Cx_Oracle & Oracle's Instant Client

Hello there, first time here :) , im having many issues trying to set up cx_Oracle module on my Ubuntu OS. My question is if the Oracle's Instant Client version it must be the same as my Oracle's Server Version ??

There is no Oracle requirement for the client & database libraries to be exact. For example, Instant Client 11g will connect to 10g databases.
If you have a database on the same machine as Instant Client then you need to be careful about which tools pick up which of the two sets of Oracle libraries. This is a common problem for Windows users.
Also on Windows you do need to match the Oracle libraries to those that whatever tool (e.g. cx_Oracle) was built with.

ORACLE 10 INSTANT CLIENT:The procedure entry point OCILobRead2 could not...

The problem still remain:
I've installed oracle 10g instant client
SQL*Plus: Release 10.2.0.3.0 - Production on Wed Jan 10 12:43:40 20
PHP VERSION: php-5.2.0 for Win32
APACHE VERSION: apache_2.0.59 for WIN32
But I've the same old error when I try to restart Apache:
The procedure entry point OCILobRead2 could not be located in the dinamic link library OCI.dll
Is there anyone who can help me to solve this kind of problem?
Thanks in advance.

The solution is that you need to have Oracle 10g client side libraries
installed (or you have to recompile PHP yourself). The oci8 extension
has some version dependent code and the person who builds Windows PHP
builds it with the latest version of Oracle. I was discussing the
impact of this just this week.
Luckily Oracle Instant Client can be downloaded and used for free from

Unable to install 64-bit Oracle ODBC Instant Client on Windows 2008 R2 machine.

I am trying to upgrade the Oracle ODBC driver from the 32-bit version currently installed (ODBC Instant Client Release 10.1.0.5.0, April 2006) to a newer 64-bit version but have not been successful. I have had success at uninstalling and reinstalling the existing 32-bit version package (release 10.1.0.5.0) however when I've tried to install the 64-bit ODBC Instant Client (Release 12.1, December 2012), I run the odbc_install.exe application inside the package. it appears to run without issue/compliant, but then I do not see the 64-bit Oracle ODBC driver anywhere, either if I go via the traditional Administrator Tools --> ODBC Data Sources or if I go to the c:\windows\syswow64\odbcad32.exe route. Further investigation into the ReadMe file (ODBC_IC_Readme_Win.html) reveals that you need the 3 DLLs oci.dll, oraociei11.dll and orannzsbb11.dll which the package does not come with. Where could I obtain the correct version of these DLLs or else where can I get an installation package which already contains them?
Any help with this is greatly appreciated. Thank you

Windows 7, Oracle DB, Instant Client and VBScript

I'm trying to to connect to a Oracle database via vbs on a Windows 7 machine using the instant client. I get an error [Oracle][ODBC][Ora]Ora-12560: TNS:protocol adapter error Code 80004005. Script still works fine in XP using the Microsoft ODBC for oracle. I've setup the system dsn, and added tns_admin option to the system environmental path. Here's the connection line
psconn.Open "DRIVER={Oracle in instantclient_11_2};SERVERNAME=192.168.50.1:1521/PSPRODDB;User Id=user;Password=pass;"
I've tried 32 bit instant client and the 64 bit and get the same messages with both. Any suggestions?

12560 means you didnt supply a tnsnames alias, and a database was not found in that home.
Try this:
"DRIVER={Oracle in instantclient_11_2};DBQ=192.168.50.1:1521/PSPRODDB;uid=user;pwd=pass;"
Using Oracle ODBC Driver
Hope it helps,

Oracle 11g INSTANT CLIENT for Mac OS 10.8 with SQLLDR and WRAP

To Oracle please upgrade INSTANT Client 11g and/or 12c (future) and include two additional utilities I always use SQLLDR and WRAP. Currently I have to open a Linux VM to wrap and use SQL*Loader. I would prefer to do it all in the terminal window.
Actually I would like to see sqlldr and wrap utilities included with all instant clients (Linux, Windows, Mac OS, etc)

PS: the cause for the behavior is, that there is always a client library in the $ORACLE_HOME directory too. And you have to be careful which one you (genezi) picks...

Oracle 10G instant client..

