How did you install Oracle? Did you installed the server version? You should download and install a upgraded version of occi library before using it on your system.
http://www.oracle.com/technology/tech/oci/occi/occidownloads.html
And the library can be used on your system. Yours is rh as5, right?i do not agree.As he is using linux,OEL 5.4.probably the OCCI is already installed.

What is the diffrence between OCI and OCCI?

What is the diffrence between OCI and OCCI?

Will Lee wrote:
What is the diffrence between OCI and OCCI?Beside the other answers, there are a few additional points to consider:
1) OCI is the "gold" standard API. New stuff is always available in OCI first, and only later trickles down to other APIs, like OCCI.
2) OCI is a low-level API, harder to get started with, than OCCI. APIs in OCI are often "untyped", taking a void*, which opens the door for errors.
3) In OCCI you set values, while in OCI you bind them. So OCCI takes a copy of your values, while OCI takes an address at which to later read the value. This opens the door to subtle bugs where you pass the address of a temporary in OCI, which later crashes in some mysterious ways. So OCCI is way safer in this regard.
4) OCI is C code, which is very portable. Because OCCI is C++ code, and on Windows you can't easily mix and match libraries compiled with different versions of Visual C++ (VC6, 7, 8, 9), you have to wait for Oracle to make a new build with the latest MS compiler. Just see the number of questions on this OCI forum and the OCCI one.
5) OCI is used internally by Oracle to write many of their own tools, it's the lingua franca between the Core DB group and the other groups. Since they use it themselves, it's much more stable that OCCI, which is mostly only used by outside customers.
6) The way SQL objects are dealt with in OCI and OCCI is fundamentally different, to the point where you can't mix and match OCCI and OCI object calls.
#1 above is one reason we had to abandon using OCCI, lacked support for the new in 11g BinaryXML, but that's just one example.
IMHO OCI is the way to go, if you want the latest and greatest. Yes, it's more difficult to code against, so the learning curve is steeper, but once you've reached critical mass it's just fine. If you write code in C++ as opposed to C, you can easily make it a lot safer with a thin C++ layer on top which, unlike OCCI, still allows you access any OCI raw handle to do stuff the wrappers don't expose.

Reason to explain these performances of odbc and occi...

I wrote some simple test programs to compare the performances of odbc and occi accessing Oracle.
These programs were wrote in C++. The occi and odbc were given under almost the same circumstance.
The result is: when executing query(simple select) the odbc is fast than occi. When executing insert sentences, the occi is much more fast than odbc does.
My computer environment: Oracle 10g, Oracle instant cilent, VS 8.0.
Do they all access oracle through OCI interface? How to explain the result?
Someone give me some hints , please.

Hi,
With the limited info available, I can't offer any specific suggestions that will help here.
Usually sqlnet tracing is a good thing to check to see if maybe it's round trips causing the discrepency, packet/buffer sizes, query differnces, etc.
Server side sql tracing is often useful as well to check bind types, query execution, etc.
Yes, both Oracle's ODBC driver and OCCI are written in OCI, but they have completely different implmentations: array fetching, statement caching, buffer sizes, etc. Simply because they're both written in OCI doesnt mean they share an implmentation.
Hope it helps,
Greg

AQ and OCCI

Hi!
Env: Oracle 9.2, Linux Mandrake 8.2/Suse 8.1
Is there a way to get OCCI work with AQ? There are no AQ classes that we can find and mixing OCCI and OCI (for AQ functions) results in SEGFAULTs in OCIAQEnq and OCIAQDeq (although, a message is enqueued before OCIAQEnq SEGFAULTs)
TIA

If you are using Object payloads, it wont work as OCCI processes Objects differently from OCI.

