SAP Basis Administration - Basics

Multiple application servers can share a single database server because the database server is designed to handle multiple connections from different application servers simultaneously. Each application server can establish a connection to the database server and perform database operations independently. This allows for efficient resource utilization and scalability in a distributed system architecture.

The skills of Operating System, Database, and Basic Networking are essential for an SAP Basis Administrator to perform their duties effectively. Operating System knowledge is necessary to manage and configure the SAP system on the server. Database skills are required to handle the database management system used by SAP. Basic Networking knowledge helps in troubleshooting network-related issues and ensuring smooth communication between different system components. However, MS Access is not directly relevant to the role of an SAP Basis Administrator, so it is not included as a correct answer.

The correct answers for logging into an SAP server are SAP GUI and a browser. SAP GUI is a graphical user interface that provides a user-friendly way to access the SAP system, while a browser can also be used to access the SAP server through web-based interfaces like SAP NetWeaver Business Client. MS Word and MS Access are not valid methods for logging into an SAP server as they are not designed for this purpose.

MS Access cannot be used as a database in a SAP server because SAP servers typically require a more robust and scalable database system. MS Access is a desktop database management system primarily used for small-scale applications and lacks the scalability and performance capabilities needed for enterprise-level systems like SAP. SAP servers commonly use database systems like Oracle, SAP HANA, and MS SQL, which are designed to handle large volumes of data and provide advanced features required by SAP applications.

The correct answer is "All of the above" because DIA, UPD, and ENQ are all types of work processes. DIA stands for Dialog, which refers to a process that interacts with the user. UPD stands for Update, which refers to a process that updates data. ENQ stands for Enqueue, which refers to a process that manages locks on data objects. Therefore, all three options mentioned in the question are valid work process types.

The statement is true because in SAP GUI, users have the option to enter either the IP address or the application server name to connect to the server. This flexibility allows users to connect to the server using either method, depending on their preference or the available information.

SM50 is the correct T-code used to view all processes. This T-code provides a comprehensive overview of all active processes in the system. It allows users to monitor and manage the status, performance, and resource utilization of individual processes. By using SM50, users can identify any issues or bottlenecks in the system and take appropriate actions to optimize its performance.

The SAP system number concept allows us to create logon groups, which helps in segregating users based on their functional areas. By assigning different system numbers to different logon groups, users from different functional areas can be easily managed and their access can be controlled more efficiently. This concept is particularly useful in large organizations where there are multiple functional areas with different user requirements and access levels.

To connect to an SAP server located in the same network from the SAP GUI front end, three pieces of information are mandatory: the application server name, the instance number, and the SID (System ID). The application server name identifies the specific server within the network, the instance number specifies the instance of the SAP system running on the server, and the SID is a unique identifier for the SAP system. These three pieces of information are necessary to establish a connection between the SAP GUI front end and the SAP server. The SAProuter string, on the other hand, is not required for connecting to an SAP server in the same network.

SAP CRM servers support UNIX, Linux, and Windows 2008 Server operating systems. This means that the SAP CRM software can be installed and run on servers using any of these three operating systems. Windows Vista, on the other hand, is not supported by SAP CRM servers, so it is not a correct answer.

Every Dialog Work Process has built-in memory means that each Dialog Work Process is equipped with its own memory, allowing it to store and retrieve information as needed. This suggests that the statement is true, as it implies that memory is an inherent feature of Dialog Work Processes.

The correct answer is Application Layer and Database Layer. In a three-tier client/server structure, the Application Layer is responsible for handling the user interface and business logic, while the Database Layer is responsible for storing and managing the data. These two layers work together to ensure the smooth functioning of the client/server system. The Performance Layer and Gateway Layer are not part of the three-tier structure and therefore not correct answers.

SM50 is the transaction code used to monitor the SAP system's workload and performance. It provides a real-time overview of the active work processes, allowing administrators to identify performance bottlenecks, resource consumption, and potential issues. ST06 is used for system monitoring and performance analysis, SM04 displays logged-on users, and AL08 displays system log messages.

The statement "Installing an SAP Server in an enterprise is just one day job" is false. Installing an SAP Server is a complex process that requires careful planning, configuration, and implementation. It involves various steps such as hardware and software setup, network configuration, database installation, and system configuration. Additionally, it may require the involvement of multiple stakeholders and technical experts. Therefore, it is not feasible to complete the installation of an SAP Server in just one day.

After authentication, we can perform an activity in a SAP server using T-codes, SAP menu, and through the browser. T-codes are transaction codes that allow users to directly access specific functions or programs in SAP. The SAP menu provides a hierarchical structure of all available functions and activities within SAP. Additionally, users can also access SAP through a web browser, which allows for remote access and flexibility in performing activities in the SAP server. Therefore, all of the options mentioned are valid methods for performing activities in a SAP server after authentication.

The correct answer is "Dispatcher". In a computer system, when a user makes a request, it is first accepted by the dispatcher. The dispatcher is responsible for receiving and distributing the requests to the appropriate components or processes in the system. It acts as a central hub, coordinating the flow of requests and ensuring that they are handled efficiently. Therefore, the dispatcher plays a crucial role in managing and directing user requests within the system.

The correct answer is "All of the above." The SAP Web Application server is run by both ABAP and Java runtime environments, making it capable of supporting applications developed in both languages. It can also function as a middleware, similar to WebLogic, allowing it to integrate with other systems. Additionally, the SAP Web Application server is built-in to various SAP servers such as CRM, SCM, BI, SEM, HCM, ECC, and SRM. Therefore, all of the given options are correct.

SM50 is the correct answer because it is a T-code that can be used to view the active work processes in the system. It provides information about the users currently logged in, the programs they are running, and the status of their processes. This allows administrators to monitor and track user activity in the system.

The combination of MS SQL and Solaris 11 cannot be used in a single SAP Server instance. SAP Server instances are typically run on specific operating systems and databases that are compatible with each other. In this case, MS SQL is a Microsoft database management system, while Solaris 11 is an operating system developed by Oracle. These two components are not compatible with each other, hence they cannot be used together in a single SAP Server instance.

After logging in, whenever a user executes a T-code in an SAP server, an authorization check is done. This means that the system verifies whether the user has the necessary permissions and authorizations to perform the specific task associated with the T-code. This check ensures that the user is only able to access and perform actions that they are authorized to do, maintaining the security and integrity of the system.

SAP HANA server is installed on SUSE OS. SUSE is a popular operating system that is compatible with SAP HANA and provides the necessary environment for running the server. It is specifically designed to support enterprise-level applications like SAP HANA and offers features and optimizations that make it a suitable choice for hosting the server. Therefore, SUSE is the correct choice for installing SAP HANA server.

Business Intelligence, Enterprise Portal, and Master Data Management are all products of NetWeaver technology. NetWeaver is a software stack developed by SAP that provides a platform for integrating various applications and systems. Business Intelligence refers to the tools and processes used for analyzing and reporting data to support decision-making. Enterprise Portal is a web-based platform that allows users to access and interact with business applications and information. Master Data Management involves creating and managing a central repository of consistent and accurate master data across an organization.

The correct answer is "Database buffer". When a user requests for new information, the system first checks the database buffer. The database buffer is a portion of the memory that is used to temporarily store frequently accessed data from the database. By checking the database buffer first, the system can quickly retrieve the requested information without having to access the slower hard drive or go through other processes such as the dispatcher or SPO work process. This helps to improve the overall performance and response time of the system.

T-code SM50 can be used to view the name of the table accessed and the current action on the table.
