Compatibility with Z/OS 1.7

  • 1.  Compatibility with Z/OS 1.7

    Posted 12-22-2005 10:20 AM
    Hi all,

    I am working with a client who is still using IDMS Release 14.1; they are
    aware that CA has dropped support. Their systems people plan to upgrade
    from z/OS 1.4 to z/OS 1.7, and the timing, of course, coincides will the
    release of another system - of a critical nature.

    I have been asked to find any information that I can regarding the
    compatibility of IDMS 14.1 with z/OS 1.7. I'd greatly appreciate any
    information that you can share.

    While it is my client's hope that it has been others' experiences that 14.1
    and z/OS 1.7 does not have any compatibility issues, I also would
    appreciate any feedback how ""easy"" the upgrade from 14.1 to 15.0 is. When
    the client contacted CA regarding the compatibility issue, they were
    referred to Support and told there was no information available. Also the
    manager stated:
    ""I have heard that it's very easy to upgrade to 15.0 from 14.1, so
    you may
    have to do that.""

    Thanks for your help.

    Re: Compatibility with Z/OS 1.7
    "Cindy,

    There is an apar, QO60139, that deals with z/OS 1.6 console problems for
    14.1 you may want to apply. Going from 14.1 SP6 to 15.0 SP4 here was a
    piece of cake. I did an upgrade install and only had some problems with
    CICS interfaces. The rest was pretty much (simple eh?) just put the 15.0
    load library 1st. If you need anymore details let me know.

    HTH,

    Re: Coding Allowing in ADS to check for 0966
    "Chris,

    The only way to do this is using a DC-COCOL program. I can dig up an
    example if you need but it just readys each area and checks the error
    status. You can not do this in ADS code.

    Re: PAGE RESERVE AND CALC ALGORITHM
    "Usually don't reply, but am bored today

    Page reserve for calc records, not a good idea. Why? Your calc
    algorithm and your number of pages should be such that there is (more or
    less) an even fill factor across all pages. If you have a lot of calcs
    going to the same page, then maybe you need to pick a better number of
    pages (does prime+1 still make a difference?) or fix up the calc key to
    be more random (there are a number of ways to do that)

    So lets say you have 100 records, and 10 pages, and each page can hold
    15 pages.

    So let's say that the number of records per page after the load is
    something like this (x-y where x is the page number and y is the number
    of recs)
    1-10 2-9 3-12 4-12 5-13 6-8 7-11 8-10 9-7 10-10
    Now let's say that you pick a max of 10 records per page for you page
    reserve thing - so now what you have is
    1-10 2-9 3-11 4-11 5-11 6-11 7-11 8-11 9-7 10-10

    A lot more even with room on each page - except that 1 of the calcs for
    page 3 is on page 6, one of the calcs for page 4 is on page 6, one of
    the calcs for page 5 is on page 6 and another one is on page 8. (and
    exactly how they get spread around would really depend on how they were
    loaded and could be more convoluted then this, but I think you might get
    the idea)

    So although you might have accomplished leaving more room on each page,
    you haven't helped the calc situation at all, and even at the start, you
    have unnecessary calc overflow situations.

    If you run out of space with a calc area you could use an expand page
    first. If that is not possible, then extending would work, but the
    extended portion would only be used for overflow and no calc records
    would 'calc' to those pages. When you extend, if done correctly, there
    is no change in the calc algorithm - if there is, you did something
    wrong and will be in major big trouble.

    As an aside, you can check out your fill factor prior to loading by
    using idmscalc and some quick programming - obviously depends on the
    number of records, pages, etc. as to what is involved

    PAGE RESERVE AND CALC ALGORITHM
    "Hi everybody !!!!

    We are trying to unload/reload a page with calc records and defining a page
    reserve for the future new records. Is there any effect in the calc
    algorithm with the page reserve sentence in the area ??? I remember than in
    the past I had some problems extending a page with calc records, because the
    clac algorithm consider the page range and if you extend the page range
    there is a change in the calc algorithm. I'm wonder if in the case of page
    reserve is there any effect in the calc algorithm ?? The idea is
    unload/reload one area using page reserve of *** characters and after that
    switch the page reserve to 0 characters.

    TIA.

    Javier S.

    Re: Compatibility with Z/OS 1.7
    "Also, there is a problem with DMLO under 16.2 that CA is working on. It is
    a nuisance issue only. If you go into DMLO and put in a dbkey,without any
    previous dml activity, you will get an error message. CA is working on the
    solution.

    16.2 is a better release that 15.0 from what we have seen. We are going to
    upgrade the one client we have from 15.0 since we have had a number of
    issues with it.

    Cindy, I am just catching up on e-mail after vacation so please
    forgive the delay in responding.

    I can't comment on Z/OS 1.7 but I can say that the upgrade from R14.1
    SP5 to IDMS R16.2 was a snap. R16.3 is out now and should be a similar
    upgrade. If you can convince folks to skip R15.0, R16.3 would seem to
    make better sense since it will be supported long after R15.x is
    dropped.
