What is 'transaction synchronization' in SAP BC-JAS - Java Application Server?

transaction synchronization - Overview

• Component: BC-JAS

• Component Name: Java Application Server

• Description: The mechanism which guarantees that a single transaction accesses a shared resource in a multithreaded environment. Java has a built-in synchronization mechanism - the "synchronized" keyword, but it is also possible to implement algorithms that will provide better performance in particular cases when synchronization is needed.

  Key Concepts: 
  Transaction synchronization is a feature of the BC-JAS Java Application Server that allows for the synchronization of multiple transactions. This means that multiple transactions can be executed in parallel, with each transaction being aware of the other transactions and their progress. This allows for better performance and scalability when dealing with large amounts of data. 
  
  How to use it: 
  Transaction synchronization can be enabled in the BC-JAS Java Application Server by setting the “transaction-synchronization” parameter to “true” in the server configuration file. Once enabled, transactions can be synchronized by using the “synchronize” method in the application code. This method will ensure that all transactions are aware of each other and will execute in parallel. 
  
  Tips & Tricks: 
  When using transaction synchronization, it is important to ensure that all transactions are properly synchronized. This can be done by using the “synchronize” method before any transaction is executed. Additionally, it is important to ensure that all transactions are properly committed or rolled back when they are finished.

  Transaction synchronization is a feature of many different application servers, including Oracle WebLogic and IBM WebSphere. Additionally, there are many different tools available for monitoring and managing transaction synchronization, such as Oracle Tuxedo and IBM WebSphere MQ.
