I installed Linux FC6 64-bit on the machine DELL 2590(I think it is INTEL type CPU). But JVM 64-bit is only available for AMD and SPARC. Is the SUN not support INTEL? Thanks, Dave

On 32 bits linux, it's about 2G (that is 4G minus memory area reserved for kernel, minus memory area used by libraries minus other thingies jvm might use). To get more you will need a 64bits JVM + a 64 bits OS. Note it's a limitation of hardware architecture and OS more than a limitation of JVM. PS: if you plan to swap-out 12G of datas, i hope your disks are fast :) -- http://www.devlog.be (a belgian developer's logs) --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------- Never miss a thing.
