Oracle XE & APEX
The goal of the OXAR (pronounced "Oscar") project is to make it easy for developers to quickly build and/or launch a fully functional instance of Oracle XE and APEX. The scripts provided in this project handle the automatic build.
Note: Currently this build lacks a backup script. It is recommended to do your own backup
If you need additional help, there is a How-To video for this installation which walks you through the entire process.
Current Software Versions
|SQLcl||4.2.0||Command line SQL|
|APEX||18.2||Currently supports APEX 18.x, 5.x and APEX 4.x releases. Just reference the appropriate file in
|APEX Office Print||3.0||Currently only supports 5.x. Disable the option to install this add-on if you are installing versions earlier or later than 5.x|
|oracledb||latest||Node.js driver for Oracle|
|pm2||latest||Process manager for Node.js apps|
This script currently works on the following Linux distributions
|See #198 for more information|
|See #198 for more information|
|Native Build||This is the default option and assumes thats you will be running this script on the machine that it will be installed on. Common uses of this is to run in a VM or cloud machine.|
|Vagrant||Vagrant is a tool for building development environments. Some additional configuration is required when running this script with Vagrant. These changes are noted in the documentation|
|Prebuilt Images||Due to licensing issues, we can not provide a prebuilt image or appliance. As such you will need to manually build the VM yourself with the provided scripts.
If you are using Amazon AWS EC2, please be sure to follow the configuration steps listed here.
You can build your own VM with the following instructions.
#Ensure user is currently root if [ "$(whoami)" != "root" ]; then sudo -i fi cd /tmp #Install Git if [ -n "$(command -v yum)" ]; then #RHEL type OS yum install git -y else #Debian type OS apt-get install git-core fi git clone https://github.com/OraOpenSource/oxar.git cd oxar
Run the following on your host machine (you will need
git installed on your host machine):
git clone https://github.com/OraOpenSource/oxar.git cd oxar
Regardless of whether you're doing a native or Vagrant based build, you will need to modify the
config.properties file prior to running the installation script. At a minimum, you will need to replace the CHANGME tokens to point to the appropriate files. Read below for help on modifying this file. If doing a Vagrant install, you can modify
config.properties using your local text editor.
#Hints for vi: #Type:<esc key>?CHANGEME to search for CHANGEME #Once done modifying an entry, hit <esc> and type: n to search for next entry vi config.properties
Due to licensing requirements, you must download the Oracle installation files and modify the following parameters in the config file with the location of these files.
||Download This is an optional file|
These can be references to files on a web server or to the location on the server. Some examples:
#Assuming the file resided on myserver.com OOS_ORACLE_FILE_URL=http://myserver.com/oracle-database-xe-18c-1.0-1.x86_64.rpm #Assuming the file is placed in the /tmp folder on the machine OOS_ORACLE_FILE_URL=file:///tmp/oracle-database-xe-18c-1.0-1.x86_64.rpm
You can copy files from your local machine to the remote server easily using
scp oracle-database-xe-18c-1.0-1.x86_64.rpm firstname.lastname@example.org:/tmp
To assist getting your Oracle installation files configured for OXAR one approach is to use Dropbox. Once you have downloaded the install files, store them on dropbox and then reference them using the Shared Link feature. Note that you need to change the
...?dl=0 to a
...?dl=1 at the end of the file. For copyright purposes you should only use these links for your OXAR install and not share them publicly.
Instead of having to use
vi to edit the file you can use
sed to find and replace. An example is as follows: (Note: the escaping of forward slashes (
/) in the URL)
sed -i 's/OOS_ORACLE_FILE_URL=CHANGEME/OOS_ORACLE_FILE_URL=https:\/\/www.dropbox.com\/s\/SHAREDLINKCODE\/oracle-database-xe-18c-1.0-1.x86_64.rpm?dl=1/g' config.properties sed -i 's/OOS_APEX_FILE_URL=CHANGEME/OOS_APEX_FILE_URL=https:\/\/www.dropbox.com\/s\/SHAREDLINKCODE\/apex_5.0.3_en.zip?dl=1/g' config.properties sed -i 's/OOS_ORDS_FILE_URL=CHANGEME/OOS_ORDS_FILE_URL=https:\/\/www.dropbox.com\/s\/SHAREDLINKCODE\/ords.126.96.36.1994.08.40.zip?dl=1/g' config.properties sed -i 's/OOS_SQLCL_FILE_URL=/OOS_SQLCL_FILE_URL=https:\/\/www.dropbox.com\/s\/SHAREDLINKCODE\/sqlcl-188.8.131.52.049.0843-no-jre.zip?dl=1/g' config.properties
Vagrant automatically maps your current folder to
/vagrant on its VM. You can copy your files to the subdirectory
oraclexe_apex (on your host machine) and reference them with
files subdirectory has been added to .gitignore to exclude the installation files from version control.
