Hi Team,
Is it possible to go for higher version of JDK(64 bit) and Tomcat(64bit) on
32 bit window 2003 architecture.
No.
A tiny bit more detail:
64-bit software requires a 64-bit operating system. A 64-bit operating
system requires a 64-bit CPU.
You're running 32-bit Windows, so you can't run any 64-bit software,
even if the hardware is actually 64-bit.
32-bit programs on Windows, including Java, are limited to addressing
2GB of memory. Which typically means that if you make the heap larger
than about 1.5 GB on a 32-bit system, Java's probably going to either
crash or not work correctly. This can be a serious limitation with
modern software.
Intel hasn't mass-produced 32-bit server-class CPUs since 2005, and
desktop-class CPUs since 2006. Other CPU manufacturers like AMD
probably did something similar around the same timeframe. Which means
that if your hardware is at all recent, it probably has a 64-bit CPU.
Thanks,
Shawn
