Oracle Retail has published a document on My Oracle Support (https://support.oracle.com) that provides you with guidance on how to upgrade from WebLogic11g 10.3.3 to WebLogic11g 10.3.4. The goal of this document is not to be a substitute for WebLogic documentation but to illustrate how Oracle Retail approached and performed its upgrade. 

•  Doc ID: 1432575.1
  This document provides information about how to upgrade to WebLogic 10.3.4 and how to complete related component upgrades as well. Upgrading from WebLogic 10.3.3 to WebLogic 10.3.4 (rather than performing a separate WLS 10.3.4 installation) is recommended so that you do not have to port information and custom settings from your 10.3.3 installation. The paper addresses the following topics:
  • High Level Steps for Applying WLS 10.3.4 Patch and 1.1.1.4.0 Patch Set
  • JRockit Upgrade (optional for Linux and Sun OS only)
  • WLS 10.3.4 Upgrade using Upgrade Installer
  • SOA 11.1.1.4 Upgrade
  • Forms 11.1.1.4 Upgrade
  • Update DB Patch Assistant
  • Post Patch Instructions
  • Validation
