Cannot get ODBC data source to talk to Oracle 10g for Windows

Problem description
I recently installed Oracle 10g on my laptop computer, which is running Windows 7. Everything went smoothly except for one crucial item: The ODBC data source I added keeps returning this error when I click the "Test Connection" button:
Testing Connection
Unable to connect
[Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed.
I was using the following ODBC driver
Oracle in OraDb10g_home1 (TNS Service Name = ORCL and User ID = scott)
This type of error happened, in one form or another for the three other Oracle drivers I have on my machine
Microsoft ODBC for Oracle
WinSQL Oracle
WinSQL Oracle Wire Protocol
These services are currently running (status = Started)
OractDBConsoleorcl
OracleMTSRecoveryService
OracleOraDb10g_home1iSQL*Plus
OracleOraDb10g_home1TNSListener
OracleServiceORCL
(NOTE: I entered the foregoing information by hand, since I was not able to copy-and-paste it. So be aware that there is a small possibility of a minor typo in case you plan to cut-and-paste it.)
If requested, I can provide the contents of these files
tnsnames.ora
sqlnet.ora
listener.ora
Other installations on the same computer
ODAC (ADO data provider for Oracle)
SQL Server 2009 Express
.NET 4
Visual Studio 2010
Any help would be greatly appreciated!

OK, I went ahead and upgraded to Windows 7 Professional and I STILL get the same error messages when trying to get the Oracle ODBC driver to talk to Oracle 10g. Here are some screen shots that show what happened:
1) Select ODBC driver: http://yfrog.com/f3driverselectionp
2) Configure driver: http://yfrog.com/ccoracleodbcfororaclep
3) Test connection: http://yfrog.com/1goracleodbcfororacletestp
I also get the following error when I try to run SQL*Plus from the line command, even with no parameters:
C:\Users\Bruce>sqlplus
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
Any suggestions as to how I might to go about diagnosing (and fixing) this problem?
Thanks,
Bruce

Cannot get ODBC Data Source to connect on report server

Hi,
I have an ODBC Connection installed on our PROD server that when you test through I-SQL and the ODBC Administrator it works.
When I add a new data source to the reporting server we interface and press test connection it just hangs for ages then gives a page cannot be displayed.
I have installed all the same on the DEV server and it works fine. I have set all of the configs to exactly the same!
I feel like something to do with reporting services is not correct. Any one have any ideas?
Thanks.

Hi KMoff,
Per my understanding that you are using the ODBC datasource type and when you have set the connection string and click the "Test Connection" it hangs and got some error, right?
Please find the details steps below and try to provide more information according to the questions:
Whether the error message you got is "page cannot be displayed", if not, please try to provide more details inforamtion.
Did you got the error message when you click on the "Test Connection" from designer or report manager.
If you got the issue only in the report manager, the issue can be caused by the support of the ODBC driver in the report manager and also the bit.
Standard .NET Framework data providers do not necessarily support all the functionality supplied by Reporting Services data processing extensions. In addition, some OLE DB data providers and ODBC drivers can be used to author and preview reports, but are not
designed to support reports published on a report server. See
Data Sources Supported by Reporting Services (SSRS)
When you deploy a report to a 64-bit report server (x86), the report server must have natively compiled 64-bit data providers installed. Wrapping a 32-bit data provider in 64-bit interfaces is not supported.
Could you provide more details information about the connection string you are currently using.(Excel files or something else)

Problem opening ODBC data source in Windows 2003

I am having difficulty opening a ODBC data source in SQL
Server 2000 running on Windows 2003 using ColdFusion MX7 (it works
cleanly on the same database on windows 2000 server). Anyone has
any ideas.

Here it is, there is an issue with our Search functionality with the new SDN:
Symptom
When setting location on a Crystal Reports XI Report using the Progress OpenEdge ODBC Driver in Crystal Reports 2008 or Crystal Reports 2011 get “Some tables could not be replaced, as no match was found in the new data source. Please specify the table required for any unmodified tables.”
Environment
Crystal Reports 2008 or 2011
Progress OpenEdge ODBC Driver
Reproducing the Issue
Open a Crystal Report created in CR XI Report using the Progress OpenEdge ODBC Driver in Crystal Reports 2008 or 2011
Set location to a new ODBC Data Source
Get error "some tables could not be replaced, as no match was found in the new data source. Please specify the table required for any unmodified tables.”
Cause
Crystal Reports XI only creates aliases for tables with special characters or duplicate names.
Crystal Reports 2008 introduces a change which requires aliases for all tables.
Aliases are not created when doing a Set Location on the whole data source.
If a Customer has hundreds of reports they cannot set location of each table and fix the aliases.
Resolution
Upgrade to Crystal Reports 2011 Support Pack 02 or higher
Under registry key [HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Suite XI 4.0\Crystal Reports\Database\ODBC] create string UseTableNameAsAlias and set it to PGPRO1019.DLL, PGOE1022.DLL. Registry file is attached.

