Object catalog

What Stacksync syncs in IBM AS/400.

These objects sync between IBM AS/400 and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where IBM AS/400 exposes them.

Libraries
The schema-equivalent containers that scope which files a sync reads.
Physical files (tables)
The Db2 for i tables mapped directly to sync targets.
Logical files (views)
Indexed or filtered views over physical files, usable as read sources.
Members
Sub-partitions of files in legacy applications, flattened or selected during syncs.
Rows / records
The unit of read and write, accessed via SQL or record-level access.
Journals and journal receivers
The change log that enables log-based CDC on journaled files.
Data queues
Program-to-program messaging objects sometimes used to hand events off to integrations.
API surface

How Stacksync connects to IBM AS/400.

The connector runs on IBM AS/400's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.

Use cases

What teams run on the IBM AS/400 connector.

IBM i, the platform descended from the AS/400 and now running on Power Systems, is operated by IT and ERP teams in finance, manufacturing, and distribution that keep core transactional applications on it. Its Db2 for i database is integrated into the operating system itself, so decades of order, inventory, and financial records sit in Libraries and Physical files. That history gives the platform strong data gravity: modernization teams need its data in cloud CRMs, ERPs, and warehouses without rewriting the applications.

  • IBM i system administrators
  • IT / ERP admins
  • Data engineering
  • Modernization teams

  1. Run a two-way sync between Db2 for i files and Salesforce or HubSpot so RPG-era applications and the CRM stay consistent.

  2. Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.

  3. Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

  4. Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.

  5. Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.

  6. Replicate Physical files (tables) from application Libraries to a cloud warehouse so analysts work with order and inventory Rows / records without querying the production system.

FAQ

IBM AS/400 connector FAQ

What can I sync with the IBM AS/400 connector?

IBM AS/400's core objects — Libraries, Physical files (tables), Logical files (views), Members and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to IBM AS/400?

Via SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access, authenticated with IBM i user profile credentials (database credentials). Changes are detected as follows — journal-based CDC by reading journal receivers on journaled files; polling as a fallback. Stacksync manages rate limits, retries, and schema changes automatically.

Is the IBM AS/400 connector two-way?

Yes. Changes made in IBM AS/400 propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does an IBM AS/400 integration take to set up?

Most IBM AS/400 integrations go live in minutes: authenticate IBM AS/400 and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is IBM AS/400 data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. IBM AS/400 data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
