Deploying to multiple servers


  • Subject: Deploying to multiple servers

I'm trying set up an app to run on multiple servers and I'm having some problems.  I got it working in my dev environment, but production is not working.

The setup is like this:
1) Server1 is the primary entrypoint (or proxy) - it does Apache and JavaMonitor and 1/2 of the app instances
2) Server2 is the secondary server - it does the other 1/2 of the app instances
 
To debug it I have an app configured with just 1 instance running on the Server2, so in this case Server1 just acts as a proxy since there is no balancing to do.  
- Everything looks fine in JavaMonitor.  
- Requests made directly to Server2 work fine
- Requests made through Server1 hang for a long time and then say "No instance available".

Does anyone have suggestions for how to going about debugging this?

Thanks,
John
