I am very inexperienced and without appropriate training so apologies if I don't phrase this right or include enough information.
I am attempting to connect a SQL server (Accessed typically via Microsoft SQL Server Management Studio) to a data warehouse via Oracle SQL Developer. But I just can't get SQL developer to recognise the JTDS drivers to enable the SQL Connection. I have downloaded multiple versions of the driver (Jtds1.2.2 and Jtds1.3.1) and I have used the Tools/Preferences/Database/Third Party JDBC drivers tab to specify their location. But I never get a SQL connection option in the connection dialogue. There are no error messages produced, it just never seems to do anything.
The goal of my efforts is to be able to directly access the data warehouse from our SQL server.
I have watched numerous videos showing this process working and I can't work out what is going wrong. The Oracle website suggests that these drivers can be installed via the Check for Updates function but this doesn't do anything when I have attempted it.
The solution was to Copy the drivers into the same parent directory as the SQL developer. Previously I had tried copying it inside one of the sub folders and tried copying it outside of the directory. But as soon as I put it in the main SQL developer folder it worked.

I don't know how to describe the problems with the Oracle SQL developer program. I am new at this. The story is here;
I downloaded Oracle SQL Developer 22.2. And I started sqldeveloper.exe. Oracle SQL Developer is started but I am not doing anything in this program. Everything freezes. The Create database button is inactive. Press the... button and press .. but nothing changes.
My computer is a gaming computer and not old. The hardware is above the minimum requirements to install the program.
I tried resetting the windows factory settings...
I tried deleting and installing it.
I tried the old version of sqldevelepor.exe...
How can I solve this problem?
SQL Developer is a GUI tool we use to access (most usually) an Oracle database.
But, to do that, you need a database. According to what you said so far, there's none so - SQL Developer itself can't do much.
I'd suggest you to visit the same site (Oracle Technology Network, OTN) from which you downloaded SQL Developer, and this time download the database. Pick the Express Edition (XE) as it is easy to install and use. Along with the installation process, the setup will create the database for you (so you won't have to create it manually).
Then, once it is done, you should be able to use SQL Developer to connect to it. At first, you'll use SYSTEM or SYS users (pay attention to connect as SYSDBA in that case). Don't use these users for anything but administration purposes - create a new user (you can call it e.g. "berfin"), grant privileges to it (most usual are create session, create table, create view, create procedure) so that you could start working with it. In that schema (i.e. user) create your own tables, insert data, do whatever you planned to do).
I believe you should read some documentation first; OTN has it all. Start with the Concepts book, see short DBA (so that you'd be able to create your own user, etc.), have a look at SQL reference book (if you don't know SQL already). That should get you started. On the other hand, you could take shortcuts and check some YouTube videos/tutorials, ask here and there, Google for problems you meet but - in a long turn, if you really want to work with Oracle - read documentation.
tools --> preferences --> environment --> look and feel: windows (not oracle)
So I have successfully installed Oracle DB 19c and connected it to Oracle SQL Developer. I am able to create tables and run queries. Furthermore, I can connect to ADW with both python and SQL Developer and any changes that I commit are seen in all locations. I am trying to connect the ADW database to Power BI. I am running all this on a personal Windows 10 Pro laptop with plenty of SSD & RAM.
In a new window of Power BI I click Get Data and then Oracle Database followed by Connect. When I do this I get a pop up that says:
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.
I clock OK. Enter my Server as the TNS Name that I have used for my python and SQL Developer instances. In my ADW database, I have a table called TEST. It's a simple table with 1 column with the years 2015 through 2020 in it. Been using this to test to see if things are working. So I click on the DirectQuery and run the SQL statement SELECT * FROM TEST under the Advanced options menu and select OK. A sign in window pops up and I select the Database table and enter my correct ADW username and password. The same one that I can use to access this table from SQL Developer and then select Connect. When I do, I get this error:
Details: "The provider being used is deprecated: 'System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.'. Please visit https://go.microsoft.com/fwlink/p/?LinkID=272376 to install the official provider."
So I go to the website and download the ODAC122011_x64 file from Oracle and unzip it. When I double click the setup.exe file inside the directory I get a yes/no user control account menu and I select yes and then a command prompt window flashes very quickly and then nothing happens. I ran a super slow motion capture from my phone to capture what the command window showed and below is what I see:
Starting Oracle Universal Starter...
