PK43833: FPA ANALYZE COMMAND REPORT DATA TRUNCATED

APAR status

• Closed as program error.

Error description

• 1. ABEND0CB when processing the ANALYZE command.
  2. When actual data values of some fields of the ANALYZE
     command reports are larger than the Max possible number to
     report, the first part of the number will be truncated due to
     an overflow condition. Such field must be shown by C'***' to
     indicate an overflow condition.
  This is a logical forward fit of HPFPU V2R2 FPB APAR PK42116 and
  PK43375.

  Forward Fit APAR of FPB V2R2 PK42116 and PK43375:
  This APAR solves the following 2 problems.
  1.IMS High Performance Fast Path Advanced Tool Analyze function
  failed with an abend S0CB (decimal divide exception) on the DP
  instruction in Analysis report function.
  The abend happened during calculating the average of IOVF CI's
  used in the IOVF section of the DEDB Area Analysis report for
  Freespace Analysis.
  2.When actual data values of some fields of the DEDB Area
  Analysis reports are larger than the Max possible number to
  report, the first part of the number will be truncated due to
  an overflow condition. The field should indicate C'***' to show
  the overflow condition.
  

Problem conclusion

• 1.The cause of the abend was the overflow condition which had
  happened when a large number of IOVF CI (29,980) was divided by
  a small number of UOW (1).
  The divide has been held using 8 bytes work field which is
  divided by 5 bytes field. In this case the heading 3 bytes are
  used for the quotient.
  Internally 29980 is used as 299800 (4 bytes decimal), so that
  the overflow condition happened on 3 bytes quotient field as a
  result of divide.
  As the maximum number of UOW is 32767, 3 bytes length field is
  enough for the value of UOW. The UOW field has been changed
  from 5 bytes to 3 bytes in this APAR to avoid the overflow
  condition. The quotient field has changed from 3 bytes to 5
  bytes by this modification.
  
  2.The steps which check if the data value is larger than the Max
  possible number to report have been added for some field in this
  APAR.
  The data value which is larger than the Max possible number to
  report will be indicated with C'***' in FPA Analysis reports.
  The modified fields are following.
  
   - DOVF AVG in FREESPACE ANALYSIS
   - DOVF S/D in FREESPACE ANALYSIS
   - DOVF MAX in FREESPACE ANALYSIS
   - DOVF MIN in FREESPACE ANALYSIS
   - IOVF AVG in FREESPACE ANALYSIS
   - IOVF S/D in FREESPACE ANALYSIS
   - IOVF MAX in FREESPACE ANALYSIS
   - IOVF MIN in FREESPACE ANALYSIS
   - SDEV of ACTUAL LENGTH in DB RECORD PROFILE ANALYSIS
   - MAX of DOVF ONLY in DB RECORD PLACEMENT ANALYSIS
   - MIN of DOVF ONLY in DB RECORD PLACEMENT ANALYSIS
   - MAX of IOVF ONLY in DB RECORD PLACEMENT ANALYSIS
   - MIN of IOVF ONLY in DB RECORD PLACEMENT ANALYSIS
  
  HFPA5MDA has been modified to change UOW field length from 5
  bytes to 3 bytes.
  HFPA5FD0 and HFPA5FI0 have been modified to proceed the 5 bytes
  length quotient field and also have been modified to indicate
  with C'***' that the overflow condition occurred on corresponded
  fields.
  HFPA5PF0 and HFPA5RP0 have been modified to indicate with C'***'
  that the overflow condition occurred on corresponded fields.
  Modules below have been reassembled.
