7.7 Determining the handling of objects that exist for a fixed time period in Java heap
The explanation in the previous sections is based on the assumptions that the objects are to be saved in the following way in their respective areas, depending on the lifespan of the objects:
-
Save the objects with a long lifespan that are necessary for the operations of the applications in the Tenured area.
-
Save the objects with a short lifespan that are used for the request and response processing in the New area.
However, there are objects used for a fixed time period with an intermediate lifespan. Although such objects do not have a long lifespan, copy GC is executed a number of times for them.
When estimating the memory size, you must estimate assuming that these objects are to be stored either in the New area or the Tenured area.
The respective features are shown below. Depending on the type of the application and the purpose, estimate which memory size is to be increased.
