can anyone explain me how qlikview server use the memory when we have severals applications and many user .
Simple Senario :
i have one application with 8GO of size deployed on my server (96 RAM 6 cores ).beside i have 40 users who can acces this application .Let's imagine thats user 1 connect to server .How the mermory is used int his case ?
After deconnecting from the server how the mermory is used also in this case ?
in the case of many users in the same time .how it works ?
how works sign in sign out ?
RAM = (RAMuser × No. users) + RAMinitial
RAM〗initial = QVWsizedisk × FileSizeMultiplier; this is the initial RAM footprint for any application
RAM〗user =〖RAMinitial × userRAMratio; this is the RAM each incremental user consumes
QVWsizedisk = SourceData × (1 - CompressionRatio); this is the size, on disk, of a
userRAMratio: range between 1%–10%
FileSizeMultiplier: range between 2–10
CompressionRatio: range between 20%–90%
"For example: A 1GB .qvw document uses around 4GB in RAM for the first user (based on a multiplier of 4x to establish the initial RAM footprint based on file size). This multiplier is normally between 2x and 10x. User number two may increase this by around 10% as their calculations get cached resulting in a required RAM footprint of 4.4GB. User number 3 requires a further 10%, increasing the footprint to 4.8GB, and so on...."
i'v checked it out ,it's not released .
Are you sure about that ?
Because i'v seen on one of my last project , on the server it was required to have drain down's batch running on .
