    QVS server process memory useage

      Hi everyone,

       

      We have a dedicated QV server running version 10 of Qlikview, on windows 2003 with 32gb of RAM. Its also a 64bit environment as well. It does have 64gb of RAM installed and we are waiting on an OS upgrade to make full use of this extra RAM.

       

      The above enables up to 100+ users to use AccessPoint to view a QV document which is about 750mb in size. It is on a schedule to relaod each morning at 7am, with the QVD source files being sceduled to reload an hour earlier.

       

      Curently we are being forced to connect to the server and manage the QVS process. Having terminated teh process earlier today after the reloads (it was showing around 12gb memory useage in task manager) it is already back up to 7.5gb. We have to use the server for development due to local performance issues on desktop PC's which seems to contirbute further to increasing the QVS memory usage and it requires constant terminaton during the day.

       

      So, here is my question(s).

       

      Is there a way in the above environemnt to monitor by email, memory useage of this process and warn someone that it needs to be terminate?

       

      Is the above memory usegae normal for the above environment, and will the additional RAM give us more breathing space? (i.e. having a QVS process of 12gb+ is normal)

       

      Hope this gives enough information for some feedback, if not then please ask away.

          Hi,

           

          Had the same issue, and here is a simple way to automatically kill QV / QVS / QVB if using too much memory. QVS can be restarted by adding one more line "net start QVS" , wich does nothing if the process is running fine (meaning not not killed due to excessive memory )

           

          Recommend to set the threshhold around 95% of phisical memory for dedicated QVS servers. Of course, you need to study trends to find the valid memory limits for reload tasks (qvb.exe) and developer tool (qv.exe) in your environment .

              Hi Alex,

               

              Thanks for the reply and link to your blog. I have asked out IT team what they think to implementing something similar.

               

              Do you have any negative actions from terminating the process part way through any data loads or devlopment work?

               

              Many thanks

                  Hi,

                   

                  If there is one careless syntetic join over all available data , nothing works anymore . After that particular process is killed, loads / development / QVS work again.

                   

                  This kills only the offending proceses. Well, those scripts and files are not saved, or might get corrupted.
