CA Datacom/AD Space Sizing Considerations

The CA Datacom/AD database files are sequential files allocated in install job WRDCM$04. The database tables are in eight files. Each table has an associated table ID that CA Datacom/AD uses to reference it. The following tables show the allocations supplied in cylinders for the production (500) database. Also, there is an approximation of how many rows each table holds when fully extended, based on these allocations. Job WRDCM$04 allocates the files with the following space allocations:

Table ID (Name)

Primary

Secondary

Rows

NO 7 (RESOURCE)

20

20

About 14000

NO4 (NUMERICFACT)

240

40

About 8000000

NO2 (ENUMERATEDFACT)

30

5

About 112500

NO6 (PERIOD)

5

1

About 105000

Note: The tables above will grow and extend in your database.

Table ID (Name)

Primary

Secondary

Rows

NO 1 (ATTRIBUTE)

1

1

About 320

NO8 (TIMEFRAME)

1

1

About 25

NO5 (PERFORMANCEAGENT)

1

1

About 6

NO3 (KEYRANGE)

1

1

About 4

Note: The tables will not grow beyond the supplied values in your database.

The NUMERICFACT table will expand the most. The supplied PRIMARY allocation of 240 cylinders and the SECONDARY allocation of 40 cylinders will allow this table to hold approx. 8,000,000 records when the file has expanded to its allowable 16 extents. This is based on the following formula:

240 3390 cylinders = approx. 2250000 records  
40  3390 cylinders = approx. 375000  records

You can increase the PRIMARY and SECONDARY allocations for the NUMERICFACT table to suit your requirements.
