If you're going to be looking up spids frequently, then yes, you may want to use a hash. Something like the following (untested) code is what you want: 
my $xpid = 1234;
%procs = map {$_ => 0} @{$dbh->selectall_arrayref(
                         "select spid from v\$process")};
if (defined($procs{$xpid})) {
   print "Pid is in use : $xpid\n";
}
