The latest version and update content of the JOTM framework

JAVA Open Transaction Manager is a Java -based transaction management framework and is widely used in distributed transaction processing systems.It provides a method to achieve transaction consistency in distributed applications. The latest version of the JOTM framework is 2.1.11, released in 2021.This version mainly includes the following updates: 1. Improved XA (Extended Architecture) affairs support: JOTM 2.1.11 introduced better support for XA transactions. XA transactions are distributed transactions across multiple resource managers (such as databases). The following is an example of Java code created and processed XA transactions in JOTM: // Configure JOTM transaction manager TransactionManager tm = com.arjuna.ats.jta.TransactionManager.transactionManager(); // Create JOTM XA data source XADataSource xaDataSource = new MyXADataSource(); ConnectionFactory connectionFactory = new ManagedConnectionFactory(xaDataSource); // Starting transaction tm.begin(); try { // Get XA connection XAConnection xaConnection = connectionFactory.getXAConnection(); Connection connection = xaConnection.getConnection(); // Perform database operations in transactions // ... // Submit a transaction tm.commit(); } catch (Exception ex) { // Roll back transactions tm.rollback(); ex.printStackTrace(); } 2. Modified the log method: JOTM 2.1.11 introduced support for the new log frame, such as log4j 2.This modification improves the flexibility and performance of log records. The following is an example of JAVA code that configures JOTM using log4j 2: // Configure log4j 2 log recorder LoggerContext context = (LoggerContext) LogManager.getContext(false); context.setConfigLocation(new File("log4j2.xml").toURI()); // Configure jotm using log4j 2 log recorder Properties properties = new Properties(); properties.setProperty("java.util.logging.manager", "org.apache.logging.log4j.jul.LogManager"); System.setProperties(properties); // Initialize jotm transaction manager TransactionManager tm = com.arjuna.ats.jta.TransactionManager.transactionManager(); 3. Update the version of the dependent library: JOTM 2.1.11 uses the updated third -party dependency library version to provide better performance and security.For example, it uses the latest JDBC driver version and fixes some of the known problems. In summary, the latest version of the JOTM framework 2.1.11 has been improved and updated in XA transaction support, log methods and dependent library versions.Developers can build a more reliable and efficient distributed transaction processing system through these improvements.
