Definition

During operation of the VMC, there are a number of different memory areas for which separate garbage collections are performed.

  • All new objects are initially allocated to the young generation area. Once this is full, the area is cleaned by the garbage collector.
  • All objects that have been referenced for a longer period of time are moved to the old generation area. When the memory use reaches a certain defined point, a garbage collection is performed here too.
  • With the VMC, administration data and user data belonging to currently inactive users is stored in the shared memory like in ABAP. Garbage collections are also performed here when required.

This data element contains the number of times that the above-mentioned garbage collection has been called.
