PK20569: MSGFABO0116A, MSGFABO0204A OR ABEND0C9 WHEN THE NUMBER OF INPUT KEYS IS 16 MEGA OR GREATER.

APAR status

• Closed as program error.

Error description

• SRG does not check the allowable upper bound of the number of
  input keys, which is 16 mega (=16,777,216). As a result, when
  the number of input keys is 16 mega or greater, the following
  problems occurs. If the number of input keys in the key file is
  equal to 16 mega, MSGFABO0204A is issued and the job ends with
  RC08. If the number of input keys in the key file is 16 mega
  plus 1, An ABEND0C9 occurs. If the number of input keys in the
  key file is greater than the above, MSGFABO0116A is issued and
  the job ends with RC08. Unpredictable results occur.

  SRG does not check the allowable upper bound of the number of
  input keys, which is 16,777,215. As a result, when the number of
  input keys is 16,777,216 or greater, the following problems
  occur. If the number of input keys in the key file is equal to
  16,777,216, MSGFABO0204A is issued and the job ends with RC08.
  If the number of input keys in the key file is 16,777,217, an
  ABEND0C9 occurs. If the number of input keys is greater than the
  above, MSGFABO0116A is issued and the job ends with RC08.
  

Problem conclusion

• The module FABOCOMP has been modified so that the message
  MSGFABO0211A will be issued and the job will end with a return
  code of 8 ( RC08 ) when the number of input keys in the key
  file is 16,777,216 or greater.

  * Documentation Change *
  ************************
  IMS Sequential Randomizer Generator for OS/390 V1R1 User's Guide
  ( SC27-0926-01 ) should be changed as follows:
  
  Chapter 2. Operating Instructions
   Input
    Database Key File
  
  * The fllowing item is added to the list of characteristics of
  database key file.
  
  - The allowable maximum number of non-duplicate input keys in a
  key file for an HDAM database, a PHDAM partition, or a DEDB area
  is 16,777,215.
  
  Appendix G. Messages and Codes
   SRG messages
  
  * The following new message is added:
  
  FABO0211A NUMBER OF INPUT KEYS IS 16,777,216 OR GREATER
  
  Explanation: The number of input keys in the key file is
  16,777,216 or greater. The allowable upper bound of the number
  of non-duplicate input keys is 16,777,215.
  
  System Action: SRG ends processing with RC=8.
  
  Programmer Response: Reduce the number of keys in the key file
  and rerun the SRG job.
