Map and Table Load Module Occurrences

Establishing Load Modules

Load module occurrences in the data dictionary define modules that can be used by the CA IDMS/DB central version, CA IDMS, and CA ADS Load modules are stored in the DDLDCLOD area of the data dictionary. Map, table, and help load modules are established in the data dictionary in the following ways:

• The GENERATE clause of the ADD TABLE statement submitted to the DDDL compiler establishes a loosely coupled edit or code table as a load module in the data dictionary.
• The Compile action on the Main Menu establishes a map as a load module in the data dictionary.

  Note: The help load module is created when its corresponding map is compiled.

• The PROCESS=LOAD statement submitted to the CA IDMS batch utility establishes a map as a load module in the data dictionary.

Considerations

The following considerations apply to the modification or deletion of a load module:

• Once a load module has been stored in the data dictionary, only a user with ALL authority can delete the load module or have it punched to a SYSPCH file.
• When a previously loaded map load module is recompiled, the DCMT VARY PROGRAM map-name NEW COPY command must be used to ensure that the new version of the module is loaded in either of the following cases:
  • The batch utility is used to recompile the module.
  • MAPC is used to recompile the module and the OLM sysgen option NEW COPY IS N is defined for the online compiler.

  For either of the previously specified cases, if the DCMT VARY PROGRAM command is not used and the previous version of the map load module has not been deleted or overlayed, the old version of the map load module is used.

• When a map is recompiled and the sysgen option is NEW COPY IS N, the load module should also be varied NEW COPY.
• When a stand-alone edit or code table description is modified, it must be recompiled by the GENERATE option of the CA-IDD DDDL TABLE statement if the table load module is to reflect changes in the table definition.
• When a stand-alone edit or code table load module is modified, the map load module that uses that table as a linked table must be recompiled if it is to reflect changes in the table.
