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">

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.

Hi,

 

I have got a problem with the settings of log4net about multi access on a file.

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.
