I don't quite understand what you're looking for. If you'd like to delete a
node with all its relationships you can do 'rmnode -f node-id' or 'rmnode
-f' so that the current node is used.
Are you looking for a way to just delete all relationships from a node, but
not the node itself or a way to

To make things work correctly, one important change to core is needed: The
When running the mvn install, both tests are ran after another.
Since I didn't use mvn (xD) I ran the tests manually one by one, but what
you say makes sense, it's likely the tests fail when ran one after the
other, I'll see what happens with an @Suite
since there are only 2 junit tests, with

I am looking for ways to delete all connected nodes that can be reached
thought any or sepcific relationships, i.e., deleting all
nodes/relationships other than the reference node (node 0). A smilar
capability in RDBMS is called cascade delete through foreign keys from the
parent table.

Does one need to specify the following list of node_keys_indexable
relationship_keys_indexable in neo4j.property to enable auto indexing for
those node/relationship properties? Also, will they work if those properties
were created prior to adding the list in neo4j.property file?
I use the download option on Github expand the zip in a directory and run mvn
install in that directory without any problems.

looking at this you should be able to provide your own Configurator

Thanks Niels, I just tried what you said, with maven 3.0.3 it seemed to do

from my experience this kind of behaviour would happen mostly due to using
some static fields which are expected to be in initialized state for each

Ok, up until now I've had almost no idea what is happening, what those tests
are doing and stuff, so I was blindly trying to fix things, it sort of
worked until now; looks like I have to begin to understand what is going on;
so I will delve deeper into this and understand what is going on exactly
looks like before delving too deep, I found that attempting to deleting the

that method is deferring the shutdown to another thread and thus is
non-blocking (due to my timing of

So far I've found that, bdb environment(and relevant databases) is(are) only
closed when index.delete() is called
and that can only be called when the current transaction is finished (else
it will complain that some bdb databases are not opened on txn commit)
Applying all
found out that I don't need to call index.delete() all the time, instead
BerkeleyDbDataSource.close() aka XaDataSource.close() should do what
index.delete() does, namely closing all databases (related to this
datasource) and their bdb environment; so I do just that.
Therefore I answer some parts
The problem is indeed related to not properly closing the bdb database, and
that is triggers another problem. In BerkeleyDbCommand data is being stored
into the transaction log and been read from the transaction log later on.
Something goes wrong making the indexName being retrieved from the

a need to add xaContainer.close(); to

Now there's a messages.log still open, working on that xD

I did a quick check of what you said
org.neo4j.index.bdbje.BerkeleyDbCommand.writeToFile(LogBuffer)
char[] indexName = indexId.indexName.toCharArray();
buffer.putInt( indexName.length );
buffer.put( indexName );
I'm probably missing something but on my side it looks like it writes length

Could you check if the neo4j kernel jar file maven adds to class path is
correct and complete. You can find it in your user directory in the .m2
