PI67757: POTENTIAL FTP FAILURE WHEN TRANSFERRING A LARGE LOAD LIBRARY

APAR status

• Closed as fixed if next.

Error description

• .
  Attempting to transfer a very large Load Library data set (PDS
  or PDS/E) using between z/OS systems using FTP functions GET or
  PUT with EBCDIC type and BLOCK or COMPRESS mode (or the
  equivalent MVSGET or MVSPUT functions).  The potential exists
  that the size of the temporary data set used to hold the IEBCOPY
  unload version will far exceed the available DASD space.  The
  following messages may be generated:
  
    IKJ56893I UTILITY DATA SET NOT ALLOCATED+
    IGD17273I ALLOCATION HAS FAILED FOR ALL VOLUMES SELECTED FOR
              DATA SET SYSyyddd.Thhmmss.RA000.userid.Rnnnnnnn

              ENABLED OR QUIESCED
    IGD17290I THERE WERE i CANDIDATE STORAGE GROUPS OF WHICH THE
              FIRST j WERE ELIGIBLE FOR VOLUME SELECTION.  THE
              CANDIDATE STORAGE GROUPS WERE: ....
    IGD17279I mm VOLUMES WERE REJECTED BECAUSE THEY WERE NOT
              ONLINE
    IGD17279I nn VOLUMES WERE REJECTED BECAUSE THE UCB WAS NOT
              AVAILABLE
    IGD17279I ss VOLUMES WERE REJECTED BECAUSE OF A DADSM FAILURE
              (044E0097)
  

Local fix

• .
  Run the IEBCOPY unload step outside of FTP.  Then use a EBCDIC
  type and BLOCK or COMPRESS mode transfer on the unloaded data
  set, and perform the IEBCOPY load on the target system.

  ****************************************************************
  The problem can be summarized as follows:
  When a FTP client tries to transfer a very large load library
  (PDS/PDSE) using FTP mvsput/mvsget, it may fail. FTP client will
  receive an error message -
  - 550 Allocation of temporary data set failed: (rc=4, err=970C,
  info=0000)
  This means the allocation of the temporary data set used to hold
  the IEBCOPY unload/load failed because the specified size is too
  large to fit on one DASD volume.
