Hello Vikram,


I have enjoyed both of your articles. I am new to log4j and researching it for use across my company's applications.


We are running WebLogic clustered, so I am wondering what you mean when you say "I agree that log4j in a cluster is an issue"? What are the issues related to clustering??


Thanks,

    Hi Darryl,

    Log4J in a cluster is an issue if you are using FileAppender. The problem arises because of multiple process from multiple machines writing to the same file. Either you need to synchronize these processes by writing a buffer around the FileAppender or use some other appender like the SocketAppender or the JMSAppender.
