G1GC still has an Eden size, however, it's strongly recommended *NOT* to set the new gen size G1GC and just let it figure it out based on your target pause time. Thanks, Daniel On Sun, Oct 4, 2015 at 4:11 PM, Tushar Agrawal wrote: > If you are using CMS garbage

If you are using CMS garbage collector then you still have to set the HEAP_NEWSIZE. With G1GC (new recommended GC) there is no concept of New or Older generation. On Sun, Oct 4, 2015 at 5:30 PM, Kiran mk wrote: > Is HEAP_NEWSIZE configuration is no more useful from
