Why teams connect IBM Db2 and Oracle DB

Keep IBM Db2 and Oracle DB synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between IBM Db2 and Oracle DB continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • 01 Expose Db2 records that back core business systems to a CRM so sales and support see order or account state.
  • 02 Sync SaaS data into Db2 tables that existing enterprise applications and reports already consume.
  • 03 Keep legacy Oracle applications running while newer services read and write the same data through a synced copy.
  • 04 Write changes from SaaS apps back into Oracle so PL/SQL jobs and reports run on current data.

Common sync patterns

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

What you can sync between IBM Db2 and Oracle DB

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

IBM Db2 objects Oracle DB objects How this pairing syncs
Schemas Namespaces separating synced data from application and system objects. Schemas Per-user namespaces that scope sync permissions and object visibility Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Primary read/write target for syncing rows with SaaS systems or other databases. Tables The primary read/write surface for row-level sync over SQL Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only projections often used to expose curated slices to a sync. Views Curated read-only projections exposed to downstream consumers Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences ID generation relevant when external systems insert rows. Sequences Key generators to respect when external systems insert rows Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Stored Procedures Existing business logic sometimes invoked as part of write paths. PL/SQL procedures and packages In-database logic that can consume or transform synced data Stored Procedures is specific to IBM Db2 and PL/SQL procedures and packages to Oracle DB — each maps to any object or custom field on the other side.
Tablespaces Physical storage layout that operators consider when adding synced tables. Partitions Physical subdivisions relevant when replicating high-volume tables Tablespaces is specific to IBM Db2 and Partitions to Oracle DB — each maps to any object or custom field on the other side.

How changes propagate between IBM Db2 and Oracle DB

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

IBM Db2 Oracle DB Sub-second propagation

DetectionChanges in IBM Db2 are captured at the source via change data capture — no polling loop against its API. Log-based CDC through IBM's replication tooling where licensed.

DeliveryEach detected change is applied to Oracle DB as a row-level write, with types converted between the two schemas.

Oracle DB IBM Db2 Sub-second propagation

DetectionChanges in Oracle DB are captured at the source via change data capture — no polling loop against its API. Log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling.

DeliveryEach detected change is applied to IBM Db2 as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • IBM Db2: No API rate limits; throughput is bounded by instance resources and workload management settings.
  • Oracle DB: Throughput bounded by database resources rather than API quotas.
