Loading oci.dll Error

Trying to connect to Oracle for the first time using Visual Studio.Net. I have created a App that has a connection to an Oracle database. That was easy. I then tried to populate a datareader and started receiving the error " Unable to load dll ("oci.dll"). I browsed for .dll and did not find it. My question is how to I get this .dll on a developement (WinXP) workstation and also on a production server running IIS 5.0 to connect to an oracle database? I am new but this is turning out to be a challenge. Thanks for the help in advance!!

John,
If you have a proper installation of Oracle Server or Client, oci.dll should be in your %Oracle_Home%\bin directory. For example, c:\Oracle\ora92\bin.

Toad Error - Cannot load OCI DLL: C:\Oracle\instantclient_11_1\oci.dll

Hello All,
Help needed to fix this error.
We are getting the below error from Toad after fresh install on Windows 7 64 Bit.
Toad for Oracle Base
Version: 10.6.1.3
Cannot load OCI DLL: C:\Oracle\instantclient_11_1\oci.dll
We are using the Oracle Instant Client (instantclient-basic-nt-11.2.0.2.0).
We are able to connect to the database from the command line successfully, but when we tried to launch the Toad and connect it we are getting the above error.
How do we fix this issue?
Thanks in advance.

So is this a Toad issue or an Oracle client issue?More like a general software or programming "issue". If Toad (or other program) is 32-bit, then loaded libraries (e.g. Oracle Client dll's) needs to be 32-bit.
I'm sure this is documented in requirements for Toad. See e.g. [url http://toadfororacle.com/servlet/KbServlet/download/4264-102-12585/10.6_ReleaseNotes.htm#SystemRequirements]Toad 10.6 Release notes.

Cannot Load OCI.Dll

Hello:
I just installed the 64-bit version of 11g Release 1 (11.1.0.6) on a server that is running 64-bit Windows 2003 Server.
The installation was successful and I checked using SQL Plus. I am able to log and execute queries. I am also able connect using SQL Developer.
However, when I tried to use SQL Navigator (version 6.1) or Toad 10.0, I get an error message "... Cannot load OCI.DLL".
When I tried to install another COTS product, it complains that it was unable to find Oracle Client and/or Oracle OLE Objects.
I was trying both the tasks on the server itself.
Any ideas on how I can resolve the issues?

I have the same problem: Oracle 11 R2 on Solaris x86-64 and Oracle client (11.1.0.7.0 x64, unfortunately, there's no client higher than that version.). After installing TOAD 10.1 i've checked client connection:
SOFTWARE\WOW6432NODE\ORACLE (Oracle Root)
ORACLE_HOME_NAME:
ORACLE_HOME: C:\app\User\oracle
ORACLE_SID:
NLS_LANG:
SQLPATH:
LOCAL:
C:\app\User\oracle\Bin exists.
C:\app\User\oracle\Bin is in PATH.
Client DLL: C:\app\User\oracle\Bin\oci.dll
Client Version: 11.1.0.7.0
Home is valid.
So, TOAD can see the client, but when i'm trying to connect it i got an error:
Cannot load OCI DLL: oci.dll
Any suggestions?

Help!my application can not load oci.dll

i have a server with windows 2003 enterprise sp2, oracle 10g was installed on it.now i want to run a .net application,but it's not working,cause oci.dll can not be loaded. then i installed PL/SQL and instant client 11g. but still not working. the error is :"initialization is error, can not load oci.dll.....returned 0". also,i wroted a small application to load oci with win32 api(LoadLibrary) and returned 0 too.
I'm sure there are no 32bit,64bit things. from os to application,32bit was checked. and i changed server but same os ,same oracle, after application and instant client installed,same problems got. so i'm think about is there any conflicts when oracle 10g and odac/instant client work together

If you have Oracle 10 installed on a Windows computer, you have oci.dll.
If "oci.dll can not be loaded", the problem is not a lack of oci.dll.
The first thing you should do is uninstall Instant Client and anything else you installed to fix the problem (I don't know what you mean with "install PL/SQL").
Then check if oci.dll can be loaded, e.g. by starting sqlplus and connecting to a database.
If that works, oci.dll is fine.
If your program cannot load oci.dll, something in your setup has a problem.
Maybe it cannot find oci.dll and you have to tell it where to look.

