Oracle 11g RAC with DLP 11.6

I have a customer preparing to upgrade from DLP 10.0 to 11.6 and Oracle 10g to 11g.  They have asked about a feature in Oracle, to determine if it will work with DLP.  The question they ask is below:

The Oracle 11g Standard Edition has a feature RAC – Real Application Cluster single node (which means that there is failover for Oracle on a single node).  Is this supported by DLP v 11.6?

Any light you can shed is appreciated.
