[Log4cplus-devel] RollingFileAppender in Multi threading based application

[qwerty m. <qwe...@gm...>]

Team,

I am new to this mailing list. I don't have any prior knowledge on log4j as
well. I want to use this log4cplus in our multi threading based larger
application.

I have some questions for implementing RollingFileAppender in multi
threading application.

Ours is a small backup application written in C++ having both client and
server side components. Multiple clients can connect to the server
simultaneously and send their backup data. I want to add logs for debugging
in server side.

This is my idea. I will have separate log file for each backup processing
in the server side assuming backup name is unique here. Three threads will
be involved in the server side for processing every backup received from
the client side.

Can I share the Logger object between the threads processing single backup
in the server side ?. I had planned to achieve this by using a static map
having backup name as key and Logger object as value here. And then from
each thread, I will get this logger object from the map and then call the
logging macros as below,

LOG4CPLUS_XX(LoggerObj, LogMessage); # This happens with the same logger
object from multiple threads.

Do I have to use any mutex if I share the same logger object between
different threads processing same backup ?.

I have read from some forums that RollingFileAppender does synchronous
write operations. Please confirm the same.

If you could also point me some examples for my case, it will be very
helpful.

Thanks in advance,
Prabu
