To know about the JVM bit version i.e. currently running on Linux Server, use following command: #java -d64 -version or #java -d32 -version If you have 32 bit JVM and you run above command i.e. java -d64 -version, then you'll get some error message on the console like .... [root@localhost default]$  java -d64 -version Running a 64-bit JVM is not supported on this platform. And if you run command "java -d32 -version" , then you'll get.... [root@localhost default]$  java -d32 -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode) !Hope this will help you !Enjoy Kuldeep Sharma
