XA-Compliant Data Sources and Data Source Types

3 An XA-compliant data source type is a 3type of data source that is capable of supporting XA protocol requirements 3for a resource manager that is participating in a transaction.

A data source is an instance of a data 3source type. An XA-compliant data source must be created in each 3database in which you want it, and the data source must be registered 3into the transaction manager when it participates in the transaction.

The transaction manager maintains a list of XA data sources participating 3in each transaction. Each XA data source participating in each transaction 3must dynamically register itself with the transaction manager by 3calling the mi_xa_register_xadatasource( ) or ax_reg( ) function 3at least once per transaction. If, for some reason, the XA data 3source does not participate in the two-phase commit protocol, it 3can be unregistered by calling the mi_xa_unregister_xadatasource( ) or ax_unreg( ) function.
