Nick Williams resolved LOG4J2-407. ---------------------------------- Resolution: Fixed Fix Version/s: 2.0-rc1 Fixed with r1565858 and r1565878. The database appenders now connect to the database (i.e., borrow from the connection pool) and begin a transaction on every flush or every non-buffered {{writeInternal}}, then commit and disconnect (i.e., return to pool) at the end of the flush or non-buffered {{writeInternal}}. Note also that the {{<DriverManager...>}} connection source plugin is no longer available. It was removed because it was unsafe and didn't support connection pooling. Please use the {{<DataSource...>}} or {{<ConnectionFactory...>}} connection source plugins, instead. > JDBCAppender cannot recover from loss of database connectivity > -------------------------------------------------------------- > > Key: LOG4J2-407 > URL: https://issues.apache.org/jira/browse/LOG4J2-407 > Project: Log4j 2 > Issue Type: Bug > Components: Appenders > Affects Versions: 2.0-beta9 > Reporter: Michael Kloster > Assignee: Nick Williams > Fix For: 2.0-rc1 > > > The JDBCAppender holds a single database connection for all its logging. If > that database connection is closed, it does not attempt to make a new > connection. > Many connection pools automatically close connections after a certain amount > of inactivity. (This can be worked around by properly configuring a pool). > Database connectivity issues are also common enough that a long running > application may experience temporary network issues. When the network comes > back online, the logging will not resume. > I've been meaning to submit a patch for this, but I haven't gotten to it. > Since I saw that you are looking to come out of beta soon, I thought I would > log this issue in case someone else has time to write the patch before I get > to it. -- This message was sent by Atlassian JIRA (v6.1.5#6160) --------------------------------------------------------------------- To unsubscribe, e-mail: log4j-dev-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-dev-h...@logging.apache.org
