WebSphere How To: fix errore ADMG0011E while Application Server deletion

Working on a WebSphere environment I was unable to delete an Application server getting the error ADMG0011E:

An error occurred while deleting the server. ADMG0011E: An unexpected exception occurred AdminException: Exception in removeTargetFromCUs()..

Inside DMGR and NodeAgent logs I wasn't able to find anything related but inside DMGR FFDC, folder I got a log generated during the deletion time frame with following exceptions:

Caused by: CWWMH0121E: Could not read configuration data for composition unit "WebSphere:cuname=<Application_Name>,cuedition=BASE". Error data: Enterprise application data for composition unit "WebSphere:cuname=<Application_Name>,cuedition=BASE" could not be read. at

After some research  I've found this question on  DeveloperWorks and than I've fixed the issue following this steps:

  1. Deployement Manger stop
  2. check inside WAS_INSTALL_ROOT/profiles/Dmgr_ProfileName/config/cells/Cell_Name/applications if an  Application_Name.ear folder with same FFDC name Application_Name was present
  3. If the folder on step 2 was missing check inside WAS_INSTALL_ROOT/profiles/Dmgr_ProfileName/config/cells/Cell_Name/blas and than delete  Application_Name if present
  4. check inside WAS_INSTALL_ROOT/profiles/Dmgr_ProfileName/config/cells/Cell_Name/cus if the  Application_Name folder is present than delete
  5. Deployement Manger start
  6. Full Nodes Sync from WebSphere console
  7. Tried again to delete the  Application server and it worked!
