This page briefly describes how to set up a DSpace test instance that runs with the Oracle DB. Note that this method is not suitable for production environments; rather it is intended for committers and other community members who don't normally have access to an Oracle database but wish to test patches and other code relevant to DSpace with Oracle.
You will need Oracle VM Virtualbox. Binaries for all major operating sytems are available free of charge from https://www.virtualbox.org/.
Download and import virtual machine image
Oracle makes available virtual machine images for developers. You need to register for a free Oracle Tech Network account and agree to various license agreements.
Download the Database App Development VM image from http://www.oracle.com/technetwork/database/enterprise-edition/databaseappdev-vm-161299.html and import it into virtualbox as a new appliance. I increased the memory for the virtual machine to 3 GB.
Initialize virtual machine
Start the virtual machine (as per instructions on the download page, use username+password oracle).
Set up the database
Open a terminal and log on to the database as a superuser (password: oracle):
Then create the database user and database (which is referred to as a "schema" in oracle terms): (Thanks to Hardy Pottinger for the SQL statements.)
Run DSpace Remotely OR Install DSpace on Virtual Machine
One you have the (empty) database created on this Oracle Virtual Machine, you have two options (choose one):
- You can run DSpace remotely (e.g. on your host machine), and just point it at this Oracle Virtual Machine (see: "Run DSpace Remotely")
- OR, you can install DSpace directly on this Oracle Virtual Machine and run it there (see: "Install DSpace on Virtual Machine")
If you elect to run DSpace remotely, the following aliases may be helpful to you, if you are using a Unix or Linux-based OS for your host machine.
The ostart alias will start up your oracle database, the oshut alias will shut it down very quickly, essentially pausing your server in the state it is in.
If you are using Vagrant-DSpace as your development environment, you will want to create a new vagrant.properties file. Name it something else, vagrant-oracle.properties works. Here are the settings you'll want to use for the database.
Things to note: you will want to comment out the Postgres configuration, and change the db.name to oracle. And you'll need to install the Oracle driver as per the usual.
The remainder of this how-to assumes that you wish to run a test DSpace instance in the virtual machine. If you prefer to run DSpace on the host machine instead, you could instead set up port forwarding for the Virtualbox appliance and use only the database in the virtual machine. In that case, skip the rest of this how-to.
Run DSpace Remotely (recommended)
If you chose this option, we are assuming you have DSpace installed elsewhere (e.g. on your host machine).
- First setup port forwarding for this Oracle Virtual Machine
- Open up your VirtualBox Manager
- Select the Oracle Virtual Machine, and click the "Settings" button (at the top, looks like a gear)
- Go to the "Network" settings, and click "Port Forwarding" button at the bottom
- By default, you should already see a port forwarding rule for "sqlnet" which looks like this. You can modify that if you wish, or leave as-is.
- sqlnet | TCP | Host Port: 1521 | Guest Port:1521
- You also may wish to add a new rule for SSH access (port 22), something like this:
- SSH | TCP | Host Port: 2200 | Guest Port: 22
- Test out your SSH access. From your host machine type:
ssh -p 2200 oracle@localhost(password: oracle)
- Login as the "dspace" user:
- On the machine where your DSpace is installed, you will need to do the following:
- Download the latest Oracle OJDBC JAR from http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html
Install this JAR into your local Maven cache (~/.m2):
Update your build.properties database settings to refer to this Oracle database on the virtual machine. Pay close attention to the port, if you changed the default port forwarding rule for "sqlnet":
Rebuild your DSpace with Oracle enabled:
At this point, your DSpace should be "connected" with the Oracle Virtual Machine. You should be able to simply do a "fresh_install" of DSpace, and startup your Tomcat to see it in action
You can also now login as the "dspace" database owner/user by simply SSHing into the Oracle Virtual Machine as follows:
Install DSpace on Oracle Virtual Machine
Install build tools
The virtual machine image comes with ant preinstalled, but the version is too old (1.6.4). There is no maven installation on the machine.
Download the binary distributions of the ant and maven from http://ant.apache.org/ and http://maven.apache.org and install them on the virtual machine, for example into ~/software. I symlinked the directories created by unpacking the tarballs so that I had ant in ~/software/ant and maven in ~/software/maven, so I'll use those paths in the rest of the instructions. You'll need to add ~/software/ant/bin and ~/software/maven/bin to the beginning of your PATH variable; eg put at the end of ~/.bash_profile:
You will need to log out and back in to make these settings apply, or type
If ant -version shows that you are still running the old version of ant, try also adding this to ~/.bash_profile:
Build + install DSpace
Download the source distribution of DSpace (https://github.com/DSpace/DSpace/archive/dspace-3.0.tar.gz for DSpace 3.0) and unpack the tarball. I then renamed the directory to ~/dspace-src.
Create the directory ~/dspace.
Follow the standard DSpace 3.x installation instructions to configure, build and install DSpace. Change your build.properties file (leave everything else as-is):
I also disabled the mail server in ~/dspace-src/dspace/config/dspace.cfg.
It may not be readily apparent from the example config lines above, but the SID used by the Oracle VirtualBox image is "orcl".
Tomcat isn't installed on the virtual machine. Download the binary distribution from http://tomcat.apache.org/; I used Tomcat 6 and installed it into ~/software/tomcat by unpacking the downloaded tarball and symlinking the directory. You will also need to copy the ojdbc6.jar file that you downloaded in the previous step into ~/software/tomcat/lib.
Use your preferred method to link up Tomcat with the DSpace webapps that you need. I placed symlinks to ~/dspace/webapps/xmlui and ~/dspace/webapps/solr into ~/software/tomcat/webapps after first removing everything from ~/software/tomcat/webapps.
Start tomcat by running
cd ~/software/tomcat && ./bin/startup.sh
and your DSpace+Oracle instance should come up at http://localhost:8080/xmlui/.