Cannot load OCI DLL: C:\oracle\product\11.1.0\db_1\BIN\oci.dll

Hi..
I tried connect to my oracle 11g using toad version 9.5.. but i got an error as below:-
Cannot load OCI DLL: C:\oracle\product\11.1.0\db_1\BIN\oci.dll
As your information.. this is my tnsnames.ora configuration:-
NV2DEV =

(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = NV2DEV)
Please help me...
Thank you,
Baharin

hi,
Guys, I installed Oracle 11g client because of the reported fix of System.Transactions issue known in 10g. I use PL/SQL developer, and it told me "Initialization error: Could not locate OCI dll", though the registry entry and ORAHOME folder it showed were Ok. It seems like PL/SQL developer was looking for OCI.dll not in the reported ORAHOME folder but in ORAHOME\bin folder. After copying all files (luckily, they are quite few) from ORAHOME root to bin PL/SQL developer began to work correctly.
from the following link
http://forums.oracle.com/forums/thread.jspa?threadID=620900
it will work for you
Thanks

Oracle 9iAS installation question-oci.dll error

Hi all
I have a question about 9iAS installation. Can we install 9iAS in NT??. I downloaded from the site, installation for NT. While installing I get error like "could not write oci.dll error"..I'm installing the portal and wireless type and I have my Oracle9i database installed on the same machine. Can anybody suggest how to rectify this error.
Thanks a lot

Are you trying to install in the same Oracle Home directory as the database? You should install in a different OH. Furthermore, 9iAS itself also installs in 2 OH's. You will end up with 3 OH's.
It is not a good idea to install the database and 9iAS on the same server, unless you have a really big one.

"unable to load wingenerator.dll" error message in Captivate 4

Has anyone run into the "unable to load wingenerator.dll" error message in Captivate 4. I didn't see this type of error in v3...so just wondering if it is an issue with this version. I have to save my project after every change in order to not loose my work. I get this error and then the program crashes without saving my work.

Hello Cat,
Welcome to our community. This sounds like the Windows registry has either become corrupt or has an incorrect permission. If you are using Windows XP then you might want to take a look at the following blog post

If you are using Windows Vista then I would suggest that you contact Adobe using the Adobe Captivate Feature Request/Bug Report Form

Cannot load OCI DLL: C:\oracle\product\10.2.0\db_1\bin\oci.dll

Hello,
my environment is:
MS Windows 2003 R2 SP2 Enterprise x64 Edition
Oracle Database 10g Release 10.2.0.1.0 - 64bit Production
and I want to use:
TOAD for Oracle Freeware - version 8.5.0.50 g (from Quest Software)
my "path" variable is as below:
C:\Documents and Settings\Administrator.SERVER2003>set path
Path=C:\oracle\product\10.2.0\db_1\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
At location "C:\oracle\product\10.2.0\db_1\bin\" I can see "oci.dll"
BUT... when I try to connect to my database... from TOAD... I get the message below.
Cannot load OCI DLL: C:\oracle\product\10.2.0\db_1\bin\oci.dll
Using "netca" or "sqlplus" I can connect to the database with success.
Help welcome!!!

Hummm....
this should be the cause.
I have Oracle Database 10g Release 10.2.0.1.0 - 64bit Production. Then all the executables including DLLs are 64-bit version compiled.
Now... I guess that the TOAD software is 32-bit application and it can not load 64-bit OCI.DLL.
Thanks to EVERYBODY evolved!!!
By the way:
The TOAD for Oracle Freeware - version 8.5.0.50 g (from Quest Software) is the latest version available from Quest Software.

