Idea created for BMW BAYERISCHE MOTORENWERKE AG

 

Even if a NON VSAM data set is not restored because of PREALLOCn or a VSAM Data Set is

not restored because of VSPREDEFn, the Archive tapes are mounted, causing an unnecessary overhead.

Especially during RECOVER, if a lot of data sets already exists on DASD and should not be replaced.

PREALLOCn or VSPREDEFn should be checked first and only if it is determined, that the data set

does not exist and it actually will be restored, then the tapes should be mounted.
