OCI 7.3 Memory Usage OCI Server

[sstrznwra]

Hi,

Has anyone experience with OCI 7.3 SP1, we see on our OCI Server high Memory usage. UI Memory usage is High Health 92% 

That goes so far that the server no longer reacts and we can`t restart the sanscreen server service , only a Server reboot is possible.

After approximately 2 Days run time from the Server the same problem comes again.

We use:

VM Windows Server 2008 R2 Standard SP1

32 GB Memory

8 Cores

44 Data Sources

Thanks

Hi Michael,

It's probably worth opening a case with support here. You'll want to look at the basic server sizing (v7.3 uses more memory the v7.2, so you may need to up the resource in the server / VM), which specific service (ie server, acq, elastic, mysql) is growing memory usage over time, as well as whether any of those processes are approaching the memory limits configured in the -xmx parameters in the registry.

I have seen other cases where tweaking the config to allocate more memory to the acq service ends up reducing the memory usage of elastic quite considerably, but I can't really say for sure whether that would fix your issue here.

Regards,

Bryan

Hey Michael,

It is a bit surprising that you would see memory utilization change as a result of a data source service pack - most of the memory OCI uses is controlled by registry / configuration file settings that are populated when you install OCI (this is why increasing memory on an OCI server may not have a major effect, as the OCI services will not get a lot of benefit from them). Because of the software stack OCI uses internally (Java, MySQL), memory management is a bit tricky - the OCI Installer attempts to set configuration settings to allow OCI to use as much memory as possible without causing any problems.

'

In general, however, OCI 7.3.0 needs more memory than earlier OCI versions. It may be that your environment needs > 32GB.

If your OCI server is sending OCI ASUP, PM me the site name, and I may be able to offer some suggestions

Hey Matt, Bryan

Thanks for your reply.

I opened a Case 2006947392 yesterday, and support told me for our envirnonment we must expand to

Memory GB 48

Cores 16

Disk 1241 GB

there is not a problem to expand this,not so nice is that we must reinstall OCI that the software validate the change.

#Matt: We saw this behavior even before SP1 

Thanks

Michael
