Establish 32-bit ODBC connection to 64-bit Oracle 11g database

Hi Everyone,
Just to set the scene:
PC with Windows 2003 server x64 OS installed, Oracle 11g 11.1.0.7 64-bit installed and MS Office 2007 installed.
I am looking for advice on the best way to establish an ODBC link so that MS Access 2007 (32-bit) can connect to the Oracle 11g (64-bit) database.
There are known issues, see [http://support.microsoft.com/kb/942976|http://support.microsoft.com/kb/942976] (which I have hit) when attempting to use a 64-bit ODBC DSN within MS Access 2007. This means that I need to setup and install an Oracle 11g 32-bit ODBC driver to be used against the Oracle 11g database (TNS listener also running 64-bit).
Any thoughts on the best approach I should take to do this?
Regards,
Leigh.

The more information section of the MS support article doesn't give me much to go on other than to explain the differences in how user and system DSNs are displayed and managed between the 2 different bit versions of ODBC administrator and how this information is stored in the different registries (64-bit and WOW64).
I have been able to install 32-bit Oracle11g instantclient and its ODBC driver successfully and then in turn create the 32-bit ODBC DSN, however I am unable to connect to the 64-bit database when I attempt to test the DSN. I have updated the Windows PATH environment variable to include both the path of the Oracle11g DB server and instantclient homes as well as creating a TNS_ADMIN environment variable to point to the location of the Oracle11g TNSNAMES.ORA and the 64-bit 11g listener. However despite this I still get the error when testing the DSN:
Unable to connect
SQLState=S1000
[Oracle][ODBC][Ora]ORA-12541: TNS:no listener

Oracle 11G database for 64 bit windows installation error

Hi,
I downloaded the 11G 64bit for windows and unzipped the files into one folder and ran the setup.exe as an administrator. It opened up the java screen and I chose, create and configure a database. Next screen I chose, Desktop Class, when I click next it dies. It does not show me teh next screen. I went to the appdata folder and saw this error but not sure what to do EXCEPTION_ACCESS_VIOLATION (0xc0000005). Please help. Thanks for your time and help.

Issue in Connecting to Oracle 11g Database

Hi,
I have installed Oracle 11g database using loopback adapter. (used ip 10.10.10.10). In the drivers file did the following entry
ipaddress computername.domainname.com computername
How can I connect to this database from other computer in the network ex:using sqldeveloper? (When I try it says "Network adapter couldnt establish the connection")
Thanks,
Ramesh

from other computer in the network Oracle version on that computer ?
Did you configure a connection string on that computer ? If so, please post your tnsnames.ora. If not, what did you do exactly ?
Also, from the server post the result of "lsnrctl stat".

Failover not working while connecting to Oracle 11g database

Hi,
We have a J2EE application that connects to Oracle 11g database.
The connection URL we are using is as below
jdbc:oracle:thin:@(DESCRIPTION =(SDU=32768)(ADDRESS=(PROTOCOL=TCP)(HOST=abc.hostname.com)(PORT=1525))(ADDRESS=(PROTOCOL=TCP)(HOST= xyz.hostname.com)(PORT=1525))(CONNECT_DATA=(SERVICE_NAME=PQR)))
The issue that we are facing is, the database failover is not working.The application only connects to the first host in the TNS entry.Evertime there is a failure in the connection to the first host,manual steps are required to swap the hosts.
This started happening after we upgraded Oracle DB from 9i to 11g.
We are using the client jar of 9i to connect to 11g. Could this be causing the problem?
Thanks In Advance.

Yes, you are right. Nothing else was updated.
The application still works as expected except the failover.If you are correct then I seriously doubt it has anything to do with java. It would be something to do with Oracle and/or network infrastructure.
If not then it is some small problem with the driver. You can try updating the driver but I wouldn't expect a fix.

Not able to connect to oracle 11g database source through OBI Server

Hi,
I am having an issue regarding the database connectivity.
Iam unable to connect to the oracle 11g database through OBI server. However its connecting through SQL Plus with same username/password@hoststring. Its giving the error as :
[nQSError: 17001]Oracle Error code:1017,message:ORA-01017: invalid username/password; logon denied at OCI call OCILogon
[nQSError: 17014]Could not connect to Oracle database.
Please help me out in resolving the issue.

If it's working in one place and not the other then it's obviously not an OBIEE problem.
Are you typing it in right??
Do you have multiple tnsnames.ora files pointing to different databases, maybe sqlplus is picking up one and toad & OBIEE the other and so the username/pw is wrong for that database?
There's a limited amount that can be said to help, as the error is 100% clear what the problem is :) it's just working out whether you're connecting to the database that you think you are connecting to, and then whether the username & PW you're entering is correct for that DB.
BTW OBIEE 10.1.3.4 is supported with 11g, and we're using it without problem here.

