prstat output in Solaris 11

Looking at prstat output in Solaris 11, something has clearly changed from Solaris 10 prstat version, since the results are quite different.
Looking at an x86 server with S11+SRU7.5, the Oracle instance is eating(RSS) 57GB memory from a machine that only has 14GB memory in total. Is RSS calculated now with used memory+swap? if so, whats the SWAP column for then?
NPROC USERNAME SWAP RSS MEMORY TIME CPU
82 root 2755M 2003M 3.3% 4:19:21 0.8%
46 oracleoc 61G 57G 96% 0:22:08 0.0%
11 gdm 609M 143M 0.2% 0:02:53 0.0%
5 daemon 36M 13M 0.0% 0:01:31 0.0%
RSS
The resident set size of the process (RSS), in kilobytes
(K), megabytes (M), or gigabytes (G). The RSS value is
an estimate provided by proc(4) that might underestimate
the actual resident set size. Users who want to get more
accurate usage information for capacity planning should
use the -x option to pmap(1) instead.
