QlikView Memory Utilisation

Hi All,

We recently embarked on a project to MOVE our BI Application to a new Data Centre. Internally within our company there are some discussions going on about how much memory must be allocated to the new platform. Any ideas on the best Memory Allocation based on below, would be very helpful.

Old Platform

In the old platform we were using QlikView 10.0

There was no QlikView Publisher

Only one server was used

This was a physical blade server

Collective QVD size is ~150GB

Collective QVW size is 3GB

Memory utilization is average 80GB (Total allocated is 132GB)

New Platform

In the new platform we use QlikView 11.20

We are also using QlikView Publisher

Two servers. One to host QVS and QVWS and the other to host Publisher.

We are using Virtual Machines

If any more information is needed I'm happy to provide.

Many thanks in advance.

Hi Sheron, memory usage should be about the same as before, except that memory overhead when running tasks is now moved to a separate publisher.

What is the old environments Document Timeout setting? http://help.qlik.com/en-US/qlikview/12.0/Subsystems/QMC/Content/QMC_Documents_UserDocuments_Server_P...This is the setting that releases applications from memory (8hr default), by reducing this you can lower memory consumption a lot.

Hi Magnus, many thanks for your response. And that makes perfect sense to me.

I will find out the 'timeout setting parameter'

Hi Magnus,

We have indicated the timeout as 'blank' in the old environment

Sorry, you are in the wrong window. The setting should be under Settings QlikView Server, not under the document

No, It's under the Documents tab (same window).

Hi Magnus, changing the 480 minutes (8 hrs. from the time the document is published it will be available in memory) will reduce (300 minutes) or increase (720 minutes) memory usage.

Does the "Document timeout" correlates to Sessions? (Example: Maximum Inactive Session Time, Possible Session Timeout, Maximum Total Session Time)

If "Document Timeout" is set for 60 minutes, Possible Session Timeout, Maximum Inactive Secession Time should be set less than 60 minutes?
