No if by active/active you mean both servers share the workload.
While hardware vendors often let customers in the belief that the second cluster node will be active, 95% of cluster implementations today are NOT active/active. While the second cluster node will do some tasks, he is not actively involved in the first node’s primary task such as for example operating a database.
I have work on a active/active implementation using GPFS and Oracle Grid, but even that was a bit unstable. Saying that it was a year ago and some of the bugs may had been ironed out now.

If indeed the only app your are running is Oracle, then you can use RAC, but if you are running other apps as well, HACMP is the way to go...
