OCCI -getString problem

I'm having trouble executing code using the OCCI libraries. I suspect that it's an issue with the version of OCCI that I'm using but can't seem to resolve the problem myself.
On Windows 7, I'm using the OCCI libraries from the Oracle Express 11.2 32 bit install. I'm compiling in Eclipse Luna (for 32 bit) 1a using the CDT plugin. I'm using the compiler from Microsoft Visual Studio 12.0.
I'm using the oraocci.lib. (If I use the oraocci11d.lib, my code crashes just trying to make a database connection.) My current problem is with the oracle::occi::ResultSet::getString method. If I call it once on my ResultSet, it works fine. The second call causes my program to crash.
Here is my code:
std::sqlStr;
sqlStr = "SELECT START, END, BATCH_ID, AGENT_ID FROM AGENTS WHERE ID = :1";
connection code, stmt creation, etc
oracle::occi::ResultSet *rs = stmt->executeQuery();
if (rs->next()
   double start = rs->getDouble(1);
   double end = rs->getDouble(2);
   std::string batch = rs->getString(3);
   std::string agent = rs->getString(4); // CRASH!
Here is the exception that I get when I try to debug:
"Unhandled exception at 0x00D82CB8 in DARTester.exe: 0xC0000005: Access violation reading location 0x0000005."
Any help would be greatly appreciated.

It is my fault. I use Fedore Core 4 and gcc4.0. By default it linking with libstdc++.6.so, but when I linkint direct with libstdc++.5.so it OK.
Thank you for support!

OCCI-getString error

The following is a small console program written with Visual C++
6.0 sp 4.
The program has a crash when it tries to destruct the
string variable fodt in the while loop.
Is this a known bug or is there an error in the code ?

Israel,
Most of these errors do indeed arise from missing/wrong
compilation flags/defines. Check out OCCI samples and
the "make.bat" files in your %ORACLE_HOME%\rdbms\demo directory
for the correct flags, includes, and libraries. Here is an
example,
:occimake
cl -GX -DWIN32COMMON -I. -I%ORACLE_HOME%\oci\include -I. -D_DLL -
D_MT %1.cpp /link /LIBPATH:%ORACLE_HOME%\oci\lib\msvc oci.lib
msvcrt.lib msvcprt.lib oraocci9.lib /nod:libc
Regards,
Geoff
the problem also occurs on VC 6.0 without any service pack.
pay attention that the following expression:
typeid(rs->getString(1)
leads to a compiler internal error (getXXX other than string
works just fine !!!).
this, along with some other testings i've conducted might
indicate that oraocci9.lib has been compiled with stl (or just
string) which differs from the version supplied with msvc.
it also can result from missing/wrong compilation flags/defines.
i'm still working on this.
if anyone finds the answer PLEASE contact me !!!

Israel Kalush

GetString-problem

Hello!
Help, i need somebody...
I'm new in C++, VC and Oracle.
I use OCCI to connect on 10g db. Somehow i configured VC so now i can create .exe. I'm not sure that i can repeat configuration:).
In databes there is table whit only varchar2 fields. The problem is in this part of code:

string c2;
 while(rs->next())
{ counter++;
 for(int i=1; i<=5; i++) {
 c2=rs->getString(i);
 cout <<"row: "<<counter<<" field: "<<i<<" "<<c2<<endl; 
 }
 cout <<"******************"<<endl;
}

Nothing smart. But when getString gets something it fails( An unhandled win32 exception occurred in my.exe [3888] . When i reduce dataset only on fiedls whit "where length(varchar_field)<16" it never throw this exception. If i
Somethimes the program goes whitout any problem.
Please help!!!
I didn't find anything helpful on this forum.

which version of OCCI are you using? Can you try on the latest version (10.2 or 10.1.0.5)?

