Performing a VSAM SCT DBD (Database Definition) Overlay Import - MVS-OS/390
You can overlay the imported COBOL FD field names in your CONNX CDD with the corresponding FOCUS™ DBD names. You can also use the CONNX SCT DBD Overlay Import feature to add comments that correlate to the help screens in your application. In addition, the comments contain the SCT mnemonic for each field, making it easy to locate a desired field by using the CONNX Find feature.
See Importing from VSAM COBOL FD Files (CICS) - MVS z/OS for information on how to authorize and verify FTP access.
1. Click the Import button in the CONNX CDD Windows Application window.
2. Select VSAM SCT COBOL FD files in the Import Type list box.
3. Type an SCT COBOL FD partitioned data set and member name in the Enter an SCT COBOL FD data set member text box.
For example, to import the SCT AAFILE, enter SCT.SISBASE.SOURCE(ACAARC).
4. Fill in the necessary logon information if it's not imported automatically from the SIS files.
5. Click the OK button to import the SCT layouts.
The process may take a few minutes depending on the number of imported files.
6. Click Tools -> SCT DBD Overlay Import in the main CONNX Data Dictionary Manager window.
7. Select the Import Comments Only check box to add only the DBD comments currently in your CDD.
Importing comments only adds the mnemonic file and file identifier and any comments existing for each field in the DBD file.
8. Select the Specify an alternate location of the DBD file check box and then type the location in the text box below.
It is not necessary to have the "DBD".DAT files in order to import from an OS/390 system. Given the default SCT installation prefixes, the SCT Focus DBD sequential overlay files are:

SCT.ADSBAS.XEDS004 | Alumni Development System
SCT.FRSBASE.XDS002 | Financial Records System
SCT.HRSBASE.XDS003 | Human Resource System
SCT.LMSBASE.XDS005 | Loan Management System
SCT.SISBASE.XDS001 | Student Information System
SCT.ZSSBASE.XDS000 | Z Support Software System

9. Select the VSAM database to overlay in the Database to Overlay list box.
10. Click the OK button.
The conversion to FOCUS field names may take a few minutes, depending on the number of imported files.
Once the files are converted, select a table from the list in the upper pane. The COBOL field names in the selected modules are converted to FOCUS field names. CONNX inserts comments containing a mnemonic code for each file and field, and changes the field names.
Note:
Partial (for example AC*) or complete (*) wildcard characters may be used in place of a file name during import.
