AVO Prototype - SWG Download Page
|
Scheduled server downtimes: none
To AVO team members: Add notifications here and remove obsolete ones.
SWG members are encouraged to send feedback and may request support for installing and running the demonstrator via email to:
This prototype suite is a testbed and demonstrator of new technologies and methodologies. It is not considered to serve as a replacement for existing archive interfaces and data analysis tools.
Installation
- If the system requirements are met click on automatic installation to start up the InstallAnywhere Java Applet, follow the instructions and return to this page. If, for some reason the automatic installation fails then use the manual procedure - otherwise skip the next bullet.
- If the automatic procedure does not work then download AVO.jar and drop it into the installation directory of your choice.
Installation done.
Portal
To fully run the demos you will need to log into the Avo Demo 2005 portal at http://vo.eso.org:8080/astrogrid-portal/. If you do not yet have a username then you need to complete the portal registration form.
Running Aladin for AVO
Depending on your local system choose one of below options:
- Windows: invoke Aladin from Start menu
- Unix: change to the installation directory and enter
./AVO
- In case the automatic installation does not succeed change to the directory where AVO.jar resides and enter on the command prompt (requires Java V1.4.1+):
java -Djava.security.manager -Djava.security.policy=java.policy -Xmx500m -jar AVO.jar
Running Aladin for AVO via HTTP proxy
If your site uses an HTTP proxy, the proxy host and port number needs to be specified. If unsure try without a proxy configuration first.
If needed contact the local sysadmin to learn about the correct settings at your site or look at your web browser configuration to clone the HTTP proxy values from there. Unless it is configured properly there is no Internet access in a proxy environment.
- If the prototype was installed through InstallAnywhere, change to the installation directory and add the following line to the end of the AVO.lax configuration file:
lax.nl.java.option.additional=-Dhttp.proxyHost=proxyhost -Dhttp.proxyPort=portNumber
Replace proxyhost by either the proxy hostname or by its IP number ; replace portNumber by the proxy port number.
Then run the prototype as described above.
- When launching the prototype from the command line, enter on the command prompt:
java -Dhttp.proxyHost=proxyhost -Dhttp.proxyPort=portNumber \
-Djava.security.manager -Djava.security.policy=java.policy -Xmx500m -jar AVO.jar
Replace proxyhost by either the proxy hostname or by its IP number ; replace portNumber by the proxy port number.

System Requirements
| Disk Space | 50 MB S/W and 200+ MB local data. |
|---|
| Memory | 512 MB minimum, 1+ GB recommended (to reproduce demo 2005).
Startup parameter -Xmx1000m allocates 1000MB, however, it only works if this amount of memory is physically installed. |
|---|
| Java | JRE 1.4.1+; it comes as part of the automatic installation.
The VOSpec plug-in uses the java SecurityManager to open socket connections. |
|---|
| Web Browser | The automatic installer requires that Java applets are supported and enabled. In case the InstallAnywhere applet on the download page does not start up there is a workaround: click on the download link for your operating system and retrieve the package install.bin and put it in a scratch directory. Then proceed with the OS specific instructions. |
|---|
| Operating System | The automatic installer works for a limited number of systems only. If the list on the installer page is lacking the name of your operating system then a manual installation (bullet 2) is needed.
The AVO prototype itself is a Java application which - in principal - runs on any system that has got a Java Runtime Environment V1.4.1+. Tests, however, were only done for a number of Linux flavors and Windows XP. Some people used the tool on Solaris and MacOSX, but there is no guarantee that all features work. |

2nd Year Demo
 |
The AVO 2nd year demonstration was held at European Southern Observatory on Tuesday Jan 27, 2004. At this event the progress of the AVO project has been demonstrated to the AVO Science Working Group by means of scientific scenarios. A highlight was the inclusion of spectroscopic data.
|
1st Year Demo
 |
The AVO 1st year demonstration was held at Jodrell Bank Observatory on Monday Jan. 20, 2003. At this event the prototype was introduced via presentations and by live demo of the prototype capabilities and functionality.
