(PDF) Open nested transactions: Semantics and support

    https://www.researchgate.net/publication/229011200_Open_nested_transactions_Semantics_and_support
    The open nesting model [29] allows a transaction to commit and report its changes to the memory while being nested inside a transaction that has not committed yet. The key idea is to enable higher ...

Open Nested Transactions: Semantics and Support - CORE

    Abstract — We describe semantics for serializable (safe) open nested transactions. Given these semantics, we then suggest hardware necessary to support them directly. We further consider some useful, but not serializable, applications for open nesting, and their hardware implications.

Since these researchers have described their schemes using only operational definitions, however, the semantics of these systems have not been

We have also advocated for open nested transactions [15, 17] as a powerful extension to closed nesting, allowing improved concur-rency, at the cost of some programmer effort to program the neces-

Safe open-nested transactions through ownership

    https://dl.acm.org/citation.cfm?id=1504200
    The idea is to ignore ``low-level'' memory operations of an open-nested transaction when detecting conflicts for its parent transaction, and instead perform abstract concurrency control for the ``high-level'' operation that the nested transaction represents. To support this methodology, TM systems use an open-nested commit mechanism that ...Cited by: 26

Does Hibernate support nested transactions? - Stack Overflow

    https://stackoverflow.com/questions/33180558/does-hibernate-support-nested-transactions
    While Hibernate does not explicitly support nested transactions, using a JDBC 3.0 driver that is able to create savepoints can achieve this. Create a Connection at the start of the program when the SessionFactory is created. At this point you also create a Savepoint that …

Memory Models for Open-Nested Transactions

    http://publications.csail.mit.edu/abstracts/abstracts07/sukhaj/sukhaj.html
    Open-nested transactions have been proposed as a loophole [6] for transactional memory (TM) to increase concurrency on highly contended resources in transactional programs. Programs that use open nesting can be difficult to reason about because open nesting …

c# - Using "nested" transactions in oracle - Stack Overflow

    https://stackoverflow.com/q/24506847
    Oracle doesn't support nested transactions. If a transaction commits, it commits. That's why you generally don't want to commit (or rollback) a transaction in a stored procedure, that makes it difficult to reuse the procedure elsewhere if your transaction semantics differ.

Open Nested Transaction: A Support for Increasing ...

    https://dl.acm.org/citation.cfm?id=646202.681990
    This paper describes an extension of the OMG's Object Transaction Service, by adding the "open nested transaction model", which greatly improves transaction parallelism by releasing the nested transaction locks at the nested transaction commit time. Open nested transactions relax the isolation property by allowing the effects of the committed ...Cited by: 5
