Performance Analysis(ST05) :
This tool contains SQL Trace, Enqueue Trace, RFC Trace, Buffer Trace. SQL Trace displays the details of database tables accessed as part of the program/transaction execution. It contains the details of how the OPEN SQL statements are converted to standard SQL statements,positions of COMMIT statements,repeated database accesses,what database accesses or changes occur in the update section of application. Enqueue Trace helps you to track the locking and unlocking statements with details like Table names of lock event,name of the program that set the lock,type of lock,total time required for the lock. RFC Trace allows you to track the RFC calls that are triggered upon executing your application.It provides the details of function modules that have been called remotely,total time used to process the remote call,whether RFC was executed successfully,number of bytes sent and received etc. Buffer Trace allows you to monitor the table buffer accesses with details of table name,buffer type,key field values of buffer access. Runtime Analysis( SE30 / SAT ) :
This tool is required to calculate or evaluate the quality of the code.This measures the CPU time required by ABAP statements like Database access (Open SQL,Native SQL statements,IMPORT,EXPORT....) Modularization Units(PERFORM,CALL FUNCTION,CALL METHOD,SUBMIT,CALL TRANSACTION...) Internal table operations(APPEND,COLLECT,INSERT,MODIFY,READ TABLE,SORT...) Data Transfer(READ DATASET,TRANSFER.....). Measurement Options Overview : The Evaluation Overview contains total runtime required for(as a bar chart): ABAP interpreter Database System statements For ABAP and System statements : Red bar indicates that the category required more than 50% of total run time. Green bar indicates that the category required less than 50% of total run time. For Database operations,red bar appears if category required more than 25% of total run time. Other available options are Statement Hit list,Table Hit list,Group Hit List,Call Hierarchy etc. |
