The format of the OSCNTL file is unchanged. If your installation's existing OSCNTL file contains installation-defined ASN.1 maps, you must recompile them in the r12 product region.
Ensure the data set containing the map source is added to the COMMANDS concatenation in your new region. To compile a map, use the Compile Map option of Mapping Services. To access the Mapping Services Primary Menu, enter /MAPMENU from any panel.
Note: For more information about Mapping Services, see the Managed Object Development Services Programming and Administration Guide.
