In a previous post, I shared the OGGRestAPI Python client I built for the GoldenGate REST API. Since then, I kept using it on production deployments, fixing it and adding new features along the way.

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

In a previous blog, I presented how to set up a distribution path between two GoldenGate deployments both secured with NGINX. The method I used there was purely through the Web UI. But GoldenGate

Since the beginning of the year, I had the opportunity to upgrade many GoldenGate setups to 26ai. On two of them, I was facing an issue regarding purge tasks that I could not solve. Since it took

Every time I work on database migrations with GoldenGate, I have the same talks with application teams about missing primary keys. Especially when it comes to LOB replication with GoldenGate. In a

I recently wrote about NGINX reverse proxy reconfiguration after creating or deleting a deployment in GoldenGate. It reminded me that there is an overlooked aspect of the reverse proxy configuration,

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 !).

Configuring an NGINX reverse proxy for GoldenGate is well documented by Oracle, but what is not is the implication of adding or removing deployments. In fact, when modifying your GoldenGate

*Update: this bug seems to be corrected with the latest GoldenGate patch (23.26.2.0.1). If you face this error, try to patch your GoldenGate deployments. Recently, after a successful migration to

If you are licensed for the GoldenGate Management Pack, using the Enterprise Manager plug-in for GoldenGate improves monitoring and management of your deployments. And after migrating to the

While migrating a GoldenGate classic architecture setup with the migration utility, I recently had the following OGG-12020 error: It is a very cryptic error at first glance, but let's try to

*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

Oracle GoldenGate REST API has been around for quite some time now, but I've yet to see it used in practice at customers. Every time I tried to introduce it, it was some sort of novelty. Mainly

Earlier this week, Oracle Database 26ai was released, but GoldenGate 26ai is also available now ! New features were added, but before diving into some of these changes in an upcoming blog post, let's
