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.
Prerequisites
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:
- Log in to the Oracle Linux 7 system.
Run the following commands:
# wget https://yum.oracle.com/RPM-GPG-KEY-oracle-ol8 -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:
Step | Related documentation | |
|---|---|---|
1 | Create a user role with the required authorizations for patch management. A user who is a member of the BLAdmins role can perform all the patching-related tasks. | |
2 | Configure the global catalog parameters. | |
3 | Download the metadata and payload using the offline downloader utility. | |
4 | Create a patch catalog. | |
5 | Create a Patch Analysis job. | |
6 | Perform the patch remediation. |
Where to go from here
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.
