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.

1. Prerequisite

First, Java 8 (also known as Java 1.8) must be installed, which you can download here: http://www.java.com.

Mac OS User see here

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).

Remarks:

  • If you want to use the update feature, do not install Odysseus in a shared folder.
  • Under windows: Do not use folder "program files".
  • Important: Do not use an existing directory, e.g. from an older Odysseus installation! If you want to update, see How to update Odysseus.

After unpacking, you may have something like the following:

4. Start Odysseus

Run "studio.exe" to start Odysseus.

Remark:

  • As studio is an Eclipse based application you can raise the memory the same way:
  • If an error occurs at start, try to execute java -version on a console to see if the right Java version is installed and reachable.

In studio.ini:

-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417
-console
-clean
-nl
en
-data
@noDefault
-vmargs
-Xms1000M
-Xmx1000M
-Dsysredirect=true
-Declipse.p2.mirrors=false
-Declipse.log.level=ERROR

change Xms and Xmx to the needed values. Default is 1000M.

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.

6. Login

Next, Odysseus asks you for a user and a password. The default user is "System" with password "manager". You can also check "Login automatically" so that username and password is saved and used automatically at the next start so you don't have to type in your login data again. In some cases there may be a field "Tenant". For most cases this field should be empty.

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.

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:

A. Hints if installation/start fails

  • Java 1.7 (or sometimes called Java 7) has to be used. Although Java 1.7 was installed, it may happen that Java 1.6 is still used. Therefore, check if 1.7 is used. Check also, if JAVA_HOME is set correctly.
    • On windows, you can check the version by open the command line to tool (go on "start", and "run" and enter "cmd", then press OK. In the command line enter "java -version" and hit enter. You should see some lines beginning with "java version "1.7.XXXX". if command is not found or another version is shown, check your Java installation.
    • On MacOS X, you may look at "B. Mac OS X and Java 1.7" in the next section.


  • Be sure you downloaded the x86_64 version if you have a 64 bit operating system or the x86 version if you have a 32 bit operating system.


B. Mac OS

To run Odysseus from the pre-compiled packages available to download you have to do the following steps.

  1. Download and install Java 8 from Oracle (/usr/libexec/java_home -t BundledApp shut output a Java 8 version)
  2. Download Odysseus from our homepage
  3. Open the terminal (e.g. with spotlight)
  4. Direct to the odysseus-folder, navigate to  ../Contents/Eclipse/
  5. Run the following command:
Run Odysseus under MacOS
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.

Debian
sudo aptitude install default-jre

Download and unzip the Odysseus package to your local bin folder

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


Add the Odysseus folder to your PATH variable

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:

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

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:

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 )

wget http://odysseus.informatik.uni-oldenburg.de/download/products/server/startOdysseusServer
chmod +x startOdysseusServer
#!/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

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:

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:

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)

for server
cd
./startOdysseusServer
For peer
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:

(http://www.forum-raspberrypi.de/Thread-tutorial-automatisches-starten-von-scripte-programme-autostart)

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
