Hi,

In JVM Diagnostics parameters like

-XX:-UseMarkandSweepGC
-XX:-UseParralelGC
-XX:-UseSerialGC
-XX:-HeapDumpOnOutOfMemoryError

options we are using [+/-] signs. what they are signifying here?

it seems + = Activate the option / -= deactivate the option

Is this is correct

Can some one provide light in this.

Yes you are right , minus (- ) means Deactivate (+) means Activate.

All the parameters you have mentioned is deactivated in this case.Java memory management is a good read.

Hope this helps.
