I am attempting to connect to an Oracle 8i database via the Oracle 9.02 ODBC driver and I am receiving the following error message upon testing the connection in WinXp's ODBC Data Source Administrator dialog box: "Unable to connect SQLState=IM004 [[Microsoft]][[ODBC Driver Manager]] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed"
I am running Oracle Client 9.2 on a P4 machine running winXP. Has anyone out there experienced this issue before? Anyone have an idea on how to resolve it? Any assistance would be greatly appreciated. Thanks.

Are you sure you're using Oracle's odbc driver? xp sometimes comes with the microsoft's odbc driver for oracle. I wouldn't recommend using that.
On the other hand if you're already using oracle odbc driver, try using oracle 8i driver (8.1.7) instead.

I'm use windows server2000 and oracle 9.2 and also receive the same error message.
when use "Microsoft ODBC for Oracle" driver get the error:[[Microsoft]][[ODBC Driver Manager]] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed;

when use "Oracle in OraHome92" driver get the error:[[Microsoft]][[ODBC Driver Manager]] Specified driver could not be loaded due to system error 5;

I solved the problem by add the IUSR_mycomputername user to administrator group.

One of the things that causes this error is not having the ORACLE_HOMEbin directory in your path.

This is usually added during the install of the oracle client. But if you install the client and then the ODBC driver in the same session, the path may not take effect immediately, and so the ODBC connection test fails. This happenned to me and the problem went away once I'd logged off and logged on again.

Open up a cmd prompt and check the path in that.

This was solved when we FIXED the path statement in Windows 2000. The path statement was broken and read off with a dot (".") and no semicolon followed it as a delimiter.

For Example:
WRONG--> .C:WINNTSystem32
RIGHT--> .;C:WINNTSystem32

The problem appears to be a permission issue during the installation of both Oracle 9i and 10G.

If you navigate Oracle home you will find that the directory has different permissions then the root of the tree. In the case of 10G the path is C:Oracleproduct10.1.0Client_1. Open the properties for the Client_X directory, and you will see that "Authenticated Users" should have Read and Execute, List Folder Contents, and Read. To fix the problem, do the following....
-Select Authenticated Users
-Uncheck Read and Execute
-Press Apply
-Check Read and Execute
-Press Apply

Seems stupid, but that did the trick for me. I ran across this solution on asp-help.com.

Where I found the solution

"That did the trick" thanks. I never would have thought of doing that.
Here are my steps I took:
1)Opened up Windows Explorer
2)Navigated to Oracleora92
3)Right clicked and selected properties
4)Clicked on Securities tab
5)Clicked on Authenticated Users
6)Unchecked Read and Execute
7)Rechecked Read and Execute
8)Clicked ok to close window
9)Restarted web server
10)No longer get the error message

All of the other message boards kept saying it was a path issue and that did not appear to be the case for me.
Once again, thanks.

Great catch. I was pounding on this problem all day.

We had to reboot after following the directions for IIS to accept the changes.

It worked for me as well with one small caveat: after rechecking Read and Execute I had to reboot my laptop that runs Win2000. Otherwise the change had no effect.

Thanks a lot. The message was really useful. Before finding this answer I was really frustrated.

Adding the Oracle Home\bin to the PATH variable in Win2k did the trick for me.

I had just installed oracle forms 10.0.1.0.2 which instaigated this error message on existing ODBC connections.

I am using XP and 10g.

I fixed it by moving my ORACLEHOME/bin infront of my DEVSUITE/bin entry in the PATH variable

It works after changing the path to include Oracle installation directory.

Thanks thunderfunk for your valuable advise.

I was able to resolve it by adding the oracle home (C:\oracle\ora92) and path C:\oracle\ora92\bin.

I too faced the same problem.
It was because ORACLE_HOME environment home was blank.
I set it to point to the correct location & it started working.

You added the home and path to where? I am having a similar problem. As an administrator, I get no errors. Once I remove the admin permisssions and return the account to the user group, I get the [Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed. I have tried removing the permissions from the Oracle folder and then adding the read & execute back. Because it works as an admin and not as a user, I know it is a permissions issue. I have updated permissions on the oracle, odbc, and the software interface, giving the user group admin rights. I am running out of ideas. I am open to suggestions.

Thanks,

CaptainPC

CaptainPC,
I applaud the fact that you actually searched for previous solution here & found a 3 year old thread.
To utilize Oracle s/w on a local system one of two ways will succeed.
1) You are the owner of the Oracle software
2) You utilize SQL*Net (username/password@TNS_ALIAS) to access the DB

Attempting #2 requires the Oracle listener to be running & properly configured.

It would be helpful if you followed Posting Guidelines - http://www.orafaq.com/forum/t/88153/0/

Just a summary of all the above discussions
Assume Oracle Client in c:\OraClient folder and web folder as c:\inetpub\wwwroot

1. c:\inetpub\wwwroot must have Read and Execute privlege for IUSR user.

2. c:\OraClient must have Read and Execute privlege for IUSR user.

3. The environment PATH variable must have C:\OraClient\bin included.

4. Don't forget to restart Web Server

I HAD FIGURED OUT ANOTHER WAY IN WINDOWS 10 PRO. ANS:

GO TO "Control Panel\All Control Panel Items\Administrative Tools" WITHOUT QUOTES. OPEN LOCAL SECURITY POLICY -> LOCAL POLICIES -> SECURITY OPTIONS -> choose to disable "User Account Control: Run all administrators in Admin Approval Mode".

also go to win+R type UAC AND turn off. Restart your computer and see.

My issue was after upgrading to Windows 10 Pro from Windows 7 64-bit i was not able to connect
1. SQLPLUSW with schema it vanishes.
2. Custom Program report with Visual Basic 6.0 (frontend) and Crystal Report (backend) throws an error such as "Driver's sqlallochandle on sql_handle_env failed"
3. if I go to administrative tools and give DSN on ODBC Data Source Administrator (32-bit) also gives same error. ie., on Oracle in OraClient 10g_home1
4. Can't run Visual Basic 6.0 with same program which is previously running fine in windows 7 64-bit.
