Space allocation for the EXTRACTS file depends on the number of errors detected during the audit phase and the size of the extract record. Determine the size of the extract record using this formula:
Record Size = 260 + length of longest symbolic key +
4 bytes for the record descriptor word (RDW)
Because it is difficult to estimate the number of errors, you can allocate the EXTRACTS file to tape. In a typical situation, a DASD cylinder allocation of 10,2 should be adequate.
