Thanks for your response Per. I can confirm it's dynamically. We increased our resources and the heapsize increased for our tomcat.
When we want to increase the heap_size with the size of our environment variable. Where do I have to set this? Inside the tomcat container or on our openshift-master or... ?

The heap allocation is done dynamically. When the image starts it runs /opt/webserver/bin/launch.sh. In this file you will find MAX_HEAP=`get_heap_size` if [ -n "$MAX_HEAP" ]; then CATALINA_OPTS="$CATALINA_OPTS -Xms${MAX_HEAP}m -Xmx${MAX_HEAP}m" fi The function "get_heap_size" is sourced from /usr/local/dynamic-resources/dynamic_resources.sh. What I *think* it does is checking if any resource quotas are set, and if so allocates 50% of the available memory as heap. The percentage can be changed by setting the environment variable CONTAINER_HEAP_PERCENT to e.g 0.10 (to get 10%).

It's different on our servers than on our local machines. What's the best way to set this parameter?