Hi,
we are upgrading Bw 3.1c to NW04s BI 7. Apart from this we need to upgrade oracle 9i to 10g.As far as oracle 10g client is concerned, Is it mandatory to use the oracle instant client? Otherwise we can still use the old oracle client?
Please let me if anybody has any idea about it.
Thank you in advance.
SS

Hello SS,
From NW04S kernel 7.00 onwards oracle instant client is mandatory.Instant Client is a smaller version of the oracle client software which is being shipped with SAP kernels 700 onwards.The basic philosophy that the version of the client software depends on the version of the SAP kernel.The SAP kernel 700 and upwards are all linked against Oracle 10g. Hence the Oracle 10g client software needs to be installed on all 700 kernel based application servers.
Please refer to snotes: 819829 and 180430.
Thanks

Hi,
I have an application that uses Oracle 11gr2. For the Oracle client installation, I first install InstantClient and then run the setup again, choose Custom, and choose "Oracle Database Utilities" since the InstantClient doesn't have exp/imp with it.
My question is, instead of doing 2 steps for installation, how can I just do it once? What corresponding option(s) do I have to select in Custom mode to install InstantClient? Here's a link to a pic for the complete list of items available: http://i.stack.imgur.com/gUT7g.jpg
Thanks.
"choose?"
"Custom"?
an installation GUI?
That doesn't sound like Instant client.
That sounds like the normal fat client.
What is the name of the file you downloaded?

Oracle 11g Instant Client availability on Windows

We have just installed and tested new features on Oracle 11g Linux and Windows.
We had a problem in the deployment phase, we installed the Oracle Instant Client in Windows connected to Oracle 11g Server with Linux.
The systems seems is not working correctly, when will be the instant client 11g for Windows available?
We have a urgent need to know it.
Thanks a lot.
Stefano

I don't think the instant client is available yet for windows nor linux.
As for the 11g client beta on windows, you can get it via ODAC.

ODBC Error: Could't find Oracle Instant Client in present directory.

I am getting the following error when I try to run odbc_install.exe with the Oracle 10g Instant Client Lite version 2:
Could't find Oracle Instant Client in present directory.
The 10g Instant Client Lite version (including the missing MFC71.DLL and MSVCR71.DLL files) is in the directory. What am I missing here??

Can you detail your configuration? What files are in the directories? Environment variables?

Unix ODBC and Oracle Instant Client

When I dowloaded Oracle 11 Instant client the the zip file does not contain the libsqlora.so.11.1 file. the odbc_update_ini file contains reference to it. I am trying to configure ODBC on HP UX Pa Risc to use the Instant Client. I have downloaded the UnixODBC driver manager from UnixODBC.org. But I can't seem to figure out how to hook up Oracle 11 Instant Client. Everything I have searched for indicates that libsqlora.so.11.1 is required for the driver manager to work. Who develops this, is it Oracle, is it UnixODBC.org? Do I need to use an older version of Oracle Instanct Client?
Thank you in advance for any help.

is it "libsq.." or "libsql.."? Did you check odbc.zip? "libsqora.so.11.1" suppose to be part of odbc.zip. From which location you have downloaded? because in my install location I can see that "libsqora.so.11.1" is part of odbc.zip file and same has been referred by odbc_update_ini file. Download fresh tar(odbc.zip) and recheck!

Oracle instant client 10.2.0.4 to connect to oracle database 9.2

got message ORA-03134 when creating ODBC connection to database version 9.2. However, it was successful to connect to database versions 10g and up. Has anyone successfully connected to Oracle 9.2 by using the 10g instant client?
Isn't Oracle 10g instant client supported to connect to 9i databases?
Thanks.
Edited by: andychow on Jul 28, 2010 4:44 PM

I think this is nothing to do with ODBC, to clarify try to connect with sqlplus to same DB.
However, what is your exact Oracle client version?
Looks like there was a bug in 10g, and I think issue is fixed in patch to 10.1.0.3. Check @ 10g client vs 8i server (ORA-03134): news?

ORA-12514 error: Instant Client 11 connect to remote Oracle 8i

I encountered a problem that I have spent hours fixing that. Here is the problem:
I am trying to connect to a remote Oracle 8i server using Oracle 11 instant client: here is my connection string in PHP:
*$conn = oci_connect('db_user', 'db_pass', "db_ip/db_service");*
db_ip is the ip of the server, such as "12.34.56.78". db_service is the service of server, such as "test".
The error shown is "*ORA-12514:* TNS:listener does not currently know of service requested in connect descriptor"
I could use the same client to connect to another oracle 10g server. The php code is same, only change the db_user or db_pass or db_ip. db_service is not provided.
I dont use tnsnames.ora for either oracle *10g s*erver or oracle 8i server. I just use the simple IP of server. Does this matter?
Server using: Windows Server 2008 R2
PHP: php 5.2.17
Oracle Instant Client: 11_2
Any ideas will be appreciated.
Best, Sam

All of the above has succeeded ok; however whilst trying to create new DSN the intsant client is not listing as an available driver. What's missing please?

The package you downloade is not ODBC Instant Client package
Instant Client Concept came into existence from 10.1 onwards only
What you downloaded are the patched 9208 ODBC Drivers
