EBS 11i or R12 supports only physical standby database as part of its Data guard strategy. It does not support Active Data Guard. The concept of Active Data Guard is such that it is open READ ONLY mode while still the log is being applied and to login to EBS you need the DB in READ WRITE mode.

Well, theoretically it would support logical standby, but from what Oracle told us at a DG workshop, it is simply not realistic running logical standby with EBS and nobody is doing it.

Physical standby or Logical Standby? See notes 452056.1 and 341437.1 on Metalink.
