Disk Retention Parameter Guidelines

Specifying the amount of retention in days with the DRETPD parameter for disk and RETPD parameter for tape clarifies the effect of the ERO table on a report's retention—it will be kept for nn days. Specifying the DRETPD parameter is the most efficient processing method, because CA View can use a simple arithmetic calculation on the archival date.

We recommend that you specify the following disk parameters with the corresponding tape retention:

Note: If you do not specify a disk retention parameter, disk retention is the same as the tape retention. If you specify disk retention, but not tape retention, tape retention will be the same as disk retention. If you specify both tape and disk retention, that is. RETPD=5 DRETPD=10, tape retention will be changed to the larger value, in this case 10.
