Subject AW: Async appender and database logging
Date Wed, 20 Feb 2008 16:42:02 GMT
Hi Mailinglist,

here my DBAppender and AsyncAppender configuration:
<appender name="DB" class="org.apache.log4j.db.DBAppender">
       <connectionSource class="org.apache.log4j.db.DriverManagerConnectionSource">
         <param name="driverClass" value="oracle.jdbc.driver.OracleDriver"/>
         <param name="url" value="URL.to.database"/>
         <param name="user" value="xxx"/>
         <param name="password" value="xxx"/>
       </connectionSource>
  </appender>
  
  <appender name="ASYNC" class="org.apache.log4j.AsyncAppender">
  	<param name="locationInfo" value="true"/>
  	<appender-ref ref="DB" />
  	<appender-ref ref="FILE" />
  </appender>

The testing without the async logger shows to me, that the databse settings are correct.

Greetings,
Andreas

I don't know if the AyscAppender has been fixed in that version.
Can you show how you are configuring the AyscAppender and DBAppender?
