In the Local Work Process Overview, the information displayed for a particular work process over a considerable time period is as follows: Running, Sequential Read, and a specific table name. What does this tell you?

A There may be an expensive SQL statement which accesses the table and can be analyzed more closely in the Database Process Monitor.B There may be a wait situation in the dispatcher, preventing a connection to the database. The dispatcher queue should be analyzed more closely.C There may be an exclusive lock wait that you can detect in the monitor for exclusive lock waits.D There may be a network problem between the application server and the database server.

Which of the following statements are correct?

A The CPU time is measured by the operating system of the applciation server.B The database time is measured by the database system.C High network times for data transfers betweent eh presentation server and the applciation server are reflected in an increased response time in the Workload Monitor.D High network times for data transfers between the application server and the database server are reflected in an increased response time in the Workload Monitor.E The roll-out time is not part of the response time because the roll-out of a user occurs only after the answer has been sent to the presentation server. Nevertheless, it is important for the performance of the SAP system to keep the roll-out time to a minimum, as during the roll-outs, the SAP work process remains occupied.

How is the term load defined in the SAP environment?

A The load generated by a particular process is defined as the percentage of time which that process occupies the CPU of a computer, and can be monitored in the Operating System Monitor as CPU utilization.B Load is the sum of response times. Thus, total load refers to the total response time, CPU loads refers to toal CPU time, and database load refers to the total database time.C Load mean the number of transaction steps for each unit of time.

The Worklad Monitor displays increased wit times for the dispatcher such that Av. Wait time is much greater than 50ms. What does this tell you?

A There is a communication problem between the presentation servers and the dispatcher of the application server - for example, a network problem.B There is a general performance problem - for example, a database problem, a hardware bottleneck, or insufficient SAP extended memory; or there are too few SAP work processes. This statement does not provide enough information to pinpoint the exact problem.C An increased dispatcher wait time is normal for an SAP system. It protects the operatin system from being overloaded, and can be ignored.

Which statements can be made on the basis of the SAP statistics records?

A If a user action involves several SAP components (ABP, J2EE, ITS, etc.) an action ID (referred to as the passport) enables you to trace the user action across the components.B The statistics records contain information on the response time of individual program components (function module calls or methods in the case of ABAP, class in the case of Java)C The global statistics records contain the response time of a corresponding component (ABAP, J2EE, ITS, etc.), the CPU time needed by the component, and the response time of additional components that are called by the component that writes the statistics record.D On the basis of the statistics records, you can make statements on the performance of the business processes such as the cash flow in financials or the delivery reliability in logistics.

Which of the following statements is correct with regard to Java Application Request Measurement (JARM)?

A JARM provides statistics on Java transactions across several user interactions.B JARM provides statistics on the calls of Java classes that are instrumentalized as JARM components and it is thus a measurements method with a higher resolution compared to the SAP statistics record.C JARM is the name of SAP statistics records that are generated by the J2EE engine.

Where should background work process be configured?

A Background work processes should always be located on the database server. Otherwise, the runtime of background programs will be negatively affected by network problems between the database server and the application server.B If background work processes are not located on the database server, they must all be set up on a dedicated application server known as the background server.C Background work processes can be distributed evenly over all the application servers.

How should you configure and monitor the dynamic user distribution?

Which SAP profile parameters define the amounts of extended memory and heap memory that should be kept in the physical main memory or in the paging file?

A SAP extended memory is always kept completely in the physical memory, and SAP heap memory is created in the operating-system paging file.B None. The memory areas in the physical main memory and the paging file (that is, the page-out or page-in process) are automatically distributed by the operating system. An application program (such as SAP or a database program) cannot influence the distribution.C The SAP profile parameter ztta/roll_extension defines the amount of SAP extended memory in the physical memory. The parameters abap/heap_area_dia and abap_heap_are_nondia define the amount of SAP heap memory.

Which of the following can cause an SAP instance to not start, or to start with an error message, after you change SAP parameters for memory management?

A The program buffer size specified in the parameter abap/buffer_size exceeds the limit that exist due to address space restrictions.B There is not enough physical memory to allow the new settings.C The paging file is not large enough to allow the new settings.D The amount of SAP extended memory specified in the parameter em/initial_size_MB exceeds the limit that exist due to address space restrictions.

Which of the following factors are reasons for not activating full buffering on a table?A The table is very large.B The SQL statement that is used most frequently to access the table contains the first two of the five key fields in an EQUALS conditions.C The table is changed often.

Which of the following statements are correct with regard to buffer synchornization?A During buffer synchronization, the application server where the change occurred sends a message through the message server to implement the change in the respective buffered table on the other application servers.B After a transaction changes a buffered table, the transactions must first be completed with a database commit before the table can be reloaded into the buffer.C In a central SAP system, the SAP profile parameter rdisp/bufrefmode must be set to sendoff, exeoff.D In a central SAP system, the entries in the table buffer are never invalidated, because the table buffer is chnaged synchronously after a database change operation.

Which of the following statements are correct with regard to locks and SAP enqueues ? A An SAP enqueue locks one or more tables in the database .B After an SAP enqueue has been placed, the corresponding database table can still be changed by an update request coming from programs such as customer-developed ABAP reports..C A database lock is usually released at the end of a transaction step, while an SAP enqueue is usually released at the end of an SAP transaction.D A database lock that lasts too long can cause an SAP system stanstill.

