To disable tenant database functionalities, you can use:

• Manage Database Configuration: This tool in the SAP HANA Cockpit allows administrators to configure and manage database settings, including the disabling of specific functionalities within a tenant database.
• Manage Restricted Features: Specifically designed to control the availability of certain features within tenant databases, this tool provides a straightforward interface for enabling or disabling functionalities deemed sensitive or unnecessary.

Database Administration

The SAP HANA cockpit application suited for investigating a system offline situation is the "Troubleshoot Unresponsive System" tool. This tool is designed to diagnose issues when the SAP HANA system becomes non-responsive. It provides guided procedures that help in identifying the root cause of the downtime and suggests possible solutions to bring the system back online, thus serving as a critical resource in crisis scenarios where quick recovery is paramount.References= SAP HANA Cockpit management and monitoring guide.

Monitoring and Troubleshooting

For a tailored data center integration (TDI) installation of a productive SAP HANA database system, it is essential to size the following hardware KPIs:A. DRAM required for the static data memory area, as it determines the amount of main memory needed to hold the active dataset of the SAP HANA database in memory for fast processing.B. Total disk space required for the log volume, which is crucial for maintaining the log entries that record all transactions and database changes, necessary for recovery and durability.Persistent memory (PMEM) for backups and network bandwidth for the storage zone, while important in their own right, are not directly related to initial sizing criteria for DRAM and disk space as per SAP HANA TDI guidelines.References= SAP HANA Tailored Datacenter Integration (TDI) guide which includes details on sizing and planning infrastructure for deploying SAP HANA.