OCCI working in VS6.0 and giving error in VS2005 - Please help

I am trying to recompile one of the OCCI program I have created in VS6.0, in VS2005. I am ending up with errors.
During

lot of DLLs (oranro10.dll, orantcp10.dll,oranhost10.dll, ORANCDS10.DLL, orantns10.dll, ORAPLS10.DLL,ORASLAX10.DLL, ORAPLP10.DLL, orahasgen10.dll etc...) are saying Cannot find or open a required DBG file.
During

Unhandled exception at 0x612f89e9 in occitrail.exe: 0xC0000005: Access violation reading location 0xcccccccc.
Whether any body has idea why this error is happending and What I have to do for not to get this error.
Thanks in advance for your help,
Chandra.

Hello,
to be on the safe side I advise to do :
- install Oracle 10.2.0.3.0 Instant Client (not sure whether version 10.1. is causing the problem with your OCCI software)
- install the OCCI 10.2.0.3.0 Patch 13
- clean & rebuild your application linking the oraocci10.lib or oraocci10d.lib (debug version) provided with the patch
The problem of your application could be caused by different runtime versions of the microsoft mfc/crt runtime libraries used by your main program and occi dll. - Welcome to DLL/Manifest hell ;-)
You can have a look at the manifest file you got with the OCCI patch, there you see which runtime DLLs OCCI is expecting.
You can check which Microsoft runtime DLLs are loaded using the software 'dependency walker'. Just make sure ONLY one version of the runtime will be loaded (e.g. mfc80.dll, msvc80.dll ... VC80 versions are used with VS2005).
Check if your application is loading the new, patched OCCI DLL (oraocci10.dll) not some old ones....

Good luck

OCCI for Oracle 9i and MS Visual Studio 2005

Hello.
Where do I get OCCI *.lib and *.dll files for Oracle 9i and MS Visual Studio 2005 (VC 8)?
Roman Perepelitsa.

I was able to use MS Visual Studio 2005 and OCCi classes. There is a catch though, I was not able to use the debug library dll as it will crash. So I was not able to debug any code using the VS debugger, instead, I use the old and lengthy process: insert printf statements.

OCCI and non-blocking

I'd like to use the OCCI interface in a non-blocking mode. Does anyone have any experience with this? Looks like I need to use a combo of OCI and OCCI calls to set the OCI_HTYPE_SERVER handle with the OCI_ATTR_NONBLOCKING MODE. However, my stmt->executeQuery() method seems to be throwing an exceptions, which I would have though would have been the OCI_STILL_EXECUTING error, but it's not. The exeception is an "ORA-32103 error from OCI call". If I continue to do another stmt->executeQuery(), I eventually get an access exception.
Anyone have any code snippets using OCCI in non-blocking mode?

I use threads. ACE/TAO to be precise.
I have singleton class that manages the Oracle environment and connection as well as being a statement
factory.
Just have a thread perform your stmt->executeXXX() method and you will not need to worry about non-blocking.
That's how I do it and it works well.

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
Sheryl

OCCI and ms vc++ (again)

It would appear that a reccurent theme is compilation and linking problems with msvc6 and occi.
I have resolved all those issues, but a slight one remains.
I copy'n'pasted the 'OCCI in 8 lines only!' from oracle.com added the headers and the 'using namespace ...' and it compiled fine.
But on env->createConnection I get a
First-chance exception in occitestcon.exe (KERNEL32.DLL): 0xE06D7363: Microsoft C++ Exception.
I have tried linking using both oraocci10.lib and oraocci10d.lib.
Suggestions are most welcome.

In the 10gR1 release on Windows, 3 compiler specific versions of the OCCI libraries are installed :-
VC6 : oraocci10.lib under %ORACLE_HOME%\oci\lib\msvc & %ORACLE_HOME%\oci\lib\msvc\vc6. oraocci10.dll under %ORACLE_HOME%\bin & %ORACLE_HOME%\oci\lib\msvc\vc6
VC7 : oraocci10.lib under %ORACLE_HOME\oci\lib\msvc\vc7. oraocci10.dll under %ORACLE_HOME\oci\lib\msvc\vc7.
VC71 : oraocci10.lib under %ORACLE_HOME\oci\lib\msvc\vc71. oraocci10.dll under %ORACLE_HOME\oci\lib\msvc\vc71.
Please ensure that you link with the appropriate oraocci10.lib and have the corresponding oraocci10.dll first in the PATH. Typically, %ORACLE_HOME%\bin will be first in the PATH.
The 'd' versions (oraocci10d.lib/oraocci10d.dll) should be used if the debug version of the MSVC C-Runtime is going to be used (/MDd compiler flag).

