We have 2 large files that we are trying to obtain a good 
estimate on the time required for File Reorganization.  Each 
of the files have 6 dependent logicals for reindexing, and we 
have only a 6 hour window weekly in which to complete the 
reorg within a dedicated environment.

Total records     . . . . . . .   . . . . . . . :        14482827
Total deleted records  . . . .. . . . . . . :        19562233
Total of member sizes  . . . . . . . . . :      1533073408

Total records  . . . . . . . . . .     .  . . :         94597420
Total deleted records  . . . . . ... . .   :         33819548
Total of member sizes  . . . . . . . . . :      4257355776

Does anyone know the IBM Pub or Redbook in which the 
formula is contained to calculate this estimate based upon 
system, processor, storage, DASD, disk arms, etc ?

Thanks in advance for your reply.
