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…
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 also exposes a full REST API, and everything you can do in the UI can be done through the API as well, which is useful for…
I already covered out-of-place patching from the web UI, but patching tasks should be automated, and clicking through the same screens for every deployment can get repetitive. Let’s do the exact same out-of-place patch of a GoldenGate Microservices Architecture deployment, this time entirely with the REST API. Every step below shows two ways to make the same call: Installing the…
While upgrading GoldenGate to 26ai for a DB2 z/OS source, I had to update the IBM Data Server Driver for ODBC and CLI (CLI Driver, in short) alongside it. Since I realized that DB2 driver know-how was rare in companies, I figured it would be worth writing a blog about the topic. In this GoldenGate upgrade, the previous driver was…
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.…
The 23.26.3.0.0 release update of GoldenGate 26ai (July 2026) ships a small but welcome usability change, listed in the New Enhancements section of the release notes: Bug 39415027: Generic – Simplified Distribution and Receiver Service Path Configuration Enhanced the Create Distribution and Receiver Service Paths experience by introducing Simple and Advanced configuration modes. The simplified view displays only the required settings by default, while…
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 quite some time to finally find a solution, I figured it was worth documenting. The client had two GoldenGate 26ai installations running on…
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 previous blog, I wrote about how to interpret the DBA_GOLDENGATE_NOT_UNIQUE view, which lists tables with no primary key or non-null unique indexes. There are two main groups of…
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, which is important when trying to automate GoldenGate management with the REST API. In fact, when using a reverse proxy with a single deployment, some endpoints are different from a…
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…
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 deployments, you will have to reconfigure the NGINX reverse proxy. If you don’t, part of your installation will not be working anymore. This is what will happen in the web…
We have been facing one issue at one of our customer where the Oracle Client connections remained opened for days blocking some avaloq JobNetz. We have been doing some tests and we could fortunately find a solution resolving the problem thanks to Oracle Database 26ai supporting now SQLNET.EXPIRE_TIME on the client side. Through this blog, I would like to share…
