Subject [jira] Commented: (JCR-2520) [JBoss] No ManagedConnections available / JCA max connection (session)
Date Thu, 25 Feb 2010 16:56:33 GMT

    [ https://issues.apache.org/jira/browse/JCR-2520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12838408#action_12838408

Cédric Chantepie commented on JCR-2520:
---------------------------------------

In fact limit can (must) be configured in *-ds.xml JBoss specific file. By default pool max
size is 20.

>             Project: Jackrabbit Content Repository
>          Issue Type: Bug
>          Components: jackrabbit-jca
>    Affects Versions: 2.0.0
>         Environment: JBoss 4.2.3.GA, PostgreSQL 8.x

> It seems that with Jackrabbit JCA 2.0.0 deployed on JBoss 4.2.3.GA, "only" 20 session
can be opened at the same time.
> When trying to open the 21th session, I get the following exception :

available within configured blocking timeout ( 30000 [ms] )

> I don't see this limit / max count in Jackrabbit JCA configuration. I've checked whether
it comes from underlying PersistenceManager.
> Persistence manager is postgresql bundle one from JNDI (with javax.naming.InitialContext
as driver).
> But JBoss JMX console displayed it still have available connection to used database whereas
Jackrabbit JCA keep throwing exception.
> Moreover I'm still able to use underlying datasource to get a JDBC connection and execute
a PreparedStatement ("SELECT * FROM default_bundle" as test).
> So as I think underlying datasource/persistence manager is ok, there may be a trouble
with Jackrabbit JCA.
