What’s New?

Converting an SAP HANA System to Support Multitenant Database Containers

SAP HANA SPS 9 introduced the multitenant database container concept, where a single SAP HANA system contains one or more SAP HANA tenant databases. This allows for an efficient usage of shared resources, both hardware and database management.

At install time, you select the SAP HANA database mode: single container or multiple containers. Should you want to change the mode after the installation you have to perform a conversion. In earlier revisions, this task was performed on the command line with the tool hdbnsutil, as you can view in the following tutorial video:

As of SPS 12, an SAP HANA system can now be converted to support multitenant database containers using the SAP HANA database lifecycle manager (HDBLCM) resident program. With every installation of SAP HANA, hdblcm is included and enables you to perform common post-installation and configuration tasks. The tool is hosted by the SAP host agent and not, like the SAP HANA cockpit, by the SAP HANA database.

The Convert to Multitenant Database Containers task is available for all interfaces: web, windows and command line, but the web interface allows you to set advanced parameters:

• Import delivery units into the system database (default = Y)
• Do not start instance after reconfiguration
• Do not start tenant database after reconfiguration
• Set instance startup and shutdown timeout

During the conversion, the original system database is configured as tenant and a new system database is created. This operation is quick as we only need to shutdown the SAP HANA database, update a few settings and restart the instance. Importing the standard HANA content (web IDE, SAPUI5, cockpit, etc.) takes most time and can optionally be postponed or not performed all together.

Note that the conversion is permanent.

The web UI allows to set advanced parameters.

Adding and Removing Host Roles

It is now possible to add and remove host roles after installation in a single-host or multiple-host SAP HANA system using the SAP HANA database lifecycle manager (HDBLCM) resident program.

As of SPS 10, you have the option to install SAP HANA systems with multiple host roles – including database server roles and SAP HANA option host roles – on one host, or give an existing SAP HANA host additional roles during system update. This enables you to share hardware between the SAP HANA server and SAP HANA options. This concerns the MCOS deployment type: Multiple Components One System.

Typical roles are worker and standby and exist for the the SAP HANA database, dynamic tiering, accelerator for SAP ASE, and the XS advanced runtime. Additionally roles are available for smart data streaming and remote data sync.

Database worker is the default role. For distributed systems, with multiple SAP HANA hosts, systems can assigned the standby role for High Availability purposes.

System Verification Tool

You can check the installation of an SAP HANA system using the SAP HANA database lifecycle manager (HDBLCM) resident program in the command-line interface for troubleshooting. The check tool outputs basic information about the configuration of the file system, system settings, permission settings, and network configuration and you can use the generated log files as a reference in the case of troubleshooting.

Documentation

A new guide is available that documents how to configure, manage, and monitor an SAP HANA system that supports SAP HANA multitenant database containers
