Reorganization Controlled by Internal Logic

Many CA IDMS/DB Reorg reorganization functions are directed by internal processing logic. They occur automatically, whenever you invoke CA IDMS/DB Reorg and identify an area to be reorganized; you do not need to supply parameters or changes to the definition of the subschema. CA IDMS/DB Reorg's internal processing logic automatically provides these reorganization functions:

• Optimize CALC sets
• Optimize VIA sets
• Minimize fragmented records
• Eliminate logically deleted records without executing additional utilities
• Retarget relocated records to their home pages
• Maintain order of all CALC records
• Store records in true physical sequential order
