Check your ulimit values - you really may have run out of file handles or similar.

Jay,

Is this a Linux server machine? The Design Manager server needs a display to be able to render the diagrams (has to do with the Java classes). It doesn't need a physical display though. On my Linux server I can run it using the following commands:

export DISPLAY=localhost:38.0
Xvfb :38 -screen 0 1024x768x24 -ac &
./server.startup

When we try to view the model diagrams of the imported models in the RSADM server using the web ui, we are getting an error which says "Unable to load diagram".

We already went through the following forum post and increased the Open files limit and set the DISPLAY variable in our Linux server. However this did not resolve the problem.

https://jazz.net/forums/viewtopic.php?p=60203)

This is the error that we see in our RSADM server log. Could you please help us resolve this error.

Thanks.

Looks like a defect to me. Please create a defect against DM Server and provide the server log files (dm.log at the very least) Which version of DM is that?
Can you also roughly estimate the number of diagrams the server had generated successfully?Diagram files are in the server work folder .Think it's <installtion>/server/tomcat/work/.metadata/.plugins/com.ibm.xtools.rmps.core Which format are diagram image files? PNG?
If you reboot the server machine, clean up the diagram cache folder, how soon do you start getting out of handles problem? Do you just open diagrams in the web browser?

Perhaps there is an issue with disposing platform resources on Linux...
I doubt you run out of handles because of diagrams generaton. If image format for diagrams is default: PNG, then image generation uses AWT only, which means there won't be any platform resources.

Cheers,
Alex

We are using RDM 3.0. I will open a defect and attach the dm.log file to the defect.

This is a newly setup server and we are not able to browse any of the model diagrams since we imported the first model. We even tried this with the sample model (JKE Banking) but even there we are not able to browse the diagrams. Also I could not find a .metadata folder under the /opt/IBM/DesignManagement/server/tomcat/work directory. I only see a catalina folder there.
If you reboot the server machine, clean up the diagram cache folder, how soon do you start getting out of handles problem? Do you just open diagrams in the web browser?

We have never been able to open a diagram using the web ui in this server. We are able to view the diagram using RSA eclipse client.

In dm.log we see that the SWT APIs are being invoked. If this is a Linux resource level issue then what would be your suggestion to resolve this? We checked the RDM Server diagnostics and the diagnostics are ok.

Just to confirm. You've installed the server, imported sample project via setup wizard. Now, went in to explorer to look at jke bankin model contents. Tried to open a diagram fo the first time and it crashed with out of handles error?!
Which brand of Linux are you running?

Yes you are right and we are running Red Hat Enterprise Linux Server release 5.8 (Tikanga).
