Do you mean the hard limit for a 64-bit JVM or the hard limit for RHEL? The 64-bit JVM accepts a long value for max heap size, so look up Long.MAX_VALUE. According to this page, RHEL running on a 64-bit Intel chip (not Itanium) accepts 1TB or RAM. http://support.bull.com/ols/product/system/linux/redhat/help/kbf/g/inst/PrKB11417 http://support.bull.com/ols/product/system/linux/redhat/help/kbf/g/inst/PrKB11417 Of course, this is absolutely useless information (unless you have a motherboard than has enough memory slots for 1TB) - your pratical limit is the amount of RAM you have. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/744545#744545] Start a new discussion in Performance Tuning at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2078]
