Dynamic allocation

IMS HP Image Copy can dynamically allocate input and output data sets, such as database data sets, image copy data sets, log data sets, and change accumulation data sets. You do not need to provide a DD statement for each data set.

You can request dynamic allocation by specifying the following keyword parameters in the ICEIN control statement:
  • DBDALLOC=YES
  • DSDALLOC=YES
  • ICDALLOC=YES

You can omit the DD name for the data set which you want to dynamically allocate.

If you enable dynamic allocation, you can stack output data sets into a tape by specifying the STACK keyword.
