Which information is stored in the SYSTEMDB of an SAP HANA multitenant database container system?

The SYSTEMDB in an SAP HANA multitenant database container (MDC) system serves as the management layer for all tenant databases. It contains critical metadata and configuration information necessary for the administration and management of the entire system, including monitoring data from all tenant databases.

By storing monitoring data, the SYSTEMDB helps administrators oversee the performance and usage of each tenant database, allowing for efficient resource management and optimization. This centralization of monitoring information gives a comprehensive view of user activities, resource consumption, and system health across the entire landscape, which is essential for DBAs maintaining the multitenant environment.

Other choices, while relevant to system operations, do not accurately describe the specific role of the SYSTEMDB. Landscape topology data, current user activity logs, and database connection details are aspects of system operation but are not the primary focus or storage responsibilities of the SYSTEMDB itself. These other aspects may be managed or logged elsewhere within the HANA system.
