RE: ILEC and QWCRSSTS

Steve, 

Thanks for the source code, without it I would have never picked up on the
culprit in this particular problem.

Looks like problem is with "reset statistics" literal passed to QWCRSSTS
being 4 bytes in length when it should be 10 bytes long padded with blanks.
I have recreated your UDF on my V5R1 box and it runs just fine.
Here is slightly modified code.

#include <stdio.h>

#include <string.h>

#include <qwcrssts.h>

 

void CPU(

  char*  out,

  short* outind,

  char* sqlstate,

  char* funcname,

  char* specname,

  char* msgtext )

{

  Qwc_SSTS0200_t info;

  double cpupct;

 

  QWCRSSTS(&info, sizeof(info), "SSTS0200", "*NO       ",
"\0\0\0\0\0\0\0\0");
 

  cpupct = info.Pct_Processing_Unit_Used / 10;

  sprintf(out, "CPU PCT = %2.1f", cpupct);

  *outind = 0;
}             

CREATE FUNCTION elvis/CPU()    
RETURNS varCHAR(50)

Here is the code and exactly what I did:

/*
This method will be called from DB2

*/
#include <stdio.h>
#include <string.h>
#include <qwcrssts.h>
#include <qusec.h>

void CPU(
char* returnMessage,
short* inind,
short* outind,
char* sqlstate,
char* funcname,
char* specname,
char* msgtext )
{
Qwc_SSTS0200_t info;
Qus_EC_t errcode;
double cpupct;

memset(&errcode, 0, sizeof(errcode) );

QWCRSSTS(&info, sizeof(info), "SSTS0200", "*NO ", &errcode);

cpupct = info.Pct_Processing_Unit_Used / 10;
sprintf(returnMessage, "CPU PCT = %2.1f", cpupct);

*outind = 0;
}

select cpu() from sysibm/sysdummy1

Query cannot be run. See lower level messages.

If there is more information I need to provide, can you instruct me on how
to get that information ?
