Estimate the Storage Requirements

Estimate the amount of space that is required for each CA Datacom/AD unload format data set populated by the conversion utility. Because these data sets can contain large amounts of security data, allocate each data set with enough space to allow conversion utility processing to complete successfully.

Use the following equation to estimate the amount of space that is needed for each output data set:

The maximum count of a CIA table record type generated x [maximum CIA table record length (3,157 bytes) / 849,960 bytes = ______________ Total space (in cylinders)

Follow these steps:

1. After running the CIAUNLD CIA unload utility, review the output Statistical Report to find the maximum count of a CIA table record type generated in the CIA UNLOAD DD data set.
2. Multiply the maximum count of a CIA table record type generated by the maximum CIA table record length (3,157 bytes) to determine the maximum number of bytes of storage required for each CIA output data set.
3. Divide the total number of bytes of storage required by the number of bytes on a cylinder for the hardware disk model you are using.

You have determined the total number of cylinders of space to allocate for each CA Datacom format unload data set.
