Load Module Scanner tables

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 the Load Module Scanner, estimate the total number of rows.

In this case, there are two tables:
CIU_SCAN_SUMMARY
The number of rows for this table is the number of programs that contain Affinity or Interdependency commands from all the application load modules.
CIU_SCAN_DETAIL
The number of rows for this table is the number of programs defined for the CIU_SCAN_SUMMARY multiplied by the average number of EXEC CICS commands per program.

To obtain these values, run the Load Module Scanner in report mode only; that is, run CIUJCLLS and CIUJCLLD.

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 DB2 space allocation for the Load Module Scanner tablespace.
