The new SAPHanaSR takeover blocker improves the SUSE HA integration with SAP administration solutions like SAP HANA Cockpit. This solution closes the gap between the native SAP tools and the SUSE SAPHanaSR cluster solution. One of the most critical administration mistakes is to run a manual takeover on the secondary SAP HANA instance without taking […]

In some cases the SAP HANA indexserver is crashing and it takes very long for the service to fail completely. This is the reason why SAP HANA delays to report this failure towards the HA cluster. Obviously in such cases it is extremely helpful to have an emergency braking. This blog article describes why the […]

This blog describes the optimal maintenance procedure using SAP HANA handshake takeover on SUSE clusters. Major Steps for a successful maintenance procedure For processing a maintenance for your SAP HANA database with system replication and controlled by the SUSE cluster we recommend always to follow these three major steps. Begin the maintenance: Set the multi-state […]

SAP will enable the SAP Startup Framework for systemd. In short words the updated startup framework will be available for the SAP Host Agent, the SAP NetWeaver application server platform, the SAP S/4HANA ERP platform, and potentially later for the SAP HANA database as well. Here we discuss the benefits and the consequences for the […]

End of January 2019 we have achieved a new milestone for our SLES for SAP Applications cluster solutions. We passed the SAP certification named “SAP S/4-HA-CLU 1.0” as the first cluster vendor. Now, end of November 2021, we are again the first vendor with a certification using the simple-mount cluster architecture. We have selected SLES […]

SAP HANA supports multi-target system replications. But what does that mean “multi-target”? And how use it in a SUSE cluster? This blog introduces you to SAP HANA multi-target system replication and describes the major steps to get it running with the SUSE HA cluster. In addition it provides you a first view on how it […]

Today we see increasing demand for transactional workload such as ERP based on S/4HANA using SAP HANA scale-out systems. Accordingly now also multi-target system replication comes into focus of our customers. Since 2016 SUSE offers SAPHanaSR-ScaleOut, an high availability solution for SAP HANA scale-out systems. SAP HANA scale-out systems typically covered analytical workloads only (BW […]

Today I want to blog about the feature named Simple Mount Structure for SAP Application Platform. We like to add this feature to our product in the near future. It is a kind of great simplification of the SAP HA cluster. Customers told us that the classical filesystem structure for a cluster controlling the central […]

Good news! Yesterday we published a major update of our setup guide for SAP HANA system replication on SLES for SAP 12 (SP4) for the performance optimized scenario. The updated guide describes planning, set up, and basic testing of the SUSE Linux Enterprise Server for SAP Applications based high availability solution scenario “SAP HANA Scale-Up […]

More and more customers are asking SUSE how to integrate the SAP Web Dispatcher into the SUSE’s cluster solution. This blog describes step-by-step how to integrate this important SAP software component into pacemaker. The base of the solution is SUSE Linux Enterprise Server for SAP Applications. You can use the solution for any currently supported […]

End of January we have achieved a new mile stone for our SLES for SAP Applications cluster solutions. We passed the SAP certification named “SAP S/4-HA-CLU 1.0” as the first cluster vendor. We have selected SLES for SAP Applications 15 as platform for the certification. However you could also implement the cluster with SLES for […]

Why should I change my route? Sometimes the direct way could end up in dead end. In such cases an alternative route is needed to come to the desired destination. What does that mean for my SAP HANA cost optimized scenario? Where is the possible dead end? In some installations we have seen that the […]

The problem You have setup your SAP HANA system replication cluster. The cluster is working. The tests are passed. Let’s celebrate! But how can I see in the High Availability Web Konsole (HAWK), if the SAP HANA system replication pair is currently in sync? Is there an easy method to show the current replication status […]

We did it again! SAP’s LinuxLab is an excellent place for collaboration projects. Architects from Amazon Web Services and SUSE developed a brand-new best practice available at https://www.suse.com/documentation. The new guide explains how to automate SAP HANA system replication (SR) in the AWS virtual private cloud with SUSE cluster technology. The solution is of course […]

SUSE architects have improved the cluster architecture to be fully compatible with the updated SAP certification for SAP NetWeaver cluster integration. SAP released this updated SAP certification under the name NW-HA CLU 740. SUSE passed this certification on SUSE Linux Enterprise Server for SAP Applications 12 for both Intel X64 and IBM Power little endian […]

For mission critical systems it is important to have the right direction towards zero downtime. To go towards zero downtime is not only to build just another high availability cluster running your critical resources. It is also important to align the maintenance processes. The SAP NetWeaver SUSE Cluster Integration using the sap_suse_cluster_connector exactly addresses the gap […]

This blog article is part of a blog series, explaining the SAPHanaSR Scale-Out solution. This article explains the SAPHanaSR technology and HANA System Replication at a more detailed level. Read also an overview around SAP HanaSR Scale-Out and HANA System Replication written by team colleague Markus Gürtler. SAP HANA System Replication on SLES for SAP […]

The new SAPHanaSR solution created by SUSE is to automate the takeover in SAP HANA system replication setups. The basic idea is that only synchronizing the data to the second SAP HANA instance is not enough, as this only solves the problem of having the data shipped to a second instance…

SAP customers invest in SAP HANA” is the conclusion reached by a recent market study carried out by Pierre Audoin Consultants (PAC). In Germany alone, half of companies expect SAP HANA to become the dominant database platform in the SAP environment. In many cases, the “SAP Business Suite® powered by SAP HANA” scenario is already […]

You want to have access (name resolution) for the internet and also for an internal network, but neither the name server for the internet (providers name server) nor the internal one take care of the other area.