A Request data from an SAP systemB Pass data to an SAP systemD Access business processes in SAP systems

You can BAPIs to access business processes in an SAP system and to request and transfer data between systems. GUI functions cannot be transferred to third-party products.

TRUE

BAPIs are nothing more than special, remote-enabled function modules. They can therefore also be addressed using RFCs.

Business APPLICATION Programming Interfaces are specialized FUNCTION modules. They are accessed using the RFC interface . They are created and managed using the FUNCTION Builder.

APPLICATION, FUNCTION, RFC, FUNCTION.

You can start the Business Object Repository using transaction code "BAPI", and the Function Builder using the transaction code "SE37"

A Appropriately configured business processes can be partially automatedB Appropriately configured business processes are executed in consistent sequencesC The right employee receives the right work at the right timeD Your workflow-supported business processes are handled more efficiciently

Supporting business processes with workflow enables the work steps that belong to these processes to be handled on a partially automated basis. These steps are assigned in consistent sequences to the appropriate employee at the right point in time. This enhances process efficiency. Using workflow obviously does not guarantee that the programs you write will always run without errors.

A The CPU time is measured by the operating system of the applciation server.D High network times for data transfers between the application server and the database server are reflected in an increased response time in the Workload Monitor.E The roll-out time is not part of the response time because the roll-out of a user occurs only after the answer has been sent to the presentation server. Nevertheless, it is important for the performance of the SAP system to keep the roll-out time to a minimum, as during the roll-outs, the SAP work process remains occupied.

B Load is the sum of response times. Thus, total load refers to the total response time, CPU loads refers to toal CPU time, and database load refers to the total database time.

B There is a general performance problem - for example, a database problem, a hardware bottleneck, or insufficient SAP extended memory; or there are too few SAP work processes. This statement does not provide enough information to pinpoint the exact problem.

A If a user action involves several SAP components (ABP, J2EE, ITS, etc.) an action ID (referred to as the passport) enables you to trace the user action across the components.C The global statistics records contain the response time of a corresponding component (ABAP, J2EE, ITS, etc.), the CPU time needed by the component, and the response time of additional components that are called by the component that writes the statistics record.

B The user whose actions are being traced should not run multiple programs concurrently.C You should perform the SQL trace on a sceond execution of a program because the relevant buffers are then already loaded.

B For programs with high CPU requirements

B JARM provides statistics on the calls of Java classes that are instrumentalized as JARM components and it is thus a measurements method with a higher resolution compared to the SAP statistics record.

C Background work processes can be distributed evenly over all the application servers.

A The GUI time is greater than the roll wait time.D The roll wait time is normally greater than zero, although it can also be zero.

B The RFC time is greater than the roll wait time.E The roll wait time is always zero.

A Use the ITS administration and monitoring tool or the central CCMS Monitor to check if all work processes or sessions are running on the ITS or if the CPU is constantly running.B In the Work Process Overview for the connected SAP system, check if all work processes are running.C Using a performance trace and the single record statistics, analyze the response time of the connected SAP system and compare it with the user-measured response time for the presentation server.D Using an analysis tool on the presentation server (for example, PERFMON), check the data transfer volume to the browser and the compilation time for an HTML page on the brower, and compare the required time with the total response time.

B None. The memory areas in the physical main memory and the paging file (that is, the page-out or page-in process) are automatically distributed by the operating system. An application program (such as SAP or a database program) cannot influence the distribution.

A The program buffer size specified in the parameter abap/buffer_size exceeds the limit that exist due to address space restrictions.C The paging file is not large enough to allow the new settings.D The amount of SAP extended memory specified in the parameter em/initial_size_MB exceeds the limit that exist due to address space restrictions.

A The table is very large.C The table is changed often.

B After a transaction changes a buffered table, the transactions must first be completed with a database commit before the table can be reloaded into the buffer.

B After an SAP enqueue has been placed, the corresponding database table can still be changed by an update request coming from programs such as customer-developed ABAP reports..C A database lock is usually released at the end of a transaction step, while an SAP enqueue is usually released at the end of an SAP transaction.D A database lock that lasts too long can cause an SAP system stanstill.

C The ATP server reduces the number of accesses to tables RESB and VBBE .

B) Gaps occur on the number assignment when using buffered number ranges. You must check whether these gaps are permitted by business law and are acceptable from a business viewpoint.C If the quantity of numbers in the buffer is to small, performance problems will result, particulary during mass data entry using Batch input or Fast input.

A) they can lead to hardware bootlenecks (a.CPU or I/O bootleneck ) and negatively affect the runtime of other SQL statementsB) They can occupy a lot of space in the data buffer of the database,displace objects that are needed by other SQL statments, and negatively affect the runtime of other SQL statments.D) if they are performed after database locks were set b y the same program, this can cause exclusive locks wait situations in the database , which can cause a brief system standstill.

C The database optimizer has created an inefficient execution plan- for example, by choosing an inefficient index.D There is no appropriate index for the SQL statement. F A large number of records are being transferred from the database to the ABAP program .
