PH04419: MAINFRAME PDS MEMBERS DOWNLOADED AS 0 BYTE FILES INSTEAD OF FILES THAT CONTAIN THE CORRECT CONTENTS.

APAR status

• Closed as program error.

Error description

• When using AD Connect for Mainframe 5.0.5.1 and downloading
  mainframe members from a PDS, the files arrive at the AD server
  with correct file/member name but contain 0 bytes instead of
  the content that the corresponding member on z/OS contains.
  

Local fix

• none known.
  

Problem summary

• PDS datasets under Endevor management typically store a
  "footprint" in the user data field of each directory entry.
  The contents of this footprint could include null bytes (hex 0)
  in the field usually used by ISPF stats to record the "records
  updated" count.  The AD agent contains logic to avoid
  processing members for which this record count is zero.
  Instead, it skips the file classification, and only return a
  header with source file type UNDEFINED, which resulted in the
  AD Build client displaying UNDEFINED type members with a size
  of 0 bytes.
  

Problem conclusion

• IBM AD code was changed to add 2 checks:
  -If the user data field in the PDS directory is not 30 bytes
  but some other length, do not perform any check on the "records
  updated" field and process the member under the assumption that
  it is required.
  -If the user data field is 30 bytes (therefore, it appears to
  contain ISPF statistics) - do some additional checks on
  individual fields to ensure they are reasonable values for ISPF
  statistics - eg. date/time fields are in proper packed format.
  If the user data does not appear to be valid ISPF statistics -
  for example - a string of hex 0 - skip the remaining check on
  "records updated" and process the member (as in the first
  check).
  

Temporary fix
