Subject [jira] Created: (JCR-1060) New workspaces created in 1 cluster node are not automatically available in other cluster nodes
Date Wed, 15 Aug 2007 07:47:30 GMT
New workspaces created in 1 cluster node are not automatically available in other cluster nodes
-----------------------------------------------------------------------------------------------

                 Key: JCR-1060
                 URL: https://issues.apache.org/jira/browse/JCR-1060
             Project: Jackrabbit
          Issue Type: Bug
          Components: clustering
    Affects Versions: 1.3.1
         Environment: Affects all environments. We're testing with Fedora Core 4, Mysql, Tomcat
5.0.30 and JDK 1.5.0_11
            Reporter: Shaun Barriball


New workspaces are not clustered. 
Creating a new workspace (Workspace2) on node A does not result in a new workspace being created
on node B e.g.

Node A file system:
	Repository
	Version
	Workspaces
		Workspace1
		Workspace2

 

Node B file system:
	Repository
	Version
	Workspaces
		Workspace1

This is problem for us as new workspaces are being created all the time, hence they must be
automatically clustered. 

I'm guessing this problem occurs as the "create workspace" mechanism is JackRabbit specific
and is outside of the JCR spec and event model?

 

Potential solutions:

.        Move to a DatabaseFileSystem - there are a couple of disadvantages
to this for us. We like to be able to view and amend the files and in particular we regularly
updated the custom_nodetypes.xml with new types as part of an upgrade process. Presumably
the nodes types would be less accessible within the database.

.        Use a Network File Share for local files - we're trying to achieve
the simplest solution for fault tolerance therefore we'd rather avoid the complication of
filesystem replication schemes (Linux DRBD etc) or the expense of SAN solutions.

.        Manually create copy new workspaces - also not really an option as
new workspaces are created all the time