OCI.DLL error

My application install Oracle OLEDB and instant Client 11g, with "ODAC 11.2 Release 5 (11.2.0.3.20) with Xcopy Deployment" the connection work well in hundred of installations, except :
On a single machine and only on it, with Win7 32 bit I have a particular problem, when i try to active an ADOconnection Object , an error appear :
"The procedure entry point lxgutf2ucs could not be located in the dynamic link library OCI.DLL"
Any Idea ??
thanks Mirko

I'd guess the wrong OCI.dll is being loaded.
Use Process Explorer from http://sysinternals.com to verify where it's being loaded from. You'll probably see it's not the one you expect.
Once you've verified exactly what OCI.dll is being loaded, you can see the entry points with Dependency Walker from http://dependencywalker.com
Hope it helps

Firefox starts with a "could not load xpcom.dll" error.

When I open Firefox, I sometimes get the error message as per subject. It only happens 1 out of 10 times. When I acknowledge this error message and open Firefox again, it works with no errors seen. Now, I've seen this issue posted many times on these forums but none solve the issue or have an acceptable answer.
- I do not have Firefox in my startup folder.
- I cannot do a clean uninstall as I have a plethora of add-ons, extensions and settings.
What causes this error and how can I fix it permanently?
Thanks for reading.

Note that the xpcom.dll file is no longer present in current Firefox versions, so you may have an extension or other software that needs to be updated for the current release.
*Bug 852950 - Kill xpcom.dll/libxpcom.so/xpcom.dylib
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

Cannot load oraclient9.dll error

Hi Experts,
I am facing below error when connecting to toad, while oracle 10g is installed in the system
Cannot load oraclient9.dllThanks in advance

If you have a paid for edition of TOAD then perhaps you have a support contract? In which case you could try the official support portal, which is now on the Dell site. [url https://support.quest.com/productinformation.aspx?n=268435520,4294956418] Find it here.
Otherwise you can try the TOAD forum, [url http://toadfororacle.com/forumindex.jspa?categoryID=649]which is here.

Error while creating database - Cannot load backend library 'oci.dll'

Hi all,
I am newbie to Timesten imdb (in memory database). I do not wish to use oracle rdbms.
I have installed the Timesten IMDB on Win2003.
E:\TimesTen\tt70_32\bin>ttVersion.exe
TimesTen Release 7.0.5.0.0 (32 bit NT) (tt70_32:17000) 2008-04-05T00:54:16Z
Instance admin: m4sadm
Instance home directory: e:\TimesTen\tt70_32
Daemon home directory: e:\TimesTen\tt70_32\srv\info
While installing, I followed the viewlet at: [http://www.oracle.com/technology/products/timesten/viewlets/tt70_install_win_viewlet_swf.html]
Now, I am planning to create a database, and so following the viewlet at: [http://www.oracle.com/technology/products/timesten/viewlets/tt70_create_db_win_cc_viewlet_swf.html]
However, when I give the command (according to the viewlet), I get the following error:
Command> select * from v$version;
5102: Cannot load backend library 'oci.dll' for Cache Connect. OS error message '<empty>'.
The command failed.
Can anyone provide pointers to resolve this?

I'm guessing you chose No to the install question about using Cache Connect to Oracle? This would cause certain libraries not to be installed at install time, specifically libraries that would enable you to use TimesTen Cache Connect to cache data from Oracle tables.
The table "v$version" that you use in your select
select * from v$version
only exists on an Oracle RDBMS. It doesn't exist on TimesTen. Moreover the second viewlet you refer to is about using the TimesTen Cache Connect feature to cache tables from Oracle RDBMS. If you're not interested in using Oracle RDBMS, as you say, it would be my assumption that you're also not interested in using the TimesTen Cache Connect feature? So I'm a little confused here about your intentions. Are you interested in using TimesTen as a standalone datastore, or do you want to use it to cache data from tables located in an Oracle RDBMS?
Thanks.
