Hi,
Is there any log file on BI ServerĀ that writes the changes in the application roles on EM?
Not really ....
That part could in theory be caught if you enable extra logs at the "web server" level of Weblogic Admin server, but you would only see the page has been loaded, a form posted etc.
If you write about your use case it's possible to give you different alternatives ...
Dear,
What I know is the entire Policy Store (which contain roles in em) exists as a single file called as the system-jazn-data.xml. This file is available under {Middleware_Home}/user_projects/domains/bifoundation_domain/config/fmwconfig directory.
Please see if this can help you.
Regards
Naeem K.
Yes, in OBIEE 11g they are written in that file, in OBIEE 12c it's a different story again, but there isn't a log saying when/who/what changed.
If required must be done outside OBIEE/Weblogic.
