Re: [Neo] Looking at DB contents
I don't follow entirely... you mean that the shell held locks on nodes which made another traverser (executed via script or something) wait? At the moment every command in the shell is wrapped in its own transaction. 2009/9/7 Todd Stavish toddstav...@gmail.com: Hi Martin, Anders, The standalone version of neoclipse works like a charm, thanks. I was surprised that the shell locked out a non-updating traverse application that I wrote. Where do I explicitly declare locking? My natural assumption was in beginTx( kindOfLock ).

Re: [Neo] Looking at DB contents
Hi Mattias, Yes, that is correct. I think fundamentally I do not understand how your locking works. I assumed that both the shell and traverser would have read only locks. However, I left the shell open and the traverser was blocked. I did not do anything in the shell other than read-only commands. -Todd On Wed, Sep 9, 2009 at 5:47 AM, Mattias Persson matt...@neotechnology.comwrote: I don't follow entirely... you mean that the shell held locks on nodes which made another traverser (executed via script or something) wait?

Re: [Neo] Looking at DB contents
That's strange since the shell only wraps commands in transactions. This means that leaving the shell open, just standing on a node doesn't create/hold a lock or transaction whatsoever. You could debug this kind of problem (when it appears) by making a complete thread dump and you'll see which threads are holding neo4j locks, to see if it's really the shell which has locks or not. 2009/9/9 Todd Stavish toddstav...@gmail.com: Hi Mattias, Yes, that is correct.

Re: [Neo] Looking at DB contents
Btw. are you using the shell to connect remotely to a running NeoService or or you using it to start a local one? If you're starting a local (inside the shell JVM) you might have the problem that the neo4j files are locked so that you cannot start up your traverser application... is that the case? 2009/9/9 Mattias Persson matt...@neotechnology.com: That's strange since the shell only wraps commands in transactions.

Hi Todd! Are there command line tools that can output the database \ nodes to text? Or any quick way to inspect the contents of Neo? There's the Shell tool: http://wiki.neo4j.org/content/Shell I didn't have luck getting Neoclipse to work.
