Smart Update is a standalone Java application that you use to upgrade the software installations quickly and easily with maintenance patches and maintenance packs. For Oracle Fusion Middleware 12c, Smart Update is no longer supported.
In previous releases of Oracle WebLogic Server, you could patch your Oracle WebLogic Server software using a utility called Smart Update. In Oracle Fusion Middleware 12c, Oracle WebLogic Server users can use OPatch to apply patches for both Oracle WebLogic Server and for Oracle Fusion Middleware.
OPatch offers many of the same features as Smart Update, but it has a different set of commands and command options. Oracle WebLogic Server users who are familiar with Smart Update should use this guide to get familiar with OPatch.
