Heap settings

#1

My servers have 188GB RAM. I initially set heap to 16GB

-Xms16g
-Xmx16g

Logs is showing:
[host04] heap size [15.8gb], compressed ordinary object pointers [true]

and

Heap address: 0x0000000400000000, size: 16384 MB, Compressed Oops mode: Zero based, Oop shift amount: 3

Do i need to adjust heap to 30G?

You most likely can increase your heap somewhere near 30GB for the exact value follow the instructions in the doc referenced above.
