Using the backup scheduler in the SAP HANA cockpit, you can schedule the following types of backups:

• Incremental backup: Captures only the changes since the last complete backup, minimizing storage requirements and speeding up the backup process.
• Complete backup: Provides a full backup of the entire database, ensuring that all data is captured at a specific point in time.
• Log backup: Regularly backs up the transaction logs, allowing for point-in-time recovery and minimizing data loss in the event of a failure.

References=The SAP HANA cockpit's backup scheduler functionality and options are described in the SAP HANA Cloud backup and recovery guides, detailing how to configure and manage various types of backups.

Backup and Recovery

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

To ensure that a consistent database status is saved using data snapshots, the appropriate action is to:

• Trigger a savepoint: This operation synchronizes the database's in-memory state with persistent storage, ensuring that the snapshot reflects a consistent state of the database.

References=SAP HANA documentation on backup and recovery methods emphasizes the importance of savepoints in creating consistent and reliable data snapshots.

To analyze performance issues in SAP HANA systems, especially in environments where third-party software installations are restricted, activating the Kernel profiler trace is the most effective approach. The Kernel profiler provides detailed insights into the database operations at a low level, capturing performance data about database procedures and commands. This trace is invaluable for understanding the performance characteristics of SAP HANA operations and identifying bottlenecks without the need for additional software layers.References= SAP HANA performance monitoring and tuning documentation.

Monitoring and Troubleshooting

All database objects deployed using the SAP HANA Deployment Infrastructure (HDI) are owned by the container-specific technical user. This technical user is automatically created for each HDI container and is distinct from regular database users or administrators, ensuring that the operations within the container are isolated and secure. This approach allows for precise permission management and enhances security by limiting access to the container's resources.References= SAP HANA HDI documentation detailing the role of technical users and their association with HDI containers.

Database Security

The SAP HANA Cloud, SAP HANA database runs in SAP BTP within the "SAP HANA Cloud Central." This is the central management hub for SAP HANA Cloud instances, providing tools and interfaces for configuration, monitoring, and administration of database resources on the SAP Business Technology Platform.References= SAP BTP documentation and SAP HANA Cloud guides, which describe the integration and management of SAP HANA within the broader SAP cloud ecosystem.

SAP HANA Architecture

When upgrading an SAP HANA Cloud, SAP HANA database instance, the possibilities include:A. Upgrade the replica first, which involves applying the upgrade to a secondary replica or system to minimize downtime and risk to the primary system during the upgrade process.B. Select the version to install, providing flexibility in managing the upgrade path and aligning with specific business and system requirements for the version compatibility.Upgrading without restart and reverting to a previous version are not typically supported operations in SAP HANA Cloud, as these actions involve complexities that current technologies and strategies aim to manage differently.References= SAP HANA Cloud administration guide, detailing procedures and options for upgrading database instances within the cloud environment.

SAP HANA Architecture

In an SAP BTP account, you can provision the following types of SAP HANA Cloud instances:

• SAP HANA database: The primary database service provided in SAP HANA Cloud.
• Data lake: A scalable storage solution integrated with SAP HANA Cloud, offering large-capacity data management.

References=Provisioning options and service descriptions for SAP HANA Cloud are documented thoroughly in SAP BTP service guidelines, detailing supported instance types such as databases and data lakes.

Provisioning SAP HANA

In the SAP HANA Cloud, SAP HANA database, user groups can be assigned various entities to manage and control access efficiently. The correct answers are Permissions (C) and Roles (D). Permissions provide detailed control over what specific actions a user group can perform on database objects, applications, or data. Roles encompass a collection of permissions tailored to facilitate specific job functions or responsibilities, which can be assigned to a user group to streamline authorization management. Assigning Password policies (A) to a user group is not typically done, as password policies are generally set at a system-wide level rather than per group. Assigning individual Users (B) to a user group is a reverse relationship where users are members of groups, not an assignment to the groups themselves.References= This response is based on standard practices for user group management within SAP HANA Cloud as outlined in SAP documentation and security management best practices.

User Management

The feature used to dynamically control SAP HANA database workloads per client session is Admission Control. This feature allows administrators to manage and control the resource allocation and workload prioritization for different sessions, thereby preventing system overloads by limiting the number of concurrently executing high-demand queries and maintaining system stability and performance.References= SAP HANA Performance Monitoring and Tuning Guide.
