Zero Downtime (ZDT) Patching for Oracle Fusion Middleware / WebLogic Server
Many Fusion Middleware patches can now be applied to a system without incurring downtime. This is referred to as Zero Downtime Patching (ZDT). ZDT is currently available in some Oracle Fusion Middleware 11g products. Similar support is also available for Oracle Fusion Middleware 12c through a new OPatchAuto feature.
For more details read the document "Introduction to Zero Downtime (ZDT) Patching for Oracle Fusion Middleware / WebLogic Server" (Doc ID 1942159.1), which outlines the following:
• How to identify a Zero Downtime Patch
