PK13818: MESSAGE FABZ028E USING DATABASES RANDOMIZED BY DFSHDC10

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DB repair facility appears to have a problem with databases
  randomized by DFSHDC10. I get message FABZ028E: "RBA beyond
  extents (RBA=FFFFFC00). For VSAM, ensure that the RBA entered is
  an even value"
  For a key known to be in the database. I can successfully find
  the segment by RBA, which is what leads me to suspect that the
  problem is something to do with the randomizer.
  If I recreate the database using randomiser DFSHDC40, DB repair
  can find the segment by key.
