Stelo + Oracle

Stelo helps you connect data from Oracle

Oracle’s relational database products can process vast amounts of data but extracting that data for downstream processing can burden already highly loaded production systems. Stelo is a cost-efficient, low-impact, and real-time data replication software for Oracle data environments.

Over the last 30+ years, Stelo has evolved alongside databases like Oracle, allowing us to create the most resilient, robust, and efficient solution for offloading heterogeneous source data out of your Oracle database. Stelo’s vendor-agnostic data replication and migration technology is a responsive, agile solution that supports Oracle databases as both sources and destinations.

Stelo can connect all source and destination types for every database, so you can move data from Oracle to anywhere. Stelo also works seamlessly with Data Guard. Easily replicate millions of transactions per hour and transfer data sets over 1TB—without necessitating any production downtime to accommodate. Stelo also makes it easier to handle large JDE data sets.

Oracle Replication Experts

Oracle GoldenGate customers often find themselves “half-supported” when troubleshooting the non-Oracle halves of replication pairs. Stelo has extensive experience with all supported source and destination platforms to ensure that customers will be supported in all aspects of their replication pairings.

Flexible Deployment Icon_Noun 4351350_Green Customizable


Avoid vendor lock-in. Stelo uses heterogeneous replication for bi-directional support across all source and destination types. Our open-standards approach allows us to remain vendor-agnostic while providing highly flexible deployment models.

Rapid Deployment Icon_Noun 3967969_Green Quick Setup

Rapid Deployment

Streamline your deployment plan without costly delays. Stelo typically deploys in less than a day and cuts production time down from months to only weeks.

 Rapid Deployment Icon_Noun 3967969_Green Easy-to-Use

Set it and forget it

Simple installation with GUI interface, configuration wizard, and advanced tools makes product setup and operation straightforward, with no programming needed. Once running, Stelo reliably operates in the background without requiring dedicated engineering support to maintain and manage. Alter, add, and drop schema changes are replicated automatically.

Near-Zero Footprint Icon_Noun 1465960_Green Low Impact

Near-Zero Footprint

Our process provides ultra-low CPU load (less than 1% typical) to minimize production impact and avoid operational disruption. No source or destination software installation required. Only transfer data you need thanks to Dataset Partitioning.

Data Scalability Icon_Noun 1304652_Green Cost-Efficient

Unlimited Connections

A single instance can support multiple sources and destinations without additional licensing. The Stelo license model is independent of the number of cores to either the source or destination, so you only pay for the capacity required to support the transaction volume. Your data ecosystem can change over time without additional costs.

Automatic Restoration Icon_Noun 4647448_Green Reliable

Automatic Recovery

If a connection is broken, no data is lost. Stelo will automatically resume replication without needing to re-baseline in the event of a connectivity failure.

Integrated Bidirectional Data Replication into the Cloud

The company had a payment processing platform and web apps for customer acquisition running separately on Informix and Oracle that were not yet integrated or aligned. Each platform had three different data structures and they did not want to be locked into a single platform or database in the future. While they created a data model to get alignment in AWS - their cloud data required bidirectional Data Replication between Aurora MySQL and the Informix and Oracle systems still used on the backend.

Stelo’s expert technologists were able to troubleshoot a tricky technical challenge to make Onyx CenterSource's data ecosystem flourish.



How long does Stelo take to deploy?

Stelo is designed to make all deployment steps easy and straight forward with many automatic and automated procedures. You can choose which tables, rows, and columns you want to replicate, ensuring that data is replicated efficiently from one datatype to another without complex programing. A typical deployment has you up-and-running in hours, not days.

This is a key area where you can separate the wheat from the chaff. The best replication solutions deploy in under 24 hours. The worst require a week or more of configuration. Deployment time is also a good way to assess reliability. If the initial configuration is complex and time-consuming, you can expect stability and performance problems to arise in the future.

Baseline copies of data should not require more than 24 hours to create unless you are replicating an unusually large amount of data. If initial customizations take a lot of time upfront, you can expect similar lags when customizing in the future as well. High-performance software does not require much tweaking, and you should be wary of the reliability and accuracy of solutions that require extensive reprogramming.

Can Stelo handle high-volume requirements without breaking my bank?

Stelo can handle large-scale data transfers replication with sub-second latency. A single instance can support multiple sources and destinations without additional licensing. The Stelo model is independent of the number of cores of either the source or destination—so you only pay for the capacity required to support the transaction volume. connections. This cost-efficient method merges source data flows into one stream, and then it is applied to any number of subscribing destinations. Stelo delivers enterprise-level performance without enterprise-level cost.

Does Stelo use source resources?

Unlike trigger-based replication software that can consume quite a bit of production resources, Stelo is built to have a near-zero impact on production databases. It’s deployed on an intermediate server between the source and destination databases, resulting in virtually no resource drain on production infrastructure.

Can Stelo use pre-generated tables or indexes to migrate my Oracle JDE data from Db2 to SQL Server or MySQL?

We encourage customers to configure Stelo’s software to create the destination tables on SQL Server and MySQL. In part, this is to ensure the proper mapping of change data captured on the IBM i system and the destination table. Also, if your high availability (HA) software utilizes *AFTER images only for capturing change data, then Stelo’s software must rely upon a synthetic column (the Relative Record Number or "RRN") to uniquely identify the row in the destination table, and it is unlikely that the Oracle JD Edwards (JDE) tool would provide this column. Therefore, it is best to allow Stelo to create the destination, including this column for each table. Alternatively, if the HA software configures *BOTH images in the journals then we can dispense with the RRN column and just utilize any unique index (including a primary key) to identify rows.

Another issue that should be addressed in the planning stage is the use of Unicode datatypes on the destination SQL Server. We strongly encourage customers to use NCHAR/NVARCHAR data types for SQL Server, as this provides the greatest fidelity when mapping data from IBM i EBCDIC to Windows and other non-EBCDIC environments. Our recommendation is to allow Stelo to create the tables and exploit UNICODE data types, and then use the tool to create any additional indexes.
