As these instructions are often folks who are just starting out to evaluate Ops Manager, it's important to leave a great first impression. Therefore, we should include instructions on how to set the required ulimits as part of this tutorial.

Yes, we should have someone from the Ops Manager team confirm the instructions.

I don’t think those will work directly - a reboot would probably be needed.
I think that there’s probably a way to do it with sysctl without a reboot.
Could you join #private-cloud-om, and the on-call person should be able to help test it out?

Hi Corry,

The user is instructed to use RHEL 8, but we provided ulimit instructions for RHEL 6 (see attachment), which are not applicable to RHEL 8. 

I simply added added the following to /etc/security/limits.conf:

* soft nofile 64000
* hard nofile 64000

But it's probably worth getting someone from Ops Manager engineering to confirm that's the recommended approach. That's just what I (an SA) did to get it to work .

Regards,
Brian
