BPEL preference values Overwritten after Server RESTART in Oracle SOA 11g

You can set default and current BPEL Preference values from the EM: 

1) Navigate to: Farm_soa_domain > weblogic domain > your_domain > soa_server1 > right click menu > system Mbean browser > oracle.soa.config > server:soa_server1 > SCAComposite > your project > SCAComposite.SCAComponent > processName 

2) Click the properties attribute, then goes to a tableview. You will see all properties you set in design time, and be able to edit them as well.

2) Click Operations tab. 
3) Click on the Attribute Save. 
4) Click the Invoke button. 
5) Click Return.
