Is it possible to stop backfilling (violently interrupt) in AF Analytics?

Hi,
I can not find specified, can you explain in more detail?
Thanks,
Igor
Hi Igor,
As Lal mentioned, All the recalculation initiated will be stored in an XML file under "%ProgramData%OSIsoft\PIAnalysisNotifications/RecalculationProcessor.RequestedRecalculations.xml".
You can remove/Rename the file making the Analysis server to think the file is corrupted or not available hence it will create a new one for storing the re-calculation details.
In order to stop the existing queue, we can stop the Analysis server from your service list and rename this file or move it to different location. Now if you start the Analysis service, it will create a new file.
This is a work around to interrupt the re-calculation.
Thanks,
Shibu
Hi Igor,
Out of curiosity, why do you need to terminate the recalculation processor?
Thanks,

Hi Sebastian,
I started some recalculation, and I see that it would take two days.
I will not interrupt.
Hi Igor,
I can see that the time span for the recalculation request is 3 months. Was this on a single analysis or multiple analyses? Terminating the backfill\recalcuation operation as Lal and Shibumon suggested is fine. What you can do to avoid such a long time for backfilling\recalculation is to break down the process into smaller time span and\or perform the backfilling\recalcuation on a smaller set of analyses.
If this is on a single analysis, could you share the configuration?
Can you share your analysis service configuration and version? We may be able to fine tune it to increase the performance. You can get the configuration from PSE, on the management tab, under operations in the right pane, right click > "Edit Analysis Service Configuration".
Thanks,
Seb
Can you also share the configuration of the analysis?
Thanks,
Seb
Hi Igor
Only option is to terminate Recalculator process and remove xml file from %programdata%OSIsoft-->AFAnalysisNotifications*(RecalculationPRocessor).
Thanks,
