The Red Hat and Oracle Linux operating systems generally utilize many different permutations of RPMs. Occasionally when vulnerabilities are identified, it is necessary to update or patch some of the OS RPMs.
In order to avoid system downtimes, interruptions in workflows and other issues associated with the new RPMs, we strongly recommend following these best practice guidelines:
Before working with patches or new RPMs, always perform a backup or take a snapshot of the server.
Before installing in the production environment, always test new RPMs in a development or testing environment that is identical to the production environment.
If you encounter any unexpected issues, please contact Customer Support for assistance.
