Compile pro*c file with "-DDAEMON -DBACKGROUND" option on Solaris [message #345500]

Hello:

I am using Solaris 10, Oracle 10g, and Sun One Studio compiler version 8.

I have 2 Pro*C program (ABC.pc and XYZ.pc), both use the following command for DB connections.

=== Start of Code (Common) ===

printf("Start");

exec sql connect / at DBNAME ;

if (sqlca.sqlcode != 0)
{
printf("Fail");
return -1;
}

printf("Success");

=== End of Code (Common) ===

Both program work fine in Oracle 9i and Solaris 8
However, after upgrade to Oracle 10g and Solaris 10
ABC cannot print out anything and directly jump back to parent function.
While XYZ success fully connect to database and perform PL/SQL.

Here is the cpp compiler files:

=== Start of Compile file (ABC) ===
ORACLE_HOME=/oracle/product/10.2
ORACLIB=$ORACLE_HOME/lib32
PROCLIB=$ORACLE_HOME/precomp/lib

ABCLIB = <ABC daemon library path>
/opt/SUNWspro/prod/bin/CC ABC.cpp -library=iostream -library=rwtools7 -o $ABCLIB/ABCdaemon -I$PROCINCLUDE -I$SRC -L$ORACLE_HOME/lib32 -R/$ORACLE_HOME/lib32 -DDAEMON -DBACKGROUND
=== End of Compile file (ABC) ===

=== Start of Compile file (XYZ) ===
ORACLE_HOME=/oracle/product/10.2
ORACLIB=$ORACLE_HOME/lib32
PROCLIB=$ORACLE_HOME/precomp/lib

XYZLIB = <XYZ library path>
XYZSRC = <XYZ source path>

CPPLIB=/opt/SUNWspro/prod/include/CC/rw7/rw
/opt/SUNWspro/prod/bin/CC XYZ.cpp -library=iostream -library=rwtools7 -o $XYZLIB/XYZ -I$XYZSRC/XYZ -I$PROCINCLUDE -I$CPPLIB -L$ORACLE_HOME/lib32 -R/$ORACLE_HOME/lib32
=== End of Compile file (XYZ) ===

The difference is "-DDAEMON -DBACKGROUND" in the compilation file.
Also ABC is a child process while XYZ is master process.
Is there any idea for this?

Thanks ahead for any assistance.

Here is some update, it turns out that is not related to the -DDAEMON -DBACKGROUND option, and is still unable to connect to Oracle.

source
==========================
#include "genConst.h"
#include "genInclude.h"

EXEC SQL INCLUDE SQLCA;

int main (int argc, char* argv[])
{
exec sql begin declare section;
char luid20;
char dbname20;
int lnCnt = 0;
exec sql end declare section;

printf("Testmain.cpp : main() Testing 1 \n");

strcpy(luid, "/");
strcpy(dbname, "TESTDB");

printf("Testmain.cpp : main() Testing 2 \n");

exec sql connect :luid at :dbname;

printf("Testmain.cpp : main() Testing 3 \n");

EXEC SQL
EXECUTE
BEGIN
select count(*)
into :lnCnt
from testtable;
END;
END-EXEC;

printf("Testmain.cpp : main() Testing 4 \n");
if (sqlca.sqlcode != 0)
{
printf("Testmain.cpp : main() Testing 5 %i \n", lnCnt);
printf("%.*s \n",sqlca.sqlerrm.sqlerrml,sqlca.sqlerrm.sqlerrmc);
return -1;
}
else
{
printf("Testmain.cpp : main() Testing 6 %i \n", lnCnt);
}

printf("Testmain.cpp : main() Testing 7 \n");
return 0;
}

compilation command
==========================================================
$ORACLE_HOME/bin/proc $TEST_HOME/Testmain CODE=CPP CPP_SUFFIX=cpp SQLCHECK=SEMANTICS SYS_INCLUDE=test INCLUDE=/usr/include USERID=test/test@$ORASID
/opt/SUNWspro/prod/bin/CC Testmain.cpp -library=iostream -library=rwtools7 -o $TESTLIB/test -I$TESTSRC/test -I$PROCINCLUDE -I$CPPLIB -L$ORACLE_HOME/lib32 -lnsl -lclntsh -R/$ORACLE_HOME/lib32

Output
===============================
Testmain.cpp : main() Testing 1
Testmain.cpp : main() Testing 2
Testmain.cpp : main() Testing 3
Testmain.cpp : main() Testing 4
Testmain.cpp : main() Testing 5 0
ORA-01012: not logged on

So, anyone has any idea how to resolve this error? So that "ORA-01012"
does not show up?
