Web Services Manager
WSM allows IT managers to centrally define policies that govern web services operations such as access control (authentication, authorization), logging, and content validation, and then attach these policies to one or multiple web services, with no modification to existing web services required. In addition, Oracle WSM collects runtime data to monitor access control, message integrity, message confidentiality, quality of service (defined in service-level agreements) and displays that information in graphical charts.
Oracle WSM was formerly called Oblix COREsv. Oblix was acquired by Oracle in March 2005.
Oracle WSM ships both as a standalone product running on Oracle Application Server and as part of the Oracle SOA Suite.
This is changed in 11g. WSM not shipped as standalone product since October 2009. In 11g WSM is bundled as part of Weblogic Server, and WSM gateway component is not available.

 Network traffic
Outbound traffic: When configuring the outgoing transport protocol (protocol on which the Web service is invoked) you need specify one of the following protocols: HTTP, HTTPS, JMS, MQ, or even a custom protocol.
Load balancing: Inbound traffic can be load balanced to more than one WSM gateway. This provides fail-over support and greater scalability.
