Real-time data replication with Oracle GoldenGate: how to configure it, keep it running, use it for migrations and connect Oracle with other databases.
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 see what changed from a GoldenGate administrator perspective. Installation, setup and patching As you may know, GoldenGate 26ai is just a patch of the existing 23ai…
With GoldenGate 19c and 21c Premier Support coming to an end in April 2026, time is ticking for many clients with old installations of GoldenGate. Fortunately, Oracle provides a Migration utility (patch 37274898 / KB100447 in MOS) that is designed to migrate your old Classic Architecture to a brand new Microservices Architecture in GoldenGate 23ai. As mentioned in a previous…
Classic Extracts have been deprecated in GoldenGate 19c and shouldn’t be part of your GoldenGate replications for a long time now. Yet, some customers still have them, and with GoldenGate 19c support coming to an end in a few months, it is high time you upgrade to GoldenGate 23ai. However, GoldenGate 23ai doesn’t support classic extract, and the migration utility…
At the moment, three versions of GoldenGate are still under Premier Support, but this will very soon change, with GoldenGate 19c and 21c coming out of Premier Support in April this year ! I give below the official Oracle support end dates, as per 2026. GoldenGate Release Release date End of Premier Support End of Extended Support 23ai May 2024…
Another day, another not-so-documented GoldenGate error, this time about the OGG-10556 error, which I had when setting up replication on a new GoldenGate installation. After making changes from the web UI in an extract, I ended with the following error when starting it: Since the exact configuration is not relevant here, I will not add it to the blog. After…
If you start using the GoldenGate web UI after installing it, you might end up thinking that extending the session timeout would be nice. Since there is no clear Oracle documentation on that matter, here are multiple ways of doing it. Modifying the configuration files: quick but with downtime The first way of doing it is to modify the deploymentConfiguration.dat…
Very quick piece of blog today to tackle the OGG-00423 error. There is not much information online on the matter, and the official Oracle documentation doesn’t help. If you ever stumble upon an OGG-00423 error when setting up GoldenGate replication, remember that it’s most certainly related to grants given to the GoldenGate user. An example of the error is given…
I was recently setting up GoldenGate for a client when I was struck by a ORA-44001 error. I definitely wasn’t the first one to come across this while playing with grants on GoldenGate users, but nowhere could I find the exact reason for the issue. Not a single question or comment on that matter offered a solution. The problem occurs…
You might have an existing unsecure GoldenGate installation that you would like to secure, whether it’s for security reasons or because you would like to dissociate the installation and its securing process. After searching everywhere in the Oracle documentation for how to proceed, I decided to try, investigate and eventually even asked Oracle directly. Here is the answer. For a…
26ai update: This article was originally written for 23ai. But not much changes when setting up GoldenGate 26ai. Just adapt the responseFileVersion when doing the silent installation, and that’s it ! As instructed in this other blog, use oracle.install.responseFileVersion=/oracle/install/rspfmt_ogginstall_response_schema_v26_1_0 Automating Oracle installations can sometimes be daunting, given the long list of parameters available. We’ll compare both graphic and silent installations…
