I used MySQL for my CDO repositories before. Everything worked well. However, I want to test Derby now. I changed my server code as follows:
EmbeddedDataSource dataSource = new EmbeddedDataSource();
dataSource.setDatabaseName(connectionData.getDbName());
dataSource.setCreateDatabase("create");
IStore store = CDODBUtil.createStore(
CDODBUtil.createHorizontalMappingStrategy(true),
new EmbeddedDerbyAdapter(),
DBUtil.createConnectionProvider(dataSource));
repository = CDOServerUtil.createRepository(
connectionData.getRepositoryName(), store,
new HashMap<String, String>());
CDOServerUtil.addRepository(IPluginContainer.INSTANCE, repository);
//...
When the repository is added, CDO/Net4j reports the following exception:
java.sql.SQLSyntaxErrorException: Table/View 'CDO_PROPERTIES' does not exist.
The DB has been created. When I check the DB, I cannot find any table inside. Did I miss something very important? As I said, using the MySQL Adapter the code above was sufficient and everything worked.
I use
CDO Model Repository SDK 4.2.0.v20130312-0827
Net4j DB Framework Derby Adapter 4.2.0.v20130116-0901 (however, the filename states org.eclipse.net4j.db.derby_4.1.0.v20130116-0901.jar)
I should also reference this topic, which reports the same problem. However, I cannot find a solution there (except using H2):

Thanks in advance!

I normally recommend to try out H2 instead because it's slimmer and much faster. And it's the DB we test each build with.

That all looks ok.

I suspect that something in your model is not supported by EmbeddedDerbyAdapter. Is there additional trace info in the
log? In standalone mode you can call this to enable logging and tracing:
// Enable logging and tracing
OMPlatform.INSTANCE.setDebugging(true);
OMPlatform.INSTANCE.addLogHandler(PrintLogHandler.CONSOLE);
OMPlatform.INSTANCE.addTraceHandler(PrintTraceHandler.CONSOLE);
Just this week I've finished a major rehaul of the Net4j DB framework and CDO's DBStore to make the schema handling more
stable and flexible:
[401763] Make CDO Server more robust against data dictionary changes
https://bugs.eclipse.org/bugs/show_bug.cgi?id=401763
You may want to try out the newest I-build to test it.

Okay, that's the newest I-build.

That's okay. The build qualifier is made of the timestamp of the latest modification in the plugin, i.e., it doesn't
change with each build unless there's actual change.

Yes, that sounds similar. But I need to see the exception that's traced in org.eclipse.net4j.spi.db.DBAdapter:
public boolean createTable(IDBTable table, Statement statement) throws DBException
{
boolean created = true;
try
{
doCreateTable(table, statement);
}
catch (SQLException ex)
{
created = false;
if (TRACER.isEnabled())
{
TRACER.trace("-- " + ex.getMessage()); //$NON-NLS-1$
}
}
validateTable(table, statement);
return created;
}
