How to force Qlik to get rid of data in memory

[renovero]

Hello,

In our QlikView Server there is an option (but i don't know where) to Qlik to empty some of old data in memory modules. It is turning on automatically, when there is not enough of RAM, and I am reloading something.

The questions are

- where is the option, when and how much of Ram can Qlik handle before empty them?
- Is there any way to force that behaviour? For example, I need to reload app stored in memory but first I want to get rid of some older data, or maybe that app in memory, to give space ton new, actual version.
- As I saw, this behaviour is not 100% correct, there are times, when I am kicked out from Remote Desktop because the use of RAM is 100% and Qlik didn't start to place some data in trash.

I will be glad for answers 🙂

Hi @renovero 

The following articles describe how the Memory is managed:

Qlik View server is running on high memory usage

Hope it helps.

Hi,

In order to free memory, you could reduce the document timeout of your QlikView server, but then the user experience might not be that good as the first user might need to wait a bit till the document is loaded again.

Another option you might use is the one described in:

I hope this helps you!
