how VVR can provide the data integration for oracle database files
one of my customer want to build a disart recover cluster for oracle db on WAN. They choose an opensource DRBD solution before, but they got some trouble on it . We sugguest them to choose VVR to do this. But we are wondering how VVR can provide the data integration for oracle database files like control file and redo log in async mode. In DRBD async mode, when the primary node failed, sometimes the oracle database file (control file or redo log) on backup node will be corrupt because some block transmission lost.
