Subject [jira] [Commented] (LOG4J2-407) JDBCAppender cannot recover from loss of database connectivity
Date Thu, 09 Jan 2014 15:58:54 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13866734#comment-13866734

Matt Sicker commented on LOG4J2-407:
------------------------------------

The problem with that is there's a contract on the AbstractDatabaseAppender that writeInternal()
won't call connect() more than once. Then again, this isn't using the super.connect() method,
so that might be a better idea.

> 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.
