Waiting for offline access to <str>

  Explanation:  The database is either opened or otherwise in use,
  and  the  offline operation can not proceed until this access is
  terminated.   If  the  database  remains  inaccessible  for  two
  minutes, the RMU operation will be terminated.

  User Action:  Determine if the database is opened  (possibly  on
  another cluster node) or being accessed by another RMU user, and
  then free up the database or reissue the RMU  command  when  the
  database is offline.
