Or you have to write an extension to allow processes to map parts of the larger space into their address space for use. This is what W2k and BSD/OS do (according to my google search :) Of course, once the extension is written then you have to modify the application to use it, which in the case of a close source DB vendor could be problematic. --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
