DB2 FOR LUW / DB2FORLUW / 970 - DB2

If you have an application that is calling SQLSetEnvAttr() with 
SQL_ATTR_DB2TRC_STARTUP attribute 
and you compiled this application under DB2 9.7 FP8, this same 
application may fail with SQL_INVALID_HANDLE (-2) under 10.1 FP2 
due to the way 
SQL_ATTR_DB2TRC_STARTUP is defined across those versions. 
 
From 10.1 FP2 sqlcli1.h : 
#define SQL_ATTR_DB2TRC_STARTUP_SIZE   3019 
 
 
From 9.7 FP8 sqlcli1.h : 
#define SQL_ATTR_DB2TRC_STARTUP_SIZE   3017 
 
 
Example : 
 
Compile the following program under DB2 9.7 FP8 : 
 
 
#include <sqlcli1.h> 
int main() 
{ 
   SQLRETURN cliRC = SQL_SUCCESS; 
   cliRC = SQLSetEnvAttr(SQL_NULL_HENV, 
SQL_ATTR_DB2TRC_STARTUP_SIZE, 
(SQLPOINTER) 32, SQL_IS_UINTEGER ); 
 
   if (cliRC != 0) 
   { 
      printf(" cliRC = %d\n", cliRC); 
      return cliRC; 
   } 
   else   printf("  OK :  %d\n", cliRC); 
 
 
   return 0; 
} 
 
Execute it under DB2 9.7 FP8 : 
 
$ ./test 
 cliRC = 0 
 
CLI traces show : 
 
SQLSetEnvAttr( hEnv=0:0, 
fAttribute=SQL_ATTR_DB2TRC_STARTUP_SIZE, vParam=32, cbParam=-5 ) 
    ---> Time elapsed - 0 seconds 
 
SQLSetEnvAttr( ) 
    <--- SQL_SUCCESS   Time elapsed - +3.087500E-002 seconds 
 
 
Now, if you run the same application under DB2 10.1 FP2 : 
 
$ ./test 
 cliRC = -2 
 
The CLI traces show : 
 
SQLSetEnvAttr( ) 
    <--- SQL_INVALID_HANDLE   Time elapsed - +3.900000E-005 
seconds

Recompile your application under the DB2 version you wish to 
execute it.

DB2 Version 9.7 Fix Pack 9 for Linux, UNIX, and Windows
 DB2 Version 9.7 Fix Pack 9a for Linux, UNIX, and Windows
 DB2 Version 9.7 Fix Pack 10 for Linux, UNIX, and Windows
 

The problem was first fixed in DB2 9.7 FP9 
 
Now the define will be as #define SQL_ATTR_DB2TRC_STARTUP_SIZE
