SAP HANA and In-Memory Business Data Management

0 1

s you probably know the is a new tool in SAP HANA SP6 c alled HANA Lifecycle Manager (HLM) . I have beenreceiving some questions how to get f rom using SUM or even hdbupd to using HLM. First of all I recommend t hat youread the official SAP HANA Update Guides on http://help.sap.com/hana simply to understand HLM and what optionsHLM gives you.

hen I first looked at SAP HANA SP6 the update path to HLM was not quite so clear to me after reading the updateuides. My first test included updating SAP HANA to revision 60 using SUM SP5 Patch 5, however after the update I

had to install HLM manually….. Not what I expected. With a new SAP HANA SP6 installation using the Unified InstallerHLM will be installed by default, so no additional steps are needed to get HLM if the unified installer is used (as it shouldbe).

Fortunately I have friends in our SAP Sofia location! Albena Zaharieva presented a number of options and I did spendome time this week testing what I expect to be the most common scenario’s at customers. I mainly tested updatingrom SAP HANA SP5 (standalone and scale out), but also one SAP HANA SP4 standalone instance.

Scenario A: you have been using SUM to update SAP HANA and want to update to the latest SP6 revision and installHLM. You will need the sapadm and <si d>adm passwords, but not root.• Make sure you use the latest SAP HANA Studio.• If you download patches manually, make sure the latest SUM, HLM and saphostagent patches are included.• The minimum versions are SUM SP5 Patch 7, saphostagent version 153 (I used 155), and HLM SP6 (I used HLM SP6patch 1). Also see note 1836498 for minimum versions.• Run SUM and let SUM update itself to the latest patch level by starting the stack or revision update.• After SUM restarts, there will be an option to install HLM.• OR: follow scenario B steps instead, these will also work ?

Scenario B: you received a new server with an older SAP HANA revision (i.e. 53) and you want to keep things simpleby bypassing SUM configuration. Or, you have continued to use hdbinst (Oh no!) and you want to bypass SUM to get toHLM. Note: that you will need the root password for this option.• Update saphostagent to at least version 153 (I tested with version 155). This is a manual step for example using rpm or'saphostexec -upgrade'• Install HLM manually as described in the SAP HANA Update guide chapter 6.1. Note that you need root to do this!• Start HLM perspective (lifecycle management) and proceed with the update to SP6.

Both scenario’s worked, in my humble opinion scenario B was easier. Overall I like to use HLM to update SAP HANAnd think that development did a good job. The HLM options to use st udio, browser, and even command line provides a

lot of flexibility.
