HANA – hdbcons first aid hacks
Jens Gleichmann • 1. Februar 2021
This is a subtitle for your new post
A tool which got more and more power since HANA 2.0 was released is hdbcons. It should only be used by experienced admins and should be tested in non-prod systems, because it can produce system crashes. There are several known issues documented in notes which describe scenarios you should avoid the usage of hdbcons in prod systems.
This blog won’t describe the full functional scope (see the central hdbcons note 2222218). I will show some general use cases which are not well known, but should be kept in mind for scenarios I call ‘HANA first aid’. At the end of the blog you will also get an example script for such a troubleshooting situation.

SAP HANA News by XLC
The topic of HANA performance is one of the most discussed topics in nearly every single SAP project we are involved. Performance has always been an important aspect in general; however, particularly when switching databases or application releases - whether moving from anyDB to HANA or, more specifically, from ERP on
There are multiple DMO scenarios and use cases. We heard of many confusions and mixed up statements which we want to order:
SUM can not only update software components, but can also execute a database migration (for ABAP based systems)
DMO used to be heterogeneous (change of DB). Now you can use DMO with system move (also on-prem to target on-prem) to migrate and convert ECC on HANA to S/4 or just update/upgrade S/4 and move it to another location like other DC or other instance in one step.
The DMOVE2S4 is just to move and convert to the cloud in one step. This includes also anyDB source systems and downtime-optimization techniques (doDMO and doC).

Please notice that when you want to run HANA 2.0 SPS07, you need defined OS levels. As you can see RHEL7 and SLES12 are not certified for SPS07. The SPS07 release of HANA is the basis for the S/4HANA release 2023 which is my recommended go-to release for the next years. Keep in mind that you have to go to SPS07 when you are running SPS06 because it will run out of maintenance end of 2023.

An inverted individual index is a special type of SAP HANA index which can only cover unique indexes. This includes all primary key structures. Unlike traditional column store indexes on more than one column (inverted value, inverted hash) an inverted individual index (Inv Idv Idx) doesn't need a dedicated concat.

SAP HANA systems may experience high swap usage, hangs, or performance issues when THP (Transparent Huge Pages) is enabled with "madvise". This occurs on multi-NUMA node systems where one or more NUMA nodes are close to full memory usage while others have plenty of free memory, and counters for THP allocations, direct
Transparent Huge Pages (THP) with madvise can trigger high swap usage, performance issues, or even system hangs on multi-NUMA systems.
