7.6 Indirect CALC page
Indirect CALC pages are created for a record type stored with LOCATION MODE IS CALC
if the record type was simultaneously defined with the SSL as one of the following:
– as a member with MODE IS LIST or
– with PLACEMENT OPTIMIZATION or
– with COMPRESSION FOR ALL ITEMS.
Indirect CALC pages are always set up when SEARCH KEY USING CALC has been
specified.
Depending on which page length was defined for the database, the length of an indirect
CALC page may be 2048 bytes, 4000 bytes or 8096 bytes.
Indirect CALC pages with a length of 2048 bytes differ from those consisting of 4000 or
8096 bytes with respect to the lengths of entries for the record sequence number (RSQ):
– In the case of indirect CALC pages with a length of 2048 bytes, the RSQ entry is 3 bytes
long.
– For indirect CALC pages with a length of 4000 or 8096 bytes, the RSQ entry is 6 bytes
long.
The structure of indirect CALC pages differs from that of direct CALC pages in that they
contain no records or page index entries. The CALC table line therefore contains the PPP
to the associated record. In every other respect, the description of the direct CALC page
also applies to the indirect CALC page.
