In the DB XA Module the TPM controls the login information. All such information is provided during the resource manager set up. Chapter 5 describes the information your programs need in order to establish connectivity to an XA-enabled database.

Opening and closing connections is not handled through the DB XA Module. As described in each of the access library descriptions in Chapter 5, the number of connections to the database is usually limited to a single connection (except with Sybase). If you convert a standard DB Interface Module program to one that uses the DB XA Module, you must take this change into account, or your code may result in notSupported errors. See Managing Connections for details.

Transaction Management is not handled through the DB XA Module. See Transaction Processing for details.
