Before upgrading Splunk UBA on a single server, be sure you have verified the Upgrade Splunk UBA prerequisites.

Single server upgrade steps

Ensure that Splunk UBA is running before you upgrade, then perform the following tasks to upgrade Splunk UBA on a single server.

  1. Obtain the Splunk UBA Software Update and download the file to the /home/caspida directory. Select version 5.0.5 from the drop-down list. The downloadable archive file is named splunk-uba-software-update_505.tgz.
  2. Extract the archive with the following command:
    tar xfz /home/caspida/splunk-uba-software-update_505.tgz -C /home/caspida

    The following files are extracted:

    • splunk-uba-software-update-000059-505.tgz
    • splunk-uba-software-update-000059-505.tgz.md5sum
    • uba-ext-pkgs-5.0.5.tgz
    • uba-ext-pkgs-5.0.5.tgz.md5sum
  3. Extract the software update package in the /home/caspida directory:
    tar xfz /home/caspida/splunk-uba-software-update-000059-505.tgz -C /home/caspida

    /home/caspida/patch_uba_505/bin/utils/patch_uba.sh -p /home/caspida/patch_uba_505 -e /home/caspida/uba-ext-pkgs-5.0.5.tgz
    The command installs the new Splunk UBA software, restarts Splunk UBA, and then restarts the data sources.
