#26ai

While testing EVENTACTIONS (SUSPEND) on an extract, I noticed that nothing in INFO tells you the process is suspended.

In a recent blog, I explained how instantiation filtering works. DBOPTIONS ENABLE_INSTANTIATION_FILTERING makes a replicat discard any record whose commit CSN is at or below a table's…

In my blog about the new automatic schema evolution feature in GoldenGate 26ai, I was replicating the following table from Oracle to PostgreSQL: The replicat created a PostgreSQL table from an…

In a previous blog, I noted that there might be a bug with the Maximum Input Characters setting in GoldenGate 26ai AI Service. The bug was confirmed by Oracle, so let's see what it is exactly.

For as long as I have used GoldenGate, an initial load had one prerequisite: the target tables must already exist. Data Pump takes care of it between two Oracle databases.

When automating your GoldenGate deployments, or tearing down a test environment, handling trail files is important.

For more than ten years (GoldenGate 12.2, released in 2015), GoldenGate has provided a way of performing initial load of tables with a per-table instantiation CSN.

I sometimes get asked how the new AI Service of GoldenGate 26ai works, and the best way to show it is to see it in action.

When replicating data with GoldenGate, you often want DDL changes (table alterations, new tables, dropped indexes, etc.) to follow alongside DML.

When migrating a Coordinated Replicat for a client, I faced a very specific OGG-02454 error that I wanted to share.

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.

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.

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.

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.

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.

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 -…

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.

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.

I recently wrote about NGINX reverse proxy reconfiguration after creating or deleting a deployment in GoldenGate.

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.

*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.

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

GoldenGate logs are a powerful source of information when debugging or analyzing your deployments. However, some of these logs have a rather low retention period in active deployments.

After writing blogs about Default profile updates and a bug affecting profiles in GoldenGate 26ai, I realized it would be a good idea to present a quick way to update all processes at once with the…

GoldenGate logs are a powerful source of information when troubleshooting or analyzing your deployments. However, there is at least one log file per service in the Microservices Architecture.

In GoldenGate, processes have a few options that can be managed to fit your needs.

As part of a GoldenGate setup automation, changing the Default profile of your extracts and replicats seems like a good start if you don't want to deal with custom profiles or changing each…

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.

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.

Earlier this week, Oracle Database 26ai was released, but GoldenGate 26ai is also available now !
