Re: [Neo4j] Online Backup : wich package?
I progress slowly...but I have a new error.
Here is my code :
//create the graph
neo = new EmbeddedGraphDatabase(CONSTANTS.GRAPH_PATH);
graph = ObjectGraphFactory.instance().get(neo);
for (String datasource : new String[]{nioneodb, lucene}) {
neo.getConfig().getTxModule().getXaDataSourceManager()
.getXaDataSource( datasource ).keepLogicalLogs( true );
}
graph.close();
neo.shutdown();
/*
* here, I put my code to copy the content of the graph directory to
the backup directory
**/
//open again the graph
neo = new EmbeddedGraphDatabase(CONSTANTS.GRAPH_PATH);
graph = ObjectGraphFactory.instance().get(neo);
/**
* I create the backup graph
**/
EmbeddedGraphDatabase neo = GraphJo4neo.getGraphDatabaseService();
EmbeddedGraphDatabase backupGraphDb = new
EmbeddedGraphDatabase( CONSTANTS.GRAPH_BACKUP_PATH );
IndexService backupIndexService = new
LuceneIndexService( backupGraphDb );
Backup backup = new Neo4jBackup( neo, backupGraphDb,
new ArrayListString()
{
{
add( nioneodb );
add( lucene );
}
} );
try {
backup.enableFileLogger();
backup.setLogLevelDebug();
backup.doBackup(); // /!!\ : ERROR HERE
} catch (IOException e) {}
backupIndexService.shutdown();
backupGraphDb.shutdown();
But I obtain this error :
java.lang.RuntimeException: Missing log entry in backup source: [10]
in resource [nioneodb]. Can not perform backup.

The exception really says it all. You are trying to backup to a
target that
does not have the same origin as the source.
You need to create the target Neo4j store by either letting the
online-backup component create it, using the
Neo4jBackup(EmbeddedGraphDatabase, String, ...) constructors, or
manually
create a copy of the store on the file system level before you do the
initial copying.

Re: [Neo4j] Online Backup : wich package?
This error come from not configuring Neo4j to keep its logical logs.
The keepLogicalLogs( true ) parts need to be there for the part of the code
where you do the backups.

I committed a change that will let you decide which file the log is
written to. It's found here:
http://components.neo4j.org/neo4j-online-backup/apidocs/org/neo4j/onlinebackup/Backup.html#enableFileLogger%28java.lang.String%29
That is Backup.enableFileLogger(String filename)
If you use the snapshot version, it's there now. In the stable version
you can't do this.

Re: [Neo4j] Online Backup : wich package?
Hi Bat,
I've tried this with the combination of
* neo4j-kernel-1.0.jar (from neo4j-apoc-1.0)
* neo4j-online-backup-0.5.jar
That works fine.
Are you sure that you don't have incompatible versions on the class path as
well?
Try printing the classpath from your application and verify that you don't
have multiple versions of the same Neo4j library there:
System.out.println(System.getProperty(java.class.path));
Also, don't forget that you need to tell the data sources (nioneodb and
lucene) to keep their logical logs:
EmbeddedGraphDatabase neo = ...
for (String datasource : new String[]{nioneodb, lucene}) {
neo.getConfig().getTxModule().getXaDataSourceManager()
.getXaDataSource( datasource ).keepLogicalLogs( true );
}
Cheers,
Tobias

of code is correct :
//create the original graph
neo = new EmbeddedGraphDatabase(CONSTANTS.GRAPH_PATH);
graph = ObjectGraphFactory.instance().get(neo);
for (String datasource : new String[]{nioneodb, lucene}) {
neo.getConfig().getTxModule().getXaDataSourceManager()
.getXaDataSource( datasource ).keepLogicalLogs( true );
}
//create the backup graph
EmbeddedGraphDatabase neo = GraphJo4neo.getGraphDatabaseService();
EmbeddedGraphDatabase backupGraphDb = new
EmbeddedGraphDatabase( CONSTANTS.GRAPH_BACKUP_PATH );
IndexService backupIndexService = new
LuceneIndexService( backupGraphDb );
Backup backup = new Neo4jBackup( neo, backupGraphDb,
new ArrayListString()
{
{
add( nioneodb );
add( lucene );
}
} );
try {
backup.enableFileLogger();
backup.setLogLevelDebug();
backup.doBackup();
} catch (IOException e) {}
Basically, this part of code is right, isn'it?

Hi Bat,
I've tried this with the combination of
* neo4j-kernel-1.0.jar (from neo4j-apoc-1.0)
* neo4j-online-backup-0.5.jar
That works fine.
Are you sure that you don't have incompatible versions on the class
path as
well?
Try printing the classpath from your application and verify that you
don't
have multiple versions of the same Neo4j library there:
System.out.println(System.getProperty(java.class.path));
Also, don't forget that you need to tell the data sources (nioneodb
and
lucene) to keep their logical logs:
EmbeddedGraphDatabase neo = ...
for (String datasource : new String[]{nioneodb, lucene}) {
neo.getConfig().getTxModule().getXaDataSourceManager()
.getXaDataSource( datasource ).keepLogicalLogs( true );
}
Cheers,
Tobias

You could also use this code to print the classpath:
//Get the System Classloader
ClassLoader sysClassLoader = ClassLoader.getSystemClassLoader();
//Get the URLs
URL[] urls = ((URLClassLoader)sysClassLoader).getURLs();
*for*(*int *i=0; i urls.length; i++)

System.out.println(urls[i].getFile());

This might give a slightly more complete view of the paths from where
classes are loaded.

library directory, they might not appear in the java.class.path property)

Re: [Neo4j] Online Backup : wich package?
I fixed one problem. But I still have a problem.
My classes are starded from BlazeDS. It's a server-based Java remoting
installed on Glassfish. So, I can not see the packages of neo4j on the
classpath.
However, I use this packages :
lucene-core-2.9.1.jar
neo4j-remote-graphdb-0.5.jar
neo4j-commons-0.4.jar
neo4j-index-1.0-b1.jar

neo4j-shell-1.0-rc.jar
neo4j-apoc-examples-0.5.jar
neo4j-online-backup-0.5.jar
neo4j-remote-graphdb-0.5.jar

Re: [Neo4j] Online Backup : wich package?
The exception really says it all. You are trying to backup to a target that
does not have the same origin as the source.
You need to create the target Neo4j store by either letting the
online-backup component create it, using the
Neo4jBackup(EmbeddedGraphDatabase, String, ...) constructors, or manually
create a copy of the store on the file system level before you do the
initial copying.
Cheers,
Tobias

What version are you using of the neo4j kernel?
neo4j-kernel-1.0 should be used with neo4j-onlinebackup-0.5
