Performing an RMS SCT DBD (Database Definition) Overlay Import
Be sure you have a backup copy of your CDD before performing an overlay.
Once imported, you can overlay existing COBOL field names with the field names in your DBD. You can also use this overlay feature to add comments that correlate to the help screens in your application. Additionally, the comments contain the SCT mnemonic for each field, making it easy to locate a desired field using the CONNX Find feature. See SCT DBD Overlay Conventions for more information.
To perform an RMS SCT DBD overlay import:
1. Click Tools -> SCT DBD Overlay Import in the main CONNX Data Dictionary Manager window.
2. Select the check box in front of the modules you want to overlay.
If you wish, you can select the Import Comments Only check box to add only the DBD comments in your CDD. Importing comments only adds the mnemonic file and field identifier and any comments existing for each field in the DBD file.
By default, CONNX searches for "DBD".DAT in the $data directory for the module that is being overlaid. If applicable, select the Specify an alternate location of the DBD file check box and then type the location in the text box below. You can use wildcard characters in the file path.
3. Select the RMS database to overlay in the Database to Overlay text box.
4. Click the OK button.
5. Type the server name or IP address, a user name, and password in the corresponding text boxes on the Logon Information tab.
6. Set the port for this connection.
The default port is 6500. Any change made to the port setting in the text box becomes a permanent change to the port setting of the imported database. See Editing the OpenVMS Site-Specific Startup Command Procedure for more information.
7. Wait a few minutes - the conversion to DBD field names may take a while, depending on the size of the database.
Once the tables are converted, select a table from the list in the upper pane - the COBOL field names in the selected modules are converted to DBD field names. CONNX inserts comments containing a mnemonic code for each file and field and changes the field names.
