Abstract: IMS Version 7 adds High Availability Large Database (HALDB) capabilities. In general, application programs do not have to be modified when a database is migrated to HALDB. On the other hand, there are cases where application programs must be changed. Also, an installation may want to take advantage of some capabilities which may require application changes.
This presentation describes changes that you may need to make or want to make when a database is migrated to HALDB. Considerations for processing partitions in parallel, processing secondary indexes as databases, initially loading HALDB databases, handling unavailable partitions, and converting from user partitioning are explained.
Extensive notes are provided.
