Why teams connect IBM AS/400 and ServiceNow

Mirror ServiceNow's data into IBM AS/400 so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like ServiceNow through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in IBM AS/400.

Stacksync mirrors Problems, Service Catalog Requests, Configuration Items (CMDB), Users and Groups from ServiceNow into Rows / records, Journals and journal receivers, Data queues, Libraries in IBM AS/400 and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into ServiceNow, so the tool and the database never disagree.

Common use cases

  • Keep CMDB configuration items aligned with asset inventories and cloud resource databases
  • Sync sys_user records with the HR system or identity provider so assignment groups stay accurate
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.

React to changes as they happen

Updates in ServiceNow arrive as row changes in IBM AS/400, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read ServiceNow with a query

Records from ServiceNow are ordinary rows in IBM AS/400; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between IBM AS/400 and ServiceNow

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 ServiceNow objects
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Problems Root-cause records linked to incidents, useful in cross-system reporting.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Service Catalog Requests Requested items and approvals that often trigger provisioning in other systems.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Configuration Items (CMDB) Asset and infrastructure records synced with discovery tools and asset databases.
Rows / records The unit of read and write, accessed via SQL or record-level access. Users and Groups Sys_user and group tables synced with HR systems and identity providers.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Tasks The base task table that incidents, changes, and requests extend.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Knowledge Articles Support content that can be mirrored to help centers or search indexes.

How the IBM AS/400 and ServiceNow 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.

ServiceNow

Integration surface
REST API (Table, Import Set, and Aggregate APIs); SOAP remains for legacy integrations
Authentication
OAuth 2.0 or basic authentication against the instance
Change detection
Polling on sys_updated_on timestamps; instance admins can configure outbound push through business rules or Flow Designer
Capabilities
read · write
Rate limits
Subject to instance-level API rate limits and concurrency semaphores configured by administrators
