How mACB changes a DBA's life

  • 1.  How mACB changes a DBA's life

    Posted 7 days ago

    How did using mACB affect your daily DBA work? Or how do you think it will affect it?

    I was curious about this and played around with AI to get some ideas. I'm sharing the summary below. Does it match your experience?

    I haven't been a hands-on DBA for many years, so I'd like to sanity-check some of these points.
    Is it really possible to make changes in production outside of maintenance windows now?
    I imagine that even if the technology allows it, procedures like change management might still slow things down.

    Do you think there's a lot to learn about mACB?


    Can you share your experience?

    Here is what gpt says:

    Life After mACB – DBA's Quick Notes

    What I Had to Learn

    • IMS Catalog concepts – structure, versioning, active definition tracking

    • Dynamic load & activation – when IMS picks up new PSBs/DBDs and how to roll back

    • DevOps integration – connecting Catalog updates to CI/CD pipelines (Git, Jenkins, etc.)

    • New troubleshooting skills – interpreting Catalog/mACB-related messages and conflicts

    What Changed in My Work

    • No more static ACBLIB builds for every change

    • Faster deployments – changes can go live the same day

    • Less downtime & weekend work – updates happen during business hours

    • Multiple versions in parallel – easier A/B testing and phased rollouts

    • Closer collaboration with application teams

    What We Can Do Now That We Couldn't Before

    • Deploy new transactions without planned outages

    • Run parallel PSB versions in production

    • Provide sandbox environments quickly for developers

    • Support rapid prototyping directly against IMS data

    I'm also posting a "DBA diary" version in the comments for fun.
