block where the last record of the transaction modification was recorded. This enables Oracle to find the last undo record generated by the transaction when the crash is resumed, so that it knows where to start processing the rollback.Nub represents the number of undo blocks used by the current transaction. When a transaction is rolled back, you can see that the value is progressively reduced.The CMT represents the closest commit timestamp, which is

programming transaction management of the JTA interface and the declarative transaction management based on the application server.Spring's transactional framework separates the concerns related to transaction management in the development process and makes a reasonable abstraction of these concerns, ultimately creating a convenient yet powerful transaction management " weapon." With spring's transactional framework, we can do transactional programming according to a unified programming model,

the JDBC driver documentation) The Java EE application queries the data source with JNDI.　　Once the application finds the data source object, it calls Javax.sql.DataSource.getConnection () to get a connection to the database. XA connections are not the same as non-XA connections. Be sure to remember that the XA connection participates in the JTA transaction. This means that the XA connection does not support the auto-commit feature of JDBC. Also, the application must not call Java.sql.Connectio

a jndi-based, fairly complex API implementation. Relative coding implements JTA transaction management, and we can accomplish the same function through the container transaction management mechanism (CMT) provided by the EJB container, which is provided by the Java EE Application Server. This allows us to simply specify which method to join the transaction, and once specified, the container will be responsible for the transaction management task. Thi

connections are not the same as non-XA connections. Be sure to remember that the XA connection participates in the JTA transaction. This means that the XA connection does not support the auto-commit feature of JDBC. Also, the application must not call Java.sql.Connection.commit () or Java.sql.Connection.rollback () on the XA connection.Instead, applications should use Usertransaction.begin (), Usertransaction.commit (), and Sertransaction.rollback ().3.
