The only reason I know is because *nix processes don't share memory but z/OS Unix processes coexist in an address space unless specifically requested. Each *nix process has a page table with page table levels. It's unclear but these levels seem to be *nix answer to z/OS subpools but then again, maybe they don't. The newer *nix hardware seems to have 6 levels to allow larger address spaces. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
