PROPAGATE.DSNTYPE.EXTENDED= EXTPREF|EXTREQ

Edit online
When IBM® Connect:Direct® for z/OS® propagates the extended format dataset DSNTYPE (controlled by the receiver specifying PROPAGATE.DSNTYPE=YES in his INITPARMs), this parameter specifies which DSNTYPE value to use in DYNALLOC: EXTPREF or EXTREQ. Before IBM Connect:Direct 6.3, it was always EXTPREF.
  • EXTPREF - If the dataset cannot be created using the Extended Format attribute, it will be created without it, and so the allocation (and Process step) has a better chance of succeeding. This is the default and legacy behavior.
  • EXTREQ - If the dataset cannot be created using the Extended Format attribute, the allocation (and Process step) will fail.
Note: This parameter has no effect on the sending side. When specified on the receiving side it determines which of the two extended DSNTYPE values to use in a new dataset allocation.
