[Neo4j] Log message for unmanaged extension
Hi, I tried to debug my unmanaged extension with private static final Logger log = Logger.getLogger(Register.class); and generate a message like: log.warn(passed check point 1); But I couldn't find any these messages from any log files, neo4j.0.0.log, console.log, message.log...etc How should I setup the log message?

[Neo4j] Server log file for HA
Hi, I could not find any log message for unmanaged extension when a 500 error respond generated in HA configuration.Does neo4j rest server generate any message for unmanaged extension?

Re: [Neo4j] Iterable handling in unmanaged server extension
Hi, is the Neo4j specific annotations for managed server plugin still available for unmanaged extension?Or do I have to use all Jersey annotations instead? Regards, Brendan From: peter.neuba...@neotechnology.com Date: Sun, 23 Oct 2011 04:46:02 + To: user@lists.neo4j.org Subject: Re: [Neo4j] Iterable handling in unmanaged server extension Brendan, the docs for the API are at http://docs.neo4j.org/chunked/snapshot/rest-api.html, let us know if this is good info for you. Regarding the filtering, Jim, do you have any thoughts on this? It seems that this looks a lot like the security rules that are in the server, see http://docs.neo4j.org/chunked/snapshot/security-server.html#_server_authorization_rules . In there, you can intercept access to the REST API faine-grained. If you got access to the database instance, you could even look up nodes and act according to the content, as you mentioned. Would having access to a database instance from within a security rule be a solution to your usecase? Otherwise, yes, writing your own REST API is of course possible with the unmanaged extensions. Let me know if I can help you with that.

}
--- if (!rel.hasProperty(UPDATED_DATE)
---|| ((Long)
rel.getProperty(UPDATED_DATE) = timestamp)) {
---return Evaluation.EXCLUDE_AND_CONTINUE;
--- }
//checking the stopping class type
Class C;
try {
C =
Class.forName(node.getProperty(NodeImpl.CLASS).toString());
if (C == PersonImpl.class || C ==

} catch (ClassNotFoundException ex) {

}
}
if (path.length() 0

int counter = 0;

any idea?
Hmm, not really... I just downloaded 1.3.M02 package, edited
conf/neo4j.properties file and added:
enable_online_backup = true
Then called:
./bin/neo4j start
I then wrote a class using the classpath from the unpacked 1.3.M02 package
containing:
public class Backup
{
public static void main( String[] args )
{
OnlineBackup.from( localhost ).full( myBackup ).close();
}
}
And it worked. Have you done exactly like me?
Best,
Mattias

The Neo4j server is registered at port 7474, but the backup server isn't...
you usually don't need to specify port so that the default can be used.
What
you'll have to do is:
* Add enable_online_backup = true to your neo4j configuration file and
restart the server (if that wasn't the case).
* Use OnlineBackup.from( localhost );
and it should work (just tried it).

Hi,
I was trying to test the online backup process. I received a
ComException saying Channel has been closed.
Here is my code which is copied from your Testbackup with a small
modification:
private String serverPath = localhost;
private String backupPath = target/var/backuedup-serverdb;
public void fullThenIncremental() throws Exception
{
ServerInterface server = startServer();
OnlineBackup backup = OnlineBackup.from( localhost,7474 );
backup.full( backupPath );
shutdownServer( server );
DbRepresentation furtherRepresentation = addMoreData();
server = startServer();
backup.incremental( backupPath );
assertEquals( furtherRepresentation, DbRepresentation.of(
backupPath ) );
shutdownServer( server );
}

The Neo4j server is registered at port 7474, but the backup server isn't...
you usually don't need to specify port so that the default can be used. What
you'll have to do is:
* Add enable_online_backup = true to your neo4j configuration file and
restart the server (if that wasn't the case).
* Use OnlineBackup.from( localhost );
and it should work (just tried it).

Hi,
I was trying to test the online backup process. I received a
ComException saying Channel has been closed.
Here is my code which is copied from your Testbackup with a small
modification:
private String serverPath = localhost;
private String backupPath = target/var/backuedup-serverdb;
public void fullThenIncremental() throws Exception
{
ServerInterface server = startServer();
OnlineBackup backup = OnlineBackup.from( localhost,7474 );
backup.full( backupPath );
shutdownServer( server );
DbRepresentation furtherRepresentation = addMoreData();
server = startServer();
backup.incremental( backupPath );
assertEquals( furtherRepresentation, DbRepresentation.of(
backupPath ) );
shutdownServer( server );
}
and the error message is:
run:
Mon Feb 14 13:37:54 CST 2011: Client connected to localhost:7474

I have my db server started as window service.
Also, I want to know if we need the process startServer() if the db
server has been started.

[Neo4j] Synchronisation between server and clients in Neo4j
Hi, I'm thinking of setting a system where each client store part of the server data for offline assess or reducing the workload of server. I'm not sure if there is a recommended way pf doing it. How should I do the synchronization for only part of data in most efficient way? Should I using the database log files to syn?
