Report types and interaction of time and... > General report and detailed report - Pg. 109

5.5 Report types and interaction of time and log options This section discusses the two modes of report generation and how time and log file options interact. 5.5.1 General report and detailed report When you execute the db2la command without the -D option, it creates the general report. For the DB2 RE GUI, this would correspond to the reports that are shown in Figure 5-5 on page 89 and Figure 5-6 on page 90. When you execute the db2la command with -D option it creates a detailed report. This corresponds to the running the report as shown in Figure 5-7 on page 90. The detailed report is based on the last general report that was run. Therefore, it is very important to run the general report with proper options first. DB2 RE GUI enforces the proper sequence. However, with db2la, you have to make sure that the general report is first run with the proper parameters. The detailed report is always based on the last general report. So, if you run a detailed report for parameters that are not covered by the general report, you will see unexpected results. For example, if you run a general report for time period T1 and then you run a detailed report for a different time period, T2, you will not see any transactions because the general report does not have transactions from the T2 time period and it ignores transactions from T1 time period.
