Subject [jira] [Commented] (LOG4J2-407) JDBCAppender cannot recover from loss of database connectivity
Date Wed, 13 Nov 2013 07:54:21 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13821043#comment-13821043

Dimitry Declercq commented on LOG4J2-407:

Any progress on this? I logged an issue yesterday concerning this (before I found this one)
I'm available to test any solution you have for this. We are also conducting some MySQL database
tests next week (failover, network failures, ...), if you can provide me with a patched version
we can check the behaviour of Log4J in these scenario's as well.

>                 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
> 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.
