IBM DB2 for i Data Replication With Stelo

IBM DB2 for i data replication with Stelo replicates data in real-time from iSeries and AS400 databases to other relational databases, No-SQL repositories and Big Data stores. Stelo utilizes journal-based change data capture to minimize latency, maximize scalability, ensure accuracy, and optimize performance, making it one of the most powerful data integration tools available today. In addition to DB2 for i, Stelo supports DB2 LUW and popular data stores including Oracle, Microsoft SQL Server, MySQL, Informix, Big Data platforms, and more.

Why Replicate?

The short answer is simple: data availability. Information is the lifeblood of modern business and data replication ensures that accurate, current data flows freely across an organization. Efficiently sharing data optimizes reporting, analysis, app development, high availability, and other mission-critical functions.

Stelo excels in heterogenous environments, seamlessly replicating DB2 for i-originated data into other data stores at latencies of less than one second. As such, IT professionals can utilize the unique characteristics of non-DB2 for i data stores with up-to-date DB2 for i data.

Here are the most common ways that customers leverage Stelo to improve performance, reduce costs, and minimize risk:

  1. Reducing Load on Legacy Systems
    Reporting on legacy DB2 for i databases tends to either reduce performance or require expensive hardware upgrades to offset those performance reductions. As such, many organizations offload their reporting to a data store that scales more cost-effectively such as Microsoft SQL Server.
  2. Zero Downtime Cloud Migrations
    Companies are increasingly migrating to Azure, Amazon Web Services, and private clouds. However, maintaining data integrity and preventing interruption of mission-critical functions during the migration can be a major obstacle.  Real-time data replication solves this by creating a parallel environment so that an IT professional can test the migration thoroughly before permanently shifting to the cloud.
  3. Big Data & Business Intelligence
    Big Data platforms such as Cloudera or AWS Aurora offer powerful new business intelligence capabilities that DB2 for i does not. SQDR replicates DB2 for i to Kafka/JSON to make accurate, up-to-date data available to Big Data platforms, unlocking the potential of these powerful new data stores.
  4. Application Development & Application Refactoring
    Many organizations find developing applications using DB2 for i to be challenging. Stelo customers often use replication to move data to a more desirable application development environment or to refactor existing applications.

Stelo’s DB2 for i-Specific Features

Stelo has used its 25 years of IBM database experience to supercharge replication for DB2 for i. We have encountered and addressed most, if not all, replication challenges specific to the platform and have built Stelo to address a number of unique challenges. These include replicating tables even if they do not have keys on them and using DDS if tables are not defined using SQL. We also offer remote journal support, multi-member support, and support for journal options MINENTDTA (*FLDBDY) and IMAGES (*AFTER).
