Running an application under 64Bit JVM
Hi - I've a 3rd party application that we've deployed and operated in a 32Bit JVM.
We're looking to move to a 64Bit JVM primarily because our hardware platform / OS / App Server mix mandates the use of 64Bit JVM.
If I deploy the 3rd party application into a 64Bit JVM are there any gotchas I need to consider - performance or otherwise? I realise there's probably an increased GC overhead given larger heap space etc etc.....anything else?
Is it safe to assume that functionally the application will continue to operate as before and that I only need to focus on tuning the JVM for optimal performance??
