Oracle Database client libraries for Java now on Maven Central

Oracle has published its Oracle Database JDBC client libraries on Maven Central. From Apache Mavennow 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>
    <artifactId>ojdbc10</artifactId>
    <version>19.3.0.0</version>
</dependency>

How to enable auto start/shutdown for Oracle Database 18c Express Edition on Linux

Oracle Database 18c Express Edition can be enabled for automatic startup and shutdown with the Linux operating system. This will not only allow you not to worry about starting and stopping the database but it will also ensure that the database is properly shutdown before the machine is powered off. Enabling auto startup/shutdown is done via two simple commands:

  1. systemctl daemon-reload
  2. systemctl enable oracle-xe-18c

These commands will have to be executed either via the root user or with root privileges:

[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl enable oracle-xe-18c
oracle-xe-18c.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig oracle-xe-18c on

For more information about starting and stopping Oracle Database XE, have a look at the documentation.
