Upgrade a distributed RHEL, CentOS, or Oracle Linux installation of Splunk UBA

Before upgrading Splunk UBA in a distributed deployment, be sure you have verified the Upgrade Splunk UBA prerequisites. Make sure that the prerequisites are verified on each server in the distributed deployment.

Distributed environment upgrade steps

Install Splunk UBA 5.0.5 on the management node only. The upgrade script will update all relevant files on the other Splunk UBA nodes. Ensure that Splunk UBA is running before you upgrade.

To obtain and install Splunk UBA 5.0.5, perform the following tasks on the management node:

  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
  4. Apply the patch with the following command:
    /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.