Occi GetString causing a exception with ntdll.dll oracle 10g and MS 2005

hi,
I am getting an exception with using Visual Studio 2005(VC++8) and occi.h 10g client.
When I run the release version I get an exception in ntdll.dll.
The problem is in the getString(). The field in the oracle table is defined as a varchar2(300).
I am new to oracle occi and need a solution because we cannot migrate to another version of the database.
These are the solutions I have tried:
download patches for MS Visual studio
download patched for oracle 10g client
Check that the charset it correct for std:string
I see that others have had the same problem but no one has a solution. If anyone has a solution please email me because I have searched for days!
Thanks

OCCI ResultSet problems

Hi!
My problem is the same as this thread.
OCCI programming
I call the method getColumnListMetaData and the method returns a STL vector with
Metadata objects and it works fine. My problem is when the vector should be deallocated.
When I run the testprogram a get this error message:
*** glibc detected *** double free or corruption (!prev): 0x08121568 ***
The sample code....
vector<MetaData> md = rs->getColumnListMetaData();
//column names to number mapping
map<string, int> columns;
for (int i = 0; i < md.size(); i++)
 columns[md[ i ].getString(MetaData::ATTR_NAME)] = i;
My versions:
CentOS release 4.2 (Final)
Kernel 2.6.9-34.EL
gcc version 3.4.4
OCCI 10g Release 2 (10.2)

Code:
int test(int argc, char **argv)
 const string userName = ".........";
 const string password = "....";
 const string connectString = "..";
 Environment *env = Environment::createEnvironment();
 Connection *conn = env->createConnection(
 userName, password, connectString);
 Statement *stmt = conn->createStatement(
 "SELECT * FROM TEST_TABLE");
 ResultSet *rs = stmt->executeQuery();
 vector<MetaData> md = rs->getColumnListMetaData();
 //column names to number mapping
 map<string, int> columns;
 for (int i = 0; i < md.size(); i++)
 columns[md[ i ].getString(MetaData::ATTR_NAME)] = i;
cout << "Column name: " << md[0].getString(MetaData::ATTR_NAME) << endl;

OCCI Link Problem

Hi,
I am using Oracle 9.2.0.1.0, Redhat 9, gcc 2.96, glibc 2.3.2-11.9. I continually receive the following link problem:

OCCI link problem with gcc2.96 in Redhat7.2, Oracle9.0.1

When I compiled and linked the occi program occidml.cpp with dynamic shared library, all was OK.
But when occidml run, segmentation fault happened.
I'v read a topic that we can build the program with static library to avoid segmentation fault.
So, I recompiled the program and I used the following command to relink it.
/usr/bin/g++ -L/ora9/lib/ -L/ora9/rdbms/lib/ -o occidml occi
dml.o -lclntst9 -locci9 -ldl -lm
But, a lots of errors happened:

Who can help me ? Is the static library libocci9.a with any problem?

I tried clicking on the link and nothing whatsoever happened. So I tried a control click and selected "Open Link in new window" and a new window opened, followed by the Utilities folder opening. I made a test.html file with the link in it, put it on my startup drive and it worked as expected, and ditto for putting it on a second internal drive. I then put it on my iDisk and navigated to it thru its web site address of
http://homepage.mac.com/francines/testlinks.html
and discovered that the two other "local" operation links (to launch ScriptEditor) both worked, but the open folder link no longer did, except by using control click and choosing either "Open link in new window" or new tab. A new Safari window or tab opens, then the Utilities folder opens.
I then tried the page in Firefox, and it didn't work AT ALL, not even with new window or tab. I then tried Mozilla and Netscape. Same deal. The ancient Internet Explorer opened the Utilities folder inside a new browser window rather than the Finder. This might be a clue as to why the link doesn't work as expected, but unfortunately I don't know what it means.

Hello,
I am trying to compile my C++ code (using OCCI) on Sun Solaris 5.9 (SPARC64PLUS) environment.
We have compiled and tested it on RHEL 5 Linux.
The Oracle (10g R3) database is on RHEL 5 server while OCCI/C++ application would be running on Sun Solaris 5.9 server.
Since we have no Oracle installation on the Sun Solaris 5.9 server, there are no OCCI related libraries on this server and hence we are not able to compile our C++ code on Sun Solaris 5.9
Can someone help me on how/where to download OCCI libraries (compile time as well as run time) for Solaris 5.9 ? I could find only Windows and RHEL versions of OCCI libraries on the Oracle website.
Also, how stable is OCCI on Solaris 5.9 ?
Regards,

