ARIES/NT: A Recovery Method Based on Write-Ahead Logging for Nested Transactions

by Kurt Rothermel, C. Mohan , 1989
"... A simple and efficient recovery method for nested transactions, called ARIES/NT (Algorithm for Recovery and Isolation Exploiting Semantics for Nested Transactions), that uses write-ahead logging and supports semantically-rich modes of locking and operation logging is presented. This method applies t ..."

to a very general model of nested transactions, which includes parlial rollbacks of subtransactions, upward and downward inheritance of locks, and concurrent execution of ancestor and descendent subtransactions. The adopted system architecture encompasses aspects of distributed data base management

D-ANTICIP: a Protocol Suitable for Distributed Real-Time Transactions

by Bruno Sadeg, Samia Saad-bouzefrane, Laurent Amanton
"... Keywords: Real-time, distributed database, subtransaction, commit processing, firm deadline Abstract: Many problems arise when we address issues on distributed real-time database systems (DRTDBMSs). A distributed database consists in general of a database located in a main site, the master, where is ..."

their deadlines in comparison with the traditional ¢¤£¦ ¥-§©¨���������¥������� ¢ protocol. a because the protocol anticipates that the transactions will be aborted or committed, then it aborts useless subtransactions in descending order, beginning at the tree root (see section 4) 1
