Installation of z/OS v3.1 using z/OSMF

  • 1.  Installation of z/OS v3.1 using z/OSMF

    Posted Tue October 24, 2023 12:52 PM

    Hi,

    We are in the process of installing the new z/OS v3.1 using z/OSMF,  but we are almost brand new doing it through z/OSMF. During this process, we expect things to change from the old Custompac dialogs, but not that much. There were many enhancement made through the years (CPAC), that hopefully were integrated into this new way of installing products. While going through the "Modify Datasets"could not find a way to CHANGE different parameters (such as space). How can you achieve that in z/OSMF? Is there a book that could explain all of this in detail? The books found does not provide this level of detail. Please advice.

    Ivan, I suggest you review the video tutorial series on using z/OSMF Software Management:  https://mediacenter.ibm.com/playlist/dedicated/101043781/1_mzzf31vy/1_f1qhec1j
    The videos describe installing a small fictitious software product, but it gives you the overview.

    I also suggest you review the z/OSMF Guild session recording and slides from last year on installing z/OS 2.5 using z/OSMF Software Management:  https://community.ibm.com/community/user/ibmz-and-linuxone/viewdocument/zosmf-guild-session-3-jan-19-20?CommunityKey=1ca674e5-aada-4194-a16e-059cafe7b807&tab=librarydocuments
    It also provides overview information, but also speaks to some of the unique considerations when installing a new z/OS release, such as master catalogs.

    Regarding your specific question on changing allocated space for the target data sets, that is not an option.  The shipped data sets should all get allocated with 40% free space, and we hope that is sufficient.

    Thank you for your prompt response. I saw your videos and practice with the demo installation, aside that this is my second installation using z/OSMF.

     

    So far, find z/OSMF software management a little unprepared and barebone compared to what we had before, kind of a step back (middle between CBPDO and CPAC). It is such a pity that such innovated approach does not have the same or more capabilities from it was offered on the CPAC. Is there any future enhancement to offer similar capabilities?

    We had several goals with z/OSMF Software Management over the IBM CustomPac Installation ServerPac.  The first was to provide a solution that can be exploited by all vendors for all z/OS platform software, not just by IBM.  The second was to try and simplify installation.  Part of simplification sometimes is to remove unnecessary options.  We believe by defining more intelligent data set space allocation values, then installers won't be required to manipulate that information.  Let me know if there other specific CustomPac functions you believe are necessary but are missing from Software Management.

    Hi Kurt,

     

    I do understand and can relate for defaults values but should provide the option if the user does not want to use them. In my perspective, a replacement product should strive to have at least the same functionality as before.  

     

    In addition to the space management issue, the SM panels does not provide a clue on the relational characteristics of each DSN. For example, which DSN goes to each volume (CAT, RES, USS, ETC.). In a small installation, you can go to each one individually but on larger one like our z/OS serverpac it is a daunting task (in my order there are 1,238 DSN's). Also, All DSN's were assigned to the MCAT, which is opposite to what is recommended (supposedly only essential DSN's should be on MCAT and everything else should be on a UCAT). So far, those are the main areas encountered.

    Ivan, thank you for your observations.  Regarding assigning the target data sets to volumes, if you select an existing software instance as a model, such as your existing z/OS 2.5 or 2.4, then as much as possible the initial configuration will be created to look like your existing z/OS.  That means the data set names and volume selections will match your existing z/OS.  If you do not select a model, then the initial configuration will look like the IBM manufacturing software instance, which is not very helpful.  Did you select a model software instance?

    Regarding assigning data sets to catalogs, if you chose to use your existing master catalog, then based on the data set names, z/OSMF will determine into which catalog each data set will get cataloged.  If you chose to create a new master catalog, then the initial configuration creates only the new master catalog with no user catalogs.  You can of course tell z/OSMF to define new user catalogs and assign data sets to those new user catalogs, but your point is fair, z/OSMF does not offer a default configuration with separate user catalogs for different categories of data sets.  Did you choose to create a new master catalog?

    We tried to use a definition we made for our z/OS v2.4 as a model (even though was initially installed using CPAC), unsuccessfully. We have both versions of Java (31/64 bits), but we unmounted the 31 bit to detect products and applications using it before going to V11.  For some kind of reason, the panels it asked for the 31 bit, even though the 64 was active and did not let us continue. At that point, decided to continue the install without a model.

     

    On the catalog, we selected to have a brand new MCAT to start fresh and to eliminate any unwanted entry into our current catalog structure.

    On the catalog section, we are trying to reroute a HLQ to an existing share catalog, but none of the panel/actions seems to have that option. How could we achieve that?

    Ivan, I believe you chose the option to create a new master catalog during the installation (deployment).  Unfortunately with that option z/OSMF only allows you to create a new master catalog and new user catalogs.  It does not support connecting existing user catalogs to the new master catalog.  This is a function I know we need to address in the future.

    After much effort, we were able to IPL the system. We searched all available documentation (online, order and in z/OSMF), but there were no detailed instructions on how to do so (IPL load sequence). Is there any?

    Since we normally install z/OS as a bare bone system; we are using all the defaults, including the operational optional DSN's that came with it. In previous installations, the system came with a basic RACF setup to facilitate the installation, but when we tried to run the RACF target jobs, failed because the product is not available. Any reason why this is happening? Please advice on how to proceed.