What is the planed release date for 10g for Windows?

Hi,
10g fo HP and Sparc is already out, but windows not yet. Is it known what is the planed release date for Oracle 10g for Windows?
TIA,

On the other hand it's just somewhat funny for me, that it looks as if marketing woudl decide which platform is released first. Some times it is Linux, some times it is Solaris and then again it is Windows. You simply can never know.

Excel-2007 cannot connect to Oracle ODBC data source, Control Panel can.


I cannot make an ODBC connection from Exce-2007 to Oracle work. I am an expert Excel and VBA user (since 1994) and I have frequently used Excel to access ODBC databases, including Oracle (I have done this with Excel-2003 both with worksheet queries and have written VBA ADO-connection routines). And even though in Excel-2007 a worksheet ODBC query is supposed to be easier to create than in previous version of Excel, my connection fails. Any suggestions and all help are welcome and much appreciated.
DETAILS


1) What is my system? I am using Excel-2007 on Windows Vista x64 and Oracle server v.11g on my computer (all this is on my computer, no network issues).
2) Why use Excel with Oracle at all? I use Excel-2007 to access Oracle rather than Access-2007 (or any other application like TOAD, etc.) because I do engineering calculations with the data stored in Oracle. These calculations are easier done in Excel (I suppose that one alternative to this could be to use some sql or Access to get the data from the database, then store it as plain vanilla CSV file, then open this file in Excel, then do the math (the math involves complex optimisation algorithms), then save the results as CSV, then use some sql or Access to put the data back into the database. Howwever this does not strike me as a quick or neat solution. And after all Excel has been designed to access ODBC databases, so why not use it?)
3) What do I do in Excel-2007 that won't work? I create an ODBC link to Oracle that does not work. In Excel-2007 this is straightforward:

<ul>
<li>define an ODBC connection (Data tab --> From other sources --> From data connection wizard);</li>
<li>define a query on the worksheet -- that's it, this is all!</li>
</ul>

I start with creating an ODBC connection:
a) I choose an ODBC data source type: ODBC DSN
b) Excel-2007 displays the list of the available ODBC data sources. I see in it my Oracle database name and I select it.
c) Excel-2007 displays the Data Link Properties:
- the "Provider" has a list of the OLE DB drivers with preselected "Microsoft OLE DB Provider for ODBC Drivers". I keep this default selection.
- the "Connection" tab has a connection string "DSN=<my database name>" which I keep, it also has fields for the user name and the password, which I fill with the correct credentials.
- Finally there is a button "Test Connection", which when I click produces the following error message:
"Test connection failed because of an error in initializing provider. 
Unespecified error"

4) Additional food for thought:
a) In the above walk-through the only data, which I type, are the user name and password, everything else is selected from lists offered by Excel-2007, hence any possibility of typos being the cause of the problem can safely be discarded.
b) I can test the ODBC driver in the Control Panel and it shows that it can connect to the Oracle database:
- in Control Panel --> Admin Tools --> Data Sources (ODBC) on the "User DSN" tab I can see the list of the available ODBC data sources (same list as in Excel-2007, point 3b above) with the name of my database in it;
- selecting the name of my database from the list of the sources and clicking "Configure" button opens a tab with Data Source Name (same as in Excel-2007), TNS Service Name and User ID. I enter <user name>/<password> and click "Test Connection" button. A message "Connection successful" appears (just for a test I enter incorrect user credentials and "Unable to connect" message appears)
BOTTOM LINE


