For transaction dumps, use extended format sequential data sets
because they have the following characteristics:
- Greater capacity than sequential data sets
- Striping and compression support.
For more information on extended format sequential data sets,
see
Choosing SVC dump data sets.
Sequential data sets can use large format data sets (DSNTYPE=LARGE).
Extended format sequential data sets can be placed in either track-managed
space or cylinder-managed space. Transaction dump fully supports placing
dump data sets in cylinder-managed space.
