Catalogs and Record Layouts

Catalogs organize associations between legacy assets and the copybooks or source definitions that describe their data structures.

Open Catalog from the top navigation. Each host appears as a collapsible section with tabs for its catalog-enabled endpoints, such as CICS, IMS, IMS-DB, IMS-DLI, Datasets, DB2, AS400 RPC, and Models.

The IMS-DB tab has inner tabs: Record layouts, Table APIs, and Flows. DB2 tabs list generated table API definitions. Other tabs show a record-layout report.

Reports let you filter associations, inspect layouts as a field tree or JSON, approve or mark layouts pending, push selected associations to Hub, and delete selected associations.

Associations are created from Browse (Populate from CICS / IMS), transaction testing, dataset content, IMS-DB queries, IMS-DB / DB2 Populate APIs, and JT400 programs.

Published items appear in the Dynamic OpenAPI spec. See Published REST APIs for paths and authentication.

Administrators can create, rename, delete, and assign catalogs through the Admin panel. A catalog in use by an endpoint cannot be deleted.
