Updating the OS of a DB Instance

To improve database performance and security, the OS of a DDS instance needs to be updated timely.

Every time you upgrade the kernel version of your instance, DDS determines whether to update the OS and selects the right cold patch to upgrade the OS if necessary.

Updating the OS does not change the DB instance version or other information.

In addition, DDS installs hot patches as required to fix major OS vulnerabilities within the maintenance window you specified.
