Oracle Golden Gate Replication

Source and target tables.

Oracle golden gate replication.

To support the continuous extraction and replication of database changes oracle goldengate stores records of the captured changes temporarily on disk in a series of files called a trail. After you start oracle goldengate processing an effective backup routine is critical to preserving the state of processing in the event of a failure. The software provides capture routing. Spin up a linux virtual machine on azure cloud.

The following example illustrates such a case. 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. The product set enables high availability solutions real time data integration transactional change data capture data replication transformations and verification between operational and analytical enterprise systems. 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.

Unless the oracle goldengate working files can be restored the entire replication environment must be re instantiated complete with new. This scenario performs an instantiation of oracle goldengate replication using the default handlecollisions logic to show what happens if column values are missing when replicat tries to convert the update to an insert. The product set enables high availability solutions real time data integration transactional change data capture data replication transformations and verification between operational and analytical. 5 9 backing up your oracle goldengate environment.

A trail can exist on the source system an intermediary system the target system or any combination of those systems depending on how you configure oracle. I have done 2000 table replication with goldengate or sql server replication tool for dwh databases in many clients. Oracle goldengate 12c offers a real time log based change data capture cdc and replication software platform to meet the needs of today s transaction driven applications. See predefined database service names for autonomous data warehouse cloud.

To configure the wallet create a sqlnet ora file in the oracle client location in the oracle goldengate cloud service instance. Shrinidhi kulkarni staff solution engineer solution engineering na technology oracle. Following are the configuration steps.

Both tables are named sample. 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.
