Hi The compression of redologs occurs in 11g only for resolving gaps in the archivedlogs and not for normal transmissions Data Guard 11g implements a new streaming design that significantly increases the throughput of redo transport in Maximum Performance protection mode (during asynchronous redo transport and when using ARCn processes to resolve gaps). The benefit of these enhancements will be particularly noticeable in high latency ? WAN environments in 11g SSL authentication can be used in lieu of password file to authenticate redo transmission. Note: SSL authentication requires use of PKI Certificates, the Oracle Advanced Security Option and Oracle Internet Directory regards Hrishy --- Binh Pham <binhpham15@xxxxxxxxxxx> wrote: > Do you know if archived logs which are transported > to the Data Guard sites can be compressed for slow > network bandwidth?
