Abstract: High Availability Large Database (HALDB) allows an IMS database to grow to many terabytes. HALDB databases also provide increased availability by dramatically shortening reorganization times and allowing parallel processing of multiple partitions of a database. This is done without requiring changes to application programs. So, how do we migrate an existing IMS database to HALDB? This presentation describes the process and the options for doing this migration. Migrations of databases that were partitioned by other means are included. The use of IMS tools, including the HALDB Toolkit, is also explained.
