Oracle database replication

The Oracle advanced replicationfeatures extend the capabilities of basic read-only replication by allowing applications to update table replicas throughout a replicated database system. With advanced replication, data replicas anywhere in the system can provide both read and update access to a table's data In a replication environment, Oracle manages replication objects using replication groups. By organizing related database objects within a replication group, it is easier to administer many objects together. Typically, you create and use a replication group to organize the schema objects necessary to support a particular database application Understanding Oracle Database Replication Oracle provides its own set of tools to replicate Oracle and integrate it with other databases. In this post, you will explore the tools provided by Oracle as well as open-source tools that can be used for the Oracle database replication by implementing custom code. Methods For Oracle Database Replication The minimum supported version of MySQL for a replication source is 5.7.9. MySQL installed on Compute Instance (such as MySQL on the Oracle Cloud Infrastructure Marketplace) to DB System. Inbound Replication requires a replication channel configured in MySQL Database Service, connecting a correctly configured MySQL Source to a DB System target Oracle replication is a fully integrated feature of the Oracle server; it is not a separate server. Replication uses distributed database technology to share data between multiple sites, but a replicated database and a distributed database are not the same

Data Replication is the process of storing data in more than one site or node. It is useful in improving the availability of data. It is simply copying data from a database from one server to another server so that all the users can share the same data without any inconsistency Storage replication does not have such capability because it does not have visibility in the Oracle database. To the storage layer, everything is in OS data block. Oracle DataGuard Rolling Upgrade Oracle DataGuard has a feature called rolling upgrade SymmetricDS is an asynchronous database replication software package that supports multiple subscribers and bi-directional synchronization Oracle Database Release 19c New Features. The process of flashing back a physical standby to a point in time that was captured on the primary is simplified by automatically replicating restore points from primary to the standby. These restore points are called replicated restore points The state of the art in database replication, CDC (or its equivalent) is the fastest and most reliable way to replicate. For the databases that support this type of functionality (Microsoft SQL Server, MongoDB, MySQL, Oracle, and PostgreSQL), we query the database's internal change log/table every few seconds to get the latest changes

Replicating Oracle data to another Oracle databas

When database-wide primary-key and unique-constraint/index supplemental logging is enabled, each UPDATE statement also writes the column values necessary in the redo log to uniquely identify the modified row in the logical standby database. Oracle Data Guard supports chained replication, which here is called cascade however it's not. The CDC Replication Engine for Oracle databases will use copies of complete Oracle archive logs that are shipped to a secondary system that is accessible to CDC Replication The contents of the redo log was never intended to be used for anything other than recovery (instance or media) on the database that generated it, or in the case of physical replication like Oracle Data Guard, on a binary copy of the database Replication of tables from Oracle to PostgreSQL would be based on changelog (timestamp recorded at SPHMF) irrespective of logged-in users or whether the data is for the investor or distributor. This replication would be done through a batch process on predefined intervals. No transformation will be applied while pulling the data
