Diagnostics: Cumulative SQL Trace (DB2 UDB for UNIX and Windows) 

This function is not available for systems monitored using a remote database connection..

You can access trace information on SQL statements by calling the DBA Cockpit and choosing Diagnostics  ® Cumulative SQL Trace in the navigation frame of the DBA Cockpit. The Diagnostics: Cumulative SQL Trace screen appears.

If you want to retrieve new data, choose Refresh.

The following information is displayed on the EXECUTE, PREPARE and FETCH times of SQL statements:

Column	Description
Total Time	Cumulative execution time of a statement
%	Proportional execution time of one statement with regard to all executed statements
Count	Number of executions
Time/Stmt	Average execution time of one statement
Table	Name of the table the SQL statements reads from. If the statement reads from more than one table, only the name of the first table will be displayed on this screen. The other names are displayed under Statement Information on the detail screen.
SQL Statement	Complete SQL statement

If you want to display more detailed information, double click a line or select a line and choose Details. The Cumulative SQL Trace ‑ Details screen appears providing information on:

·        Statement Information

Displays the complete SQL statement, the application server where the statement was executed and a list of all ABAP reports in which the statement can be found.

·        Time Histograms

Displays the distribution times of the selected SQL statement.

If you want to display the access plan for the execution of a single statement, select a line and choose Explain. This function provides a detailed analysis of expensive SQL statements. For more information, see The EXPLAIN Function.

To display the ABAP source program where the statement was defined, choose one entry in the list of ABAP reports. An editor screen appears, which contains the related source.

Since all trace data remains permanently in the database, you should delete obsolete data before starting a new trace. To do this, choose Delete on the Diagnostics: Cumulative SQL Trace screen.
