Today I faced one issue in newly built server while uploading rpd for migration through EM.
I noticed error from coreapplication as :
Then Navigated to MBean to try my luck for rpd uploading from there, but all parameters were showing unavailable Value.
I explored the solution to it & identified as file - <OBIEE_HOME>/user_projects/domains/bifoundation_domain/sysman/mds/partition1/ai/bi/fragments/mdssys/cust/user/weblogic/deployment.jspx.xml was causing the issue. I deleted it & proceeded with full bounce.
[ Note - deployment.jspx.xml file will get created automatically after you navigate to coreapplication in enterprise manager. But take the backup of the file before deleting it. ]
