IZ98559: WRONG STATISTICS IN TOPAS MAIN PANEL. APPLIES TO AIX 7100-01

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In the topas PAGING area, if the statistics is displayed with
  a K, the K is never cleared, and therefore gives the appearance
  of a very large number when it's really trying to display a
  small number.
  

Local fix

Problem summary

• .
  In the topas PAGING area, if the statistics is displayed with a
  K, the K is never cleared, and therefore gives the appearance
  of a very large number when it's really trying to display a
  small number. Also we are sending a 'long long' or 'double'
  type vaule to a function which can receives only 'long' type
  value, this can cause showing up an undefined statistics
  value.
  

Problem conclusion

  Note here that all the statistics are of type either 'long long
  int' (8 bytes) or 'unsigned long', that means they can't be
  accomodated into a long type variable. But see this:
  .
  topas.h defines:  typedef struct { int             line;
  int             col; void            (*fun) (long, int, int);
  <--- note : - pointer to a funtion that receives a LONG and 2
  int variable, float           mul; } where;
  .
  global.c defines:  where prt1   = { {11, 56, p7, 1.0}, {12, 56,
  p7, 1.0}, {13, 56, p7, 1.0}, {14, 56, p7, 1.0}, {15, 56, p7,
  1.0}, {16, 56, p7, 1.0}, {17, 56, p7, 1.0}, {17, 74, p41,
  10.0}, {18, 74, p41, 10.0}, {16, 74, p6d4k, 1.0}, {10, 74,
  p6d4k, 1.0}, {11, 74, p41, 10.0}, {12, 74, p41, 10.0}, {13, 74,
  p41, 10.0}, {5, 72, p8l, 1.0}, {6, 72, p8l, 1.0}, {7, 72, p8l,
  1.0}, {20, 55, p8l, 1.0}, {21, 55, p8l, 1.0}, {22, 55, p8l,
  1.0}, {23, 55, p8l, 1.0} };
  .
  global.h declares:  ----------------- void p7(long val, int
  line, int row); void p41(long val, int line, int row); void
  p6d4k(long val, int line, int row); void p8l(long val, int
  line, int row);
  .
  Here are we used the ptr1 arrays:
  topas.c:
  prt1 14 .fun(sysData.fsIgets/etime,prt1 14 .line,
  prt1 14 .col); topas.c:
  prt1 15 .fun(sysData.fsNamei/etime,prt1 15 .line,
  prt1 15 .col); topas.c:
  prt1 16 .fun(sysData.fsDirblk/etime,prt1 16 .line,
  prt1 16 .col); topas.c:
  prt1 7 .fun(sysData.pagePerUsed,prt1 7 .line, prt1 7 .col);
  topas.c:
  prt1 8 .fun(sysData.pagePerFree,prt1 8 .line, prt1 8 .col);
  topas.c:
  prt1 9 .fun(sysData.pageSizePerTotal,prt1 9 .line,
  prt1 9 .col); topas.c:
  prt1 10 .fun(sysData.memRealSize,prt1 10 .line, prt1 10 .col);
  topas.c:
  prt1 11 .fun(sysData.memRealPerComp,prt1 11 .line,
  prt1 11 .col); topas.c:
  prt1 12 .fun(sysData.memRealPerNoncomp,prt1 12 .line,
  prt1 12 .col); topas.c:
  prt1 13 .fun(sysData.memRealPerClnt,prt1 13 .line,
  prt1 13 .col); topas.c:
  prt1 0 .fun(sysData.pagexct/etime,prt1 0 .line, prt1 0 .col);
  topas.c:
  prt1 1 .fun(sysData.vMemSteal/etime,prt1 1 .line, prt1 1 .col);
  topas.c:
  prt1 2 .fun(sysData.vMemPgspgin/etime,prt1 2 .line,
  prt1 2 .col); topas.c:
  prt1 3 .fun(sysData.vMemPgspgout/etime,prt1 3 .line,
  prt1 3 .col); topas.c:
  prt1 4 .fun(sysData.vMemPagein/etime,prt1 4 .line,
  prt1 4 .col); topas.c:
  prt1 5 .fun(sysData.vMemPageout/etime,prt1 5 .line,
  prt1 5 .col); topas.c:
  prt1 6 .fun(sysData.vMemSio/etime,prt1 6 .line, prt1 6 .col);
  topas.c:
  prt1 10 .fun(sysData.memRealSize * memhardlim,prt1 10 .line,
  prt1 10 .col); topas.c:
  prt1 17 .fun(sysData.nfsSv2Calls/etime,prt1 17 .line,
  prt1 17 .col); topas.c:
  prt1 18 .fun(sysData.nfsCv2Calls/etime,prt1 18 .line,
  prt1 18 .col); topas.c:
  prt1 19 .fun(sysData.nfsSv3Calls/etime,prt1 19 .line,
  prt1 19 .col); topas.c:
  prt1 20 .fun(sysData.nfsCv3Calls/etime,prt1 20 .line,
  prt1 20 .col);
  .
  topas.c defines the funtions p7 and p7100:
  .
  void p7(long val, int line, int row) { if(val > 99999){
  p7100((longlong_t)val,line, row); return; } move(line, row);
  printw("%7ld", val); }
  .
  void p7100(longlong_t val, int line, int row) { double
  v = val / 1024.0;
  .
  if(v > 9999.0){ p71000(v,line, row); return; } move(line, row);
  printw("%7.1fK", v); }
  .
  So basically we are sending a 'long long' or 'double' type
  value to the p7 function, but it can hold only a long value.
  The fix is changing the first argument type of the funtions p7,
  p41, p6d4k and p8l as to 'long long int'. These funcitons are
  called through the function pointer defined in the sytructure
  name 'where' hence we need to change this structure as well.
  Also to fix 'the K coming after the PAGING area and never
  cleared issue' we should reduce the column by one character to
  accomodate K/M/G/T. This should be done on the funtion p7100.
