Automatic security updates
For new installations of Matillion ETL from version 1.73 onwards, and universal installer installations from 29th September 2023, automatic updates of security patches (
yum update –security) are set to run daily on all Matillion ETL environments on CentOS 8 and RHEL 8.
To run automatic updates, the following service is enabled by default on the instance:
Updates will run daily at 6:00am.
Checking the service status
To check the status of the update service, use the following command:
systemctl status dnf-automatic-install.timer
If the service is running correctly, this will produce output similar to the following:
