Hi Peter,

If you implement dataguard or simple physical standby database, it is DR
solution and not HA. You also need double the storage space.

For HA you need some kind of software (SUN Cluster or VCS). You mentioned
about
not purchasing additional license from Oracle so RAC is out of question.


A single RAC system with a single database (also a SPOF) is also not HA.
