<DIV><FONT face=Arial size=2><SPAN class=919510311-12122005>Hello, we have a
solution to use PowerDNS as master ENUM server with Oracle database access
via RAC which runs on SunCluster of Solaris9, and those slave ENUM server
maybe BIND9 or others, following is question:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=919510311-12122005></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=919510311-12122005> 1. Do have a
maximal limit for zone in PowerDNS access via database (e.g. Oracle), for
our solution it maybe contains more than 1million zone records in one master
ENUM server, is only the restiction of database file itself?</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=919510311-12122005> 2. In
your PDNS doc said Oracel backend do not support "Master" and "Slave" mode just
support "Native" mode, does "Native" means not support dynamic update DNS
record(RFC2136) or not support zone transfer notification. If "Native"
no support zone update notification message, means only way for zone transfer is
slave ENUM send zone transfer request periodically to master server. But this
would take much network load if contains much more zone
files.</SPAN></FONT></DIV>
