RE: multi process settings

[Florin Daneliuc]

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.

Subject: RE: multi process settings

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.
