CA IDMS DMLO allows a single CA IDMS rununit to access data from different page groups using the mixed page group support feature.
This feature also permits a single rununit to access a database with segments that have been defined with a different maximum for the number of records that can be stored on a page. You can specify a different maximum for each page group.
You can define up to 32,767 different page groups. A single page group can qualify up to 16 million pages which significantly increases the size of a database that can be accessed from a single rununit. Furthermore, by allowing portions of a database to have different maximum records per page, you can use the available pages more effectively.
Exit 34 is provided for use with the mixed page group support feature. You can use this exit to help identify and correct applications that may require modification to function correctly when the mixed page group support feature is enabled. For more information about user exits, see the CA IDMS System Operations Guide.
