As a quick note, I saw the PrintFlagsFinal
Java/JVM option today, and thought it was interesting. I saw this command:
java -XX:+PrintFlagsFinal -Xmx64m -Xms32m -version 2>&1 | grep -i -E 'heapsize|permsize|version'
which yielded this output:
uintx AdaptivePermSizeWeight = 20 {product} uintx ErgoHeapSizeLimit = 0 {product} uintx InitialHeapSize := 66328448 {product} uintx LargePageHeapSizeThreshold = 134217728 {product} uintx MaxHeapSize := 1063256064 {product} uintx MaxPermSize = 67108864 {pd product} uintx PermSize = 16777216 {pd product} java version "1.6.0_24"
Of course the grep
part is optional; try the java
command without the grep
to see all of the output.
I found this command on this SO link.
