X/Open Standard Interface

In addition to the standard ODBC functions, the IBM Informix ODBC Driver also supports the following functions:

• _fninfx_xa_switch: Function for acquiring the xa_switch structure defined by Informix RM
• IFMX_SQLGetXaHenv: Function for obtaining the environment handle associated with an XA Connection
• IFMX_SQLGetXaHdbc: Function for obtaining the database handle associated with an XA Connection
• xa_open function takes an xa_info parameter. The IBM Informix ODBC Driver uses this xa_info to establish a XA connection

  The format of xa_info is as follows:

  <appilcationtoken>|<DSN name>

  The application token is a unique number the application generates for each xa_open request. It must use the same application token as parameter to IFMX_SQLGetXaHenv and IFMX_SQLGetXaHdbc to get the associated environment and database handles.

For information on programming with XA, refer to IBM Informix: TP/XA Programmer's Manual.
