JBoss Data Virtualization uses XA transactions for participating in global transactions and for demarcating its local and command scoped transactions. Refer to the Red Hat JBoss Data Virtualization Development Guide Volume 1: Client Development for more information about the transaction subsystem.
| Scope | Description |
|---|---|
| Command | Treats the user command as if all source commands are executed within the scope of the same transaction. The AutoCommitTxn execution property controls the behavior of command level transactions. |
| Local | The transaction boundary is local defined by a single client session. |
| Global | JBoss Data Virtualization participates in a global transaction as an XA Resource. |
The default transaction isolation level for JBoss Data Virtualization is READ_COMMITTED.
