Read this short, 150-page book that is adapted from \u003cem\u003eExpert Oracle Database Architecture\u003c\/em\u003e to gain a solid and accurate understanding of how locking and concurrency are dealt with by Oracle Database. Also learn how the Oracle Database architecture accommodates user transactions, and how you can write code to mesh with how Oracle Database is designed to operate.\u003c\/p\u003e\u003cp\u003eGood transaction design is an important facet of highly-concurrent applications that are run by hundreds, even thousands of users who are all executing transactions at the same time. Transaction design in turn relies upon a good understanding of how the underlying database platform manages of the locking of resources so as to prevent access conflicts and data loss that might otherwise result from concurrent access to data in the database.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eOracle Database Transactions and Locking Revealed\u003c\/em\u003e covers in detail the various lock types, and also different locking schemes such as pessimistic and optimistic locking. Then you’ll learn about transaction isolation and multiversion concurrency, and how the various lock types support Oracle Database’s transactional features. You’ll learn some good tips for transaction design, as well as some bad practices and habits to avoid. Coverage is also given to redo and undo, and their role in concurrency. This is an important book that anyone developing highly-concurrent applications will want to have handy on their shelf.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003eWhat you’ll learn\u003cul\u003e\n\u003cli\u003eUnderstand locks and their implication for concurrent applications\u003cp\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eManage transaction isolation to meet business needs while not impeding concurrency\u003cp\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesign effective transactions and choose the correct atomicity level for your needs\u003cp\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eTake advantage of features such as deferrable constraints and autonomous transactions\u003cp\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eBuild multi-database applications with needed atomicity through distributed transactions\u003cp\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eInvestigate and troubleshoot redo and undo problems that can impede concurrency\u003cp\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003eWho this book is for      \u003cp\u003e     \u003cem\u003eOracle Database Transactions and Locking Revealed\u003c\/em\u003e is the definitive book on transactions and locking for Oracle Database developers and architects who are developing highly-concurrent applications.
