Thanks your reply, so in theoretically there is no limite power the zone number for PDNS. For the update topic, I got following info from the PowerDNS Manual Table A-6, says no support Master and Slave by Oracle backend. The Native not support dynamic updates(RFC2136), but could support normal DNS zone transfer notification and respond the request of zone transfer from slave ENUM server, right?

Table A-6, Oracle backend capabilities:
Native Yes 
Master No 
Slave No 
Superslave No 
Autoserial Yes 
Module name oracle 
Launch name oracle

PowerDNS is only restricted by the database. We know of Oracle powered
PowerDNS installations with over 3 million domains.

The Generic Oracle backend supports master/slaving, and native. Native means
that oracle replication is used. PowerDNS does not support dynamic updates
at this time, but it could easily enough, especially on trusted networks.

Let me know.

Good luck!
