Performance: Limiting max RAM usage per user account/instance?

stavro · December 12, 2014 7:39AM

Hi Everyone,

Is there any way to limit the RAM usage of an Omniscope report? For example, I want to set that every Omniscope report will use max 7 GB RAM. The number of opened files doesn't matter.

I am using Server Edition 2.9-beta b1342

Stavro - Yes, you can limit the maximum amount of RAM available to Omniscope by editing the installconfig.properties file to set the MAX_MEMORY_MB parameter, in your case to 7000. The KnowledgeBase contains directions for doing this:

May I ask why you want to set the limit? Is it because other applications running on the same machine need allocated RAM?

On this Server 6-7 persons open reports and they spend a lot of RAM. As a result, some reports are closing unexpectedly.

In this way every report will use max 7 GB ram is it true?

Yes, each instance of Java/Omniscope should use maximum 7 GB RAM...but if you have multiple accounts/logins on the machine the total concurrent usage across multiple instances will be higher. I assume the 7 GB limit divides available RAM across all the user accounts/logins that might access the machine concurrently?

Welcome!
