Basic question on transactions

Hi list,A have a few very basic question regarding transactions in Alfresco:1. Looking at the NodeService Java API, no routine seems to take a transaction as a parameter.

1. Looking at the NodeService Java API, no routine seems to take a transaction as a parameter. This is because every call to the API will run in its own transaction, as documented here. However, if you begin a transaction obtained via getUserTransaction() then the API is using this as the "global transaction". Is this correct so far?

2. Is this global transaction per Java thread?

It's a transaction per thread.

3. How can I run two independent transactions in parallel? Put differently, how can I make sure that two threads using this global transaction will not run in the same transaction?

By default, each thread has its own transaction. There isn't a notion of a global transaction.

4. What does TransactionService's getNonPropagatingUserTransaction() return?

A UserTransaction representing a new transaction for the current thread.

However, if I use this routine from my (non-Web Client) webapp once at the beginning of each web request then the Web Client asks me to log in again.

Transactions and authentication are two very independent concepts. You'll also need to authenticate the current thread. See AuthenticationService. On a single thread, you should 1) authenticate, 2) start trx, 3) do work, 4) end trx, 5) unauthenticate.

David, thanks for your reply. I see much clearer now.

Regarding my problem that the Web Client logs me out or complains about "transaction has already been marked for rollback", I'll try to find out more about what's going on and might get back later. Your clarifications have already helped me a lot!

I've tried to investigate further but could not find a solution.

David, can you think of any reason why the Web Client, running in a different webapp (and thus different thread) could throw an exception like the following?

I would be very glad to get some help; this seems to be quite deep in Alfresco where my flood lights fail!

Re: Basic question on transactions

hbf — Wed, 12 Dec 2007 13:53:26 GMT

Okay, it seems the problem was that my transaction in my (non-Web Client) webapp was closed in a rewinding and afterwards another call to the nodeService was made (without opening a transaction!).

This seems to cause the transaction of the Web Client to be used ("stolen") and resulted in the posted exception. Now that I only access the service when a transaction is open, everything works fine.

Thanks,
Kaspar

Sorry to come up with this again.

From time to time, I still get

Search failed due to system error: The transaction has already been marked for rollback‍

Can anybody explain where the origin for this might lie?

Thank you very much! I would be very glad to receive some help!
