I have an vb6 application working using Oracle 10g which uses oo4o to connect with database.
Oracle 10g is installed on remote Database server.
But i don't know how to setting on client PC to run vb6 application.
(When I run it, it shows error msg "ora-12154 tns could not resolve service name")
Please help me the way (step by step) to setting on client PC to vb6 application can be connected to oracle database.
Regards

I am attempting to create a Sql Server Analysis Services Tabular Model and am having trouble accessing an Oracle database for importing data. I am using the following:
OS
-Windows 10 Enterprise (I am administrator of machine)
Tools to create tabluar cube:
-Visual Studio Community 2022 (64 bit) - Current Version 17.2.5
-SQL Server Analysis Services 15.0.2000.5 - Developer Edition (installed on localhost, services running)
Oracle database:
Oracle Database 21c Enterprise Edition Release 21.0.0.0.0 Production Version 21.3.0.0.0 - Developer Edition (installed on localhost), up and running and able to connect with other tools (e.g. Toad, Sqlplus, SqlDeveloper, cx_python, etc..)
I have a 64-Bit System Data Source Name created for ODBC connections, using Oracle Instant Client. This data source works just fine with other tools mentioned in the Oracle databse section above.
When creating a SSAS tabular model in Visual Studio and attemping to import a data source, I try the following:
Models
-TabularProject (my project)
-Data Sources > New Data Source > Oracle Database
At this point I get the following message:
Oracle Database
The recommended provider ('Oracle.DataAccess.Client') is not installed. You can continue with your current provider, however, it has been deprecated and may not work correctly.
and I click 'OK'.
From here, I enter the connection string of my locally hosted oracle database (localhost:1521/MY_DB.
When prompted for credentials, I select 'Database' and then enter the correct username/password to connect to my locally hosted oracle database.
Then I receive an error stating:
Unable to connect
We encountered an error while trying to connect.
Details: "An error happened while reading data from the provider: 'Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.'"
I've also tried the following method:
Models
-TabularProject (my project)
-Data Sources > New Data Source > ODBC
Then I choose my ODBC datasource for my locally hosted database (which seems to work fine for other apps) and I receive the following error:
Unable to connect
We encountered an error while trying to connect.
Details: "ODBC: ERROR [IM014] The specified DSN contains an architecture mismatch between the Driver (64-bit) and Application (32-bit)"
I have installed various Oracle Drivers including:
-64-bit ODAC: ODAC122010Xcopy_x64.zip
-64-bit instantclient basic: instantclient-basic-windows.x64-21.6.0.0.0dbru.zip
-64-bit instantclient odbc: instantclient-odbc-windows.x64-21.6.0.0.0dbru.zip
-64-bit instantclient sqlplus: instantclient-sqlplus-windows.x64-21.6.0.0.0dbru.zip
I have also tried these same steps for a remote hosted Oracle database (using both ezconnect string and a ODBC DSN) and even though the connections work just fine with other apps, it doesn't work with SSAS for some reason.
Any and all insight advice to get my SSAS tabular model connected to Oracle databases would be very much appreciated.
EDIT:
I have tried following a solution from this similar question and create a dsn, suffixed with _64, using only the 64-bit ODBC manager, yet I get the same results when trying to use that DSN with SSAS.
I have also tried the following steps, per Microsoft:
From https://learn.microsoft.com/en-us/sql/reporting-services/report-data/oracle-connection-type-ssrs?view=sql-server-ver16#64-bit-and-32-bit-drivers-for-power-bi-desktop:
2. Register ODP.NET Unmanaged Client to GAC:
C:\Oracle\odp.net\bin\4\OraProvCfg.exe /action:gac /providerpath:C:\Oracle\odp.net\bin\4\Oracle.DataAccess.dll
3. Add ODP.NET Unmanaged Client entries to machine.config:
C:\Oracle\odp.net\bin\4\OraProvCfg.exe /action:config /force /product:odp /frameworkversion:v4.0.30319 /providerpath:C:\Oracle\odp.net\bin\4\Oracle.DataAccess.dll
Yet, I still receive all errors shown above.
How can I run Oracle APEX application on Client PC which is connected remotely to Database server side PC through Oracle Client Service software.
Oracle XE 11.2g
Oracle APEX version 19
Client service sotfware version 21.1.
You wrote an application. When you run it, all you need is a web browser. There's the application URL in browser's address line. It looks like
http://your.server:8084/apex/f?p=120:1:3120653734023:::::
Client (person) needs this part of it (120 represents APP_ID):
http://your.server:8084/apex/f?p=120
Send it to the client" who will just have to click on it and - if you're in the same network - get application's log in window. If you also provided username and password, client will be able to run the application.
Therefore, you don't have to install any Oracle software on client's PC.
Hi everyone here,
I am pretty new to Oracle DB configurations as I have been using SAS and Microsoft SQL all this while.
What i want to do is to add Oracle DB to ODBC(64-bit) in a new server.
This is the scenario:
Server A:- Existing Application server that has Oracle configured in ODBC(64-bit)(Been using for the past 3 years, configured by other people).
Server DB:- The Database server
Server B:- Brand new server that i want to configure Oracle DB in ODBC(64-bit)(Brand new).
I copy every single details of the server information in Server A ODBC for the same Oracle DB and put it in Server B ODBC. I have both Server A and Server B remote connection side by side and do "Test Connection".
Server A can connect successfully. However, Server B is giving me this error:
SQLState=08004
This is my first time trying to configure for ODBC to Oracle DB. I have previously configured many Microsoft SQL DB without any issue. Do take note that i have not installed any Oracle driver or any necessary-tool needed for ODBC to link with Oracle as i do not know of any. Is there anything i have to install for this to work or any necessary settings need to be done before configuring it?
All this while for Microsoft SQL connection to ODBC, i just put in the DB credentials and voila.
Your help is very much appreciated.
My organisation wants to setup DB2 for our .Net application that links/uses the database setup on a remote desktop with a fixed IP address. Now, I'm trying to setup this DB2 databse using DB2 Express-C and IBM Data Studio and it is unable to connect to the database through the Java connection.
How do I know this? I tried performing a normal SQL operation using a DB2 command window and it worked.
If I try to do the same thing with Data Studio or command line processor, it doesn't work: always throws a 'user ID revoked' error.
I tried reconfiguring environment variables to JDBC4 driver, using it from an administrator account, but nothing works.
Question - How do I make this work properly? is there any guide or tutorial anyone can share to setup db2 express c properly.
Recently we have developed an application which connects to oracle database for fetching records. For fetching records, we are using OLEDB for Oracle. Application runs fine on my machine by connectng properly with Oracle ,since i have oracle client installed on my machine. Now i tried to test application on another machine, which doesnot have any oracle instance/Client installed on his machine. Application fails to connect to oracle central DB Server. Is it necessary for users to install oracle client on their machine before the application communicates with Oracle.
Here is Connection string
connectionString="Provider=msdaora;Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=XYZ)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=abc.com)));Persist Security Info=False;User Id=mahens; Password=XXXXXXXXX" providerName="System.Data.SQLOLEDB"/>
The above code is for OLEDB for oracle. Is there any thing i required to install for connecting to central Oracle DB server from my windows application(.NET application installed on local machine).
If we try to use ODP.NET dll and include those dll's along within BIN directory,will that work?..Can any1 tell me a way wherein user need not install any oracle Client on their machine and communicate to server.
-Mahender
I believe you always need the oracle client installed as everything in .net ultimately uses ODP.NET. However, you can use the Oracle Instant Client to make your users' setup process easier.
