This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Our J2EE application is highly scalable and 24*7 availability. It's clustered(Web Server, App Server, DB). Can you suggest some tools to monitor the production application issues from client, business tier, persistence tier, integration tier and DB tier ?
