Update news! Best Practice for SAP NetWeaver HA on SLES for SAP 12 and 15
In the first week of April we published a new and an updated version of our Best Practices guide. Therefore an update version for SAP NetWeaver HA on SUSE Linux Enterprise Server for SAP Applications 12 is available. And a new version for SAP NetWeaver HA on SUSE Linux Enterprise Server for SAP Applications 15 is available.
As a result you can find guides on our website:
SUSE Linux Enterprise Server for SAP Applications 12 (Update)
SUSE Linux Enterprise Server for SAP Applications 15 (New)
The updated guide and the new guide describe planning, set up, and basic testing of the SAP certified “SAP NetWeaver Enqueue Replication 1 High Availability Cluster” based on SUSE Linux Enterprise Server for SAP Applications.
The most important improvements are:
- firstly: updated command’s for test procedures
- secondly: document is now available in 4 different variants for reading
- thirdly: Best Practice is adapted for SUSE Linux Enterprise Server for SAP Applications 15
- further: implementing feedback
In short, the new guides are better as before and replacing the old version.
This is Fabian and Bernd from SAP LinuxLab.
Why is it best practice to have ASCA/ERS and Application and Databases on different nodes in cluster?
the short answer is, you avoid additional application / business impacts if one of your cluster node for ASCS or ERS get fenced by the cluster.
There are multiple ways to cover multiple scenarios and depending on the risk or impact you are willing to suffer you can adjust the setup as much as possible. Reducing the infrastructure and summarizing services running on less system will extend the complexity and may have influences to each other which must be carefully tested and validate. A overall testing is key for productive systems and more services running on a cluster controlled systems will extend the cluster testing as well.