Checking monitor: must be configured to display at least 256 color Higher than 256 . Actual 4294967290 Passed
Preparing to launch Oracle Universal Installer from C:\Users\<my username>\AppData\Local\Temp\OraInstall2020 09:20_09-04 {???}
Please wait .._
It does nothing after this I have tried running the oui.exe file under the install subdirectory and get nothing and I have tried running the install.exe file in Oracle Universal Installer that I acquired when installing Oracle DB 19c and I get the following error when I target the install.exe file for installation:
OUI-10118:C/Users/{my username}/Downloads/ODAC122011_x64/Setup.exe is either a directory or a corrupt file. Specify a valid filename.
This is a file that I just directly downloaded from Oracle's website and unzipped to a directory with no spaces in the directory location. I have the latest version of Java installed (JDK 15).
I am not sure the proper work around here. Why can't I get my Power BI to connect to my Oracle ADW table using the methods described in this article. Those are the instructions that I used. It appears that I need this ODAC application but I don't understand why it won't install.
Can anyone help me resolve this issue? Thanks!
Edit: I am using 64-bit on each application.
Update: Still having issues. I checked the log and this is what I am seeing:
Using paramFile:
C:\Oracle\Oracle_PowerBI_ODAC\ODAC122011_x64\install\oraparam.ini

the client version need not match the server version, Removing all other versions, and making sure that I had the x64 version,
You need the latest ODP.net library to use Oracle. Please download it here:http://www.oracle.com/technetwork/topics/dotnet/utilsoft-086879.html
I figured out the solution after reviewing this post. Apparently having over 2TB of free space on a hard drive causes this problem. You have to go into command prompt and create a temporary file to get your free space under 2TBs using something like this:
fsutil file createnew temp_1TB_file 1200000000000
Run the setup.exe again and then delete the temp file after.
Update: After doing all this I still was running into the same issues in Power BI. Then I read the troubleshooting notes from this page more closely and realized that I might have found the problem when it said:
If you downloaded Power BI Desktop from the Microsoft Store, you might be unable to connect to Oracle databases because of an Oracle driver issue.
I uninstalled the PowerBI Desktop that I had installed from Microsoft Store and installed it from the download from its website and tried connecting to Oracle ADW again through PowerBI and IT WORKED!!! So much troubleshooting but it finally works!
Want to use an Oracle-ODBC connection in Visual Studio 2017/ SSIS as it's much faster than OLE DB during tests.
Problem:
I follow Oracle's steps to the letter.
Install instant client (v18, also tried v12).
Download/ extract ODBC download in same library. Run odbc_install.exe.
See the Driver in 'ODBC Data Sources/ Admin' in Windows 10.
Add new User Data Source. TNS Service names pull up fine. Test
Connection (User/ Pass) -- it works!! The Connection works!!
I tried this with 64 bit in Oracle, their instant client v18.3 or 12.2 both. All works in Window's "Oracle Source Administrator" via test connections.
I tried this with 32 bit downloads as well. All is good.
Now, open Visual Studio. First tried 64 bit (my Windows OS is 64 bit, but Visual Studio Data Tools is only 32 bit). Had a hunch it wouldn't work.
Error message "system architecture and client is not the same" or such. Gotcha.
Tried the 32 bit Oracle ODBC driver (User Source). I keep getting the same message (tried 18_3 and 12_2 versions).
Now .... SQLORA32.dll is in the very file path it named. It's right there! Why can't it be found? The test connection in ODBC Source Admin works! What is going on here?
And I'm unsure if I have to "register" something via the command line, I had to do that once before, maybe it was an unrelated issue.
To boot, when I tried a 3rd party "Devart Oracle ODBC connector" -- it's a simple 5-second install wizard that works flawlessly instantly. Problem is it's a 30-day trial and costs $150 at least. How can I can get an Oracle-created ODBC connector (Oracle being world-renowned for janky-azz products) to actually work?
Devart, and probably Attunity Oracle ODBC: 5 second installs
Oracle's own: Harder to install than breaking into Fort Knox/ learning Mandarin Chinese. Please advise.
I am answering my own question.
Unfortunately some of us ETL/ BI guys need to go so wide on problems that there's no time to figure out every little detail/ glitch of Oracle's ... whatever they're doing now.
But here's a fix. In Visual Studio 2017/ Data Tools/ the SSIS IDE .... if you want an Oracle ODBC connection (Faster than OLE Db for some reason) --- when you're setting it up, instead of selecting a NAMED "user or system data source" that you created in ODBC Source Administrator, simply using the "Builder" option (to the left of Use Connection String) for a connection string. It does the exact same steps as the ODBC Source Admin, but within Visual Studio. I don't know what the difference is here, but some wizardry/// who knows what is different, and the connection somehow, suddenly, for some reason, works.
do I need to install oracle db before using sql developer? I just install Oracle Sql Developer and I'm getting a message box saying: "Enter the full pathname for java.exe".
