Chapter 4. JDBC Transactions
4.1. JDBC Transaction Types
The JBoss Data Virtualization JDBC API supports three types of transactions from a client perspective:
- global transactions,
- local transactions, and
- request level transactions.
All are implemented by JBoss Data Virtualization as XA transactions. Refer to the JTA specification at http://www.oracle.com/technetwork/java/javaee/tech/jta-138684.html for more information on XA Transactions.
Warning
The use of global, local, and request level transactions are all mutually exclusive. Request level transactions only apply when not in a global or local transaction. Any attempt to mix global and local transactions concurrently will result in an exception.
