Why teams connect Amazon RDS and IBM AS/400

Keep Amazon RDS and IBM AS/400 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 Amazon RDS and IBM AS/400 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 an RDS reporting database hydrated from operational tools without maintaining ETL jobs
  • Sync master data (customers, products, pricing) from an ERP into the RDS databases that power customer-facing apps
  • 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.

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 Amazon RDS and IBM AS/400

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.

Amazon RDS objects IBM AS/400 objects
Read Replicas Low-impact read endpoints often used as the source side of a sync. Journals and journal receivers The change log that enables log-based CDC on journaled files.
Stored Procedures Engine-specific logic that can react to synced rows. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations.
Databases Engine-level databases on the instance that scope a sync's reads and writes. Libraries The schema-equivalent containers that scope which files a sync reads.
Schemas Namespaces within a database used to isolate synced tables. Physical files (tables) The Db2 for i tables mapped directly to sync targets.
Tables The core sync target; rows map to records in connected SaaS systems. Logical files (views) Indexed or filtered views over physical files, usable as read sources.
Views Read-side projections exposed to outbound syncs. Members Sub-partitions of files in legacy applications, flattened or selected during syncs.

How the Amazon RDS and IBM AS/400 connectors work

Amazon RDS

Integration surface
SQL wire protocol of the chosen engine (PostgreSQL, MySQL, MariaDB, SQL Server, Oracle)
Authentication
Database credentials over SSL/TLS, or IAM database authentication on supported engines
Change detection
Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC; enabled through RDS parameter groups, with polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput depends on instance class, storage IOPS, and connection limits

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.
