I'm trying to start working through Tom Kyte's book, "Expert Oracle Database Architecture" and have run into a snag. Tom recommends creating a custom login.sql script and briefly mentions setting the SQLPATH environment variable.
I've been following the instructions found here: http://docs.oracle.com/cd/B28359_01/server.111/b31189/ch2.htm#i1133354
I've searched for the SQLPATH and HOME0 keys, and for the ORACLE_HOME\DBS value, but it doesn't seem to exist in the Registry. I have Oracle 11.2 Express, Windows 8, and my Oracle instance name is the default, XE. In the Registry, I see
HKEY_LOCAL_MACHINE
SOFTWARE
ORACLE
KEY_XE
...
ORACLE_HOME (value: C:\oraclexe\app\oracle\product\11.2.0\server)
ORACLE_HOME_KEY
ORACLE_HOME_NAME
...
ODE
...
OLEDB
...
ODP.NET
2.112.2.0\
4.112.2.0\
OracleMTSRecoveryService
Protid_0
Setup
All Versions
1\
Current Version\
Is it possible that the SQLPATH variable is no longer created by default, and that I need to just create a new one? If so, exactly where should it exist? If not, then what?
SQLPATH is a Windows system-or user environment variable not found under KEY_XE.
You can set the SQLPATH like this: Right-click on "Computer" -> Properties -> Advanced Settings - Environment
me#XE>host set SQLPATH
SQLPATH=c:\projects\oracle\sqlplus
-- verification
me#XE>#[%SQLPATH%]
SP2-0310: unable to open files "[c:\projects\oracle\sqlplus].sql

I am using Windows 10 pro x64, Oracle database 21c Express edition, Oracle SQL Developer 22.2.1 . How to set ORACLE_HOME correct?
I know this my setting was wrong (because sqlplus.exe cannot run/open with this system variable, I tried)
Is ORACLE_HOME
C:\app\Administrator\product\21c
C:\app\Administrator\product\21c\dbhomeXE
C:\app\Administrator\product\21c\homes
C:\app\Administrator\product\21c\homes\OraDB21Home1
?
Please guide me set ORACLE_HOME correctly!
On Windows you don't need to explicitly set an Oracle Home because we can work it out from the registry and the PATH.
But if you want to set an ORACLE_HOME its the parent folder of the 'bin' directory. Thus if sqlplus was found in C:\app\Administrator\product\21c\homes\OraDB21Home1\bin then your ORACLE_HOME would be C:\app\Administrator\product\21c\homes\OraDB21Home1
If you're running multiple versions/installations of Oracle (as I do), I'll often create a little batch file for each version,eg
sql19.cmd
=========
set ORACLE_SID=db19
set ORACLE_HOME=C:\oracle\product\19
set PATH=C:\oracle\product\19\bin;%PATH%
sqlplus scott/tiger#db19_pdb1
sql21.cmd
=========
set ORACLE_SID=db21
set ORACLE_HOME=C:\oracle\product\21
set PATH=C:\oracle\product\21\bin;%PATH%
sqlplus scott/tiger#db21_pdb1
and so on
I had 11g previously installed and now I have installed 12c. Have not uninstalled 11g.
The environment variable 'path' is set to 'bin' of 12c and oracle home is pointing to home i.e '11.2.0\server', of 11g.
It works but I want the Oracle_Home variable to be set to home of 12c. I do not find the path to server of 12c even after much research.
What is the path to 'home' of 12c?
You said,
"The environment variable 'path' is set to 'bin' of 12c"
It should be a path that looks something like
C:\app\oracle_account\product\12.1.0\somefolder\bin in windows
or
\u01\app\oracle\12.1.0\somefolder\bin in Unix/Linux
So, your Oracle 12c home should be
C:\app\oracle_account\product\12.1.0\somefolder or
\u01\app\oracle\12.1.0\somefolder\
Now, in windows, check the registry entry ( regedit )
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_HOME_NAME
It should be set to the new oracle home discussed above otherwise change it or go to environment variables and set the ORACLE_HOME value.
