PH00772: IMS KEYLEN REQUIREMENT ON PCB WITH PROCSEQD FOR DEDB SIX WITH SUBSEQ FIELDS IS NOT CALCULATED PROPERLY DURING ACBGEN

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The KEYLEN parameter on DB PCB macro defines the length of the
  key feedback area allocated in the PCB.  When ACBGEN (BUILD
  PSB) is run, the KEYLEN specification is checked on each PCB to
  make sure that the longest concatenated key for a hierarchic
  path of sensitive segments can be stored within the key
  feedback area of that length.  When SUBSEQ fields (/CK..) are
  used in DEDB FPSI, ACBGEN is not calculating the correct KEYLEN
  requirement.

  * PROBLEM DESCRIPTION:                                         *
  * For DEDB that is accessed through its Fast Path secondary    *
  * index (PROCSEQD=) which has SUBSEQ= defined in the SRCH      *
  * fields,  ACBGEN does not include the length of SUBSEQ fields *
  * in the pointer key length for the  minimum required KEYLEN=  *
  * checking.  This may cause the key feedback area that is      *
  * obtained not long enough when the longest physical key       *
  * length accessed thru the primary key is shorter than the     *
  * logical key lemgth accessed thru the secondary index key.    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * INSTALL CORRECTIVE SERVICE FOR APAR/PTF                      *
  ****************************************************************
  Additional Symptoms when ACBGEN finds KEYLEN specified is too
  short:
   DFS0919I  PSB --psbname  -- PCB --dedbname-- KEYLEN SPECIFIED
  TOO SMALL.  KEYLEN SHOULD BE --nnnnn BYTES
   DFS0587I  ERROR BUILDING PSB=psbname   - IT WILL BE DELETED
  FROM ACBLIB.    ***************** E R R O R *******************
  

Problem conclusion

• Routine CMPKEYLN in DBFDLB00 and DBF3BB00 have been modified to
  use the pointer key length that includes SUBSEQ fields in its
  calculation to compute the minimum required KEYLEN= for DEDB
  with PROCSEQD= defined.
