Issue/Introduction

In Gen 8.6, when compiling an Action Block, developers can see in the COBOL generated source file this statement within the flower box: "Enforce default values with DBMS not selected" but in the same generated source file, the developer can see that the target DBMS is DB2 z/OS. How is that possible?

In Gen 8.0 and prior, this behavior did not occur, i.e. the developer did not see the statement "Enforce default values with DBMS not selected". 

Here is an example of the generated COBOL source code flower box from an Action Block in Gen 8.6:

* Name: Test_module1 Date: 2016/09/01
* Target OS: MVS Time: 12:15:00
* Target DBMS: DB2 z/OS User: abc123              <------
*
* Generation options:
* Debug trace option not selected
* Data modeling constraint enforcement not selected
* Optimized import view initialization not selected
* High performance view passing selected
* LAST-STATEMENT-NUM execution selected
* Enforce default values with DBMS not selected   <------

Resolution

A change was made in Gen 8.5 and is also in Gen 8.6. If the Toolset Technical Design checkbox "Enforce Default values within DBMS" is unchecked, then we set the flower box message as follows: "Enforce default values with DBMS not selected".  In Gen 8.0, the message was incorrectly set to "Enforce default values with DBMS selected" whether this checkbox was checked or not. 

In Toolset Technical Design Properties for your database, there is a "Referential Integrity Enforced by" dropdown that may be set to DBMS and then there is a checkbox "Enforce Default values within DBMS" that may not have been checked.  By Checking this checkbox and regenerating the action block, the generated flower box displays the correct message of "Enforce default values with DBMS selected."

Additional Information: 

There were changes introduced in Gen 8.5 via PTF GEN85001 that affected the generators in this area. What customers could be seeing, the 'Enforce default values with DBMS' line in the flower box of the generated code, was a fix via this PTF and was also in the initial release of Gen 8.6. We now generate the correct value for the 'Enforce Default Values...' setting in the Technical Design.
