01 · What it is

Oracle GoldenGate, made clear.

GoldenGate captures transactions from the redo logs and applies them elsewhere in real time: Oracle to Oracle, but also SQL Server, PostgreSQL, Kafka, BigQuery. It's the tool for zero-downtime migrations and continuous integration: data travels while production never stops.

CDC
change data capture from the logs: minimal impact on the source
Eterogeneo
Oracle, SQL Server, Postgres, Kafka, cloud: it talks to everyone
Bidirezionale
active-active across sites, with conflict management

Zero-downtime migrations

Initial sync + CDC + cutover when YOU want: downtime shrinks to the app restart.

Operational anti-lock-in

Replication to different platforms: the data free to go where it pays.

Live analytic feeds

The ERP replicated to the warehouse without nightly batches.

Governed conflicts

In bidirectional setups the rules are written beforehand: who wins, when, why.

03 · In depth

Log-based CDC and the topologies

GoldenGate reads the redo logs (non-invasive capture), transforms and applies to heterogeneous targets with second-level latencies: uni/bidirectional, star, active-active topologies with conflict resolution; the microservices (distribution/receiver path) replace the old extract/pump; the OCI GoldenGate service is on consumption. It's the tool for near-zero-downtime migrations, integration to Kafka/BigQuery/Synapse and operational replicas.

  • Log-based CDC — capture from the redo: near-zero impact on the source database
  • Eterogeneo — Oracle↔SQL Server↔PostgreSQL↔Kafka↔cloud: the routes you need
  • Active-active — writes on two sites with conflict resolution: extreme continuity
  • Migrazione zero-downtime — replicate, align, switch: the cutover in minutes
  • Microservices — REST and a web console: modern operations, no more fragile scripts
  • Veridata — the source/target comparison row by row: the proof the data matches
04 · Numbers and lifecycle

The numbers that matter.

~s
the typical end-to-end replication latency
min
the downtime of a well-prepared cutover

the OCI GoldenGate model: you pay when it replicates
Successful migrations are prepared: mappings, Veridata and switch rehearsals — day X becomes routine.
05 · Use cases

Where it really pays off.

Upgrades and removals

Versions, platforms and clouds changed without stopping.

CQRS and streaming

Transactional data poured onto Kafka in real time.

Site synchronization

Two active sites on the same information estate.

Downtime for migration is an outdated custom: with GoldenGate you move with the engine running.
