WSDL Caching in SOA Server

Yes all the partner WSDLs are cached in the SOA Server and by default they are cached for 24 hours. In order to change the cache time do the following,

Farm_soa_domain > Weblogic Domain > soa_domain* > Right Mouseclick > System MBean Browser > Application Defined MBeans > oracle.as.soainfra.config > Server: soa_server > SoaInfraConfig > soa-infra > Attributes

There is an Attribute "UddiCacheLifetime" defining the external WSDL cache time. By default, the value is set to 24 hours and the minimum time of 300 seconds could be set.
