# of EXTRACT records = (# of EXTRACT records/record type (see note)) * (# of occurrences of that record type). The CA IDMS/DB Analyzer Set Report lists the number of member record occurrences (for member records) and the number of set occurrences (for owner records). Extract records are not created for index pointers. |

PRIOPTA |

23 + length of longest CALC key in copy area |
Multiple of LRECL closest to 6K. |
# of PRIOPTA records = (CALCs + DIRECTs + VIAs) whose page range is the same as their owner's page range (see note). The length of the longest CALC key in any copy area must be added to the fixed length portion to determine the total length of a PRIOPTA record. (See CA IDMS/DB Reorg message NLYZ007I in ANALYSIS Step). Note: Refer to Audit Subreport--Set Linkage Recap for Area for additional information |
|
SECOPTA |
FB |
The greater of 34 or (34 + length of longest integrated index symbolic key) (See message NLYZ012I in ANALYSIS Step). |
Multiple of LRECL closest to 6K. |
# of SECOPTA records = (# of VIAs not in the same page range as the owner) + (# of all BL SR8 records) |
