Hi,
I am implemented transaction handling based on Jena TDB 2.11 on Tomcat.
But when initializing the model accordingly:
if( file.exists() ) {
dataset = TDBFactory.createDataset(tdbDirectory)
dataset.begin(ReadWrite.WRITE);
mRootModel = dataset.getDefaultModel();
try {
dataset.commit();
} catch (Exception ex) {
System.out.println("*** error initilizing dataset: " + ex + "
[DataManager/Initialize] ");
} finally {
dataset.end();
}
} else {
file.mkdir();
}
if( mRootModel == null || mRootModel.isEmpty() ) {
dataset.begin(ReadWrite.WRITE);
loadOntology();
try {
dataset.commit();
} catch (Exception ex) {
System.out.println("*** error loading model: " + ex + "
[DataManager/Initialize]");
} finally {
dataset.end();
}
}
I get the following errors:
Updated default model. Size: 0 [DataManager/Initialize]

-------------------------
Does it mean the transaction is not active?
and when committing the model it generates the error:
Inconsistency: base.allocOffset() = 55554 : allocOffset = 53904
I have trouble understand what happens. What does the '1' mean in "Not
active 1"?
and does " Inconsistency: base.allocOffset() = 55554 : allocOffset = 53904"
indicate that TDB did not persist? And What us Block 24576?
