Subject [jira] Resolved: (JCR-1940) Exception when concurrently adding documents to Jack rabbit repository with clustering enabled
Date Mon, 16 Feb 2009 17:58:02 GMT

     [ https://issues.apache.org/jira/browse/JCR-1940?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jukka Zitting resolved JCR-1940.
--------------------------------

    Resolution: Invalid

Re-resolving as Invalid.

Alexander's concern about a potential clustering issue would only have been valid if your
non-clustered configuration would have been correct. As it stands, you're seeing normal Jackrabbit
behaviour described by Alexander.

Please contact the users@jackrabbit.apache.org list for more background on why Jackrabbit
does this, and for ways to avoid such issues. The issue tracker is only for cases where changes
to Jackrabbit behaviour is needed.

> We have a enabled jackrabbit clustering. In this mode following exception occurs when
2 users simultaneouly add documents to Jack rabbit repository registered with node id 1 and
2 respectively-
> 14:59:55,312 ERROR [DocumentHelper] Exception occurred while adding a manually uploaded
document to the jackrabbit:
> javax.jcr.InvalidItemStateException: cafebabe-cafe-babe-cafe-babecafebabe has been modified
externally
>         at org.apache.jackrabbit.core.ItemImpl.save(ItemImpl.java:1109)
>         at org.apache.jackrabbit.core.SessionImpl.save(SessionImpl.java:846)
> Another observation is that when we disable clustering and both users have same node
id in cluster configuration in repository.xml, the error doesnt appear.
