index

One (1) or more for each index to which a selected record is connected. These are written for records retrieved through an area sweep, index, or set walk. If a selected record is both an entry record (or indexed through an entry index) and a selected owner or member of a selected set occurrence, multiple index extracts are written.

Review your Selection Criteria Specification to estimate the number of database records that will be extracted.

The Database Load Component creates a Workfile from the Extract File. You must allocate the same amount of space for the Workfile as the Extract File. The Workfile is also variable-blocked. The Database Load Component calculates the LRECL of the file for you with a BLKSIZE of 6144. You can override this block size.

Provide enough SORT SPACE capacity for the entire Workfile.
