    Hi,

    We have installing Cloud Pak for data 3.5.2 and when we try to install Data Virtualization, we get a UTC minimum requirement below error:

    ..

    ..

    2021-06-11_15.09.15,300_UTC INFO current value: 250 32000 32 128

    2021-06-11_15.09.15,356_UTC INFO minimum requirement: 250 256000 100

    4096

    …

    ..

    Any ideas how to set the semaphore settings?

    Try the following..

    -

    Navigate to OpenShift Web Console -> Nodes

    page.

    -

    Entered the following 2 commands on each

    node:

    echo

    250 256000 100 4096 > /proc/sys/kernel/sem

    echo

    "kernel.sem=250 256000 100 4096" >> /etc/sysctl.conf

    Once you have entered the commands, reinstall the Data

    Virtualization instance from

    the Web GUI and it should install correctly.