Forms 6i is not connecting with Oracle 11g database?

Forms 6i is not connecting with Oracle 11g database?
How to resolve this issue?

Hi,
Once you installed the Forms and Reports, you need to configure the paramters like tnsnames.ora in you path.
There will be one folder in the Installation path of Forms and Reports search for tnsnames.ora file..and you need to Updated the file as per the which ORACLE Server you are connecting and then try.. it..
Default path for forms will be "ORACLE_HOME/net80/admin".. search for tnsnames.ora and modify it..

32 bit vs 64 bit odbc connection problems

Good morning,
I am trying to connect a powershell script that worked fine on a 32 bit system, but now will not work on a 64 bit system. This script connects to a odbc connection and connects to a remedy ticket system and pulls information to move over to my Outlook
calendar.
The error am getting is:
Exception calling "Open" with "0" argument(s): "ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application"

The code that is running this is below:

I would appreciate it if someone had some insight to offer. I've looked around and have created the ODBC connection on the 32 bit odbc version c:\windows\sysWOW64\odbcad32.exe. Doesn't seem to have changed anything. Ive created it both
as a user and system DSN.

Add the below code in to your Script.
if ([environment]::Is64BitProcess -eq $True)
C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -File "script filename"
Exit
Note: The path I used is for Windows 7, you need to figure out the path for your OS.

Oracle 11g Database 64-bit, Client 32-bit

Hi,
I have a problem,
I have an IBM Sever with 64-bit processors.
On it there is a Windows Server 2008 also 64-bit. I've installed Oracle Client 11g 64-bit. And there is my problem.
I can't connect to this database using tools like SQLTools or BDE Administrator. I can only connect via SQL PLUS (which is installed with Oracle). Also with installed Client 11g 32-bit on Windows XP 32-bit(connected via LAN) I can't connect.
While trying to open SQLTools there is a problem with some .dll (I can't remember now what's this .dll, definitely not OCI.dll).
Reinstalling programs doesn't help.
Another problem I have is with HP ProLiant Server. It's also 64-bit installation.
Also Win Server 2008 and Oracle 11g 64-bit. On it is the same problem, but the information while starting SQLTools is a problem with OCI.dll . Also reinstalling is not helping.
Do you guys have any idea, what's wrong??
Cheers...

Just to try to determine if it is a bit-level issue (which it shouldn't be--this has never been a problem for me in the past), try installing 32-bit Oracle client on a workstation and seeing if you can connect.
I agree with the above poster, who said these tools might not be compatible with Oracle 11--they might be looking at different data dictionary views or something similar.

How to create an odbc connections to LMS 4.0.1 database

Does anyone know how to connect to the LMS database (preferably from a machine other than the actual LMS server) to access the database - ani, rmeng etc. I was able to do this on my LMS 2.2 version, but can't seem to figure out how to do it with this version.
I want to create an automated inventory file, taking fields from LMS' db's and merging it with other mgmt. software db's. I know all the fields etc. that I want, but don't know how to made the odbc connections.
Any help will be appreciated.
Thanks,

I believe this document covers what you are asking about in great detail.

Building an ODBC connection to Outlook Business Contact Manager database.

If you are using ODBC then you need to create a DSN in the ODBC administrator first. Then in Crystal select ODBC (RDO) under create new connection, this will list all of your ODBC DSNs.

What I do wrong? Please help me

Hi,
You can download the 11.1.0.7 patchset from My Oracle Support -
support.oracle.com
as patch 6890831.
Once logged in click on 'Patches and Updates' and enter the patch number as 6890831 and choose whichever platform you are running.
the readme explains how to apply the patch to an existing 11.1.0.6 install.
The url you posted is only for complete product installs, but 11.1.0.7 is only a patchset that must be applied to an existing install.
Regards,
Mike

Oracle 11g database Connection & Response are very slow

I have an ORACLE 11g R2 on lRed Hat Enterprise Linux Server release 5.3 (Tikanga).
initially it was working fine.
Now a days while attempting to connect into the database from network using @service_name
it takes a lot of time to establish the connection and even it gets connected the query response time is very high.
on the other hand if I connect from the native database machine's terminal without @service_name it works fine & the response time is convincing. But even from the native database machine's terminal with @service_name it is giving me the same pain.
can any body help me how to fix this.
Thanks in advance..
