I am trying to run Oracle RAC in Docker Containers. As a requirement I need to enable Real Time Kernel.
Starting the docker container with:
–cpu-rt-runtime=95000 --ulimit rtprio=99
Error response from daemon: Your kernel does not support CPU real-time scheduler
There is no RT Kernel in Ubuntu. Instead I have installed the low latency kernel.
Ubuntu is stating about the low latency kernel the following:
and also these series:
Basically they’re saying that the low latency kernel is almost as good as the real time kernel.
So, does this mean that I might simply ignore the requirements for RT and go with low latency?
Or maybe someone knows a simple way to install a RT kernel in Ubuntu?
