Cold standby setup with synchronous transfer of transaction data using the Logical Volume Manager

In a data replication scenario both servers are kept in sync. In the event of a failure, the standby database server takes over the workload without any loss of data. The cold standby setup uses synchronous transfer of transaction data using the Logical Volume Manager (LVM) or storage replication.

Challenges:
  • System not available during failover and database recovery
  • In-flight transactions are lost
  • Risk of I/O level corruption despite separate disks for data storage
