PH07271: DYNAMIC ALLOCATION OF CONCATENATED DATA SETS FAILED IN SOT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If allocation of more than 25 concatenated datasets is
  requested, that causes unpredictable results in SOT processing
  due to insufficient dataset checking.

  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  The DAI module builds a DD name list for the dynamic allocation
  interface in the work area. Since this DD name list has only 25
  entries, if allocation of more than 25 concatenated datasets is
  requested, that causes unpredictable results in SOT processing
  due to insufficient data set checking.
  

Problem conclusion

• The DAI modules have been changed to increase the number of
  entries in the DD name list to 60 and to check the number of
  concatenated data sets.
