Calculate the space required for the DB2® tablespace and DB2 index for Natural data.
To calculate the space, in KB, to allocate for the DB2 tablespace and the DB2 index required for Natural data, you estimate the total number of rows.
NUM_ROWS = (NUM_NATURAL_PROG * AVG_NATURAL *
PROG_TRAN_RATIO * NUM_REGION_D)
Use the value calculated for NUM_ROWS and the values for ROW_SIZE and PERCENT_FREE in Table 1 to calculate the PRIQTY and SECQTY as described in Figure 1 for the DB2 tablespace.
Tablespace | Row_Size | Percent_Free | PRIQTY | SECQTY |