The procedure for using an ODBC connection from Excel is very simple, in the past I have created and used such connections numerous times with Excel-2003 and earlier on Win-XP and earlier. But now on Excel-2007 and Vista-x64 I cannot make it work.
Also, testing an ODBC connection driver is really easy and simple to be done in the Control Panel. There testing the same ODBC connection, which fails in Excel-2007, results in success.
I am frustrated by the simplicity of the problem and yet the persistant error. I have lost now two full days in failed attempts to make the simple procedure work and in searching the internet for answers.
All help is highly appreciated <img class="emoticon" src="images/emoticons/happy.gif" border="0" alt="" width="16" height="16" />,

Did you find the solution to your problem?
If not, I think I may know.
Excel 2007 is a 32-bit application.
When installing 32-bit applications in a 64-bit environment, the "default" location is:
C:\Program files (x86)\...
Excel then launches from this location.
However, when it connects to Oracle and passes the name of the calling program, Oracle attempts to "interpret" the value of (x86) as if
the value within the parenthesis are being passed as a reference. Of course, iOracle doesn't find anything, so the result is (),
and then it cannot return the connection info back to the calling application.
I corrected it by installing Excel in C:\Program Files\, and once launched from that location, it works the same as on the 32-bit machines.
However, at my location, they are FORCING Excel to be installed in the(x86) location.
What I'm trying to discover now is:
Is it possible to flag Oracle to NOT process the embedded variables?
Or, is it possible to assign a variable in Oracle such that x86 = "(x86)", so that the end result is viable?
Have you had any luck with your installation?
thanks,
Paul

Cannot see System DSN ODBC Data source (however user DSN is Ok)

We have installed BO 6.5.1 on Windows 2008 R2 64 bit and set up ODBC Data source to the existing SQL server.
When we try to set the BO up (Administration>Safe recovery etc.), in the "Database middleware selection" - "Define new connection" - "Data source name" we cannot see the System DSN name that we've created in the Window's "ODBC data source administration" control panel applet. If we create a User DSN, we can see it ok but it works for one user only (as it should).
So, in a nutshell, if we setup a User DSN it works fine but if we setup a system-wide System DSN BO cannot see it. I've got no idea why...
Can anyone point me to the right direction, please?

Are you using the ODBC Administrator from control panel? If so, try launching this instead: odbcad32.exe from start/run.
This is the 32-bit ODBC administrator and since we are a 32-bit application, a 32-bit DSN will need to be configured.

Using Excel & ODBC data source to get data

I've been using MS Excel to extract MS SQL Server data from our ERP system for years but we are now moving to Oracle 12i. What are my options in the Oracle world? Can it be configured much the same way; that is by configuring an ODBC data source and connecting directly to the database???
Thanks in advance.

ODBC Data Source Error

I was having with Crystal communicating with one of my Access databases that had a list box. In Crystal it would take the list box, add and remove letters. It was suggested that I check with my IT department to see if there are any updates. Well they upgraded me from Crystal XI to Crystal XI R2. Things have gone downhill from there. First I couldnu2019t even open the program and they ended up reinstalling everything again. Now I can open Crystal, but all reports I previously created and new ones I try to create cannot make any connection through ODBC. My IT person and I have tried several things even installing a couple new drivers. My IT department does not provide technical support for software so now Iu2019m on my own to figure this out. If anyone can provide me with any assistance or any suggestions where to check I would greatly appreciate it.
My problem is any time I try to make an ODBC connection to either create or update a report I go through the steps and get an error at the connection information page and cannot go any further. This error happens with MS Access or MS Excel. The error is "Login Failed. Details: Cannot obtain error message from server. I have no logins or passwords.

In the Organizer workspace, do a
File > Catalog > Recover
command. That command "cleans up" your Elements catalog and often resolves ODBC data source error messages.

