Working with metadata
The metadata that application programs require to access IMS databases is often split between two sources: the database descriptor (DBD) that is stored in IMS and the application program metadata source that is typically stored outside of IMS in COBOL copybooks or PL/I include files. By using IMS™ Explorer, you can consolidate and publish this metadata for distributed access.
About this task
To consolidate the metadata, you import both the DBD metadata and the application program metadata into IMS Explorer and then export the consolidated metadata in two formats: a compressed file for use by the application programs and DBD and program view (PSB) source for inclusion in the IMS catalog, which becomes the single, trusted source for the metadata.
