 100 projects on different hardware, operating system and database combinations in large, midsized and small environments can help you finding a way to improve the overall performance of your system.

• SAP system analysis (installation, memory configuration, workload distribution, instance configuration)

• Analysis on operating system level (CPU, memory, swap, disk layout)

• Database performance (missing indexes, data distribution on disk, table space layout, archiving and journaling)

• Overall system analysis

• Create detailed performance reports with rating and action plan (recommendations)
