1. Go to the Oracle Security Alerts Bulletin for latest Patch Updates: https://www.oracle.com/security-alerts/

 3. In the Patch Update Advisory under the "Affected Products and Patch Information" section search for "Oracle Database Server", and select the Patch Availability Document by clicking "Database" on the right:

4. You will be prompted to sign in with your Oracle account. Sign in under the "Support for Oracle Hardware, Software..." section:
 

5. This is the Patch Availability Document which provides links to download each patch component separately:

To review, the patch components needed are "Database Release Update", "OJVM Release Update, "JDK", and "OPatch".

On the left side under "Patch Search Results" scroll and select "Linux x86-64" (or whatever platform you need).

10. Select "Download", then click the file link to begin download:

*If you select download and it prompts you to enter a password, then it most likely means that your sign in has timed out (which happens fairly quickly and often) and you will need to sign in and start over.

Now that you have the patches downloaded, you can apply each patch manually on the server, or you can use this article to package the files as Broadcom did so you can apply all using the automated Oracle PSU Script.
