The default values set by CICS® IA are larger than required. To calculate the space to allocate for the DB2® tablespace and the DB2 indexes required for CICS region information, estimate the total number of rows.
In this example, the number of rows equals the number of CICS regions for which CICS IA data is being captured:
NUM of ROWS = Number of CICS regions
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 CICS region tablespace.
Tablespace | Row_Size | Percent_Free | PRIQTY | SECQTY |