OCCI 10.2.0.3.0 Patch 13 cause crash ntdll.dll on vista 32bit

hi,
I ceated an application using VC++ 2005 and OCCI 10.2.0.3.0 (update patch 13). the application run smoothly on 2000/XP. But if it is run on vista (32bit, tested on several computer), it ocassionally creates crash (not always) when trying to connect to oracle server (also when trying to connect to non existance server, sometimes crash and sometimes successfully displaying time out message),
The crash message is as follows:
Problem Event Name:     APPCRASH
Application Name:     myapp.exe
Application Version:     0.0.0.0

here's the code snippet:

     Connection* m_occiCon;
     m_occiEnv = Environment::createEnvironment();
     if (m_occiEnv != NULL)
          m_occiCon = m_occiEnv->createConnection(user, pass, constr);
          if (m_occiCon != NULL) return SUCCESS;
catch (SQLException ea)
     m_strLastErr = _T(ea.what());
     return FAILED;
I then tried to upgrade the OCCI using OCCI 11.1.0.7.0 (using the same source code). It also creates random crash but on OraOCIEI11.dll (not ntdll.dll) as follows:

hi again,
I tried to change the createEnvironment into the following:
m_occiEnv = Environment::createEnvironment(Environment::THREADED_MUTEXED);
and somehow, using the latest OCCI 11.1.0.7.0 with the above code, the application seems running well. Tested around 40 times, haven't got any crashed.
When using the OCCI 10.2.0.30 patch 13 with the above code, the application occasionally is still crashed.

Which version of OCCI for Oracle XE 10.2?

Hi,
I have Oracle XE, Linux version 10.2.0.1 installed. I want to connect my C++ application running on the same machine as the database.
I've seen lots of dire warnings about the importance of making sure that the right versions are installed, but after trawling through the (frankly confusing) documentation I can't for the life of me work out which version of the OCCI I'm supposed to use to connect to this version of the database. Can somebody please tell me?
Also, as I want to run this application on the same machine as the database, can I use some of the libraries that are installed with Oracle 10g, rather than having to install them separately?
Thanks,
L.

Hi,
The key parts where the version is truly important when using OCCI are:
- the compiler (and runtime libraries)
- the OCCI libraries
- the Oracle Client version
Under Linux the OCCI version 10.2 libraries are compatible with gcc (g++) 3.4.3 through 4.1.x versions so you should be OK with that part.
When using Express Edition on Linux and having everything on the same machine you automatically have a "match" between the Oracle Client and OCCI libraries (since they are all under the one and only Oracle Home).
On my Express Edition test machine I have the following version of gcc and I have not had any issues (so far!) with OCCI and the database installed "as is":
[oracle@oel02 ~]$ g++ --version
g++ (GCC) 3.4.6 20060404 (Red Hat 3.4.6-3.1)

