AB Suite MCP provides the ability to capture report performance statistics for all methods invoked by the report that are Class, Segment and External Class (Library). This might be beneficial when tuning reports for optimum runtime performance or identifying poor performing methods.

When this feature is enabled (see “To enable report invoked method runtime statistics”) there will, naturally, be a slight runtime performance penalty associated with the statistics capture. For this reason, we do not recommend running reports with the method statistics enabled in a production environment unless it is for isolated or specific cases where the same testing cannot be achieved in a test environment.

To enable report invoked method runtime statistics:

Modify the existing Taskstring associated with the NGENxxSYS/BLD utility to include SETMETHODS.

All reports generated while the SETMETHODS is present in the BLD taskstring will have the invoked method capture enabled.

The Generate log will inform you if the report method statistics are enabled for the report deployment and a display to the same affect is shown during report execution.

Example

Report Deployment:

26/03/17 @ 23:32:06 Report Compiles Started (Server Id 420-8886) [1-J 8431]

26/03/17 @ 23:32:06 Warning: Method Statistics Enabled

26/03/17 @ 23:32:08 Total Units to Compile 3

26/03/17 @ 23:32:08 Report Units Compiled (DMA) 1(33% Complete)

Report Execution:

23:32:33 8447 MSRDISP14:DISPLAY:** Method Statistics Enabled in CUSTLIST **.

The report methods statistics are written to a CSV file called <system>/<report>/TIMINGS/<report mix #>.

This file name is also displayed by the report prior to EOJ.

Example

23:32:33 8447 MSRDISP14:DISPLAY:Timing Summary: SAMPLEBLOB/CUSTLIST/TIMINGS/08447.

The statistics provided are:

This will include statistics for all invoked class, segment and external class (Library) methods. External Class methods are identified by a method name suffix of ‘(L)’.
