5 Upgrade Considerations
Oracle Tuxedo 12.2.2 applications (client and server) continue to run without re-compiling or re-linking, except for the following:
- Application that uses Xerces API
- Problem statement: Xerces upgrade causes incompatibility at code level and binary level. Xerces-C++ 3.2.3 is an API-compatible, although not ABI-compatible, update to the 3.x branch. Code designed for use with Xerces 3 continues to compile, however, existing applications recompile to work with this version.
- Action: Application that uses Xerces API needs to be recompiled with the new libtxml in Release Tuxedo 22c .
