Cognos 10 Dev Edition on Amazon Web Services Problem

[tptolton]

I have been running Cognos 10 Dev Edition on Amazon Web Services.  The application installs and runs correctly on the instances I have created, and works just fine after the instance is rebooted.  I am able to connect to data sources and create reports without any issues. 

However, after I stop the instance (i.e. shut down) and then later restart it the application is no longer accessible until I once again reinstall everything from scratch.  When I attempt to access the Cognos Manager web site I am presented with a message that states "SDK-ERR-0088 The IBM Cognos BI Developer Edition service is currently unavailable."  This issue is not resolved by restarting the service.

The Cognos service successfully starts on bootup, and the cogserver.log file does not show any errors.  The only indication of an error comes when attempting to log into the dispatcher (http://cognos:9300/p2pd/servlet/dispatch).  The login screen here states "No valid license for IBM® Cognos® BI Developer Edition was detected."

I have tried both small and large 32 and 64 bit instances on Windows Server 2003 and 2008.  I am using EBS-backed instances.  The behavior is similar across all of them.

Any resolution ideas, or just thoughts on where to look would be greatly appreciated.

With luck, it's just the server name.  Don't let AWS change the server name on restart - before you install, go into windows -  Start, Programs,  EC2Config<something,something>

On the first panel, there is an option about rename server (first option) - uncheck it.

You may also want to rename to a friendly server name  prior to install.

If you're unlucky, the install is dependent on the server IP, which will always change on reboot (CX does that so never works after EBS restart)

Thanks for the note.  Prior to installing on my instances I did set the hostname to a friendly name, and set the EC2 config to persist my assigned name on restart.

The internal private IP address assigned to the instance changes on restart, so there is a chance that Cognos rejects the "license" when the IP address changes.  I have set a predictable public IP address (elastic IP) but I imagine that is transparent to the instance and only relates to routing from outside.  I also set up a loopback adapter on an instance to see if I could get Cognos to recognize that instead, to no avail.

Thank you for the help.  I'll keep looking a bit more for another solution.
