SAP on Linux support
Common support message handling via SAP ticket system Operating support related messages are processed on component
BC-OP-LNX On development level LinuxLab members will take over
Direct access to distribution- or technology partner specific know-how Integrated partner’s employees Further analysis and processing inside the SAP ticket system If necessary, hand-over of the support message to the partner’s
support system Parallel customer ticket in the partner’s support system Direct forwarding via an integrated support infrastructure, e.g. via SuSE’s SAP
Solution Manager integration

Example of a LinuxLab project: Pagecache Limit
Needed to configure a system’s available amount of pagecache Known in Unix environments but not on Linux (yet) Linux allows to tune the Linux Kernel’s general pagecache strategy (vm.swappiness)
Helpful for system sizing Protect the SAP system’s memory resources
from general file system I/O caching

Know How and Best Practices - WorkshopThe Experts
Beside vendors such as HP, VMware, SAP and SUSE several partners have implemented successful SAP HA projects with SUSE Linux Enterprise High Availability Extension:
• B1 Systemshttp://www.b1-systems.de/
• Computer Conceptshttp://cc-dresden.de
• LINBIThttp://www.linbit.com/
• Realtechhttp://www.realtech.de/
The Workshop
In a joint HA workshop users and partners developed, tested and documented together with HP, SAP and SUSE best practices for SAP high availability implementations:
Whitepaper: SAP solutions made High Available on SUSE Linux Enterprise Server for SAP Applications.
Best Practice Guide: Best Practices for Running SAP NetWeaver on SUSE Linux Enterprise High Availability Extension.

SAP NetWeaver High Availability Cluster 730 Certification
Details of the certification:
• certifies the Start/Stop infrastructure within HA-Setups (SAP NetWeaver Management Agents, Cluster-API).
• establish a single SAP HA setup scenario that will be known to all HA Vendors and will be the reference.
• unify HA setups for SAP NetWeaver 7.x, based on 7.20 DCK availability for ABAP as well as for Java Application Servers
