I want use PL/SQL Developer
first my oracle directory
C:\oracle\product\10.2.0\client_1\BIN
I use windows10 and environment variable setting
ORACLE_HOME C:\oracle\product\10.2.0\client_1
Path C:\oracle\product\10.2.0\client_1\BIN
but execute Initialization error.

download oracle instant client (64 bits for latest version of PL/SQL; 32 bits for old version)
extract to a folder. for example: c:\oracle\instantclient
open PL/SQL developer--> Configure--> Preferences --> Oracle Connection
under OCI library, keyin OCI.DLL file path in the text box: c:\oracle\instantclient\oci.dll
click OK and restart PL/SQL
I meet the same error on my new windows 10 computer. At last i found that i missed the Microsoft Visual Studio 2013 Redistributable. After i install it, the error gone.
I was getting below error while connecting to database from PL/SQL developer (in windows10 64 bit).
Initialization error
Could not initialize
"C:\app<username>\product\12.2.0\dbhome_1\bin\oci.dll"
Make sure you have the 32 bits Oracle Client installed.
OracleHomeKey:
OracleHomeDir: C:\app\<username>\product\12.2.0\dbhome_1
Found: oci.dll
Using: C:\app\<username>\product\12.2.0\dbhome_1\bin\oci.dll
LoadLibrary(C:\app\<username>\product\12.2.0\dbhome_1\bin\oci.dll)
return 0
To resolve this issue, refer to the below documentation provided by Oracle to install the Oracle Instant Client. If your windows is 64 bit, then download the 32 bit Oracle Instant Client from below link -
Oracle guide
Link to download the Oracle Instant Client - (Download the BASIC and SDK and SQL*Plus Package)
Take all the above three packages in one directory and extract the same and add the path of extracted directory in system environment variable PATH and OCI_LIB32.
If OCI_LIB32 is not present then create the same.
Try to connect to database from PLSQL developer, if you getting error as 'ORACLE initialization or shutdown in progress' then go through the below link
Good Luck :)
Check Environment Variables %PATH%
I had the similar problem and these steps did helped me
steps:
Download oracle instant client (64 bits for latest version of PL/SQL; 32 bits for old version)
Extract to a folder. for example: c:\oracle\instantclient
Open PL/SQL developer--> Configure-->Preferences--> Oracle Connection
Under OCI library, keyin OCI.DLL file path in the text box: c:\oracle\instantclient\oci.dll
Click OK and restart PL/SQL
done
Most of the cases this happens
If you dont have any oracle client
In this case, you can download instant client and put it in C drive, then copy the path of the oci.dll file path and put it in the OCI library text field in the PL SQL Dev config option
If you have multiple oracle home
If you have multiple homes reflecting, then check the correct oracle home from the Oracle Home drop down in PLSQL Dev config option.
Attached the image of the config screen for easy reference.
Download oracle client after that use PL/SQL to connect

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 number of files bootstrapped for the jre is 0.
The number of files bootstrapped for the oui is 0.
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!
I get this error when I launch Toad for Oracle.
No valid Oracle clients found. You need at least one 64-bit client properly configured.
This has been happening since I upgraded the Oracle Client to Oracle 12c from 11g.
Here is what I have done so far to try to resolve it based on internet research:
I checked the path variable, it's currently set to C:\xyz\Oracle\ora12.1\client_2\bin, and there is an Oracle installation at this path.
I checked the TNS_ADMIN variable, it is currently set to C:\xyz\Oracle\ora12.1\client_2\network\admin. This also appears to be valid and correct, there is a tnsnames.ora file under this path.
SQL Plus works without issues, and Oracle SQL Developer also works without issues.
Is there anything else I can try to resolve this issue? Unfortunately, uninstalling and reinstalling Toad is not an option at this point as I do not have access to a new setup.
The issue is due to not having the Oracle Database installed on your computer.
You can download the database here: https://www.oracle.com/database/technologies/appdev/xe.html
Once the zip file is downloaded and extracted, run setup.exe. Once that is complete, the Oracle DB will be installed on your machine and the error will no longer appear.
With TOAD you need to have oracle client installed on your computer and you must configure the related TNSNAMES.ORA to connect to the server.
If you use SQLDeveloper you can do without oracle client installation.
I have a computer which acts as a server for Oracle database 11g Enterprise. I want to use another computer, a PC that is running Windows XP SP3, as a client of this server.
So I decided to install Oracle Instant Client 11.2.0.4.0 on client PC. I downloaded zipped file from Oracle OTN and extract it into folder like c:\oracle\instantclient11.2.0.4.0. Then I added this path to the system path variable, and created another system variable called TNS_ADMIN for variable name with the same path for Oracle Instant Client, c:\oracle\instantclient11.2.0.4.0 .
Finally I copied the tnsnames.ora from server pc.
So I want to try to run the sqlplus from cmd.exe but the error is :
The procedure entry point OCIBindByName2 could not be located in the dynamic link library OCI.dll .
Can anybody help me?
Have you set ORACLE_HOME to c:\oracle\instantclient11.2.0.4.0 too?
It should be fixed in 11.2 though as descibed in 343666.1 :
This dependence on ORACLE_HOME issue has been resolved in Bug: 5532439
OCI.DLL MUST APPROPRIATELY CALL SETDLLDIRECTORY. The fix is to call
SetDllDirectory based on the location of where the OCI.DLL is located.
Workaround for this issue:
Do an Instant Client Installation, for example into, C:\Oracle\EZClient102
Set the ORACLE_HOME environment variable to the ORACLE_HOME of the Instant Client.
set ORACLE_HOME=C:\Oracle\EZClient102
Then the Instant Client DLL's should be loaded from
C:\Oracle\EZClient102\bin
I am getting error "[Oracle][ODBC][Ora] ORA- 12154: TNS: could not resolve the connect identifier specified." when I am trying to connect to remote database using 3rd party software. I am using Windows 7 64 OS and Oracle 10g 32 bit client.
I have tried all the solution given on stackoverflow, but unable to solve the issue on the following links.
Ora 12154 error
ODP.NET ORA-12154 TNS error only when run as service

