Why teams connect IBM Db2 and Oracle Fusion Cloud HCM

Put your workforce data where your apps can reach it: IBM Db2 and Oracle Fusion Cloud HCM share the same people, positions, and org structure in real time.

Oracle Fusion Cloud HCM is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. IBM Db2 is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Assignments, Jobs, Positions, Departments (Organizations) in Oracle Fusion Cloud HCM need to exist as queryable Tablespaces, Databases, Schemas, Tables in IBM Db2 before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Tablespaces, Databases, Schemas, Tables in IBM Db2 with Assignments, Jobs, Positions, Departments (Organizations) in Oracle Fusion Cloud HCM field by field, in real time. You decide which system owns which fields — Oracle Fusion Cloud HCM typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Replicate Db2 tables into a cloud warehouse continuously instead of nightly batch extracts.
  • 02 Keep reference and master data aligned between Db2 and newer cloud databases during modernization projects.
  • 03 Keep Positions and Departments aligned between Oracle HCM and a finance/ERP system so cost centers and reporting structures match.
  • 04 Sync Absences (workerAbsenceEntries) into a scheduling or workforce-management database for coverage planning.

Common sync patterns

Mirror people records into the database

Records maintained in Oracle Fusion Cloud HCM land as queryable Tablespaces, Databases, Schemas, Tables in IBM Db2, so internal apps and dashboards read live data instead of a periodic export.

One directory of record

When a person record is added, changed, or deactivated in either system, the matching row in the other stays current, ending dual maintenance.

Reporting and analytics on current data

Assignments, Jobs, Positions, Departments (Organizations) replicate into IBM Db2 where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

What you can sync between IBM Db2 and Oracle Fusion Cloud HCM

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 Fusion Cloud HCM objects How this pairing syncs
Databases The connection target; each database holds the schemas a sync addresses. Workers (publicWorkers) Person master with personNumber, names, national IDs, and work relationships; synced two-way via the /workers resource, which replaced the desupported /emps resource. Databases is specific to IBM Db2 and Workers (publicWorkers) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Schemas Namespaces separating synced data from application and system objects. Assignments Child of a worker's work relationship carrying job, position, department, location, grade, and manager; effective-dated, so writes go through PATCH with an effective date. Schemas is specific to IBM Db2 and Assignments to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Tables Primary read/write target for syncing rows with SaaS systems or other databases. Jobs Job catalog reference data; commonly read out to align titles and job codes in a warehouse or written to keep downstream systems consistent. Tables is specific to IBM Db2 and Jobs to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Views Read-only projections often used to expose curated slices to a sync. Positions Position-management records used where positions control headcount; synced to keep vacancy and reporting structures aligned with finance/ERP. Views is specific to IBM Db2 and Positions to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Indexes Support fast key lookups on sync match columns. Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. Indexes is specific to IBM Db2 and Departments (Organizations) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Stored Procedures Existing business logic sometimes invoked as part of write paths. Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Stored Procedures is specific to IBM Db2 and Locations to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between IBM Db2 and Oracle Fusion Cloud HCM

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 Fusion Cloud HCM 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 written to Oracle Fusion Cloud HCM through its API, with automatic retries and rate-limit backoff.

Oracle Fusion Cloud HCM IBM Db2 Sub-second propagation

DetectionChanges in Oracle Fusion Cloud HCM are captured at the source via change data capture — no polling loop against its API. Atom feeds expose changes-only feeds for key events (new hire, termination, assignment change).

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 Fusion Cloud HCM: Oracle publishes no fixed per-tenant REST rate limit; pages are capped via limit/offset and Oracle recommends client-side throttling, backoff, and using HDL for mass loads rather than transactional REST.
