Subject [jira] Commented: (JCR-1975) Connection timed out IO Exceptions
Date Wed, 11 Feb 2009 16:34:59 GMT

    [ https://issues.apache.org/jira/browse/JCR-1975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12672671#action_12672671

Edgar Vonk commented on JCR-1975:

PS: the Jackrabbit config I posted is not up-to-date anymore because we have switched to 'externalBLOBs
= true" a while ago. Apart from this the set-up is still the same.

>                 URL: https://issues.apache.org/jira/browse/JCR-1975
>             Project: Jackrabbit Content Repository
>          Issue Type: Bug
>          Components: jackrabbit-api, jackrabbit-core, jackrabbit-jcr-commons, jackrabbit-spi,
jackrabbit-spi-commons, jackrabbit-text-extractors
>    Affects Versions: core 1.4.5
>         Environment: Linux (CentOs), Oracle XE 10g, Tomcat 6, JDK 1.6, Magnolia Enterprise
3.6.3, JNDI
>            Reporter: Edgar Vonk

> We are running Jackrabbit 1.4.5 as part of the Magnolia Enterprise CMS. We are running
into Jackrabbit - database connection problems on some occasions. We do not understand why
and when these happen. When they do all we can do is restart Tomcat (with Magnolia) and then
everything seems to run fine again until the next time this happens.
> We have looked into this issue together with Magnolia but have so far failed to come
up with a solution. We have not even been able to reproduce the issue. It only happens on
our production environment (where we have the database server on a separate machine from our
two app servers).
> I have also reported this issue on the Magnolia form: http://www.nabble.com/Using-Oracle-with-a-JNDI-datasource-in-Tomcat-td21114284.html
> We are using a JNDI persistence manager set-up. Our Jackrabbit persistence manager configuration
looks as follows:
> {code}
> <PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.OraclePersistenceManager">
>   <param name="driver" value="javax.naming.InitialContext" />
>   <param name="url" value="java:comp/env/jdbc/magnolia" />
>   <param name="schemaObjectPrefix" value="${wsp.name}_" />
>   <param name="externalBLOBs" value="false" />
> </PersistenceManager>
> {code}
> Our datasource in Tomcat:
> {code}
> 	<Resource 
> 		name="jdbc/magnolia" 
> 		auth="Container" 
> 		type="javax.sql.DataSource"
> 		driverClassName="oracle.jdbc.OracleDriver" 
> 		url="jdbc:oracle:thin:@//CHANGEME:1521/XEXDB"
> 		username="CHANGEME" 
> 		password="CHANGEME" 
> 		maxActive="20" 
> 		maxIdle="10" 
> 		maxWait="-1" />
> {code}
> In the log files we see:
> java.sql.SQLRecoverableException: Io exception: Connection timed out
> I will upload the full log file excerpt.
