Accessing files across clusters

I wasn't sure if this would go here or in the Off-Topic, so I flipped a coin.

Background: My workplace has an EVAL environment and a PROD environment which are basically off-limits to developers. These are unix boxes which have weblogic servers in a cluster. Logical or Physical, I am not sure. We developers of applications don't even have access to the logs etc. This is a major pain in the ass since the snotty-assed unix admins require a "upper level clearance" before they can hand us log files. Jeez !

Possible Solution: An idea that me and a fellow developer has suggested to our bosses, is to have a link in all of our apps called "View Logs" which will be accessible only to developers of the said app. Our bosses have told us that if we can do something like this, they would push the required buttons to get us access to the log files of individual apps so that we can display it in the app itself or allow them to download it.

The solution seems easy enough to implement on a single instance of a server. You get access to the logs and just display the last 200 odd lines on a html page or give them the option of downloading the entire file. However, because our servers are in a cluster, if any error has occurred on server2, and if the developer logs on server1, he will never be able to see the same log file. And because of sticky sessions, refresh of the page is not going to connect him to the other server either.

So I wanted to ask if anyone had any experience with something like this. How can one access files across a different server on the same cluster? I will have to check any solutions that you guys provide, to make sure if it passes company security policies etc.etc. So any other solutions (totally unrelated to the above) are welcome too.

Thanks

Re: Accessing files across clusters

Wow,  cool. There is no knowledge about cluster on my side. However, speaking of several hosts connected in one network, yes.

AFAIK, several nodes in the cluster would be accessible via a unique NIC and thus IP. Maybe you can  setup the solution you mentioned on every node / virtual node? You can probably have a script solution to pull from every node and grep for the interessting lines.
