The default benefit is one particular second of life time for each absolutely free megabyte while in the heap. The -XX:SoftRefLRUPolicyMSPerMB solution accepts integer values symbolizing milliseconds for every a single megabyte of the present heap sizing (for Java HotSpot Customer VM) or the utmost possible heap dimensions (for Java HotSpot Server VM).
The results of the response could be available to the faculty from the question established. Further more the result would even be mailed to the scholar.
If adaptive sizing is disabled (using the -XX:-UseAdaptiveSizePolicy possibility), then the -XX:SurvivorRatio solution need to be used to set the size on the survivor Room for the whole execution of the appliance.
