Oracle goldengate is composed of the following components.
Figure 1 2 illustrates the logical architecture of oracle goldengate for initial data loads and for the synchronization of dml and ddl operations.
Trails or extract files.
Integrating oracle goldengate into a cluster if you installed oracle goldengate in a cluster take the following steps to integrate oracle goldengate within the cluster solution.
Utf8 data is converted to utf16 by oracle goldengate before writing it to the trail.
13 2 configuring oracle goldengate to assume identical metadata.
This topic outlines the oracle objects and operation types that oracle goldengate supports for the capture and replication of ddl operations.
To replicate truncates if supported by oracle goldengate for the database in an active active configuration the truncates must originate only from one database and only from the same database each time.
An additional extract process known as a data pump is recommended to be used on the source system so that captured data can be persisted.
Oracle goldengate supports a time type range from 00 00 00 to 23 59 59.
This is the basic configuration.
It is intended to help determine whether classic or integrated capture is the more appropriate mode to replicate a specific database.
Spin up a linux virtual machine on azure cloud.
Using this technology it enables cost effective and low impact real time data integration and continuous availability solutions.
5 1 overview of oracle goldengate capture and apply processes.
Real time replication of transaction data from an on premises database to azure blob storage and azure data lake gen2 using goldengate goldengate for big data.
Utf32 is not supported by oracle goldengate.
Oracle goldengate moves committed transactions with transaction integrity and minimal overhead on the infrastructure.
Bi directional replication of truncates is not supported but you can configure these operations to be replicated in one direction while data is replicated in both directions.
When source and target tables have identical metadata definitions use the assumetargetdefs parameter in the replicat parameter file.
This parameter directs replicat to assume that the target definitions are the same as those of the source and to apply those definitions to the replicated data when constructing sql statements.
