Explain Enhanced database mirroring in sql server 2008Data base mirroring in SQL Server 2008 is enhanced by:
- Automatic Page Repair: The principal is enabled and mirror computers for recovering transparently from 823 and 824 errors on data pages, with a request for a fresh copy of the page that is corrupted from the mirroring partner.
- Improved Performance: The outgoing log stream is compressed by SQL Server 2008 for minimizing the network bandwidth that is required by database mirroring.
- Enhanced Supportability: Additional performance counters for enabling more granular accounting of the time, which is spent across the different stages of DBMS log processing. Dynamic Management Views and extensions of the existing views are included, for exposing additional information that is concerned to mirroring sessions.
