hi,
Standby feature is a part of Data Guard and Data Guard is a part of Enterprise Edition!

The Standby feature incl. in Standard Edition since vers. 7.x has reduced functionality in comparison to Enterprise Edition.
- managed standby mode
- log-transfer with net8
etc.

We have a HA-solution, based on the oracle standby feature, which needs no Enterprise Edition, but offers the functionality of Enterprise Edition.
