When migrating a Coordinated Replicat for a client, I faced a very specific OGG-02454 error that I wanted to share. When using the migration utility on a Classic Architecture Coordinated Replicat, every attempt failed at the checkpoint conversion step with OGG-02454 Trail … not found in checkpoint file. Because the migration utility rolls back the entire migration on any hard…
Upgrading GoldenGate when the source is DB2 for z/OS is not quite the same exercise as upgrading a GoldenGate installation for Oracle. Most of what I described in my generic blogs about planning a GoldenGate upgrade and migrating from Classic to Microservices Architecture is still valid. However, there is an extra layer to deal with. It has to do with…
While working on a client’s GoldenGate 26ai environment, I ran into a NFS-related replication issue that could have been serious, had it happened in production. Here is what happened and how the issue was fixed. The client’s GoldenGate extract was running on a dedicated server, capturing changes from an Oracle 19c source database. Trail files were written on an NFS.…
For some customers, the end of support for GoldenGate 19c in May this year and the migration to Microservices Architecture mean that they have to adapt their patching procedures (if they had any !). Let’s see how to patch a GoldenGate Microservices Architecture out of place efficiently. This guide is designed for GoldenGate 26ai because this version introduces some small…
When patching GoldenGate Classic Architecture, you might encounter an OGG-08048 error when restarting your extracts and replicats. What should you do exactly, and how do you avoid this error in the future ? In fact, this error is easy to reproduce, which also makes it easy to avoid. Usually, it happens when following the official documentation instructions for patching. They…
Is it possible to create a new GoldenGate deployment with the REST API ? This is the question I will try to answer in this blog, based on my experience with the REST API. I will dive in what is done by the oggca.sh script when adding a new deployment and see if we can replicate this with the REST…
Updated in June 2026, based on the latest version of the client. In this blog, I provide GoldenGate administrators with a fully working, production-ready Python client to efficiently handle GoldenGate REST API calls. From extract creation to user management, it has never been easier to manage and monitor your GoldenGate deployments ! Basic OGGRestAPI Python class In a previous blog…
