Nprinting Limit resources usage ?

glacoste — Thu, 08 Mar 2018 21:01:05 GMT

Dear community,

I have a problem with the usage of resources (memory and cpu) from nprinting server, in my case i use nprinting server in the same machine of qlikview server(I know it's not ideal, but this problem would happen anyway if they were different machines). So, when nprinting is running in sometime use 4 qlikview desktop process for extract the data and this use toomuch memory and cpu.

Exist a config file in NPrinting like to qlikview server for cpu usage limit and memory?

Hi,

Installing Qlik NPrinting Server in the same computer of QlikView Server is not supported. You must install them into two different computers.

Qlik NPrinting Server uses all the hardware resources of the computer where it is installed.

QlikView Desktop processes are opened by Qlik NPrinting Engines. So I suppose you installed the Engine on the same computer as the server and this is supported. Qlik NPrinting Engine opens at least one QlikView Desktop process (Qv.exe in the task manager) for each QlikView document used to create reports. Qlik NPrinting Engine is multitask so it could open many Qv.exe processes to open the same document multiple time to maximise performances. After finishing report creation a Qv.exe process for each document could remain opened to have a faster report generation when the Qlik NPrinting Server ask for new reports from the opened document.

Best Regards,

Ruggero

Thanks for reply rpc‌

I think not provide a way for limit the resource usage in NPrinting it is simply a bad design decision. Even you use a dedicated server for run NPrinting engine, the system need free resources for run important process as remote desktop, antivirus and another critical tasks.

So this type of behavior as you describe should be configurable.

If you install Qlik NPrinting in the supported configuration you will not have issues about resources for other tasks like remote desktop or antiviruses.

Ok, I request a new server only for NPrinting. Can you tell me the requirements of the machine for install (NPrintin Server+NPrinting Engine) in the same machine?.

btw - keep in mind that to optimize resource usage you should use qvp (server) connection. Local connection will always hit the roof (sooner or later)
