Logging from multiple apps/processes to a single l

Question

Our app servers (weblogic) all use log4j to log to the same file on a network share. On top of this we have all web apps in a managed server logging errors to a common error.log. I can't imagine this is a good idea but wanted to hear from some pros. I know that each web app has its own classloader, so any thread synchronization only occurs within the app. So what happens when multiple processes start converging on a single log file? Can we expect interspersed log statements? Performance problems? What about multiple web apps logging to a common log file? The environment is Solaris.

Answer 1

We have a requirement where we need to produce a single file from all the managed server running the same application . we developed a java logging server which opens ups a port and listen for log event. we used the log4j socket appender to write log event to the same port and created a single file.
