One of the things that kept me busy lately was experimenting with how much an Oracle XE database setup could be streamlined inside a Docker image for things like CI/CD consumption. Pretty much ever since I put together the first official build scripts for Oracle Database, people have asked for faster image pull and startup times to speed up their continuous integration tests. A lot of things have changed since then, and I’m happy that my engineering colleagues at Oracle have taken on the maintenance and further enhancements of Oracle’s official Docker build files and images, and integrated them into the internal processes.

How to install Oracle Database 18c XE on Oracle Linux 8
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 Oracle Linux 8 about nine months later. Unfortunately, installing Oracle 18c XE on Oracle 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 Oracle Linux 8. However, installing Oracle 18c XE on Oracle Linux 8 is still possible, it just requires a few more keystrokes.
tl;dr
Execute all commands as root user:
curl -OL https://download.oracle.com/otn-pub/otn_software/db-express/oracle-database-xe-18c-1.0-1.x86_64.rpmdnf install -y /bin/bash /bin/sh /etc/redhat-release bc bind-utils binutils ethtool glibc glibc-devel initscripts ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel make module-init-tools net-tools nfs-utils openssh-clients pam procps psmisc smartmontools sysstat unzip util-linux-ng xorg-x11-utils xorg-x11-xauth libnslrpm -i --nodeps oracle-database-xe-18c-1.0-1.x86_64.rpm
Oracle Database client libraries for Java now on Maven Central
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 11.2.0.4 (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:
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
