Subject [jira] [Commented] (SOLR-2233) DataImportHandler - JdbcDataSource is not thread safe
Date Tue, 31 May 2011 18:12:47 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13041724#comment-13041724

Frank Wesemann commented on SOLR-2233:
--------------------------------------

Fuad,
as the patch is not applyable for me ( too much noise about reformated lines etc.)
Do I see it right that you essentially replaced {{getConnection()}} with {{factory.call()}}
?

> Whenever Thread A spends more than 10 seconds on a Connection (by retrieving records
in a batch), Thread B will close connection.
> Related exceptions happen when we use "threads=" attribute for entity; usually exception
stack contains message "connection already closed"
> It shouldn't happen with some JNDI data source, where Connection.close() simply returns
Connection to a pool of available connections, but we might get different errors.
