Yep, i did it, it works, but now i'v got an other problem, i can't use an appendFile with the rolling on size or by date.
Here is what I've done : <appender name="FileAppender" type="log4net.Appender.FileAppender"> <file value="E:\\Log\\ArlSQL_Log\\ArlSql.log" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <layout type="log4net.Layout.PatternLayout" value="%d [%t] %-5p %c - %m%n" /> </appender> But for example, <maximumFileSize value="1MB" /> isn't usable with a type="log4net.Appender.FileAppender"> L De : Florin Daneliuc [mailto:florin.danel...@iquestint.com] Envoyé : vendredi 23 octobre 2009 15:26 À : Log4NET User Objet : RE: multi process settings I think you can also instruct the logger to try to acquire the lock of the file and release it as soon as possible. Anyway, for multiple process logging, a file is not the best way. Maiby an event log (windows) or syslog (nix) or a network sink might work better. florin ________________________________ From: Jordan JBO.

My context : I'v got a dll wich log into a trace.log. That dll is used by 2 different programs. When the first create the instance of log4net, the 2nd one can't write into the trace.log. I can't find the right settings to do that. The best behavior would be to create a new file with YYYYMMdd-HH_mm_ss when the instance can't write into the file. For now, I did, following the config-exemple from the apache site : <log4net> <root> <level value="ALL" /> <appender-ref ref="FileAppender" /> </root> <appender name="FileAppender" type="log4net.Appender.RollingFileAppender"> <file value="E:\\Log\\Trace.log" /> <appendToFile value="True" /> <rollingStyle value="Date" /> <staticLogFileName value="false" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock " /> <datePattern value="yyyyMMdd-HHmm" /> <maxSizeRollBackups value="-1" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%-5level] : %message%newline" /> </layout> </appender> </log4net> But I'm having an error with the 2nd instance wich is : System.TypeLoadException: Could not load type [log4net.Appender.FileAppender+MinimalLock ]. Tried assembly [log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821] and all loaded assemblies. Is there a solution to that ? Thanks.
