Hi All,
We are implementing the tomcat load balancing for my application.
So, we need to share the same repository for all tomcats.
1) We have shared the repository folder for all tomcats (NSF mount)
2) added the cluster node in repository.xml
<Cluster id="node1">
<Journal class="org.apache.jackrabbit.core.journal.FileJournal">
<param name="revision" value="${rep.home}/revision.log" />
<param name="directory" value="${rep.home}/../shared" />
</Journal>
</Cluster>
3) added same repository.xml in all tomcats
4) First tomcat is started successfully
5) While starting the second tomcat, its throwing error.
Please advise.
Here is the error details:

the Repository element configures a repository instance; individual
workspaces of the repository are configured through separate configuration
files called workspace.xml which are located in a subfolder of the
workspaces root directory (see Workspaces element).
it consists of
- a FileSystem element (the virtual file system
used by the repository to persist global state such as
registered namespaces, custom node types, etc..
- a Security element that specifies the name of the app-entry
in the JAAS config and the access manager
- a Workspaces element that specifies the location of the
workspaces root directory, the name of the default workspace,
the maximum idle time before a workspace is automatically
shutdown (optional) and the workspace configuration root directory
within the virtual repository file system (optional)
- a Workspace element that is used as a workspace configuration
template; it is used to create the initial workspace if there's
no workspace yet and for creating additional workspaces through
the api
- a Versioning element that is used for configuring
versioning-related settings
- a SearchIndex element that is used for configuring Indexing-related
settings on the /jcr:system tree.

clustering node that synchronizes changes made in a cluster
