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…
When securing a MongoDB deployment, protecting sensitive data is essential. MongoDB supports encryption throughout the lifecycle of the data, with three primary types of data encryption : Among these, encryption in transit is fundamental : it protects data as it moves between your application and the database. In MongoDB, this is achieved through TLS (Transport Layer Security), which ensures that…
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…
If you’ve ever had to deal with MongoDB after years (or even decades) of working with SQL, you’ve probably realized that querying JSON documents can sometimes be painful, to say the least. In response to this, Oracle (and others) use a not-so-native adaptation of SQL to query JSON documents. And if you’ve ever had to deal with these SQL-based JSON…
Contrary to other DBMS, MongoDB self-managed deployments generate logs in a JSON format, which can be quite intimidating at first. But instead of hoping to never have to look at the logs, you can use some tools and tips to navigate them more easily and not waste time finding the information you’re looking for. Log format overview Inside /var/log/mongodb/mongod.log (or…
