ABSTRACT:
A system for modifying job control language (JCL) parameters optimizes data storage allocations for datasets by collecting historical data concerning actual data storage space requirements and use patterns for each dataset. JCL statements are parsed to find references to datasets and their requested data storage space allocations. The system then generates revised JCL statements with revised space allocation requests and dataset migration information for each dataset based on historical space requirements and usage patterns. Optionally, the system can display each proposed change to the JCL statements for approval by the user. The system can also revise JCL statements requesting allocation of space for each dataset in predetermined data storage areas grouped by predetermined size ranges. Alternatively, some operating systems include a JCL interpreter that translates JCL statements into control blocks having predetermined parameter fields. The present invention can be implemented to process and revise these JCL control blocks instead of generating revised JCL statements.
