The playback simulation can be useful for checking that you have enough bots defined for the playback, as well as enough background processes defined on the playback system.
To run the simulation, go to Execution —> Execution Queues, select your execution queue and click on the Simulation Playback button:
On the selection screen, enter the following information:
- No. of worker jobs: set this to the number of bots you currently have
- No. of available BGD processes: set this to the number of background processes defined on the playback system
- Time frame: if you would like the simulation broken down into time slices, select one of the radio buttons
- Enable midnight boundary: if your recording crossed a midnight boundary, then select this checkbox
When you execute the program, you will be presented with the following output. (Note that for large execution queues it can take some time for this program to run. You may want to run it in background and view the results from the spool.)
There are two key metrics to consider on this report:
- Max. active batch jobs in target system: if the number shown is equal to the number of available BGD processes you specified on the selection screen, then you could potentially speed up the playback by adding more BGD processes on the playback system.
- Max. concurrent SAPGUI users: if this number is greater than twenty times the number of bots you have, then you may well need to add more bots in order to speed up the playback.