OCCI Link problem (Error LNK2019: unresolved external symbol) in VS2012

Hi,
I'm having a hard time with this. I'm trying to implement OCCI within my application. Error I'm getting is:
Error 1 error LNK2019: unresolved external symbol "public: static class oracle::occi::Environment * __cdecl oracle::occi::Environment::createEnvironment(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,enum oracle::occi::Environment::Mode,void *,void * (__cdecl*)(void *,unsigned int),void * (__cdecl*)(void *,void *,unsigned int),void (__cdecl*)(void *,void *))" (?createEnvironment@Environment@occi@oracle@@SAPAV123@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@0W4Mode@123@PAXP6APAX2I@ZP6APAX22I@ZP6AX22@Z@Z) referenced in function "private: bool __thiscall ServerDataLoader::getPreSuffixesFromDB(void)" (?getPreSuffixesFromDB@ServerDataLoader@@AAE_NXZ) P:\code\VizTool\VizPortal\DwgDgnConverter\ServerDataLoader.obj DwgDgnConverter

Yes, it looks like linking problem,...but for me everything seems set-up.
- Included header files (from instantclient-sdk-windows.x64-11.2.0.3.0.zip)
- Included library path from OCCI download (11.2.0.3.0)
- Added oraocci11d.lib in linker
Please, what am I doing wrong?
Millions of thanks for any kind of feedback ;-)

Have you succeeded? I tried vs2012 and it passed compilation, but gave the run-time error of _crtisvalidheappointer. But the same code runs well with vs2010. I think Oracle needs to publish the new patch for vs2012

OCCI - getString() fails in subsequent calls

while (rs->next())
cout << << rs->getString(1) ; //name string
How can I solve it?
Thanks in advance.

Hi,
I once had such problem and I solved after reading following message thread on this same forum. Hope this helps you.
Re: getString in ocidml.cpp fails
Have fun ...

OCCI Compiling problem

I am trying to complie a simple OCCI program with the latest Oracle 10g client(with full installation) and gcc 3.2.2-5 (Oracle says OCCI works with gcc 3.2) on a Red Hat 9 box, I got the following error message:
undefined reference to `oracle::occi::Environment::createEnvironment(oracle::occi::Environment::Mode, void*, void* (*(void*,unsigned), void* (*)(void*, void*, unsigned),void(*)(void*, void*))'
undefined reference to`oracle::occi::Environment::terminateEnvironment(oracle::occi::Environment*)'
Does anyone know how to solve it? This program works fine with VC++ 6.0 and it is OK to complie OCI program on the same Linux box.
Thanks in advance!

Never mind. I got it worked.
The final commmand I used like this (myprogram is the executable file on linux):
g++ -o myprogram -L $ORACLE_HOME/lib -L $ORACLE_HOME/rdbms/lib -locci -lclntsh myprogram.cpp
I got the previous problem by missing "-locci". Right now I get a warning, /u01/app/oracle/product/10.1.0/client_1/lib/libclntsh.so: warning: remap_file_pages is not implemented and will always fail, although it does not affect my programm. Anyone know what does it mean?

OCCI setVector() Problem

Hi
 I have written the following OCCI code to call two procedures
1. add1_detail(val in number) which is acceptiing an number as input
2. add_detail2(val in my_type) where my_type is a user defined type (a TABLE of NUMBER type)
I am trying to call both the procedures from the same OCCI program (one at a time). The code is as follows
1 #include <iostream>
2 #include <vector>
3 #include <occi.h>
4 using namespace oracle::occi;
5 using namespace std;
6 int main()
7 {
8 Environment *env = Environment ::createEnvironment();
9 cout << "Connecting to the database" << endl;
10 Connection *conn = env->createConnection( "sanju", "sanju","10.116.64.146:1521/ORCL" );
11 cout << "Environment and Connection created" << endl;
12 //Statement *stmt = conn->createStatement("begin add1_detail(:1);end;");
13 //stmt->setInt (1, 8000);
14 //stmt->executeUpdate();
15 OCCI_STD_NAMESPACE::vector<int> v1;
16 v1.push_back(11);
17 v1.push_back(22);
18 v1.push_back(33);
19 v1.push_back(44);
20 OCCI_STD_NAMESPACE::string schemaName="sanju";
21 OCCI_STD_NAMESPACE::string typeName="my_type";
22 Statement *stmt = conn->createStatement("begin add_detail2(:1);end;");
23 setVector(stmt, 1, v1, "my_type");
24 stmt->executeUpdate();
25 conn->terminateStatement(stmt);
26 env->terminateConnection(conn);
27 Environment::terminateEnvironment(env);
28 cout << "Environment and Connection terminated" << endl;
29 return 0;
30 }
The problem is like this, When I am calling add1_detail() by enabiling lines 12, 13, 14, the program works fine. But when
I try to call the second procedure by enabiling line 15 to 24 and sisabeling 12, 13, 14, the program is showing exception from line no 8 (ie Environment *env = Environment ::createEnvironment();)
Strange!
By using debug mode I came to know that the error is commong from file _ctype.c from the line number 6 below
1 int (__cdecl isupper) (
2 int c
3 )
4 {
5 #ifdef _MT
6 pthreadlocinfo ptloci = _getptd()->ptlocinfo;
7
8 if ( ptloci != __ptlocinfo )
9 ptloci = __updatetlocinfo();
10
11 return __isupper_mt(ptloci, c);
12 #else /* _MT */
13 return isupper(c);
14 #endif /* _MT */
15 }
can any one please help on this matter

