My point of view:


In my company we used the HANA server to COPA. the SAP CO-PA Accelerator, powered by SAP HANA, empowers organizations with easy access to data to make timely decisions.

Before upgrading the HANA DB from SPS06 to SPS08 we have a lot of memory and CPU consuming, the total memory available on the host is used, CPU resource are running low,

And more important problem we did not expect them.

For you can feel it, I I'll put some pictures here:

Picture 0.1 – DBACOCKPIT administration

Picture 0.2 – Alerts from DBACOCKPIT

Picture 0.3 – HANA studio administration

After the upgrade like a magic the CPU and memory consuming are decreased, and the system works so fast!!

Tasks you need to take care before you start the upgrade


Before I start the upgrade I had to upgrade GCC 4.7 (2001528) and to Run script keepTransaction.py (1919033) and script MERGE_ALL_TABLES  (1919034) see details in Prerequisites and planning.

  • In order to run the SAP HANA Database Revision 80 (or higher) on SLES 11, additional operating system software packages are requiredTherefore you need to install an additional runtime environment for GCC 4.7 Before you start the upgrade or the installation of Revision 80 or higher, please check out SAP Note 2001528.
  • If you upgrade from a Revision prior to SPS6, first upgrade your system to the latest SPS6 Revision (69.07) before upgrading to Revision 82.00. (X)
  • Please make sure to read note 2052914 (ODBC driver issue after upgrade to Revision >= 82) before doing the upgrade
  • Before you start the upgrade from Revision 64, 65 and 66, please check out SAP HotNews Note 1918267. (1919034 - Related to 1918267: How to run procedure MERGE_ALL_TABLES) – Please check details below

Before starting the update for the components in your SAP HANA landscape several prerequisites have to be fulfilled.

Make sure you fulfill the following prerequisites: from SAP_HANA_Server_Installation_Guide_en.pdf

  • If you are performing an offline update, you have all the necessary installation files for the individual components.
  • You have a valid, permanent SAP license for the SAP HANA database.
  • You have user names and passwords for the following users:
  • <sid>adm user
  • sapadm user
  • S-user for the SAP Service Marketplace (SMP)

  • Run script keepTransaction.py – note number 1919033
  • Run  MERGE_ALL_TABLES – Note number 1919034


Perform an Update on the SAP HANA System


The SAP HANA lifecycle management tool hdblcm(gui) is the recommended tool to update an SAP HANA system. With the SAP HANA lifecycle management tool hdblcm(gui) you perform the update from the local host.

To update an SAP HANA system from a remote host you use the SAP HANA lifecycle manager (HLM).

Update Process: from SAP_HANA_Server_Installation_Guide_en.pdf


Before updating the SAP HANA components, make sure that no read or write processes are running on the SAP HANA database. Perform the update process in offline mode during a business downtime. After the update, you have to start SAP HANA and its components again.

This is a general sequence of the steps you have to perform:


  1. Stop all processes.
  2. Make a system backup if necessary.
  3. Perform an update.
  4. Update the depending components.
  5. Perform the post-update steps.
  6. Restart all processes.

Upgrade Procedure:

Errors and solution:


Upgrade Error:


Picture 4.0

You can see the error I get when I start the upgrade. (Picture 4.0)

Please follow the following item from note #1995791:

Validity: there was a file /usr/sap/HAN.hdbupgrade dated last year
Which was used when the database was upgraded to REL 60. It appears
that the previous upgrade was still in a "hung" state which causes the
error message below (SAP HANA Database installation kit
'1.00.60.379371' required)
during the manual update as well as using HLM.
Solution: the solution is to mv the file to HAN.hdbupgrade.old and
resume the update. Once resumed a new file HAN.hdbupgrade with recent
date will be generated.

Update Studio Error:

Picture 5.0

Error when I try to update the studio from: Help – Install New software Picture 5.0

Solution in Note number - 2026732 - Can't update SAP HANA Studio via Update Site

Cause:

If the differences between studio revisions is great, the Eclipse installer cannot resolve the differences in package dependencies.

Solution:

Users will need to manually upgrade the SAP HANA Studio

I hope this guide will help you to start thinking about upgrading your HANA Server - good luck

Thanks you for reading my document.