Now, your PATH can be set using set PATH=%ORACLE_HOME%\bin;%PATH% to point to the correct bin directory.
For Unix, Linux you could export them correctly in the environment which you use to connect to the database.
export ORACLE_HOME='\u01\app\oracle\12.1.0\somefolder'
I installed both the 32 and 64-bit Oracle 11g drivers. I search my PC looking for files with the name "tnsnames.ora" and found 3 in the following locations:
1. C:\Oracle\product\11203_32bit\CLIENT_1\NETWORK\ADMIN
2. C:\Oracle\product\11203_64bit\CLIENT_1\NETWORK\ADMIN
3. C:\Windows\TNS
The existence of the 3rd location of the tnsnames.ora file surprises me.
I have the following Oracle clients installed on my PC:
"C:\Program Files (x86)\Quest Software\Toad for Oracle 11.6\Toad.exe"
"C:\Program Files\Devart\dbForge Studio Express for Oracle\dbforgeoracle.exe"
Based on the location of each program (Program Files (x86) vs. c:\Program Files), This suggests to me that the Toad, a 32 bit program, should use the 32 bit driver and dbForge should use the 64 bit driver.
dbForge seems to use either the tnsnames.ora file in either location #2 or #3. I know this by systematically renaming all but one of the tns files and then checking to see if the connection names read from the file are available when trying to create a new connection from with the app.
However, TOAD seems to only recognize the tnsnames.ora file in location #3 and it did not recognize the tnsnames.ora file in location 2 at all! (Being that it was a 32 bit program, I did not expect it to recognize the tns file in location 2 and that was the case). TO summarize the TOAD test for the sake of hopeful clarity, TOAD only recognized the tns file in location 3.
Other colleagues do not have a tns file in location 3 on their machines. I'm not sure why I do. When I run Toad, it shows the following 2 Home, with the 32 bit Home as being the active one.
OraClient11g_home1 (11.2.0.3)
ORACLE_HOME:C:\app\C39293\product\11.2.0\client_1

Q1: Is OraClient11g_home1 my 64 bit home or do I have two Oracle clients installed?
Q2: Why doesn't 32 bit TOAD use the tns in location #1 instead of only using the one in location #3?
Q3: If I leave on the tns file in location 3, both dbForge and TOAD work but I'd like to know why so I can accurately understand how to move tns info from one machine to another.
According Oracle these locations are searched for tnsnames.ora, resp. sqlnet.ora and ldap.ora:
Oracle Net files in present working directory (PWD/CWD)
TNS_ADMIN defined sessionally or by user-defined script
TNS_ADMIN defined as a global environment variable
TNS_ADMIN defined in the registry
Oracle Net files in %ORACLE_HOME/network|net80\admin (Oracle default location)
However, I am not sure whether each application/driver follows this list. I got this list from Oracle Document 111942.1 referring to Oracle 9i, so it might be outdated.
In Database Net Services Administrator's Guide the order is
TNS_ADMIN defined by environment variable
TNS_ADMIN defined in the registry (if TNS_ADMIN environment variable is not present)
%ORACLE_HOME%/network/admin directory (if TNS_ADMIN environment variable is not present)
I would recommend to define an environment variable for TNS_ADMIN and use only one tnsnames.ora file. In order to be on the safe side, check also your registry values.
If your files are not located in %ORACLE_HOME%\network\admin, I recommend to create a symbolic link for it - just to be on the very safe side, e.g. mklink /d %ORACLE_HOME%\network\admin c:\Oracle\common\settings\admin
Another note, you don't have to "play" with your tnsnames.ora file. With Process Monitor from Microsoft Sysinternals you can monitor each file access, i.e. the filter would be Path contains tnsnames
Update
When I run a test on my machine I get following order:
Environment variable TNS_ADMIN
Registry Key HKEY_CURRENT_USER\SOFTWARE\ORACLE\KEY_{Oracle_Home_Name}\TNS_ADMIN
Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_{Oracle_Home_Name}\TNS_ADMIN, resp. HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE\KEY_{Oracle_Home_Name}\TNS_ADMIN
-> Only if TNS_ADMIN Environment variable is not set.
