I tried "rndc flush", it did not take effect.

Servers has been setting:
--------------------------------------------------------------------
@       IN      SOA     root1.domain.com.       admin-dns.domain.com. (
20052012;    Serial
3H;                Refresh
15M;             Retry  
1W;               Expire 
1D;                Minimum TTL
)


Need I change parameters above   ?
