 All releases since R/3 4.0B, including SAP Business Suite 2005/8 and latest BS7i2011
 Full availability of on SAP NetWeaver 7.x, ’04, 6.x and SAP Basis 4.x based solutions
Supported Distributions
 SUSE Linux Enterprise Server
 Red Hat Enterprise Linux
 Oracle Linux for Oracle based SAP environments
Supported Databases
 Sybase ASE, MaxDB and HANA
 IBM DB2 and Oracle
Linux is reference platform for SAP software development
 Best availability of SAP solutions

19. SAP Solutions on Linux - Customer Feedback
Why SAP customers choose Linux as their OS platform
 SAP systems are operated in mission critical server environments
 Efficiently administer your Linux servers
 Take advantage of available Unix knowledge
 Integration is key, and Linux is an integration platform
 Seamlessly integrate into your network of Unix servers
 Use Linux to achieve Windows - Unix integration
 Linux offers the highest degree of vendor independence
 Hardware for Linux has a very good performance to price ratio
 Unix-like environment with all advantages of free vendor selection

20. LinuxLab: SAP Linux community
 SAP founded the LinuxLab when making SAP available on Linux
 LinuxLab is a joint development co-operation between hardware and technology
partners, distributors and SAP itself
 Since 1999, LinuxLab helps to keep Linux solutions ready for business critical
enterprise computing
 SAP LinuxLab is your personal contact inside of SAP
support delivering first class support down to development level
 Several SAP initiatives like Adaptive Computing started as projects in SAP LinuxLab
and growing ...

21. 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

22. 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 Influence of pagecache limit on throughput
from general file system I/O caching 110.00%
100.00%
Available since SLES 11 SP1:
90.00%
 vm.pagecache_limit_mb
 Documented in SAP note 1557506: 80.00%
Linux paging improvements 70.00%
3.0.34-0.7-default pagecache limit set 3.0.34-0.7-default

23. SAP Start Service High Availability interface
 sapstartsrv is now cluster-aware
 Partners can implement an interface
 SUSE on-site LinuxLab engineers
helped building up reference systems
 Wrote a documentation and a
reference implementation of how
to use the script connector
 Partner certification program available
 To certify the start/stop infrastructure within HA setups
 To clarify support responsibilities
 See http://scn.sap.com/docs/DOC-26718 for more details

Page Cache Limit
Tells kernel that once page cache is
filled to configured limit, application
memory is more important and should
not be paged out
No memory paged out if memory
footprint of the workload plus the
configured page cache limit does not
exceed the amount of physical RAM
