Buffers for CA Disk I/O areas as well as memory tables for such items as member, alias, and note list entries are dynamically built. In some cases, CA Disk does not create variable length memory tables above the 16MB line. Since these items vary for each data set and device type being processed, exact storage requirements cannot be given.
Regions sizes on supplied JCL procedures range from 1024 to 5120K to accommodate running CA Disk with the maximum buffer space possible. The amount of region required below the 16MB line will vary depending upon the size of your catalogs, the number of your DASD volumes, and so on.
