Step 3—Prepare the Physical CA IDMS/DB Database

In this step you prepare physical CA IDMS/DB DDL statements. These statements describe the physical component of the CA IDMS/DB database. The physical component includes:

• Segments—collections of files and areas
• Database name table—names of databases and segments
• Device-media control language (DMCL)—buffers, journals, identification of a database name table, identification of segments for inclusion in the database, file overrides, and area overrides.

Note: For more information about the syntax for CA IDMS/DB physical DDL statements, see the CA IDMS Database Administration Guide. For information about the CA IDMS Command Facility which you use to submit physical DDL statements, see the CA IDMS Common Facilities Guide.
