Testing the Access Module

Which Access Module Executes

The default access module that is executed at runtime is the access module associated with the program that issues the first SQL statement executed within the SQL session.

A program is associated with an access module when the program is precompiled.

Note: For more information about associating a program with an access module, see Precompiling the Program.

There are two ways to override at runtime the access module default that is set at precompile time:

• The program issues a SET ACCESS MODULE statement before the database transaction begins

  Note: For more information about using the SET ACCESS MODULE statement, see Preparing and Executing the Program.

• A different version of the access module is used because a test version option has been set for the DC session in which the program is executing

Test Versions

If there is a version of the access module that matches the test version setting, the matching version is executed. If an access module with a matching version is not found at runtime, version 1 of the access module is executed.

Note: For more information about test versions, see documentation of DCUF TEST in the CA IDMS System Tasks and Operator Commands Guide.
