| InitiatingHeapOccupancyPercent | int | The percent occupancy (IHOP) of the current old generation capacity above which a concurrent mark cycle will be initiated Its value may change over time if adaptive IHOP is enabled, otherwise the value remains constant. In the latter case a value of 0 will result as frequent as possible concurrent marking cycles. A value of 100 disables concurrent marking. Fragmentation waste in the old generation is not considered free space in this calculation. (G1 collector only) |
