Notes on transferring entire PO or PDSE data sets

• No file may exist with the same name as the temporary PS data set required ('transuid.podsname.U') in either of the two systems involved. Otherwise, the transfer request is rejected or canceled with an appropriate error message.

  A file with the same name as the temporary PS data set required
  ('transuid.podsname.U') may exist in the following case:

  An NCOPY command is issued under two different user IDs. The user ID of the TRANSFER-ADMISSION (transuid) and the partially qualified name (podsname) of the PO data set (as send or receive file) are identical in both commands. This is also the case if the name of the PO or PDSE data set is specified in its fully qualified form in each case, and only the "first level qualifier" is different (see above). The temporary PS data sets required then have the same name in both transfer requests. In this case, you should wait until the first transfer request is complete and then repeat your transfer request.

• The user ID (transuid) specified in the TRANSFER-ADMISSION must be authorized to create a file with the name of the temporary PS data set required
  ('transuid.podsname.U'). This may be rejected by RACF, for example, with the usual error messages.

• If the attempt to swap out the PO or PDSE dataset to a PS dataset using IEBCOPY-Unload fails on the send side, the transfer request is canceled with an error message.

• If necessary, you must make sure that the allocation for a PO data set that is to be received is sufficiently large. If a large number of members are to be entered then sufficient directory blocks must be available. If members are frequently replaced or extended then a PO data set should be periodically compressed.

• If there is not enough storage space in the receive system for the PS data set transferred, the transfer request is canceled and an error message is issued.

• If the attempt to create the PO or PDSE dataset from the transferred PS dataset using IEBCOPY-Load fails on the receive side, the transfer request is canceled with an error message.

  In this case, the transfer itself is already complete.
