I want to start and configure a CDO server inside my application.
The cdo-config.xml I was using with the CDO server application looked
like this:

<?xml version="1.0" encoding="UTF-8"?>
<cdoServer>
<acceptor type="tcp" listenAddr="0.0.0.0" port="2036">
<!-- negotiator type="challenge" description="/temp/users.db"/ -->
</acceptor>
<repository name="repo1">
<property name="overrideUUID"
value="1ff5d226-b1f0-40fb-aba2-0c31b38c764f"/>
<property name="supportingAudits" value="false"/>
<property name="verifyingRevisions" value="false"/>
<property name="currentLRUCapacity" value="10000"/>
<property name="revisedLRUCapacity" value="100"/>

<store type="mem"/>
</repository>
</cdoServer>

Will the below code be equivalent to running the CDO server application
with the above config file?

IMEMStore store = MEMStoreUtil.createMEMStore();
Map<String, String> props = new HashMap<String, String>();
props.put(Props.SUPPORTING_AUDITS, "false");
props.put(Props.VERIFYING_REVISIONS, "false");
props.put(Props.CURRENT_LRU_CAPACITY, "10000");
props.put(Props.REVISED_LRU_CAPACITY, "100");
repository = CDOServerUtil.createRepository("repo1", store, props);
serverContainer = IPluginContainer.INSTANCE;
LifecycleUtil.activate(serverContainer);
CDOServerUtil.addRepository(serverContainer, repository);
acceptor = TCPUtil.getAcceptor(serverContainer, "0.0.0.0:2036");

( I did not include the 'overrideUUID'. Is it needed and if so why? )

I think it is good... in a OSGI context. If you are not... it will not
work.

You can find example here:
http://wiki.eclipse.org/User_Contributed_CDO_Documentation#S nippets

No it is not needed. If you do not provide one, a UUID will be generated
for you. (If I remember correctly)

In the future we are planning to remove it.

Hi,

I also am trying to start a server outside of eclipse and OSGI.

Well, thanks to your example, I was able to get an example that would run.
I'm using 3.5.M6, EMF 2.5.0, CDO/NET4J 2.0.0. This is my running server:
Now I need to figure out how to turn logging on so I can see what it's
doing...

Both the memstore and derby store work - I'm playing with getting
teneo/hibernate to work also.

public static void main(String[] args) throws InterruptedException,
IOException
{
// IMappingStrategy mappingStratgey =
CDODBUtil.createHorizontalMappingStrategy();
// IDBAdapter dbAdapter = new EmbeddedDerbyAdapter();
//
// EmbeddedDataSource dataSource = new EmbeddedDataSource();
// dataSource.setUser("sa");
// dataSource.setDatabaseName("/tmp/cdodb1");
// dataSource.setCreateDatabase("create");
//
// IDBConnectionProvider dbConnectionProvider =
DBUtil.createConnectionProvider(dataSource);
//
// IJDBCDelegateProvider delegateProvider = new
PreparedStatementJDBCDelegateProvider();
// IStore store = CDODBUtil.createStore(mappingStratgey, dbAdapter,
dbConnectionProvider, delegateProvider );

// IHibernateMappingProvider hibMappingProvider =
HibernateUtil.getInstance().createFileMappingProvider("model/ddd.xml ");
// IStore store2 = CDOHibernateUtil.createStore(hibMappingProvider);

IMEMStore store3 = MEMStoreUtil.createMEMStore();

Map<String,String> props = new HashMap<String,String>();
props.put(IRepository.Props.CURRENT_LRU_CAPACITY, "100000");

IRepository repository = CDOServerUtil.createRepository("repo1",
store3, props);

IManagedContainer container = ContainerUtil.createContainer();
Net4jUtil.prepareContainer(container);
TCPUtil.prepareContainer(container);
LifecycleUtil.activate(container);
CDOServerUtil.prepareContainer(container);
CDOServerUtil.addRepository(container, repository);

IAcceptor acceptor = TCPUtil.getAcceptor(container,
"0.0.0.0:2036");

System.out.println("Press any key to shut down (port:" +
acceptor.toString() + ")");

while (System.in.read() == -1)
{
Thread.sleep(200);
}
container.deactivate();
}

Hi Matthew,

I`m glad that you manage it!

For the logging you can look at the following:

The IPluginContainer is an IManagedContainer with the factories and
element processors populated from the extension registry. It should
automatically be activated, so no need to do it manually. Only if
running standalone, you need to prepare the container yourself and
activate it subsequently before filling it with elements.

It's not needed. As Simon said, it's generated at first startup of the
repository then. For test purposes it can be desirable to have a
predictable UUID,or you may want to have something shorter than a
regular UUID...