%ORACLE_HOME%\network\admin
Current directory (which can be different to directory where your application is located)
Folder where your application is located
Update 2
Obviously there is no fix search, it varies for different providers/drivers. Maybe it also depends on the Oracle version.
For example, the Oracle HTTP Server reads TNS_ADMIN setting from opmn.xml config file.
Another example, for ODP.NET Managed Driver (Oracle.ManagedDataAccess) beta version, I found this order at Oracle Managed and TNS Names :
data source alias in the 'dataSources' section under <oracle.manageddataaccess.client> section in the .NET config file (i.e. machine.config, web.config, user.config).
data source alias in the tnsnames.ora file at the location specified by TNS_ADMIN in the .NET config file.
data source alias in the tnsnames.ora file present in the same directory as the .exe.
data source alias in the tnsnames.ora file present at %TNS_ADMIN%
(where %TNS_ADMIN% is an environment variable setting).
data source alias in the tnsnames.ora file present at %ORACLE_HOME%\network\admin
(where %ORACLE_HOME% is an environment variable setting).
In official documentation (12c Release 4 (12.1.0.2.4)) it says:
data source alias in the dataSources section under <oracle.manageddataaccess.client> section in the .NET config file (i.e. machine.config, web.config, user.config).
data source alias in the tnsnames.ora file at the location specified by TNS_ADMIN in the .NET config file. Locations can consist of either absolute or relative directory paths.
data source alias in the tnsnames.ora file present in the same directory as the .exe.
However, based on some tests I made with ODP.NET Managed Driver (4.121.2.0) it takes %ORACLE_HOME%\network\admin and TNS_ADMIN Environment variable into account. Locks like the documentation is not 100% correct.
Just based on your paths you have two installed clients as you suspect (Toad and dbforge are tools, not clients so your terminology is a bit off). One 32-bit, the other 64-bit. It appears that Toad is 32-bit based on its installation path, but execute it and go to Help|Support Bundle. You'll see the top header will be "APPLICATION INFORMATION (32-bit)" or "APPLICATION INFORMATION (64-bit)" just to confirm. Toad 11.6 was the first to introduce a 64-bit version.
Toad will only see the Oracle client that is for the same platform as it. So your 64-bit client is irrelevant for Toad's sake. The C:\Windows\TNS appears to be a folder used for TNS_ADMIN folder given its odd location and the fact that Toad sees it. At command prompt execute SET TNS_ADMIN and see if it reports "TNS_ADMIN=C:\Windows\TNS" If it does, then all Tools should be using that tnsnames.ora. That's a global override if you will that points to the folder containing your net configuration files. If you don't have TNS_ADMIN set as an environment variable then look for it in your Oracle root registry: HKEY_LOCAL_MACHINE\Software\Oracle.
If you use a common set of connections for all of your tools I'd delete all of your tnsnames.ora files. I'd also relocate that C:\Windows\TNS folder to somewhere more appropriate like C:\Oracle\Admin and create your tnsnames.ora, sqlnet.ora, and ldap.ora (if applicable) there. Create a TNS_ADMIN environment variable pointing to that location.
In case you are using Visual Studio v2017 here is tnsNames File:
32 bits installation:
c:\program files (x86)\oracle developer tools for
vs2017\network\admin\tnsnames.ora
64 bits installation:
c:\program files\oracle developer tools for
vs2017\network\admin\tnsnames.ora
I have an OracleXE 11g instance on a remote server machine. Some developers who have Russian Windows 7 SP1 can't connect to it. They got this error message:
ORA-12705: Cannot access NLS data files or invalid environment specified
There is no error if you use enUS Windows 7 SP1 machine. I tried many ways to solve this:
I checked language settings on server machine:
SELECT * FROM V$NLS_PARAMETERS;
SELECT USERENV ('language') FROM DUAL;
Both returns GERMAN_GERMANY.AL32UTF8.
