Engines for genius
If windows server has a limitation of 9 engines...
Why QMC lets us configure unlimited number of engines?

There is a windows configuration available from support -- and here on the forums -- that provides for greater than 9 engines.

Do you have this link to the forum? My server has 48 cores and 256Gb, and I can run just 9 concurrent engines. I 'm wasting server.
Thanks

Thanks Bill, this configuration is sufficient to put for example 48 concurrent engines ?
Or these parameters are proportional?

It is something you will have to play with. I don't think running 48 concurrent engines would be a good ideal. You have to look at the memory that is used by each task and then save resources for the OS and QVS.

Hi
As I now ,distribution service himself is controling quanttity of paralel reloads (by setting in QMC). For example if you start 40 tasks at one time but setting is 9 - at same time will be working only 9 but all 40 tasks will be done.
And these 9 tasks will use significiant resources anyway.
Am I true, experts ?
Best regards

Hi,
I have the same problem too.
I'm using 24 cores, 64 bits, 64GB memo.
Initially i set "Max number of simultaneous QlikView engines for distribution:" to 15 in QDS.
and now i set it to 24-1 = 23. still the same result.
What are the risks of changing the heap registry?
Any other way of doing it?
