To manage space in an area, the DBMS keeps track of available space on each page. CA IDMS/DB reserves selected pages called space management pages (SMPs) for this purpose.
Space management pages
The first page in each area is an SMP; depending on the number and size of pages in the area, CA IDMS/DB can reserve additional SMPs throughout the area. When you determine the size of an area, you need to take into consideration the number of SMPs to be maintained in the area.
More information For more information on space management, see the CA IDMS Database Administration Guide.
