Subject [jira] [Commented] (LOG4J2-407) JDBCAppender cannot recover from loss of database connectivity
Date Mon, 03 Feb 2014 04:44:10 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13889216#comment-13889216

Matt Sicker commented on LOG4J2-407:

One possibility would be to use Commons Pool for pooling Connection objects. It's no good
to keep closing connection objects from what I recall.

>             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.
