At my subject of fundaments of databases we use Oracle as database (yes I hate it). I don't have a windows machine and installing all the stuff from oracle to make my exercises is pure pain to me. So this is a guide to have fun while installing it.
What we are going to use is docker to put in a container Oracle XE and we'll install Oracle SQL Developer.
You need an account in the Oracle system to download this tool.
We need to install docker. A guide for your system can be found in it's offcicial webpage. At the side nav you can find your distro.
Probably you'll need to add your user to the docker group. As described here , you can do it with
sudo usermod -a -G docker $USER
(you will need to log-out and log-in back or reboot your computer so the changes takes effect. If you used snap to install docker follow this steps )
Once you have docker installed we'll use a docker image for the Oracle XE. The one I used is this from wnameless.
What you need to do is
docker pull wnameless/oracle-xe-11g
this will download the container and then run it
docker run -d -p 49161:1521 wnameless/oracle-xe-11g
The last one will run the database listening on port 49161. As described in the container page the details for the db are
hostname: localhost port: 49161 sid: xe username: system password: oracle
This method is clean and your computer won't be filled with dependencies and things that at least I'm not going to use soon (or atleast I don't want).
To install the Oracle SQL developer I followed this guide where what you need to do is
Install java if you don't have it
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer sudo update-alternatives --config java
Download SQL Developer from the official page
sudo unzip sqldeveloper-*-no-jre.zip -d /opt/ sudo chmod +x /opt/sqldeveloper/sqldeveloper.sh
Create a symbolic link to the app
sudo ln -s /opt/sqldeveloper/sqldeveloper.sh /usr/local/bin/sqldeveloper
Edit the start script at
/opt/sqldeveloper/sqldeveloper.sh so it contains
#!/bin/bash unset -v GNOME_DESKTOP_SESSION_ID cd /opt/sqldeveloper/sqldeveloper/bin && bash sqldeveloper $*
You can create a icon in your launcher too but we aren't not using this again so.
You can stop the docker container using the
To list your containers use
After this you can configure SQL Developer to connect on port
