Analyzing Data with HP SPT/XL The data collected by HP SPT/XL is stored in logfiles. The HP SPT/XL Analysis Software reports the performance data in these logfiles. Information on the following is available online: * Intrinsics * Files used * TurboIMAGE databases used * Program code and executing library code * Transactions HP SPT/XL bases its analysis on a unit of work called a transaction. To HP SPT/XL, a transaction begins with a program call to an intrinsic. A simple, but common, example would be a transaction that begins with an FREAD from a terminal. There is an extensive list of intrinsics that HP SPT/XL recognizes as possibly delimiting transactions. You can define and redefine these transactions as you analyze your application with HP SPT/XL's Analysis Software. Prior to collecting data you may decide to modify your application source code to include the STARTTRAN/ENDTRAN intrinsics which will delimit logical transactions within your application. See appendix B for details on these intrinsics. For information on HP SPT/XL's Analysis Software see the HP SPT/XL User's Manual: Analysis Software.
