ATTENTION: There could be cases, where Odysseus starts with an error like "java.lang.IllegalArgumentException: no such operator: SHUFFLEFRAGMENT." (especially in the first starts) or "java.lang.ArrayIndexOutOfBoundsException: Index 104 out of bounds for length 104". We are working on this problem. Please try to restart!
This is a short tutorial that shows how to install Odysseus and how to setup the first time. This tutorial is for persons who just want to use Odysseus for data stream management. For those, who want to develop with Odysseus (e.g. create new operators or extend functionalities), may have a look at Development with Odysseus, which introduces how to import Odysseus into Eclipse.
There are some differences, when using Odysseus on MacOS. See below
For problems with Dark mode see below.
1. Prerequisite
First, Java 8 (also known as Java 1.8) 17 must be installed, which you can download here: http://www.java.com.
2. Download Odysseus
Go to Odysseus Website to the Download section. You can choose between a stable version, which is stable but may not be the latest version, or you choose a nightly build which consits the latest fixes and is built each day at midnight. Choose the Version for your operating system in a 64 or 32 bit version. In our case, we have a 64 bit Windows 7 so that we choose Windowx x86 64 bit. Download the archive.
3. Unzip
Next, you have to unzip the archive. There is no installer nor a dedicated installation directory. Thus, you can choose a destination of your choice (In some cases, Odysseus does not behave correctly, if the installation path is to long. In this case try to install Odysseus to another location).
...
change Xms and Xmx to the needed values. Default is 1000M.
Remark: On MacOS you cannot start the Odysseus Studio.app. You will need to open the app (Show package content) and in the Contents section, move to folder MacOS and open studio. The app is not signed, so you need to relax your security configuration when downloading with Safari. When using Chrome for download, there seems to be no restriction.
If this does not work: You should go to the content folder via termial and change to folder MacOS. If studio has not execution rights you can use: chmod +x studio and run ./studio afterwards. Now Odysseus Studio should start.
5. Choose Workspace
At the first start, you have to choose a workspace. This workspace is a directory where all Odysseus projects will be stored.You can also check the "Use this as the default.." option so that this dialog will not pop up at the next start of Odysseus.
...
If you are using the client version of studio, the WebService tab must contain information about the Odysseus Server:
After that, Odysseus Studio starts, so you should the the interface:
That's all.
Dark Mode
The default dark mode is not very good suited for Odysseus. We provide special themes (OdysseusDark and OdysseusLight) for this. Just open Window/Preferences and navigate to Appearance:
7. Next steps
You now can use Odysseus. Now, you can, for example, make yourself familiar with Odysseus Studio or you may create or import projects. For further steps, you may have a look at these pages:
- Odysseus Studio introduces the interface, views and commands
- Run Nexmark Example shows a tutorial how to run an example that is based on the Nexmark benchmark, including a data generator.
- Hands on Data Stream Processing shows different tutorials how Odysseus can be used in different projects - including special hardware
A. Hints if installation/start fails
...
On MacOS X, you may look at "B. Mac OS X and Java 1.7" in the next section.
...
To run Odysseus from the pre-compiled packages available to download you have to do the following steps.
- Download and install Java 8 from Oracle (/usr/libexec/java_home -t BundledApp shut output a Java 8 version)
- Download Odysseus from our homepage
- Open the terminal (e.g. with spotlight)
- Direct to the odysseus-folder, navigate to ../Contents/Eclipse/
- Run the following command:
| Code Block | ||
|---|---|---|
| ||
java -XstartOnFirstThread -Xmx500M -Xms500M -Declipse.p2.mirrors=false -jar plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar --launcher.library org.eclipse.equinox.launcher_1.3.100.v20150511-1540 -console -nl en -debug -data @noDefault -showsplash de.uniol.inf.is.odysseus.rcp.base -Dorg.eclipse.swt.internal.carbon.smallFonts -clean |
C. Installation under Linux
Odysseus should be installed for a single user. The user that starts the server process must have all rights to the installtion directory, else no new features can be installed and no features can be updated.
