It has been more than two and a half years since Oracle 18c XE has been released for Linux. Since then things have changed and one of these changes was the release of Linux 8 about nine months later. Unfortunately, installing Oracle 18c XE on Linux 8 is no longer quite as straightforward as it was with Linux 7 – a simple yum command. That is because the oracle-database-preinstall-18c is not provided for Linux 8. However, installing Oracle 18c XE on Linux 8 is still possible, it just requires a few more keystrokes.
Oracle has published its Oracle Database JDBC client libraries on Maven Central. From now on you can find Oracle Database related jar files under the com.oracle.database group id. You will find all libraries from version 188.8.131.52 (e.g. ojdbc6) to 19.3.0 (e.g. ojdbc10).
Going forward, Oracle will use Maven Central as one of the primary distribution mechanisms for Oracle Database Java client libraries, meaning that you will also be able to find new versions of these libraries on Maven Central in the future.
To get the latest Oracle Database JDBC driver, use the following dependency GAV in your Maven POM file:
MuShop is a cloud-native reference showcase app of several Oracle Cloud services. The app implements an e-commerce site for cat products built as a set of Microservices. The name MuShop leans on the term Microservices: Microservices –> μ –> Mu –> Meow –> MuShop. The code itself is hosted on GitHub. There are two implementations of MuShop, one is the Basic Deployment which runs entirely on the Oracle Cloud Free Tier. The other one is the Complete Deployment which is deployed on a Kubernetes cluster such as Oracle Kubernetes Engine (OKE). In this post, I will cover the Basic Deployment of MuShop.
