When starting an SAP system, which step should you begin with?

• A. Start the application server
• B. Start the database
• C. Start the SAP Web Dispatcher
• D. Start system monitoring tools

Answer: (B)

Starting the database is the fundamental first step when initiating an SAP system because the database serves as the central repository for all application data and metadata. The database must be operational before any application components can function properly, as they depend on it for data access and storage. If the database is not running, the application server will not be able to retrieve or manage the data necessary to perform its functions, leading to failures or errors during the startup process. The application server is designed to process business logic and user requests, but it requires a running database to complete these tasks. Similarly, the SAP Web Dispatcher, which manages the distribution of requests between application servers, also depends on the database to serve user transactions effectively. System monitoring tools, while important for overseeing performance and health, cannot operate meaningfully until the underlying database is active and accessible. Therefore, the sequence of starting the database first ensures that all subsequent components can initialize correctly and maintain the system’s integrity from the outset.
