Difference between 10g to 11g in Oracle SOA Suite

• Service Component Architecture was followed in 11g and not in 10g

• In 11g all Project SOA components we can put in composite.xml file and deploy to single server, where in 10g we have to deploy each component to the respective server(i.e ESB to ESB server, BPEL to BPEL Server etc..)

• Basically all the SOA components like  BPEL, ESB (Called Mediator in 11g),Oracle Web Services Manager (OWSM) are brought into one place in 11g using Service Component Architecture(SCA) Composite concept.

• The major difference between 10g & 11g would be the app server container. 10g by default runs on OC4J while 11g runs on Weblogic Server.

•  In 10g every BPEL is a separate project, but in 11g several components can make one project as SCA.

• In 10g consoles are separate for BPEL and ESB, but in 11g Enterprise Manager contains all.

• In 10g we have to deploy each project separately, but In 11g we can deploy SCA which contains all.

• In 10g BAM and Business Rules are outside SOA Suite, but in 11g they are in SOA Suite
