Dataguard and logical standbys for Oracle, replication in SQL Server and  "a 
poor man's RAC" for MySQL.

It depends on HA for what.
For Database, then you have DataGuard which in my experience covers most HA 
needs. You do have RAC, but RAC introduces a whole new level of complexity and 
therefore a new potential point of failure. As Niall mentioned you have various 
replication methods as well.
I guess the real question is what is the business need (the REAL business need) 
and then we can tell you what kind of HA/replication we use.