Correct OCCI connection String

Hi,
I trying to write some small application on a 32bit Centos machine, with g++ and OCCI, I have correctly setup the library linking and have some sample code running alright, however I don't seem to be able to get a correct connection string to connect to a remote 11g database (11.0.2.3).
below are codes that I have tried.
[code]
#include <occi.h>
#include <iostream>
using namespace std;
using namespace oracle::occi;
int main(){
        string userName = "user";
        string password = "STRONGPW";
        string connectString = "";
        try{
                Environment *env = Environment::createEnvironment();
                        cout << "before create connection\n";
                        Connection *conn = env->createConnection(userName, password, connectString);
                Environment::terminateEnvironment(env);
        }catch(exception& e){
                cout << e.what();
[/code]
I have double confirmed the username and password, and whenever it goes the createConnection method, it will throw exception error,
I am compiling and running as root, I have tried all sort of connection strings
connectionString = "";
ORA-12546: TNS:permission denied
connectString = "TCP://192.168.1.2:1522"; // I did also try "tcp://192.168.1.2:1522"
ORA-12154: TNS:could not resolve the connect identifier specified     (192.168.1.2 being host machine, 1522 being listening port)
connectString = "User Id=user;Password=STRONGPW;Data Source=ORCL222";
ORA-12154: TNS:could not resolve the connect identifier specified    (ORCL222 being name specified in $ORACLE_HOME/network/admin/tnsnames.ora)
connectString = "DataSource=" // I did try "ORCL222="
" (DESCRIPTION ="
"       (ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1522))"
"    (CONNECT_DATA="
"      (SERVICE_NAME = ORCL2)"
"      (SERVER = DEDICATED)"
ORA-12154: TNS:could not resolve the connect identifier specified    (ORCL2 being ORACLE service name)
did I miss anything? or is there any spacing in the connection string that I might have did wrongly?

Hi Darryl,
Thanks for trying to answer, I found the answer in
Oracle® C++ Call Interface Programmer's Guide 10g Release 1 (10.1)
the correct connection string seems to be
192.168.1.2:1522/ORCL2 for my case

Hi Christina,
This is what I did using Visual Studio 2008 Professional Edition on Windows Server 2008 64-Bit:
I downloaded the Instant Client Basic and Instant Client Package - SDK for Windows (x64) from here:
http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winx64soft.html
I then downloaded the OCCI for Visual C++9 (VS 2008)[Windows x64] from here:
http://www.oracle.com/technology/tech/oci/occi/occidownloads.html
I think these are the same downloads you used.
1. I then extracted the Instant Client packages to C:\Temp which created the following directory:
C:\Temp\instantclient_11_1
2. The Instant Client SDK was extracted to C:\Temp as well into the following directory:
C:\Temp\instantclient_11_1\sdk
3. I extracted the OCCI package and then moved the libraries, dll files, and manifest files into C:\Temp\instantclient_11_1\sdk\lib\msvc\vc9
4. I copied oraocci11.dll and oraocci11d.dll from C:\Temp\instantclient_11_1\sdk\lib\msvc\vc9 to C:\Temp\instantclient_11_1
5. I removed oraocci11.lib from C:\Temp\instantclient_11_1\sdk\lib\msvc
6. I added C:\Temp\instantclient_11_1 to the system path
7. In Visual Studio 2008 I added the include and library paths as follows:
Tools -> Options... -> Projects and Solutions -> VC++ Directories
Platform: x64
Show directories for:
Include files -- here I added C:\Temp\instantclient_11_1\sdk\include (I removed all other Oracle include directories for the test)
Library files -- here I added C:\Temp\instantclient_11_1\sdk\lib\msvc and C:\Temp\instantclient_11_1\sdk\lib\msvc\vc9 (I removed all other Oracle library directories for the test)
8. Added oraocci11.lib to the linker in Project -> OCCITest Properties... -> Configuration Properties -> Linker -> Input -> Additional Dependencies -> oraocci11.lib
9. I then built and executed the simple test you linked to above with no errors.
Here's the build log for the release build:

OCCI with gcc 3.2

Has anybody had luck with OCCI with gcc 3.2? I am having problems linking the libraries and it seems that OCCI does not support gcc3.2. Does anyone know what version of gcc is supported for Oracle 9.2 ,as I couldn't find any information about support version in documentation.

Definitely use gcc 2.95.3.
I was using Red Hat 8.0 that ships with gcc 3.2.x.
The moment I installed 2.95.3 everything worked fine. Compiled OCI and OCCI demos first time.
Have since created C++ program that talks with OCCI library.
