CA IDMS/DB Reorg's Inputs

Database reorganization is a complex process. However, many of CA IDMS/DB Reorg's performance- tuning functions are performed automatically each time you run CA IDMS/DB Reorg. You need to supply only the inputs to CA IDMS/DB Reorg.

• Parameters --You supply input parameters to direct CA IDMS/DB Reorg, to indicate which subschemas and DMCLs are to be used for reorganization, and to indicate which areas are to be copied.
• Old and new subschemas and DMCLs--You define the old and new subschemas and old and new DMCLs to show what the database looks like before reorganization and what its characteristics are after reorganization occurs.
• Old database--You supply the old database--one that needs to be reorganized.
• Commands--You can enter status and control commands from the operator console while CA IDMS/DB Reorg is executing.
