Hi,
I'm facing the exception that I include below. I guess this is because I'm not
properly opening a transaction or so.
Yes - and also not using the datasets MRSW lock (multiple reader /
single writer).
Concurrent access must be controlled by a transaction or the datasets
lock. Ideally, transactions.
Let's try to explain a bit to guess if this is the problem:
- I have multiple graphs which I merge using MultiUnion
- I generate the MultiUnion in one transaction, but the use of the joined graph
is done in another transaction.
Is the MultiUnion over graphs in the same dataset?
- I use a single static final Dataset from
TDBFactory.createDataset(TRIPLE_STORE_PATH);
- Read and write operations are done in different threads, so maybe we have
started a join for read and in parallel we are writing on one of the graphs
included in the union.
Any hint is welcome.
Regards,
Jorge
