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 GoldenGate 26ai, a customer complained that he was seeing a lot of the following error in the ggserr.log file of a GoldenGate deployment (I replaced the names for the purpose…
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 Microservices Architecture, you should definitely update your plug-in and rediscover all targets. Let’s see how to do all that here. In this blog, I will use the latest version of the Enterprise…
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. They might then not even be useful for debugging if you send them to your dbi consultants or the Oracle support for analysis. So how can you increase GoldenGate log retention ?…
Recently, I wrote about deleting a GoldenGate deployment with the REST API, and when investigating this issue, I remembered a limitation of the configuration assistant, which I wanted to talk about. For more information about deployment removal with the configuration assistant, you can read a blog I wrote on the topic (for 23ai, but nothing changed in that regard in…
In this blog, I will explain what needs to be done when registering GoldenGate targets behind NGINX reverse proxy in the Enterprise Manager. More specifically, we will see how to avoid the EM-90000 error related to an SSLHandshakeException. If you are upgrading to GoldenGate 26ai and migrating from Classic to Microservices Architecture, you must re-discover GoldenGate targets in the Enterprise…
Recently, I was asked how to recreate a GoldenGate deployment if the password for the Security user (the first user created with the deployment) was lost. This is an interesting question that I figured was worth writing about. As a reminder, you have two main ways of creating and deleting deployments in GoldenGate: I already covered the creation and removal…
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 REST API. Because even if you set a new profile as default with the {“isDefault”: true} flag, previously created extracts and replicats will not…
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. This means that for a GoldenGate setup with multiple deployments, you can quickly have tens of log files to search for information. In that context, knowing where to look is important, especially…
Setting up a distribution path is an important step when connecting two GoldenGate deployments. However, there are so many connection options that it’s hard to know how to proceed. In this blog, I will present the way to connect two deployments secured through NGINX. Here are the prerequisites before attempting the distribution path creation: In my environment, I have the…
After working on a GoldenGate deployment recently, I felt that the OGG-30007 error would be worth writing about. This error happens when registering certificates in GoldenGate. Whether you do it from the web UI or with the REST API, this GoldenGate error is detailed as such: This error occurs because GoldenGate expects exactly one PEM object per import, while a…
In GoldenGate, processes have a few options that can be managed to fit your needs. When creating an extract, for instance, you can act on the following parameters: In the web UI, an extract profile can be customized during the third step of an extract creation called Managed Options. Here, you can choose to use the default profile, a user-defined…
Your GoldenGate certificates should be granted by a trusted Certificate Authority, which normally handles the monitoring of certificates. However, if you don’t want your future you, or a colleague, to spend too much time debugging which certificate should be renewed, you could monitor your certificates. In this blog, I will present a way to do this with the REST API.…
