Allocating Space for DASD Files

CA IDMS Extractor requires space allocation for an Extract File, a Workfile, a Communication File, a Syntax File, and sort work files. The Syntax and Communication Files are fixed at one track apiece. Space allocation for a DASD Extract File is dependent on the number of database records extracted and on the number of set occurrences in which those records participate as either owner or member. The table below displays the type and number of extracts created and written to the Extract File. The work file and total sort work space require the same amount of space as the Extract File.