Instant client installation unavailable in ODBC data sources

I'm trying to install instant client to enable MS Excel to access an Oracle database. OS is Windows 7.
After installing instant client plus the odbc package, I can't see a new entry in the odbc data sources - only the standard Microsoft sources (Excel, Access, SQL Server) show up.
There's also an Oracle SQL developer installation on my computer. Connection to the database works fine in SQL developer - so the DB does exist and it is accessible.
Steps conducted during instant client installation:
- Downloaded basic lite instant client (11.2.0.3.0) for windows.x64
- Downloaded odbc package for windows.x64
- unpacked zip file to instantclient directory
- executed the odbc_install.exe in the instantclient directory. I'm not sure if this install.exe does anything at all. There was no error message but also no confirmation or reaction of any kind.
- executing the install file from the cmd window gave me a message, that the odbc drivers were already installed. So I guess odbc_install.exe was executed properly
- setting some system variables
     1) path variable: added instantclient directory to the ones already listed in path
     2) tns_admin: new entry, pointing to instantclient directory
     3) ld_library_path: new entry, pointing to instantclient directory
- wrote an tnsnames.ora file using the connect information also used in SQL developer
- saved tnsnames.ora file in instantclient directory
- rebooted computer to activate changes
When opening the odbc data source administration, I'm only able to see Microsoft drivers for Access, Excel, SQL Server. I'd expect to get an Oracle driver option to add to the installed drivers.
Wild & uneducated guesses about what might cause the problem:
- IC is installed on E: drive. Maybe some component is expected to be saved on C: (low likelihood, many others would have complained by now)
- Win 7 often asks for explicit permission to do this or that via popup windows. Maybe the odbc-component encounters such a request ans says "Ummm....???"
Any idea, what I might try to get an oracle entry in the odbc data source list?
Best regards
Peter

I'm not sure to be honest, but what I downloaded did not have a setup.exe.
Does what you're talking about allow you to connect to Oracle databases via ODBC? If so, is it downloadble from the Oracle site?

ODBC Data source administrator hanging for 20 seconds

After installing 32 bit ODAC 11.2 Release 5 and Oracle Developer Tools for Visual Studio (11.2.0.3.20) our business is reporting slow Excel/VBA code using ODBC.
The business are querying using a ODBC System DSN. It works but hangs for 20 second when VBA releases the connection.
I can see that I get the same pause after testing the connection in the "ODBC Data Source administrator"
1. Open ODBC Data Source administrator
2. Edit the System DSN
3. Push "Test Conncetion". Says "Connection succesful". Push OK
4. Push "OK"
ODBC Data Source administrator now hangs for 20 seconds.
I did a clean installation on a Win7 x64 machine using 32 bit ODBC Data Source administrator
Nothing to find in the eventlog.
Does anyone know what could be wrong?

Udpate: I tracked it down to Microsoft ISA Firewall Client installation. If I uninstall the ISA Firewall the problem disappears.
Only disabling the ISA Firewall doesn't help!

How can I delete an ODBC data source after 10g client has been uninstalled?

I uninstalled the 10g client and now when I attempt to delete the ODBC data source, I get an error: "The setup routines for the Oracle in Oraclient10g_home2 ODBC driver could not be found. Please reinstall the driver. I re-installed the client and I get the same error, but I had to specify a new home. I still get the error. Anyone have an answer or a workaround to deleting the ODBC entry so that I can re-create with the same name later under the 9i client?

I have the same problem... and nobody gots the point:
1st. the ODBC and the client/home exists on the machine...
2nd. the client/home is unistalled and so...
3rd. tada! Now we have a impossible-to-unistall ODBC entry!
That is happening on a Windows, at last to me...
Please, help us if someone knows how to remove this ODBC entry... if know how to DO the stuff (permissions, system, all that things is answered above).

ODBC Data Source Won't Recover from Connection Errors

I have several ODBC data sources to a mainframe and want to
use the "Maintain Connections" setting as it dramatically improves
performance under heavy load. Problem is that we frequently have
path problems between the CF server and the mainframe 180 miles
away. With the Maintain Connections checked, the data source
doesn't consistently start working again after the path problem
clears up. The path problem usually only lasts a minute or two, but
SOME queries through the affected data sources continue to raise
errors until the ODBC Service is cycled. The SOME aspect is really
weird because not every hit through that data source reports an
error after the path comes back up. I've had side-by-side users hit
the same page using that DS and one consistently get's an error and
the other works fine. Restarting the ODBC service clears the
problem so it works fine for everybody. Of course that breaks all
the connections that were still working so I just affected a bunch
more users. Silver lining there is that at least nobody can claim
preferential treatment right. It's also kind of bizzare that I can
use the CF Administrator to verify all data sources and they
usually all report that they are working fine even while some
connections are still reporting problems.
The specific ODBC drivers we are using are Neon Shadow
Drivers (Multi Threaded). I'm thinking about using the Admin API to
hit the Disable Connections and then re-enable it.
Any constructive, tactful input for addressing this problem
would be appreciated.

Do you have a JDBC Type 4 alternative for these drivers? I
got rid of
all my datasource problems long ago when I got rid of ODBC
altogether.