To run Odysseus you need a Java runtime environment in version 7.
| Code Block | ||||
|---|---|---|---|---|
| ||||
sudo aptitude install default-jre
|
Download and unzip the Odysseus package to your local bin folder
| Code Block | ||
|---|---|---|
| ||
mkdir –p ~/bin
wget –c http://odysseus.offis.uni-oldenburg.de/download/studio/stable/serverandstudio/odysseus.serverandstudio.gtk.linux.x86_64.zip -O ~/bin/odysseus.zip
unzip odysseus.zip –d ~/bin |
...
| Code Block | ||
|---|---|---|
| ||
export PATH=~/bin/odysseus:$PATH
|
D. Running Odysseus Server on Raspberry Pi, Beagleboard Black Rev C
The Odysseus server component works on a Raspberry Pi. Simple install a recent raspian first.
You should use a distinct user for odysseus.
After that, you should update/upgrade the system and install JavaJRE:
| Code Block |
|---|
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install openjdk-7-jre |
Tip: With the console-command raspi-config you can configure your RaspberryPi/BananiPi further (e.g. keyboard layout)
The following script will download and install Odysseus as a server-component
| Code Block |
|---|
wget http://odysseus.offis.uni-oldenburg.de/download/products/server/lastBuild/odysseus.server.gtk.linux.x86.zip
unzip odysseus.server.gtk.linux.x86.zip
|
Alternatively, if multiple Odysseus-Instances should be connected (Peer-to-Peer-Network of RaspberryPi), you should download the Peer-Version of Odysseus:
| Code Block |
|---|
wget http://odysseus.offis.uni-oldenburg.de/download/products/peer/lastBuild/odysseus.peer.gtk.linux.x86.zip
unzip odysseus.peer.gtk.linux.x86.zip
|
The following script will execute Odysseus (Server-Version) with respect to restarts due to possible future updates (downloadable: http://odysseus.informatik.uni-oldenburg.de/download/products/server/startOdysseusServer )
| Code Block | ||
|---|---|---|
| ||
wget http://odysseus.informatik.uni-oldenburg.de/download/products/server/startOdysseusServer
chmod +x startOdysseusServer |
| Code Block |
|---|
#!/bin/bash
cd odysseus.server.gtk.linux.x86
while true; do
java -Xmx500M -Xms500M -Declipse.p2.mirrors=false -jar plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar -console -debug -data @noDefault
if [ "$?" != "23" ]; then
break
fi
done
|
Attention: If you downloaded and installed the Peer-Version of Odysseus, you have to replace "server" with "peer" in the 3rd line (or download it from http://odysseus.informatik.uni-oldenburg.de/download/products/peer/startOdysseus).
Attention: The script-file must be made executable with chmod +x startOdysseus
| Code Block |
|---|
wget http://odysseus.informatik.uni-oldenburg.de/download/products/peer/startOdysseus
chmod +x startOdysseus |
For the standard Beagle board "unzip" and "java" must be installed:
| Code Block | ||
|---|---|---|
| ||
apt-get update
apt-get install unzip
apt-get install openjdk-7-jre
// If multiple java versions are installed: choose the jdk to use. Must be at least java 7
update-alternatives --config java |
Start same as above the raspberry.
Further devices tested:
- Cubiboard use e.g. http://www.igorpecovnik.com/2013/12/24/cubietruck-debian-wheezy-sd-card-image/
- Cubiboard 3 (Cubietrack), Image use e.g. http://www.igorpecovnik.com/2013/12/24/cubietruck-debian-wheezy-sd-card-image/
- Banana Pi
For a "quick and dirty" way to start Odysseus automatically on startup, you have to edit the file /etc/inittab according to these instructions: http://elinux.org/RPi_Debian_Auto_Login
At the following to the end of the file .bashrc of the user (e.g., /home/pi/.bashrc)
| Code Block | ||
|---|---|---|
| ||
cd
./startOdysseusServer |
| Code Block | ||
|---|---|---|
| ||
cd
./startOdysseus |
Remark: For BeagleBone, autologin has to be activated like here described
http://embedded.von-kannen.net/2014/06/28/how-to-enable-autologin-debian/
Alternative:
Create a file odysseus in folder /etc/init.d/, give execute rights and replace DAEMON_PATH with your installation directoy, replace DAEMON with startOdysseusServer (startOdysseus in Peer)
/etc/init.d/odysseus start
/etc/init.d/odysseus stop
