Re: [Neo4j] neo4j REST server standalone
I downloaded the July 10th build of the REST standalone server and created a neo4j.properties file with enable_remote_shell set to true. However, when I try to connect it, I still get the locked store message and it prompts me to open as readonly. Do I also need something in the wrapper.conf file? Also, used JConsole to see the configuration attributes which show up as unavailable. I think the problem is that you supply a -path at the shell client command line, am I right? Because when supplying a -path option it will try to open that graph database in the shell client JVM. If you skip that -path option it will try to connect via RMI to a remotely enabled shell server instead and you'll get a remote client with read/write capabilities.

Are you planning to do online backup to another running database or to another disk? I plan to backup to another drive on the same disk. The shell is now also startable via a configuration parameter, so if you supply a enable_remote_shell=true parameter in that neo4j.properties file it will be started.

Re: [Neo4j] neo4j REST server standalone
Hi Mohit, the admin system is meant to eventually be able to provide support for live backups, although there is quite a bit of work left on other components first. The admin interface currently depends on the REST package which, afaik, does not turn on the command-line shell by default. There will be an integrated gremlin web console though. It would probably not be that difficult to add a setting for enabling/disabling command-line shell access though. I added this as a ticket to the github project - http://github.com/neo4j/webadmin/issues/issue/8. /Jacob On Thu, Jul 1, 2010 at 11:34 PM, Mohit Vazirani mohi...@yahoo.com wrote: - Original Message From: Mattias Persson matt...@neotechnology.com To: Neo4j user discussions user@lists.neo4j.org Sent: Thu, July 1, 2010 6:53:48 AM Subject: Re: [Neo4j] neo4j REST server standalone Hi, I'm guessing you would like to specify a configuration file for the database, right?

Recently set up the standalone rest server in linux (started using neo4j-rest start). I was reviewing http://wiki.neo4j.org/content/Configuration_Settings and was wondering how to specify memory-mapped I/O settings other backup-related settings to the REST server. I couldn't find any section in wrapper.conf that allowed me to do this.
