  21. 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© 2012 SAP AG.

  22. 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© 2012 SAP AG.
