Calculation of the space required for the DB2® tablespace and DB2 index for the transaction ID resource data.
To calculate the space, in KB, to allocate for the DB2 tablespace and the DB2 index required for transaction resource data, you need to estimate the total number of rows.
NUM_ROWS = (NUM_CICS_TRAN * 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.
Tablespace | Row_Size | Percent_Free | PRIQTY | SECQTY |
