So are SAP transactions. Why does the database transaction concept nevertheless not cover all the needs of the SAP system? A An SAP transaction can bundle several database transactions. It is only the result of all of thse bundled database transactions that the data is consistent in business terms. B Due to work process multiplexing, each work process starts a separate database transaction within each dialog step. C This is because SAP developers have not done their job properly D Using the SAP transaction as a structural level above the database transaction significantly imprpoves the performance of your SAP system. 15 SAPTEC Unit 3-9 Where is the lock table?

39 40 SAPTEC Unit 7-1 What is the follow-up product of SAP R/3? PO Guide Chapter 2 Which of the following can cause a CPI bottleneck on the database server? A External processes that do not belong to the database or an SAP instance are running on the database server B The SAP extended memory is configured too small C Work processes that belong to an SAP instance running on the database (for example, background or update work processes) D There are expensive SAL statements - for example, thost that contribute 5% or more ov the entire database load in the Shared SQL Area E The database buffers are set too small, so that data must be continuously reloaded form the hard disks

41

PO Guide Chapter 2 Which of the following are necessary to achieve optimal database performance? A Table analysis (through a program such as Update Statistics) must be regularly scheduled. B The number of SAO work processes must be sufficiently large, so that ther are enough database processes to process the database load. C The database buffers should be sufficiently large. D You should regularly check whether expensive SAL statements are unnecessarily occupying CPU and main memory resources E The datase instance shoul be run only on a separate 42 computer without SAP instances PO Guide Chapter 2 Which points should you take into consideration when monitoring SAP memory management? A The total memory allocated by the SAP and database instances should not be larger than the physical main memory of the computer B The extended memory must be sufficiently large. C If possible, no displacements should occur in the SAP 43 buffers. PO Guide Chapter 2 the Local Work Process Overview, the information In 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.

44

PO Guide Chapter 3 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. 45 PO Guide Chapter 3 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. 46 PO Guide Chapter 3 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.

47

PO Guide Chapter 4 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. 48 PO Guide Chapter 4 What do you have to consider when you perform an SQL trace? A There is only one trace file in each SAP system. Therefore, only one SQL trace can be performed at a time. 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. D SQL traces are useful on the database server, but not on application servers, which yield inexact results due to network 49 times. PO Guide Chapter 4 When should you perform an ABAP trace? A If a problem occurs with the table buffer B For programs with high CPU requirements 50 C For I/O problems with hard disks PO Guide Chapter 4 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.

51

PO Guide Chapter 5 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. 52 PO Guide Chapter 5 How should you configure and monitor the dynamic user distribution? A By setting ths appropriate SAP profile parameter - for example, rdisp/wp_no_dia. B By using Transaction SMO4, User Overview 53 C By using Transaction SMLG, Maintain Logon Groups PO Guide Chapter 6&7 is a high roll wait time? What A A unique index for a GUI communication problem, for example, in the network between the presentation server and the application server. B A unique index for an RFC communication problem with SAP or non-SAP systems. C A unique index for a GUI or RFC communication problem. D A problem caused by an ineffective network between the application and the database level. 54 PO Guide Chapter 6&7 transaction step, a transaction is processed and controls In a are used, but no external RFC is called. Which of the following statements are correct? A The GUI time is greater than the roll wait time. B The RFC time is greater than the roll wait time. C The roll wait time is always greater than zero D The roll wait time is normally greater than zero, although it can also be zero. 55 E The roll wait time is always zero. PO Guide Chapter 6&7 transaction step, a program that uses no controls and no In a synchronous RFCs is processed, although asynchronous RFCs are called. Which of the following statements are correct? A The GUI time is greater than the roll wait time. B The RFC time is greater than the roll wait time. C The roll wait time is always greater than zero D The roll wait time is normally greater than zero, although it can also be zero. E The roll wait time is always zero.

56

PO Guide Chapter 6&7 application that uses ITS and an SAP system is running A web "too slowly". What analyses do you perform? 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 57 time. PO Guide Chapter 8 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 58 memory. PO Guide Chapter 8 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.

PO Guide Chapter 9 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. 60 C The table is changed often. PO Guide Chapter 9 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 61 synchronously after a database change operation. PO Guide Chapter 10 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. 62 PO Guide Chapter 10 Which of the following statements are correct to the ATP server ? A The ATP server should always be configured on the tabase server. B The ATP server is an independent SAP installation with its own database on the separate computer. C The ATP server reduces the number of accesses to tables 63 RESB and VBBE .

PO Guide Chapter 10 When buffering number range objects in main memory, which of the following considerations should you keep in mind ? A) SInce buffering occurs in all SAP instances, buffer synchronization may cause some numbers to be assigned twice. 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. D Sufficient physical memory must be available, because number range buffering consume a good deal of memory 64 PO Guide Chapter 11 Which of the following statements is correct with regard to expensive SQL statements ? A) they can lead to hardware bootlenecks (a.CPU or I/O bootleneck ) and negatively affect the runtime of other SQL statements B) 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. C) they can occupy a lot of space in the SAP table buffer and displace objects which causes unnecessary relaod operations 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. E) expensive SQL statements in programs for reporting or in background programs are not normally a problem for the database. 65 PO Guide Chapter 11 the results of an SQL trace, you find an SQL statement that In has a runtime of 1 second and selects only 10 records. Which of the following could be reason for the long runtime ? A) There is a hardware bootleneck (a CPU or I/O bottleneck ) on the database server. b ) There is a network problem between the application erver and the database sever. c ) the database optimizaer has created am inefficient execution plan - for example, by choosing an inefficient index . d ) there is no approporiate index for the SQL statement e ) there are 66 exclusive locks waits in the database.

PO Guide Chapter 11 the Shared SQL Area Monitor, you find an SQL statement In with 10,000 logical read accesses per execution ( indicated as Gets/?Execution ). Which of the following could be the reason for this high number of read accesses ? A There is a hardware bottleneck ( a CPU or I/O bottleneck ) on the database server . B TThere is a network problem between the application server and the database server . 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. E There are exclusinve lock waits in the database F A large number of records are being transferred from the database to the ABAP program . 67 68 69 PO Guide Chapter 10 When buffering number range objects in main memory, which of the following considerations should you keep in mind ? A) SInce buffering occurs in all SAP instances, buffer synchronization may cause some numbers to be assigned twice. B) Gaps occur on the number assignment when using buffered number ranges.

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.

0 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.

0 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.

0 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.

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.

0 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.

0 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.

0 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.

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.

0 A) they can lead to hardware bootlenecks (a.CPU or I/O bootleneck ) and negatively affect the runtime of other SQL statements B) 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.
