Spring JAXB Performance Patch For Oracle Soa Suite 11g (Doc ID 1356883.1)

Last updated on SEPTEMBER 12, 2011

Applies to:

Oracle SOA Platform - Version: 11.1.1.4.0 and later   [Release: 11gR1 and later ]
Information in this document applies to any platform.

Symptoms

SOA 11g has a performance issue in Spring Context and there seems to be heavy lock contention because each request seems to be invoking the JAXB classloader. This will obviously not scale and will also have a latency overhead even on a single threaded basis.