It looks to me like Oracle Sql developer is like the Sql Server Management Studio, which works on top of the Sql Server.
The first thing you'll need is a JDK installation. The message Enter "the full pathname for java.exe" refers to that. You'll need to provide the path of the 'bin' folder in the installed JDK
After that, yes you'll need a database installed on your PC or a remotely accessible DB will also suffice. SQL developer provides just a UI for running your SQL, PL/SQL queries. Its an IDE, not a database
Oracle Database includes SQL Developer but SQL Developer doesn't include a database. You have a few options for getting up and running quickly.
http://www.thatjeffsmith.com/archive/2012/12/i-have-oracle-sql-developer-installed-now-what/
Technically you can use SQL Developer without any database. It has an offline editor, data modeling component, and other features which do not require a database connection.
I have installed Cognos BI 8.3 on my machine, which has a Windows 7 OS 64-bit. In IBM's supported environment list for Cognos 8.3, Windows 7 is not listed. On top of that, it says the product will only integrate with 32-bit 3rd party libraries. So, you can already see that I'm already starting on a bad foot. But anyways, this is the machine I have and that is the software I got, so I decided to see if they would work together..
I installed Oracle 10g Express database also in my machine and Apache 2.2 server. Up to there no problems.
Before moving further, I copied ojdbc14.jar to cognos/.../webapps/p2pd/WEB-INF/lib and added the Oracle database in Cognos Configuration. Tested, passed.
With the database started, the Apache server started, and Cognos started, I was successfully able to start Cognos Connection on the computer. So, it looks like the OS is not an issue.
(You can see everything I did by following the steps on this site, which since two days ago seems to be down but I'm thinking will eventually come back up)
Then I decided to try the samples, so I tried to create a data source connection from Cognos to the Oracle database. So, in the admin config console (i.e. Administer Cognos Contents > Configuration), I decided to create a new Oracle data source. I put the credentials, but BAM.. testing fails.
Fail Message:
QE-DEF-0285 The logon failed.
QE-DEF-0323 The DSN(ODBC)/ServiceName is invalid. Either the DSN is missing or the host is inaccessible.
RQP-DEF-0068 Unable to connect to at least one database during a multi-database attach to 1 database(s) in:

UDA-SQL-0532 Data Source is not accessible: "XE".
ORA-12154: TNS:could not resolve the connect identifier specified
RSV-SRV-0042 Trace back:

From what I have researched, it could be a number of things, but nothing seems to work. Here is what I tried:
Adding ODBC driver. Added the Oracle XE driver, even making sure it was done in the 32-bit ODBC manager (i.e. Windows\SysWOW64\odbcad32.exe). That didn't work.
Added ORACLE_HOME, LD_LIBRARY_PATH, and TNS_ADMIN to my environment variables.
tnsping'ed the XE database and it the ping returned ok.
There are no tnsnames.ora duplicates in the computer.
I tried and I am able to connect to the database via sqlplus. Did I mention that Cognos Config database test also passed?
Installed Oracle XE client. But didn't do much with it because the Oracle server is installed in the computer and also has a client component.
Has anyone come across this problem? I haven't been able to diagnose the problem or make even the slight progress for days. If you would like me to provide more information on any of the solutions I tried, please do ask. If you have a potential solution or, even better, if you have been able to solve this problem before, please let me know how!
Thanks!
One thing to keep in mind : certain portions of Cognos BI are implemented via Java and other portions are implemented via native C++ processes (the BI Bus processes)
Cognos connects to the content store database from the Java process using JDBC.
The BI Bus processes will connect to Oracle using a native oracle client.
So based on your description, I'd say that the problem area is in the native oracle client configuration (or the Cognos service's perspective of it).
You mentioned adding the ORACLE_HOME, LD_LIBRARY_PATH, and TNS_ADMIN environment variables in windows, and the fact that Oracle Utilities like SQLPlus and TNSPing are working for you.
When you added the environment variables, did you add them to the SYSTEM area for environment variables or the User area...?
If you're running Cognos as a service, its going to be a child process of SERVICES.EXE, which is run as system (this process is also not restarted unless you reboot the machine).
I'd try this :
make sure the above environment variables are defined for the SYSTEM user (in the system area, not the user area)
once you've done this, reboot the machine
See if you can create the database connection now.
If that doesn't work, I'd suggest doing a "run as" of SQLPlus or TNSPING as the SYSTEM user (and see if that works).
In order to use oracle as data source, you must install 32 bit client.
64 bit client will not work.
So if you installed oracle express 64 bit, and you don't want to uninstall it,
you can just install additional 32 bit client, and make sure to set it as your default home.
