Install OS updates

The CID runs two operating systems: Oracle Linux on the host and Windows IoT inside the embedded OpenLab CDS virtual machine (VM). Microsoft and Oracle security patches are published to CID Hub shortly after Microsoft and Oracle release them. This page is for the lab administrator or IT operator who confirms the selected updates and starts the install.

CID Hub keeps each server template and CID pointed at a current Windows update and a current Linux update by default. If the selected update is later obsoleted or removed from CID Hub, CID Hub automatically switches the selection to the latest applicable release. The new update downloads in the background so it is ready for an administrator to install.

important

Operating system patches close known security vulnerabilities. Apply them promptly after they appear in the Updates Ready state. Delayed OS updates leave the CID and the connected instruments exposed.

Prerequisites​

Before you start, make sure these prerequisites are met.

  • You must have an administrator role to install OS updates.
  • Each CID you plan to update must have Allow Changes turned on.

Install the selected OS updates​

Use this procedure to start the selected OS updates without duplicating the general update workflow.

  1. Open Apply updates.
  2. Start the install by using the method that matches your rollout:
    • To update several CIDs at once. Use the CIDs list.
    • To apply all pending changes to one CID. Use the CID's Software tab.
    • To install only the Windows update or the Linux update. Use the CID's Software tab and start only that update.
  3. If you install OS updates with other changes, see the Installation order section of Apply updates.
caution

Do not install OS updates while instruments are running on the CID. A Windows update can restart the embedded VM and interrupt active OpenLab CDS sessions.

What to expect during the install​

OS updates behave differently from OpenLab CDS and driver installs.

  • The CDS VM reboots after a Windows update. Some Windows updates require the embedded VM to restart. Recent activity on the CID's Summary page reports the reboot and marks the install complete after the VM is back online.
  • Windows updates retry automatically. If a Windows update installation fails, the CID retries the installation up to 5 times at 60-second intervals before reporting the update as failed. The CID keeps running on its current Windows patch level.
  • Linux updates install packages, then the CID agent. A Linux update can include OS packages, a new CID agent, or both. Packages install first. If any package fails after the same 5-retry, 60-second pattern, the agent step is skipped and the CID stays on its current Linux update version. If the agent fails to start, the previous agent is restored automatically.

For the full failure-handling behavior across all components, see the What happens on failure section of Apply updates.
