Improve installation CLIST

I have just suffered over two days of Db2 Install Clist and can heartily recommend no-one use it to do a clean Install. The problems are myriad but the absolute number one is when it dies/crashes/abends all input data, apart from two or three random fields, is lost and you must type in all the data again. After the fifth time it died I have given up and will just "do what I used to do" and copy the oldest JCL over to a new lib and do a few "c all" commands and I am good to go. This is not good as I am trying to use z/OSMF to do the "heavy lifting" and so this is realy defeating the whole purpose!

My Idea is that after every panel is left with ENTER to save the data in the users ISPF PROFILE pool. If the CLIST ever finishes correctly then these variables can be deleted and if not then the CLIST can just VGET them to prefill the panels thus enabling quick regen and saving hours and hours of effort.

Quite frankly I am amazed that there is no other Aha Idea around this as when I asked some colleagues they have said it has been pretty bad for the last 20 Years and they have edited it themselves to get it running in the past!

    Hi!

    Yes indeed - I have had a great meeting with Suehli and Debbie and now all is clear. As always I was about 90% to blame as I misunderstood the very first panel instructions about the two fields at the bottom of that first screen. tehse are critical to the CLISTS abiliyt to work. We also used the incorrect SMP/E work flow instead of the proper Db2 Install workflow. My install is now done but I must wait for my sysprogs to double check all of my prefix's, SMS stogroups, USS Paths etc. etc before I proceed and actually finish the install. As far as I am concerened this AHA can be closed.

    Many thanks!

    Dear Roy, Thank you for submitting this enhancement request.

    Our installation/migration SME discussed these issues/suggestions with you at IDUG NA and explained our strategy and latest enhancements towards modernization/simplification of the Db2 for z/OS installation and migration processes.

    Because this enhancement request covers several aspects of the DSNTINST execution, we have broken it down as follows:

    1. When the CLIST dies you are thrown back to square one and must re-enter everything again.

    Solution available: As you navigate the CLIST DSNTINST panels, you can save your input at regular interval. Enter save on the panel command line:

    DSNTIPxx INSTALL DB2 - ...

    ===> save

    and this panel will popup. Select 1. Save and continue.

    +------------------------------------+

    | DSNTIPSV |

    | Save changes in progress: |

    | |

    | Select one. |

    | 1. Save and continue |

    | 2. Save and exit |

    | 3. Continue without saving |

    | |

    | PRESS: ENTER to continue |

    | F1=HELP F2=SPLIT F3=END |

    | F4=RETURN F5=RFIND |

    +------------------------------------+

    When the CLIST dies, you will have the values you entered saved in the output DSNTIDxx member, up to the last save point. It is not necessary to re-enter everything again.

    2. Painful process of having to navigate thru several panels

    Solution available: Generate migration artifacts in background mode. This support was delivered in May 2023 via PH52482/UI91497 & PH52882/UI91519. This is all in our regular documentation as well as in this blog: https://community.ibm.com/community/user/datamanagement/blogs/m-sueli-almeida/2024/05/06/continuous-innovations-db2-for-zos-migration

    Note: The support to installation artifacts is still in our backlog.

    3. IF NE AND &SUBSTR(1,) = $ THEN

    --> IKJ56545I THIS STATEMENT HAS AN INVALID &SUBSTR RANGE OR EXIT CODE EXPRESSION


    IKJ56545I is a TSO/E message. In this case, it is generated by TSO/E because &SUBSTR has an invalid range. Unfortunately, DSNTINST cannot control the display of this message when the CLIST hits this error. This is a bug in our code and it would be very helpful if you could send us the trace in case so we can investigate and fix it.

    As you will see in the blog, we are working on several items to make this process simpler, more user friendly, and with automation. Therefore, we have placed this enhancement request in Future consideration.

    Please do continue to submit enhancement requests to us as customer input is key to shaping the future of Db2 for z/OS.

    Sincerely,

    The Db2 for z/OS Development team
