Form Details

The FAIL.P2 procedure is used to purge failure statistics records from the data base. The criteria used to deterime which records are purged is based on a user defined cut-off date. All failure statisics records whose month and year designation is less than or equal to month and year of the cut-off date entered will be deleted. Because the MTBF calculation is based on historical data it is important to insure that a sufficient amount of data is available to provide a meaningful calculation. This determination will be dependent upon the established norms for your industry.

Frequency of Use
The frequency with which a purge is performed will vary depending on such factors as available disk space and the amount of on-line history desired. At a minimum purges should be performed on a yearly basis. Purging on a quarterly or even a monthly basis may be desirable if the volume of transactions is fairly high.

It is strongly recommended that a full account backup be performed prior to executing any purge process. It is also recommended that this be a permanent backup so that any records which were purged can be restored at a later date if required.