You can optionally chose which modules you want installed. This install supports the following optional modules which can be modified in
||Y||Install Oracle XE|
||Y||Install's APEX and all of it's components (Tomcat, ORDS, etc)|
There are additional APEX configurations that you may want to make in the
scripts/apex_config.sql file. You can run them later on or manually configure them in the APEX admin account.
By default you don't need to configure anything, however you may want to modify various things about your Vagrant machine. To do so, modify
To build the server run the following commands. It is very important that you run it starting from the same folder that it resides in.
OXAR now supports 3rd party add-ons to be included into OXAR. Current list of add-ons:
|APEX Office Print||Flexible print server for Oracle Application Express (APEX) to generate your Office and PDF-documents in no time and effort - we make printing easy.|
Securing the Server
If you use OXAR in a production instance or is available on the internet it is recommended that you lock down certain features. Review our Securing System document.
How to connect
Oracle / SQL*Plus / SQLcl
There are many different ways to connect to Oracle with SQL*Plus. The How to Connect to Oracle document covers them.
||User you can use to develop with right away|
To start/stop/restart Oracle run the following commands:
/etc/init.d/oracle-xe start /etc/init.d/oracle-xe stop /etc/init.d/oracle-xe restart
To connect to APEX go to
https://<server_name>/ and it will direct you to the APEX login page.
||Workspace administrator account|
||You can start developing on this account. It is linked to OOS_USER schema|
APEX Web Listener
This project uses Node4ORDS as a web listener. The Node4ORDS project provides the ability to serve static content and will provide additional web server functionality. Please read its documentation for more information.
Node4ORDS is installed in
/opt/node4ords. It can be controlled by:
pm2 start node4ords --watch pm2 stop node4ords # For older versions of OXAR # systemctl start node4ords # systemctl stop node4ords
Static content can be put in
/var/www/public/ and referenced by
http://<server_name>/public/<filepath>. More information about the web listener configuration can be found at the Node4ORDS project page.
OXAR now supports SSL out of the box with an unsigned certificate. For configurations options and how to obtained a signed certificate read the SSL docs
Oracle REST Data Services (ORDS) allows web servers (such as Tomcat) to connect serve up APEX pages. It is located in
The APEX images are stored in
Since ORDS is a module that is added to Tomcat, there is no direct stop/stop commands for it. To restart ORDS, restart Tomcat.
This server uses Apache Tomcat as the web container for ORDS. By default, the firewall restricts public access to the Tomcat server directly. Note: To access APEX, you do not need to reference Tomcat directly (via port 8080 by default). Connecting to Tomcat is only required for additional debugging or configuration.
If you do want to make it accessible run:
service firewalld start firewall-cmd --zone=public --add-service=tomcat
You can then access Tomcat Manager via
http://<server_name>:8080/manager or Application Express via
By default the admin account is tomcat/oracle
To disable Tomcat firewall access run: note: if you don't disable it, the next time the server is rebooted it will be disabled.
firewall-cmd --zone=public --remove-service=tomcat
Tomcat is located in
/usr/share/tomcat/. Tomcat can be controlled by:
systemctl stop tomcat@oxar systemctl start tomcat@oxar
Shell Access for Vagrant
For VM created by Vagrant, the following user accounts can be used to access the VMs via SSH:
The default port settings are as follows:
|1521||Oracle SQL connection||Optional (default: No)|
|8080||Tomcat||Optional (default: No)|
|8081||PL/SQL Gateway||No||Disabled by default|
Optional ports can be configured in
config.properties in the
FIREWALL section. If you want to modify the firewall settings after running the build script, open
scripts/firewalld.sh and look for examples on how to open (both temporarily and permanently).
To start/stop the Firewall:
systemctl start firewalld systemctl stop firewalld
Vagrant Port Mapping
The following ports are mapped to the host and can be configured in Vagrantfile:
|22||50022||SSH||An additional port may be assigned by Vagrant.|
|1521||50521||Oracle SQL connection||The port is mapped but usable only if permitted by firewall rules **.|
** See Port Configurations.
OS Utility Scripts
When setting up a new server their are some common things that you may want to do such as creating a new user, disabling root SSH access, etc. Though these tasks are outside the goal of this project, we've created a new folder
utils/os to store some of these common scripts which may help when setting up a new server.
Oracle Utility Scripts
This install uses some common Oracle scripts that may be useful to run at a later time. For example, the
create_user.sql, creates a user with all the necessary privileges to start using. For more info, go to the
Editing server files locally
To make it easier to edit files on the server (and avoid using vi), Remote-Atom (ratom) is installed by default. This requires that you have the Atom text editor on your desktop and have installed the ratom.
When you connect to the server use the following connection string:
ssh -R 52698:localhost:52698 <username>@<server_name_or_ip_address>
Note: Port 52698 is the default port and can be changed in the plugins settings in Atom
Once you're connected, to edit a file locally, simply type:
The file will then appear in your Atom editor.
