Using Other Database Managers

You can access other, non-XA-compliant databases through . The recommended method is to use the exit program DFHUSYNC. A sample exit program is supplied as dfhusync.cbl, located in %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\src\enterpriseserver\exits (Windows) or $COBDIR$COBDIR\cpylib (UNIX). Follow these steps to customize the sample exit program:

1. Add code to be invoked at any or all of the following points:

   • SEP initialization

   • The start of a CICS task

   • When rollback is required

   • When a prepare is required for a syncpoint

   • When a commit is required

   • SEP shutdown

     This code should invoke the appropriate actions from the database manager being used. If you want to enable commit and rollback processing (two-phase commit), include the SQL Communications Area (SQLCA) in the Working-Storage Section of the dfhusync.cbl module.

2. Run dfhusync.cbl through the appropriate SQL preprocessor.

3. In Enterprise Developer, compile dfhusync.cbl to any callable format. Do not use the CICS preprocessor.

4. Put the compiled module in %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\bin and \bin64 (Windows) or $COBDIR/lib (UNIX). This replaces the default file supplied with MSS.
