i tried to connect to Oracle using Sql server migration assistant for oracle(SSMA for oracle).
and specified parameters like this
provider: Oracle Client Provider
mode: standard mode
and connection info(servername, port ...)
but i got a error message
"Unable to find specified provider.
Compatible Oracle Data Access Connectivity libraries were not found on the machine. You can install them from Oracle product media or download it from Oracle web site."
so i installed Oracle Data Access Components(ODAC),
http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html
but same error message appeared.
what is Compatible Oracle Data Access Connectivity library?
I faced the same problem, Oracle Data Access Components (ODAC) are required for applications to connect to the database, to use "SSMA" you need to install Oracle instant client,
1) Download http://www.oracle.com/technetwork/database/database-technologies/instant-client/overview/index.html
2) Unzip, then add the folder to the path, open control panel > system > Advanced > Environment Vriables > choose Path and Edit it to add a new entry with your folder.
3) Connect with the 'system' user (user id = system)

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.
I'm new to OBIEE. I have version 12.2.1.4 installed on a Linux server. I installed the client tools on my Windows PC. Using the Administration tool I created a simple RPD which uses only two tables. For this I had to first create an ODBC DSN to connect to my DB/2 database.
Next, I uploaded the RPD to the OBIEE server using the datamodel cli tool. When I go to the http://hostname:9502/analytics page and select to create a new analysis, it shows me the name of the repository and the two tables. I selected a couple of columns and clicked on the Results tab.
At this point, I get an error message: ODBC error state: IM002 code: 0 message: [DataDirect][ODBC lib] Data source name not found and no default driver specified
I had used the em console to create a JNDI connection to DB/2. But, from the message it seems that it is trying to use the ODBC connection that was used when creating the RPD on my PC.
How do I change the connection that the server is using?
The server needs to be able to reach the data source. EM JNDI connections have nothing to do with it, but rather the server (server OS - not the application) has to reach the source.
You need to update your ODBC settings on the Linux server: https://support.oracle.com/epmos/faces/DocContentDisplay?id=2570997.1
I'm trying to install Informatica 10.1 on OCI and thereby connecting it to ADW for the INFA users access.
I've successfully established connectivity with ADW through sqlplus using the wallet keys. However, during the Informatica installation I'm not able to connect to the ADW database. Below is an excerpt of the connection that is being tried by the installer.
Configure the database for the domain configuration repository:
Database type:
* 1->Oracle
2->SQLServer
3->DB2
4->Sybase
(Default: 1):
Database user ID: (default :- dbadmin) :
User password: (default :- ) :
Configure the database connection
1->JDBC URL
* 2->Custom JDBC Connection String
(Default: 2):
I'm wary on the custom JDBC Connection String that is being asked. Usually the default string is something like this:
jdbc:informatica:oracle://somestringfromtnsnames.oraclecloud.com:1521;ServiceName=somestringfromtnsnames.adb.oraclecloud.com
But in this case I'm connecting to ADW via wallet & ideally the wallet information should be provided. I just am not sure how. I've prepared a string in accordance to the same which I thought was correct, but it doesn't work.
jdbc:informatica:oracle:#tnsnamesalias?TNS_ADMIN=/path/to/my/wallet/store
Has anyone got any idea on this? Any pointers would be helpful.
From what I understand, the DataDirect JDBC drivers used by Informatica do not support Oracle's encryption, which is required to access ADW. It appears that you can use Oracle Client on an existing Informatica installation to add ADW as a target, but not using JDBC or ODBC. There appear to be limitations to this in terms of metadata access, and some import steps will need to be completed manually.
In spite of what it implies in "Autonomous Database 3rd Party Tools and Applications" for Informatica, the only way to complete a new installation - according to the steps in Appendix A of the doc - is to first disable the SQL*Net encryption. This requires a level of access to the Oracle configuration files and processes that does not exist for Autonomous Database services (i.e. access to sqlnet.ora and lsnrctl). It only exists if you are running your own VM host (Infrastructure as a Service) with a stand-alone installation of Oracle Database that you fully control.
I have a database Connection established in odbcad and Microsoft Access (aswell as working in Excel) via ODBC and want to also get it working in Oracle SQL developer.
It is a Windows SQL Server as far as i know and I have tried several Settings, of which None works. I have also installed Driver for ODBC. I would like to Import Settings into SQL developer as applied in MS Access, is there any possibility?
No, SQL Developer is a Java application and uses a JDBC driver.
But if you look at the odbc properties for your connection, those should largely translate to what you need to define a basic connection.
Oracle:
Server name or IP address of the DB, port # for the listener, and the name of the SID or Service, plus a valid username and password is all you need to connect to Oracle.
What error do you get when you try to connect?
Show us what you're trying.
Update:
You're trying to connect to SQL Server but you're getting"
Native SSPI library not loaded
You're trying to use OS Authentication for your connection. For this to work with the jTDS driver, you need to copy a DLL file named ntlmauth.dll (which is for NT authentication) under the jtds-x.x.x-dist\x86\SSO\ or jtds-x.x.x-dist\x64\SSO\, to any directories in the PATH environment.
Please update your question such that's it's clear you're connecting to SQL Server and share the error message so others can find it.
I imagine this question is a duplicate of many previous iterations of the same challenge.
I am absolute beginner to oracle and thought of getting started with installing Oracle Sql developer.
Basically i downloaded the zip package and unzipped to program files and opened sqldeveloper.exe.
Then I chose New connection and then filled the connection name,username,password and others but when I test the connection I get the following error.
Status : Failure-Test failed: IO Error: The Network Adapter could not establish the connection
I'm looking to connect to local database for practicing queries.
How do I fix this, is there something else I should install?
Before downloading the Sql Developer, Download the Latest version of Oracle Database from here
1) Now run the Downloaded Oracle database and during installation, it will prompt to create a password for User named 'SYSTEM' .
In my case i have created the password as 'oracle'.
So my credentials for Oracle Database are
User Name: SYSTEM
Password : oracle
2) Now download the SQL Developer and extract it to a local folder.Once Extracted, click the sql developer application file --> Connections Tab --> New Connection (+ icon)-->
Connection Name: TestConn (give some random name)
Username: SYSTEM
Password: oracle (the password i have given during installation of oracle database)
Leave all the other default fields as they are .(see the screenshot below).
Click on test for testing the connection.
