About Oracle Data GuardLearn More

Data guard is a solution from Oracle to implement Standby Database. which is usually used for system stability and preventing various failures. Dataguard provides the highest level of access to the database for the database system. Also, when a database fails, it can be replaced with a healthy database and reduce the amount of database unavailability. Dataguard can minimize the amount of loss. Dataguard also supports heterogeneous systems, which means that the main and standby databases can be different, for example, Linux and Windows Server. One of the most important disadvantages of Dataguard is that if the network connection is interrupted, it will not be possible to exchange information, which means that any changes made to the main server will not be applied to the standby server. The next point is that the version of the main and standby database must be Enterprise. Dataguard is one of the features of the Enterprise version of Dataguard.
