Including a schema in a program view

When defining a schema, also known as a program communication block (PCB), to a program view use the CREATE SCHEMA clause. The CREATE SCHEMA must be specified as a clause within the CREATE PROGRAMVIEW statement.

The schema represents message destinations or database resources used by the application program. One or more are usually included, however are not always required. For example, a message switching program or conversational message program might not require access to a DL/I database.

The maximum number of schemas that can be defined for a given program view is 2500. This is the maximum value for application programs executing in all IMS™ region types (MSG, DL/I, and so on).
