In data replication, changes made to the original copy of data (known as the master or primary copy) are propagated to the replicated copies to ensure consistency. Replication can occur within a single database

The database clients, such as web browsers or computer applications, do not see the database replication system, but they benefit from close to native DBMS behavior.Primaries and ReplicasMany Database Management Systems replicate the database.The most common replication setup uses a primary/replica...
This topic includes all the data types that are specific to the DBMSs supported in ArcGIS and what their equivalent native format is in ArcGIS.
In Oracle, there can be only one data record whose c1='1' and c2=null. If one more data record is inserted again, a unique key conflict occurs. Restricted by the logical replication capability of GaussDB, up to 20 logical replication slots can be enabled for decoding on the same ...
Oracle GoldenGate is a tool for real-time change data capture and replication. Oracle GoldenGate creates trail files that contain the most recently changed data from the source database, then pushes these files to the destination database. You can use Oracle GoldenGate to ...
Database redundancy replicates data within a database management system (DBMS). Examples include: Database replication (master-slave, master-master). Database mirroring. Clustering. Database replication is more complex but provides granular control over data replication. It is often used for missio...
To forcibly stop a full+incremental real-time synchronization task, you need to manually delete the replication slots that may remain in the source database. For details, see Forcibly Stopping Synchronization of PostgreSQL. If the value of session_replication_role of the destination database is rep...
Acquire can obtain the replication sets from the database rows directly, or it can acquire them from data caches where only data changes are stored. Typically these are either DBMS log record stores or user-written caching databases. In this case, these stores should be considered the sources....
