RE: No appenders found
Do you have a
XmlConfigurator.Configure();
Or one of the other possibilities to configure log4net somewhere in your
code ?

However nothing gets written to event log, file or smtp. While debugging
there doesn't seem to be any appenders to the repository. So I'm presuming I
haven't set up my configuration properly. Unfortunately I can't see where
I'm going wrong - can you see where I'm going wrong?

RE: Experiencing locks while using AdoNetAppender
Ron and Michael thanks for your suggestions, It is indeed how SQLite works and the locking itself is not the problem. This is expected as multiple processes try to log at once. The ADODBAppender uses a internal buffer to store the logevents. The problem is that with default timeout for the DBCommand of 30 seconds (which is specified in the ADODBAppender) I experience out of memory exceptions as the internal buffers grow too fast while waiting for the timeout. A timeout of say 5s would be better for me. Or better make the timeout configurable through the config file of the ADODBAppender. What would be the best way to make the neccessary changes? Create my own version of the ADODBAppender?

From: Patrick Kalkman p...@hoogendoorn.nl To: log4net-user@logging.apache.org Sent: Tuesday, August 18, 2009 8:29:17 AM Subject: Experiencing locks while using AdoNetAppender Hi, I am using the AdoNetAppender for logging messages from multiple application. All the applications log into one sqllite database. Sometimes when a lot of information is logged I am experiencing exceptions like: log4net:ERROR [AdoNetAppender] Exception while writing to database System.Data.SQLite.SQLiteException: The database file is locked database is locked at System.Data.SQLite.SQLite3.Reset(SQLiteStatement stmt) at System.Data.SQLite.SQLite3.Step(SQLiteStatement stmt) at System.Data.SQLite.SQLiteCommand.ExecuteNonQuery() at System.Data.SQLite.SQLiteTransaction..ctor(SQLiteConnection connection, Boolean deferredLock) at System.Data.SQLite.SQLiteConnection.BeginTransaction(Boolean deferredLock) at System.Data.SQLite.SQLiteConnection.BeginDbTransaction(IsolationLevel isolationLevel) at System.Data.Common.DbConnection.System.Data.IDbConnection.BeginTransacti on() at log4net.Appender.AdoNetAppender.SendBuffer(LoggingEvent[] events) The default CommandTimeout in the AdoNetAppender on the IDbCommand is 30 seconds, but I would like to influence this timeout in the log4net configuration (file) so that I can influence the timeout on the logging if the database is locked for a longer portion of time. Reducing the timeout may lead to events getting lost, but I prefer that to our application hanging for the full CommandTimeout waiting for the database to become unlocked. Is it possible to configure the timeout using configuration? or would it be better to choose for a solution like deriving from the AdoNetAppender and add the functionality?

RE: No appenders found
Thanks Ross, that's it logging now.
Unfortunately it's only using the appenders as specified in the root element,
even though I'm trying to access it by MyLogger name. So I presume MyLogger
isn't registered with the default repository? Should I therefore create a new
repository with MyLogger name in order to use that Logger?
Also is there some documentation that shows all the configuration elements? I
looked at the SDK but I couldn't find it.
Thanks again for all your help.

Sidharth

Sidharth,
I think it depends on the log4net section handler you're using. That overload
of configure has specifies that the configuration must use the
Log4NetConfigurationSectionHandler. See:
http://logging.apache.org/log4net/release/sdk/log4net.Config.XmlConfigurator.Configure_overload_2.html
for more information.
Alternatively, you could try the following in your code:
log4net.Config.XmlConfigurator.Configure(new
FileInfo(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile));

Hi Wolfgang,
Thanks for your quick response.
I've added this to the code now:
if (!_defaultLog.Logger.Repository.Configured)
{
log4net.Config.XmlConfigurator.Configure(_defaultLog.Logger.Repository);
}
But the repository is still appearing as unconfigured and still no appenders.
I've even tried doing a default XmlConfigurator.Configure(); before GetLogger()
call. Is that the right way of calling the Configure() method?
