Adding PEP to real-time distributed commit processing

J.R. Haritsa, K. Ramamritham
Proceedings 21st IEEE Real-Time Systems Symposium  
One-phase commit protocols substantially reduce the overheads of transaction commit processing, making them attractive for incorporation in distributed real-time databases.  ...  We present here a new one-phase real-time commit protocol, called PEE that addresses the above-mentioned problem by suitably utilizing our previously proposed prepared data borrowing technique.  ...  We compare their performance with that of PROMPT, the state-of-the-art in real-time commit processing.  ...

A survey of Commit Protocols in Distributed Real Time database systems

Fadia A. Elbagir, Ahmed Khalid, Khalid Khanfar
2016 International Journal of Computer Trends and Technology  
The commit processing in a Distributed Real Time Database (DRTDBS) can significantly increase execution time of a transaction.  ...  Therefore, designing a good commit protocol is important for the DRTDBS; the main challenge is the adaptation of standard commit protocol into the real time database system and so, decreasing the number  ...  The transaction in a real time database system has deadlines to process the workloads and it need to process transactions before these deadlines expired [3] .  ...

Reliable transaction processing for real-time distributed database systems

Yong I Yoon, Song C Moon
1992 Microprocessing and Microprogramming  
All previous commit protocols, however, fail to provide the timeliness for real-time processing.  ...  When real-time applications require distributed transaction processing, both correct completion and timeliness should be satisfied.  ...  We descdhe these latter two commit protocols and their problems because only they are concerned with the real-time processing.  ...

A real-time database for future telecommunication services [chapter]

T. Niklander, J. Kiviniemi, K. Raatikainen
1997 Intelligent Networks and Intelligence in Networks  
The current Intelligent Network (IN) Recommendations of ITU-T imply that real-time transaction processing capabilities should be provided.  ...  The most challenging issue in designing a real-time transaction processing system for telecommunications is the handling of transactions in three categories having very different characteristics.  ...  In the RODAIN data model we defined real-time objects and real-time characteristics.  ...

Verifying Real-time Commit Protocols Using Dense-time Model Checking Technology [article]

Omar I. Al-Bataineh, Mark Reynolds
2018 arXiv   pre-print
The paper considers the verification of real-time distributed commit protocols using dense-time model checking technology.  ...  More precisely, we model and verify the well-known timed two phase commit protocol in three different state-of-the-art real-time model checkers: UPPAAL, Rabbit, and RED, and compare the results.  ...  For example we might have situations in the protocol where process i commits at real-time 10, process j commits at real-time 15, and process k commits at real-time 20.  ...

A real time distributed computing has heterogeneously networked computers to solve a single problem. So coordination of activities among computers is a complex task and deadlines make more complex.  ...  This leads to design of a new distributed commit-processing protocol to have a real-time committing performance.
