Get C_DBADM_2404 Dumps : Verified SAP Certified Associate - Database Administrator - SAP HANA

To create the COCKPIT MONITOR technical user in SAP HANA 2.0 SPS07, specific privileges are required to ensure the user has appropriate access to system data without compromising security. The correct privileges required are SELECT on the _SYS_TELEMETRY schema (B) and SELECT on the _SYS_STATISTICS schema (D). These privileges enable the technical user to access crucial system performance and monitoring data stored in these schemas, which is vital for effective monitoring and analysis tasks. MONITOR ADMIN (A) is more of a role that encompasses broader administrative privileges, and CATALOG READ (C) provides general access to the catalog objects, which is not specific enough for the creation of a technical user focused on monitoring.References= This determination is derived from the SAP HANA security and user management guidelines, particularly related to the creation and management of technical users within the SAP HANA system.

User Management

The prerequisites that must be fulfilled when recovering a tenant database include:

• The tenant database must be stopped before the recovery starts: Ensuring the database is not running is crucial to avoid conflicts and data corruption during the recovery process.
• The logon credentials of the system database user must be available: This is necessary because recovery operations often require administrative privileges, and the system database user typically has the required level of access.

References=SAP HANA recovery procedures and prerequisites are thoroughly detailed in the SAP HANA administration guide, which stipulates the necessary conditions and user permissions for successful database recovery operations.

You can resume the failed recovery of your productive SAP HANA tenant database in the following situations:

• An aborted recovery of a delta data backup: Resuming from a delta backup is possible because these backups capture changes since the last full or another delta backup, allowing the recovery process to continue from the last successful point.
• An aborted recovery of a log backup: Log backups contain all the transactions since the last log or data backup. If the recovery from these backups is interrupted, it can be resumed because the log contains all necessary information to bring the database to a consistent state up to the point of failure.

References=SAP HANA backup and recovery documentation explains the mechanisms and capabilities of the database's recovery features, including scenarios where recovery processes can be resumed after interruption.

Backup and Recovery

When using the SAP HANA database explorer to import catalog objects, you can source files from:

• Data lake files: Import objects directly from storage solutions categorized under data lakes.
• Local computer: Allows the uploading of files from a user’s local system to the database.
• Google Cloud Storage: Supports integration with Google Cloud Storage, enabling the import of objects stored on Google's cloud services.

References=SAP HANA database explorer capabilities and supported data sources are detailed in the SAP HANA developer guides and database explorer documentation.

The default single sign-on method when usinghdbsql, the command line interface for SAP HANA, is Kerberos based. This method leverages the Kerberos protocol to authenticate users without transmitting passwords, enhancing the security of connections especially in enterprise environments where Kerberos is commonly used as part of the security infrastructure.References= SAP HANA Administration and Security documentation, which discusses authentication mechanisms supported by SAP HANA including the use of Kerberos for single sign-on.
