Why teams connect IBM AS/400 and MySQL

Keep IBM AS/400 and MySQL 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 AS/400 and MySQL 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

  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • Expose SaaS objects as MySQL tables so legacy internal tools built on MySQL can read live business data
  • Replicate ERP master data (customers, items, pricing) into the MySQL databases behind storefronts and portals

Regional or environment copies

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

Cross-engine sync

Keep the same dataset live in both IBM AS/400 and MySQL, so each workload runs on the engine that suits it.

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.

What you can sync between IBM AS/400 and MySQL

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 AS/400 objects MySQL objects
Journals and journal receivers The change log that enables log-based CDC on journaled files. Views Read-side projections used as outbound sync sources.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Columns Field-level mapping targets with engine-typed values.
Libraries The schema-equivalent containers that scope which files a sync reads. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. JSON Columns Validated semi-structured payloads for nested SaaS data.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Stored Procedures Server-side logic that can post-process synced rows.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Triggers An alternative change-capture mechanism when binlog access is unavailable.

How the IBM AS/400 and MySQL connectors work

IBM AS/400

Integration surface
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
Capabilities
read · write · CDC
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.

MySQL

Integration surface
SQL wire protocol (MySQL client/server protocol)
Authentication
Database credentials entered as a connection string or parameters, with optional SSL root certificate upload and optional SSH tunnel (SSH user + SSH host)
Change detection
Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when binary logging is enabled)
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by connection limits and server resources
