Active data protection has ensured high availability and supports seamless reporting workloads

Principal DB A at a computer software company with 201-500 employees

In my opinion, Active Data Guard is the most valuable feature. We use the secondary side for reporting purposes, which reduces the load on the primary side. Oracle Data Guard includes functions such as automatic failover, but we use manual managed failover. After some months, we converted our primary to secondary and secondary to primary. Oracle Data Guard is effective in minimizing data loss and provides a good solution for that. The main benefits of Oracle Data Guard include minimizing data loss during a production failure. It is used for maximum availability when paired with Oracle RAC, so if any disruption occurs, we have an alternative Data Guard to convert our load to the disaster recovery site. Oracle Data Guard maintains a high level of data integrity by using archive logs. When a transaction happens, redo logs create archive logs, which are then applied on the disaster recovery side, ensuring that both databases are synchronized.
