Summary of Topics • Upgrade: Preparation, Update and Post-tasks • HANA2 Cockpit: • Installation • Configuration • Manager • Resources • Groups • Monitoring and Administration • Security • Offline Administration • Performance Management • Capture and Replay • SAP HANA Options Author: Terry Kempis Editor: Linh Nguyen ITConductor.com 3
- 4. Preparation • Operating System Requirements RHEL for SAP HANA 7.2, or SLES for SAP applications 12 SP1 • Make sure to update to the latest components to avoid error below The operating system is not ready to perform gcc 5 assemblies rpm package 'libgcc_s1' needs at least version 5.3.1. (current version = 5.2.1+r226025) rpm package 'libstdc++6' needs at least version 5.3.1. (current version = 5.2.1+r226025) For more information, see SAP Note 2338763. Author: Terry Kempis Editor: Linh Nguyen ITConductor.com 4
- 5. Preparation – 2 • Download and Extracting the downloaded components Use hdblcm if the version has the option ‘- action=extract_components’ Another option is to download hdblcm_prepare.sh from OSS note 2078425 and run it. Author: Terry Kempis Editor: Linh Nguyen ITConductor.com 5
- 6. Preparation - 3 The process of upgrading to HANA2 is similar to the normal SPS release upgrade. Note that there is a ‘minimal’ source system requirement to upgrade to HANA2. Some of the steps before the actual upgrade • Stop data replication • Stop the ABAP connected to the HANA system • As <sid>adm, stopsap R3 • Create a complete backup of the database. For MDC, systemDB and tenant DBs. Author: Terry Kempis Editor: Linh Nguyen ITConductor.com 6
- 7. Database Update - 1 There are several ways of updating an SAP HANA System. The procedure used in this document used the command line As root, Go to the extracted folder containing the hdblcm /mnt/software/SAP/HANA2/extracted/SAP_HANA_DATABASE ./hdblcm -component_root=/mnt/software/SAP/HANA2 /extracted/SAP_HANA_DATABASE -install_hostagent=No (Note: the install_hostagent=No is to bypass installation of hostagent if it already has the latest version. Also, the SAP_HANA_DATABASE does not contain the hostagent binaries – so it just waits on ‘Preparing package ‘saphostagent setup’ if install_hostagent=No is not specified!)

- 10. HANA2 Cockpit - Installation 1 • A new version of HANA Cockpit is delivered with HANA2. • In previous version, the HANA Cockpit is installed during the database version installation, through delivery unit. • HANA2 cockpit is installed using hdblcm, as a separated task - as ‘stand- alone’ – not directly linked to a specific database, and it can be used to administer and monitor several databases running on SAP HANA 2.0 or HANA 1.0 SPS12. • Note that some tasks still need to be done through HANA Studio Author: Terry Kempis Editor: Linh Nguyen ITConductor.com 10 HANA2 Cockpit HANA2 SPS00 HANA1 SPS12
- 11. HANA2 Cockpit – Installation 2 • The minimal requirement for HANA2 cockpit is 16Gb of memory, but suggest to have at least 32Gb • We recommended that you install HANA2 Cockpit on its own server. Installing it with another HANA database can cause memory and CPU contention – and can make the HANA database’s indexserver to hang • Note that with HANA2, the HANA Cockpit still appears in the HANA Studio. But invoking it it through HANA Studio will result with error below. Author: Terry Kempis Editor: Linh Nguyen ITConductor.com 11
- 12. HANA2 Cockpit – Installation 3 • Download the HANA2 Cockpit package • Extract the package, in this example, hdblcm_prepare.sh is used. Note that since folder ‘extracted’ already exist, another folder ‘extracted1’ is created Author: Terry Kempis Editor: Linh Nguyen ITConductor.com 12