I tried different ways to solve this issue by doing this:
Rename registry key NLS_LANG to NLS_LANGX on server machine. Did nothing.
Create NLS_LANG environment variable with value of GERMAN_GERMANY.AL32UTF8.
Control panel > Regional and language options > Format and set Russian there.
None of this works. What should I do?
had similar problem
adding following to VM arguments helped:
-Duser.language=en
-Duser.region=us
I had this problem with MacOS, when installing SQL developer several times. Adding VM option helped me (#kilonet answer). But here I am adding a new answer specifically for resolve MacOS problem.
Modify SQL Developer product configuration file (product.conf) in below path.
~/.sqldeveloper/<sqldeveloper version>/product.conf
Add add following two entries.
AddVMOption -Duser.language=en
AddVMOption -Duser.region=us
Thanks for question and the answer.
setting _JAVA_OPTIONS is an alternative global solution to all the Java applications are stating in a terminal.
export _JAVA_OPTIONS='-Duser.language=en -Duser.region=us'
For SQLDeveloper in Windows
sqldeveloper\sqldeveloper\bin\sqldeveloper.conf
Commment this line
AddVMOption -Duser.timezone="-06:00"
# AddVMOption -Duser.timezone="-06:00"

Just change the regional and language in your OS, make sure it matches with the oracle regional and language.
Open SQLDeveloper -> Preferences -> Database -> NLS

Here are the details:
I installed the oracle instant client 11.2.0.2.0 from the OTN download page on a windows 7 64 bit vm (vmware).
I am trying to to connect to a remote oracle database, and I can successfully connect with one program using TNS, but not with SQL*Plus and other applications.
Trying to connect with SQL*Plus, using schema#servicename, password, etc, gives the above error.
To connect via SQL Developer, normally I would use the basic connection info and not rely on tnsnames, but trying a normal connection gives me: io error: unknown host specified. SQL Developer can successfully connect and query database if i use the TNS protocol.
Trying from other programs gives me the same error I got with SQL*Plus. Same when trying with the service name from tnsnames.
This is obviously quite frustrating for it to work one way and not the other. I followed all the normal instructions for using the instant client, the directory with instantclient has been addded to the PATH, a TNS_ADMIN entry has also been created, with the directory to the tnsnames.ora file
Well, on a whim, I went to changing everything in my setup to match an windows 2003 server that i had setup with instant client before. The main changes were putting the instant client in a folder at the root of the drive (not program files/oracle/etc), but c:/oracle, i know ive seen other posts saying that oracle was particular about characters in the directory path, maybe spaces are a no-no too?
I also add a bunch more environmental variables, anythign that was on the other machine, ORACLE_HOME (to root of instance), SQL_PATH (same), and added the root of the directory to the PATH system variable, not just the folder with the instantclient files. Anyways, I'm happy its working, anyone one of these changes could have been it though-
You may use ProcessMonitor and look at what your sqlplus process is doing. In my case TNS_ADMIN was correctly defined but, by mistake, my tnsnames.ora and sqlnet.ora had a stupid ".txt" extension, added by default by notepad when I created those files. And because "Windows Explorer" has the "Hide extensions for known file types" option set by default, the naming error wasn't obvious at all.
I installed the 12.1 instant client. For me, the problem was solved by creating \network\admin\tnsnames.ora file. Here's the PowerShell I used:
$source = "C:\Users\USER1\Desktop\tnsnames.ora"
$target = "C:\oracle\product\12.1.0\client_1\network\admin"
mkdir $target
copy-item $source $target
