Out of Object Memory

Hi All,

Whenever i reload any applications it is displaying out of object memory. Is there any specific reason for this error. Even some times when i do any update for any of the charts it is displaying like allocation memory exceeded. Any help would be appreciated. Thanks In Advance. Suresh.

Re: Out of Object Memory

Usually happens because of large data volumes or not enough resources on the machine. 

Try making some selections and see if it can render the chart.  Also make sure you have no loops or other issues in the data structure.

Unfortunately if you are talking about hundreds of millions of rows of data Qlikview is not great at dealing with that without using some kind of additonal aggregation (IE drop granularity or summarise data in script by grouping it), or altrnatively throw more hardware at the problem.

I have seen Qlikview applications running hundreds of millions of rows with all detail but you require some pretty heavy server hardware to deal with this.  The site where I saw it had 4 clustered servers with 256GB RAM each and at least 16 core Xeon CPUs...
