4.6. Transaction Wrapping Modes

ON

This mode always wraps every command in a transaction without checking whether it is required. This is the safest mode.

OFF

This mode never automatically wraps a command in a transaction or checks whether it needs to wrap a command. This mode can be dangerous as it will allow multiple source updates outside of a transaction without an error. This mode has best performance for applications that do not use updates or transactions.

DETECT

This mode assumes that the user does not know how to execute multiple source updates in a transaction. JBoss Data Virtualization checks every command to see whether it is a multiple source update and wraps it in a transaction. If it is single source then it uses the source level command transaction.
