We have a project running loads against 6 tables that have 53 parts each.
We are using SMS to manage the datasets and the DASD is defined EA-enabled
and the data class is defined to allow the datasets to span 5 volumes. It
seems like DB2 is overriding the data class and not allowing the dataset to
jump to the next volume to get additional extents. We have been working on
this all weekend and have done an IDCAMS ADDVOLS to each dataset - which
worked until the load ran and the five volume allowance disappeared. Is
there something within DB2 that could be overriding the SMS data class and
if so what? Or is there some kind of quirky thing between DB2 and SMS?
