There’s been a “tradition” of a sort to deliver new features at General Availability (GA) of a new release and Service Packs 2 and 4 but focus on just maintenance updates for Service Packs 1 and 3. However, it seems that the SUSE engineers just can’t stop coming up with creative new capabilities for SUSE Linux Enterprise Server for SAP Applications – even between service packs. If you type “DNA” into the Google search engine, you get a non-scientific definition that reads “the fundamental and distinctive characteristics or qualities of someone or something, especially when regarded as unchangeable.” I would say that, after about 20 years of collaboration with SAP, innovation for SAP environments is in our DNA.
SUSE Linux Enterprise Server for SAP Applications continues to be the leading Linux platform for SAP systems. It has built-in features that reduce downtime, sustain SAP application performance and speeds up SAP system deployments. As we approach the first anniversary of our release of SUSE Linux Enterprise Server for SAP Applications 15, I’ll recap some of the features we delivered specifically for SAP systems:
Reducing downtime of critical operations
- Non-Volatile Dual In-line Memory Module (NV-DIMM) support for SAP HANA databases to reduce downtime after system reboots.
- Support for up to 512 TB virtual address space enables support for SAP HANA databases that are greater than 32 TB on IBM Power Systems. Larger databases reduce the frequency of re-starts due to memory fragmentation.
- Operations Pre/Post-scripts gives system administrators the flexibility to adapt SAP HANA system failover and recovery to their own HA scenarios and tools.
- New SAP HANA System Replication (SAPHanaSR) agent service provider calls enable faster takeovers after being notified about service changes, for example, a problem with the index server, rather than waiting for the entire landscape to report an error.
Maintaining the high performance of SAP systems
- Workload Memory Protection replaces Page Cache Management in prior releases. Based on open source cgroup, it provides a more scalable solution to protect the memory where SAP applications store data for fast access from Linux kernel memory management or any memory pressure.
Reducing the time and effort to deploy SAP landscapes
- Immediately start SAP configuration (sapconf) package changes rather than rebooting after each manual update saves time during system set-up.
In Service Pack 1, we are also including the following updates:
- Automated clustered SAP HANA upgrade package reduces complexity and potential errors with a wizard that automates separating the cluster, updating the software and then reconnecting the cluster. We introduced this feature for SLES for SAP Applications 15 after GA through the update channel.
- Workload Memory Protection updates improve automatic SAP application detection to ensure that transactional and analytical data is readily available for business users to make real-time decisions. Unlike the previous Page Cache Management feature, Workload Memory Protection can be used with SAP HANA.
- saptune automated configuration updates include the latest SAP Notes settings, improving system deployment and management.
