Hi,
I'm trying to use MongoDB store with CDO 4.1 model repository.
When I start the CDO repository with the following configuration for the first time:
<?xml version="1.0" encoding="UTF-8"?>
<cdoServer>
<acceptor type="tcp" listenerAddr="0.0.0.0" port="2036">
<!-- <negotiator type="challenge" description="/temp/users.db"/> -->
</acceptor>
<repository name="myrepo">
<property name="overrideUUID" value="" />
<property name="supportingAudits" value="false" />
<property name="supportingBranches" value="false" />
<property name="supportingEcore" value="false" />
<property name="ensureReferentialIntegrity" value="false" />
<property name="allowInterruptRunningQueries" value="true" />
<property name="idGenerationLocation" value="STORE" /> <!-- Possible values: STORE | CLIENT -->
<!-- ONLY THE FIRST CONFIGURED STORE IS USED FOR THE REPOSITORY!!! -->
<store type="mongodb">
<property name="uri" value="mongodb://localhost"/>
<property name="db" value="mydb"/>
<property name="drop" value="false"/>
</store>
</repository>
</cdoServer>
everything works fine.
After my application writes some data into the repository and I properly restart it by performing:
...
osgi>cdo stop myrepo
...
On the next start up the CDO repository application fails to start by throwing the following exception:
Caused by: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://www.eclipse.org/emf/2002/Ecore' not found. (http://www.eclipse.org/mymodel/1.0, 3, 135)

The crash detection works as follows:
protected void reStart()
{
Set<String> names = new HashSet<String>();
names.add(Props.GRACEFULLY_SHUT_DOWN);
Map<String, String> map = getPersistentProperties(names);
if (map.containsKey(Props.GRACEFULLY_SHUT_DOWN))
{
...
}
else
{
repairAfterCrash();
}
removePersistentProperties(Collections.singleton(Props.GRACEFULLY_SHUT_DOWN));
}
So it seems that the GRACEFULLY_SHUT_DOWN property doesn't get set in doDeactivate():
protected void doDeactivate() throws Exception
{
Map<String, String> map = new HashMap<String, String>();
map.put(Props.GRACEFULLY_SHUT_DOWN, Boolean.TRUE.toString());
setPersistentProperties(map);
}
Maybe with the debugger you can find out why?
Cheers
