I cannot seem to locate a patch number for 220.127.116.11 for Windows 2003 Server so it may no longer be available. You might want to consider applying a more recent patch, such as 18.104.22.168. You must download the patch from Oracle's Metalink Web site.
Note that you must also have a valid CSI (Customer Service Identifier) to be able to access Metalink. The step-by-step instructions are quite detailed and beyond the scope of this forum but when you download the appropriate patchset from Metalink, a README file with instructions for installing the patch is included. Ensure you have an appropriate back-out plan in place just in case the patch fails. This includes having an appropriate backup of all your databases, as well as the Oracle software and inventory.
