To browse or edit your databases in the IMS/DC or CICS environment, the databases’ Data Base Definition (DBD) information must be made available to File-AID. File-AID maintains an online CLT control database to store information about your databases’ segment definition and hierarchy.
The Batch DBD Update Facility retrieves the DBDs you specify from your DBD load library, extracts and formats relevant information, and updates this information to the CLT control database for use by online File-AID programs.
You need to run the DBD Update Facility when:
- A database needs to be accessed in File-AID. The database’s DBD information must be added to the CLT control database.
- A DBD has changed. For example, segments are added to or deleted from a DBD. These changes must be reflected on the CLT control database.
- A DBD no longer exists. This reference must be deleted from the CLT control database.
In addition to storing DBD information, the DBD Update Facility enables you to specify a 30-character DBD description. The description is also stored in the CLT control database and displayed on the DBD Member List screen in File-AID to make it easier for you to determine the appropriate database to process.
To browse or edit databases in Formatted mode using your existing segment layouts as templates over the segment’s data, the Cross-Reference Update program must be run to allow File-AID access to these layouts. For more information, see Batch XREF Update Facility.
