z/VM performs such magic in at least three different ways: Discontiguous Saved Segments, Named Saved Systems, and VM Data Spaces. These mechanisms are probably somewhat relevant to z/OS when it operates as a z/VM guest.
I hate to disagree with Jim Mulder. :-) But I'm going to disagree with his absolute "No." Specifically and as an example, Java on z/OS does some interesting things with shared memory that, in my view, fit the question as stated. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, zEnterprise Industry Solutions, AP/GCG/MEA -------------------------------------------------------------------------------------------------------- E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