Occi conneciton problem in solaris

Hai all,
Any body pls solve my problem
My sytems details are :
OS : SunOS mars 5.10 Generic_118833-33 sun4v sparc SUNW,Sun-Fire-T200
SYSTEM : sparc 64-bit
gcc version : 3.4.6
Oracle 10g :10.2.0
When i am compiling i am getting as :
g++ db.cpp -I /u01/app/oracle/oracle/product/10.2.0/db_1/rdbms/public/ -L. -libocci10 -lclntsh
ld: fatal: library -libocci10: not found
ld: fatal: file /u01/app/oracle/oracle/product/10.2.0/db_1//lib/libclntsh.so: wrong ELF class: ELFCLASS64
Please sugget

In SOLARIS - Sun Studio (CC/C Compiler) the 64 bit flag is -xarch=native64
The above flag if used will compile all your programs in 64bit mode and if not used then all will be in 32bit mode. In g++ compiler , you have to use the similar flag.
The problem is that one of the external libraries you are linking is already 64bit.

OCCI, VS2010 problem

Hi everyone,
well after a lot of trouble i still get the following error message: "The procedure jump point "OCILobGetOptions" was not found at DLL "oci.dll" "

 Employees *pEmployees= new Employees();
 pEmployees->List();
 delete pEmployees;
 cout << "Enter um fortzufahren...";
 cin.get();
 return 0;
Employees::Employees()
 user = "Test";
 passwd = "xxxx";
 db = "Server1:1521/Ora10";
 env = Environment::createEnvironment(Environment::DEFAULT);
 try
 con = env->createConnection(user, passwd, db);
 }catch (SQLException& ex){
 cout << ex.getMessage();
 exit(EXIT_FAILURE);
Employees::~Employees()
 env->terminateConnection(con);
 Environment::terminateEnvironment(env);
void Employees::List()
 Statement *stmt = NULL;
 ResultSet *rs = NULL;
 string sql = "SELECT * FROM INFO";
 try
 stmt = con->createStatement(sql);
 }catch( SQLException& ex){
 cout << ex.getMessage();
 if (stmt)
 try
 stmt->setPrefetchRowCount(32);
 rs = stmt->executeQuery();
 }catch( SQLException& ex){
 cout << ex.getMessage();
 if(rs)
 cout << "Ausgabe:" <<endl;
 while (rs->next()){
 cout << rs->getInt(1) << endl;
 cout << endl;
 stmt->closeResultSet(rs);
}well i will try somethink tomorrow and hope that it will work :D

OCCI linking problems on Solaris

Hi All,
I'm writing my first occi application on Solaris and am having trouble linking to the Oracle libraries. Below is the code; I'm using Solaris 2.8, gcc 2.95.3.
----------------- test.cpp -----------------------------
include "occi.h"
#include <stdio.h>
using namespace oracle::occi;
int main()
Environment *env;

conn = env->createConnection("SCOTT", "TIGER", "");
catch(SQLException &e)
// handle exception
return 0;

I tried also linking libocci.so, but resulted in even more tedious errors.
Any suggestions would be greatly appreciated. Thanks!!

Do you have any other suggestions? Though Linux sounds good, I have no choice but to develop on Solaris.
