Performance: 2.8 Alpha running out of memory?

March 13, 2013 6:04AM

Hi all - Yesterday we installed 2.8 on our server (20GB RAM). We are used to process big data files (up to 60 million rows) whithout any problem in 2.7. When using 2.8 even files with 1,3 million rows are not loaded into DataManager as Omniscope is running out of memory. In Windows Task Manager, we see that that Omniscope instance is not using more than 1 GB of RAM.

My first idea was that this had to do with maximum settings in "instal.properties" or "wrapper.config". After enabling and adjusting the maximum memory values in these 2 files, the performance of 2.8 did not increase.

Please advise us on what to do? Thanks in advance!

Regards, Alexander

Hi Alexander,

Please have a look here how to configure RAM: http://www.visokio.com/kb/omniscope-memory-allocation

If you are using Windows service to run the Scheduler, please set up
wrapper.java.maxmemory parameter in wrapper.conf (default-wrapper.conf).

If you are running it as a process, set up MAX_MEMORY_MB in installconfig.properties.

If you are using your own command files, please set up -Xmx parameter.

If it doesn't help, please describe how you are running the Scheduler and email me the config files: wrapper.conf (default-wrapper.conf), installconfig.properties.

Hi Alexander,
If you are using the Scheduler, check the same operation in Omniscope and see if memory usage increases.
Are there any other processes running using all the memory?
Have you changed the Priority of the Omniscope Java process to low priority in Task Manager?

Regards, Mohamed

Welcome!
