SAP Solutions on Linux - Customer Feedback

Why SAP customers choose Linux as their OS platform

SAP systems are operated in mission critical server environmentsEfficiently administer your Linux servers Take advantage of available Unix knowledge

Integration is key, and Linux is an integration platformSeamlessly integrate into your network of Unix serversUse Linux to achieve Windows - Unix integration

Linux offers the highest degree of vendor independenceHardware for Linux has a very good performance to price ratioUnix-like environment with all advantages of free vendor selection

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

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

Available since SLES 11 SP1: vm.pagecache_limit_mb Documented in SAP note 1557506:

SAP Start Service High Availability interface

sapstartsrv is now cluster-aware Partners can implement an interface

SUSE on-site LinuxLab engineershelped building up reference systems

Wrote a documentation and a reference implementation of howto 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

SLES for SAP Applications 11Page 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