Update
As per the link below from Oracle one needs to install Oracle 10.2.0.5 patch to run on Windows 7. Please let me know where to find this patch as it is not available to download free from Oracle's website.
http://docs.oracle.com/cd/B19306_01/relnotes.102/b14264/toc.htm
Update 2:
I found another link which says that I need to have the same version of ODBC manager as that of the Oracle Client. Hence now this sums up to that I need the version 10.0.2.5 of both Oracle client and of ODBC manager. But what I found is that there are 2 different versions of ODBC manager in my computer. One is at C:\Windows\System32 and other at C:\Windows\SysWOW64. After some googling I came to know that WOW (Windows on Windows) is used for running 32 bit applications in 64 bit Windows OS. When I test the connection to database through ODBC manager in System32 folder, it gets connected but when I try to connect to the same database through an application I get the following error:
[Microsoft][ODBC Driver Manager]Driver's SQLAllocHandle on SQL_HANDLE_ENV failed.
Could it be possible that the applications on my system try to connect to the Database through the ODBC manager which is not working properly (inside SysWOW64 folder)?
Please let me know how to solve this and if there is some information that I may be missing to provide.

I can't seem to figure out how to install the Oracle client on Windows Server 2008.
I downloaded x64 version (the first file on the list) here. There are installation instructions on the bottom of that page:
Step 2 ("instantclient")
Which executable should I run?
The instantclient works only by defining the folder in the windows PATH environment variable. But you can "install" manually to create some keys in the Windows registry. How?
1) Download instantclient (http://www.oracle.com/technetwork/topics/winsoft-085727.html)
2) Unzip the ZIP file (eg c:\oracle\instantclient).
3) Include the above path in the PATH.
4) Create the registry key:
Windows 32bit: [HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]
Windows 64bit: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE]
5) In the above registry key, create a sub-key starts with "KEY_" followed by the name of the installation you want:
Windows 32bit: [HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_INSTANTCLIENT]
Windows 64bit: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE\KEY_INSTANTCLIENT]
6) Now create at least three string values in the above key:
NLS_LANG = BRAZILIAN PORTUGUESE_BRAZIL.WE8MSWIN1252 (complete list here: http://docs.oracle.com/cd/B19306_01/install.102/b14317/gblsupp.htm)
ORACLE_HOME = c:\oracle\instantclient (the same folder in PATH)
ORACLE_HOME_NAME = MY_INSTANTCLIENT (choose any name)
For those who use Quest SQL Navigator or Quest Toad for Oracle will see that it works. Displays the message "Home is valid.":
The registry keys are now displayed for selecting the oracle client:
I was able to setup Oracle Instant Client (Basic) 11g2 and Oracle ODBC (32bit) drivers on my 32bit Windows 7 PC. Note: you'll need a 'tnsnames.ora' file because it doesn't come with one. You can Google examples and copy/paste into a text file, change the parameters for your environment.
Setting up Oracle Instant Client-Basic 11g2 (Win7 32-bit)
(I think there's another step or two if your using 64-bit)
Oracle Instant Client
Unzip Oracle Instant Client - Basic
Put contents in folder like "C:\instantclient"
Edit PATH evironment variable, add path to Instant Client folder to the Variable Value.
Add new Variable called "TNS_ADMIN" point to same folder as Instant Client.
I had to create a "tnsnames.ora" file because it doesn't come with one. Put it in same folder as the client.
reboot or use Task Manager to kill "explorer.exe" and restart it to refresh the PATH environment variables.
ODBC Drivers
Unzip ODBC drivers
Copy all files into same folder as client "C:\instantclient"
Use command prompt to run "odbc_install.exe" (should say it was successful)
Note: The "un-documented" things that were hanging me up where...
- All files (Client and Drivers) needed to be in the same folder (nothing in sub-folders).
- Running the ODBC driver from the command prompt will allow you to see if it installs successfully. Double-clicking the installer just flashed a box on the screen, no idea it was failing because no error dialog.
After you've done this you should be able to setup a new DSN Data Source using the Oracle ODBC driver.
-Hope this helps someone else.
The directions state:
Download the appropriate Instant Client packages for your platform. All installations REQUIRE the Basic package.
Unzip the packages into a single directory such as "instantclient".
Set the library loading path in your environment to the directory in Step 2 ("instantclient"). On many UNIX platforms, LD_LIBRARY_PATH is the appropriate environment variable. On Windows, PATH should be used.
Start your application and enjoy.
Suggest extracting/unzipping into a new directory. They've suggested instantclient, but you can name the directory anything you like. Name it C:\OracleInstantClient\ if you choose.
Then in Step 3, open a Windows Command Prompt. Type:
PATH C:\OracleInstantClient; %PATH%`
That's all there is to it!
If you want to use SQL Server Management Studio, you want to install the full Oracle client, not the Instant Client. The full Oracle client is on the same download page as the Oracle database. Assuming that you are installing on a 64-bit version of Windows, I expect you want the "Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64)" download. This is several hundred MB rather than a couple of MB for the Instant Client.
Try SQLDeveloper - there is a migration workbench there
