What is the correct sequence for the restart of the SAP HANA database system?

The correct sequence for the restart of the SAP HANA database system is essential to understand as it highlights the prioritized actions taken to ensure data integrity and system stability.

In the specified sequence, the first step is loading row tables into memory. This is crucial because row tables primarily contain the most frequently accessed and updated data, and bringing them into memory ensures that the database can quickly respond to queries and operations. After this step, the system recovers any open transactions. This ensures that any ongoing operations that were in flux at the time of the restart are completed or corrected to maintain consistency in the database.

The next step involves rolling back any aborted transactions. Any transactions that were not completed correctly are undone to avoid leaving the database in an inconsistent state. This process is critical for maintaining data integrity and ensuring that no partial transactions affect the database's reliability. After handling these transactions, the final step is loading column tables into memory. Column tables are typically used for analytical queries and are brought into memory after ensuring that the immediate operational context (like open transactions) is stable.

The sequence emphasizes maintaining operational performance and data consistency, outlining a logical order that prioritizes immediate usability, transaction consistency, and then analytical capability. Understanding this sequence helps in grasping how the SAP H
