Implementing External Action Blocks › Construction › Generation

Generation

Generation comprises tasks that can take place on a workstation Toolset, CSE Construction Client, or from Host Construction, and tasks that must be performed outside the CA Gen software.

The following tasks are performed using CA Gen:

• Resolve DBRM
  • Workstation toolset—If the external action block contains SQL and the target DBMS is DB2, its DBRMs must be resolved. External Action Block DBRMs are resolved by the Generation Function on the workstation, not on the z/OS IT. To resolve External Action Block DBRMs, select Design, then Action Diagram. Highlight the action diagram name you want and select Detail, External Properties, Add. Input the DBRM name you want, select Close, and then package and generate the remote file as usual. This creates the tokens necessary for the z/OS IT to include the DBRM during the BIND.
  • Host Construction—If the External Action Block uses embedded SQL and the target DBMS is DB2, CA Gen must be given the names of any database request modules (DBRMs) associated with the External Action Block. The External Action Block Resolution panel is used to identify any DB2 DBRMs for an External Action Block. The panel can also be used to change the name of the External Action Block member. (The member name is the name of the load module that contains the External Action Block.)
• Generate stub

The following tasks are performed outside of CA Gen:

• Locate the External Action Block Stub
• Customize the appropriate external action logic
• Compile the External Action Block
• If the External Action Block is statically called by a module marked for Compatibility the EAB must be compiled with the NODLL compile option, if not the EAB must be compiled with the DLL compile option.
• Link into an External Action Block library

  Note: This library must be a data set that has been created as a PDSE (type=library) data set.
