docker-images: Oracle 19c does not start because of memory configuration

Hi,

I try to use Oracle 19c Docker image built using provided in this repository steps. The image is built correctly - works on my machine very well. But when I tried to run it on our Jenkins machine, I could not start it. I can find the following errors in Docker logs:

I couldn’t find any information how to configure this memory. Any hints?
