In an SAP HANA MDC, how many System IDs (SID) does a multiple database container have?

In a multiple database container (MDC) environment within SAP HANA, there is a single System ID (SID) allocated for the entire database system. The SID uniquely identifies the SAP HANA system and is consistent across all databases within that container.

The design of MDC allows for the creation and management of multiple databases within the same system or instance while retaining a unified management structure. Each database in an MDC can contain its own set of tables and data, but they share the same SID, allowing for streamlined administration and reduced overhead.

Having one SID simplifies the identification of the databases that belong to the same container and helps facilitate operations such as backups and transport operations across the databases. Therefore, the choice indicating that there is one SID accurately reflects the architecture of a multiple database container in SAP HANA.
