Re: I/O Overhead - z/VM versus VMWARE

2008-11-02 Thread O'Brien, Dennis L
Alan, http://www-03.ibm.com/systems/resources/systems_z_news_announcement_pdf_ zvm.pdf has a discussion of z/VM vs. VMWARE in Appendix B. I've seen a link to an entire white paper devoted to a comparison of the two. I thought it was on IBM's site, but a quick search didn't find it.

z/VM data areas, control blocks, and monitor records

2008-11-02 Thread Alain Benveniste
We have no easy from work to consult z/VM data areas, control blocks, and monitor records through the web. I wonder if their is a book where all of this is documented. I took a loo k in the CDs, not found. Or is their a way to download through the web ? Alain

COPY HCPXCTBK

2008-11-02 Thread Shimon Lebowitz
I have a CP exit which has run for years, and I see in the code that I put a COPY HCPXCTBK statement. I can find no reference anywhere to why I should need this line (except that it appears once in a sample). Does anyone else have it? May I ask what for? Can I leave it out? Thanks! Shimon

If you want something more immediate, you can code a process in PROP (or any of the other console managers). (i.e. look for LINUX70 LOGGED OFF and execute a XAUTOLOG) My PROP includes a routine called RELOG which keeps a list of 'important' virtual machines, to be automatically logged on

I'm not even sure how they would wind up on a comparison, but roughly, if you need high I/O or transactional capabilty -- use z/VM. If you need a whale of a lot of CPU processing, use Intel. On Nov 2, 2008, at 9:34 AM, Barton Robinson wrote: Exactly, but the issue is to explain this to

Sure- and it does a good job doing that too. On Intel x86. That's what confuses me- the two platforms, mainframe and x86 are hardly competitive to each other. Or perhaps they are in some minds. But something sure had to go down twisted to get that kind of comparison running again. :)
