Getting started with Oracle Linux ULN patch analysis

This topic explains the process of using TrueSight Server Automation to analyze the Oracle Linux (OL) Unbreakable Linux Network (ULN) systems in your environment to verify whether they require patches and updates. You can use TrueSight Server Automation for analysis, download, and deployment of patches on the Oracle Linux ULN systems. 

Patch management for OL ULN

TrueSight Server Automation supports patch management on Oracle Linux ULN systems using the out-of-the-box patching solution. 


Make sure that the following prerequisites are met:

  • A patch repository must be on a Oracle Linux server.
  • A repository server must have the following utilities and commands:
    • yum or dnf - To analyze and deploy patches
    • createrepo - To create metadata
    • reposync - To download RPMs and metadata
  • The ULN is set up on the Oracle Linux system. For more information, see Setting up ULN .
  • If you want to create a repository for storing Oracle Linux 8 patches on an Oracle Linux 7 system, do the following to add the Oracle Linux 8 GPG key:
    1. Log in to the Oracle Linux 7 system.

    2. Run the following commands:

      # wget -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
      # rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

Patch management tasks

Perform the following tasks to start patch management of the Oracle Linux ULN systems using the out-of-the-box patching solution:

See Walkthrough: Basic patch remediation for a description of how to package and deploy patches to servers requiring remediation. The walkthrough describes a process for Windows, but the process is the same for Linux.
