    Moving from Rdb to Oracle or PostgreSQL on OpenVMS, Denys Beauchemin

    This presentation explains how to move the storage for your existing
    OpenVMS application from legacy Rdb to Oracle or PostgreSQL while the application remains on OPenVMS.

    It sounds like the delay of Rdb is pushing some customers
    to go elsewhere.

    Porting Privileged Code Applications and Device Drivers to x86, Camiel Vanderhoeven

    Almost all user application code should just "compile, link and run"
    when migrating from OpenVMS on Alpha or Integrity to OpenVMS on x86.
    However, if you're porting a program that uses privileged code or a
    device driver, there is a good chance that you will have to make some
    changes to your code. This session will explore what to look out for in
    your code, and how to adapt your code to run on x86.

    That must be the hard core stuff!

    What is the current release schedule ? Have they been able to say
    what the problems with completing the port might be ?

    Not really as it sounds like incremental changes stuff.

    Hard core would be implementing a rmmod that works on VMS. :-)

    (Or implementing support for plug-in filesystems... :-) )

    I think the thread "New VSI post on Youtube" from mid August
    has all the latest.

    Given that we are still waiting for Rdb and MySQL/MariaDB for
    VMS x86-64, then taking a look at Mimer makes a lot of sense.

    Mimer does not have a high media profile - not in the general
    IT industry and not in the VMS community.

    But is is there and it is available for VMS x86-64. And it
    supports a wide variety of access: embedded SQL, JDBC, ODBC.

    I have covered it a few times:

    https://www.vajhoej.dk/arne/articles/vmsdb.html#mimer

    https://www.vajhoej.dk/arne/articles/vmsdbx.html#embsql

    Product page is:

    https://developer.mimer.com/products/product-overview/

    Download page is:

    https://developer.mimer.com/products/downloads/

    And I really like to see OpenVMS listed as supported OS
    at same level as Windows, Linux and macOS!

    :-)
