Unable to Connect SQLState IM004 MS ODBC Driver Manager SQLAllocHandle on SQL_Handle_Env failed
Posted on 2007-10-04
We have a Windows 2000 Server that has Oracle 9.2 installed on it. We run an ASP Application on it. This morning users were getting the error - tns could not resolve service name on the ASP pages. When I try to "test" the odbc dsn using ODBC Data Source Administrator I get the following error -
Unable to connect
[ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed
As far as I know nothing has been changed on this server - no updates, no one messed with the tnsnames.ora file, etc. We have another server (similar in configuration) that is hosting the ASP app now and it has no issues connecting with the databases.
I have looked at the following -
System Environment Variables - the oracle home bin directory is there in the path (I have compared it with the other server that's working and they are the same)
Permissions for the Oracle folder - Administrators and Authenticated Users had access and I have now added the IUSR_machinename and IWAM_machinename as well
Is there anything else I can check? Not sure if ths is related but while rebooting the server I got a message saying one of the services had failed to start - when I looked at the event viewer it had the following - WMI ADAP was unable to process the RemoteAccess performance library due to a time violation in the open function (EventID 61)
Any help would be appreciated. Thanks.
