IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Omit PTFs

My team believed that the OMIT parameter in GO PTF + Option 8 would remove the PTFs from products that I did not want to be installed, but this parameter does not do this. That is, nothing is removed, and all PTFs are installed.


Use Case:

The impact is that in controlled situations, it is sufficient to remove the PTFs from the product, e.g., Content Manager, after installing the PTFs. The problem is that many times PTFs are applied permanently, and it is impossible to remove them. It would be crucial that at the time of application of PTFs, there is some way to omit the PTFs that should not be installed. Thus avoiding problems for client environments.

    .Please open a ticket/CPS with Service. It's possible there is a defect with your scenario, but more likely a misunderstanding in how Omit works. Service will direct you to provide the exact steps used and the debug data needed. This would be DSPPTF and DSPSFWRSC listings before the PTF install, joblog of INSPTF with OMIT parm (use INSPTF instead of GO PTF so I can see OMIT PTFs). Note GO PTF just calls INSPTF command, so it's the same code path. If you install PTFs delayed, then I'll also need the SCPF joblog where the PTFs are installed. Then get another DSPPTF listing after install. Also include how the image catalog was created, that is, multiple PTF groups, cumulative PTF package, singles, etc. Thanks!

    And during this case I opened the case to put in this RFE and the responsible confirmed that the parameter didn't working as expected.

    If you perform a test by creating an image catalog with all the PTFs and during the Load request to remove the PTFs for any product, the list will appear empty, however the PTFs will be applied, so the parameter is not working as expected

    The OMIT parameter on LODPTF, APYPTF, INSPTF commands, and the Omit PTFs list on GO PTF have always been supported. Note the help text on INSPTF (same as GO PTF) says:

    "Specifies the product ID, version, release, modification level, and PTF
    ID for PTFs that should not be loaded. The current state of the PTF is
    not checked before being passed to LODPTF. If the PTF is already loaded
    it is applied. A maximum of 50 PTFs can be omitted."

    Perhaps the PTFs specified to be omitted were already in Loaded (Not applied) status. Also note that the Omit parameter does not remove PTFs that are already temporarily applied. The Remove PTF (RMVPTF) command must be used to remove installed PTFs.

    If you have a scenario where you specified to Omit PTFs and those PTFs were loaded, please contact Service and provide the debug data they request (DSPPTF listing before and after installing PTFs and the GO PTF joblog).

    It sounds to me like this is a bug which should be reported to IBM. The help text on the APYPTF OMIT parameter is pretty clear:

    ----------------------------------------------------------------------------------
    Specifies the PTF numbers that are not applied. Up to 300 PTF numbers
    can be specified.

    Note: The OMIT parameter cannot be specified if single PTF numbers
    are specified for the PTF numbers to select (SELECT) parameter.

    character-value
    Specify the identification number of each PTF to omit.
    ----------------------------------------------------------------------------------

    The text is basically the same for the LODPTF command.

    Is it possible that single PTF numbers were selected?

    I am surprised to hear that the OMIT parameter does NOT omit the specified PTF's. If that is indeed the case, it ain't good. We manage over 100 IBM i installations and bad PTF's have caused huge outages in the past, so we recently implemented a rigorous pre-deploy PTF test procedure so we can omit bad PTF's. Since this procedure was implemented we have not yet found a bad PTF, but I would be most distressed to discover the OMIT parameter is ignored or non-functioning, after all the effort we have put in place to catch those bad ones beforehand.
