I had Presentation Administrator privileges on 11g. But suddenly I lost the privilages. In EM the log said “The GUID for user has changed. This could result in catalog access issues…………” .
As I googled I realized that users are identified by GUIDs and not names. So when migration occurs from one environment to another then GUIDs change so the users lose their privileges.
To fix this issue, in NQSconfig, we need to set the parameter FMW_UPDATE_ROLE_AND_USER_REF_GUIDS = YES and restart the servers. After setting we need to reset the parameter to NO and restart again.
