1 About the Release Notes

The most recent version of the Release Notes is available online at https://www.suse.com/releasenotes.

These Release Notes are identical across all supported architectures.

Entries can be listed multiple times if they are important and belong to multiple sections.

Release notes usually only list changes that happened between two subsequent releases. Certain important entries from the release notes documents of previous product versions may be repeated. To make such entries easier to identify, they contain a note to that effect.

Repeated entries are provided as a courtesy only. Therefore, if you are skipping one or more service packs, check the release notes of the skipped service packs as well. If you are only reading the release notes of the current release, you could miss important changes.

The following definitions apply:

L1

Problem determination, which means technical support designed to provide compatibility information, usage support, ongoing maintenance, information gathering and basic troubleshooting using available documentation.

  • Packages that require an additional customer contract

SUSE will only support the usage of original packages. That is, packages that are unchanged and not recompiled.

2.6 Technology Previews

Technology previews are packages, stacks, or features delivered by SUSE which are not supported. They may be functionally incomplete, unstable or in other ways not suitable for production use. They are included for your convenience and give you a chance to test new technologies within an enterprise environment.

Whether a technology preview becomes a fully supported technology later depends on customer and market feedback. Technology previews can be dropped at any time and SUSE does not commit to providing a supported version of such technologies in the future.

Give your SUSE representative feedback about technology previews, including your experience and use case.

2.7.2 Externally Provided Documentation

3 SUSE Linux Enterprise Server for SAP Applications for POWER

3.1 On POWER, the Minimum Certified Revision of SAP HANA 2.0 SPS04 Is Revision 41

On SLES for SAP 15 SP1 for POWER, the minimum certified revision of SAP HANA 2.0 SPS04 is revision 41. For earlier revisions of SAP HANA 2.0 SPS04, there is a compatibility issue.

However, this issue does not affect other versions of SAP HANA, such as version SAP HANA 2.0 SPS03, which is supported.

4 Added Packages

4.1 Package insserv-compat Has Been Added to SAP Application Server Base Pattern

SAP applications depend on the sapinit System V script. Other third-party software not yet updated to include systemd unit scripts may also depend on System V init scripts. On its own, systemd does not support System V init scripts anymore.

The package insserv-compat adds compatibility with System V init scripts to systemd and can be used both SAP and non-SAP applications. This package is now also included in the SAP Applications Server Base pattern.

That way, insserv-compat will provide System V compatibility until SAP and other third parties fully adopt systemd unit scripts.
