I have Oracle SQL Developer v4.1.3. Currently I am able to connect with my database. But after connecting to database when I try to open SQL Worksheet, nothing happen. I am not able to open my SQL Worksheet.
I try to open 'Open SQL Worksheet' or Alt+F10, but nothing will be happen.
When I try to connect to database, I successfully connect to database but I am getting below error on log pane.
I download the new version of Oracle SQL Developer v4.1.5. But I am facing same issue.
I already see one post (SQL Worksheet is not displaying in SQL Developer) related to this question. But it will not help me.
I am using Oracle SQL Developer as direct run not installed.
I have windows 10 and jdk1.8.0_60 (64bit) installed.
Please help me to fix this.
I'm also faced this and finally found the issue. This has happend because of antivirus(kaspeskey).
So, disabled the antivirus, it works fine.

So I downloaded Oracle 19c DBMS. Then I downloaded Sql Developer. When I try to add a new connection, I get the message
How do I get past this. I have seen some other threads on this but none of the solutions that I understand seem to fix it. I need to keep the connection type as local. Is there somewhere I can go and just adjust this path?
EDIT
I used just a basic connection and the name database name in the service name box and it worked. The initial setup instructions I had were dated and not set up for 19c. One of the comments in the answer below suggested this.
For 20.4.1 and bequeath connection you must have a 21c instant client as we're using a 21c jdbc driver.
If you're not on Linux, that means you'll need version 20.4.0 so you can use a 19c Instant Client.
Windows 21c Clients should be available later this Summer.
Edit/Update: Version 21.2.1 now supports 19c and 21c Clients. 21c Instant Clients are rolling out across supported platforms. Currently avail for Linux, soon to include Windows and OS X.
In my case, the DB connection changed from Network Alias to Connect Identifier post a company pushed update, simple fix after hours /days of trouble shooting.

Ran into this error with Oracle SQL Developer and the fix for us was to in Oracle SQL Developer:
Tools -> Preferences
In the tree view on the left Expand Database and select Advanced
In Use Oracle Client click Configure...
Set the path to your Oracle home (should looks something like C:\Path\To\Oracle\19.n)
Check the Use Oracle Client box
In the Tnsnames Directory set it to the folder containing the tnsnames.ora file (should looks something like C:\Path\To\Oracle\19.n\network\admin)
Click OK
Relaunch Oracle SQL Developer
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 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.
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.

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 try connect to my oracle db with oracle SQL developer and received that message:

if i try connect with sql plus, all well.
command : select userenv('LANGUAGE') from dual;
result:
Connected to:

in SQL DEVELOPER:

check\uncheck "Skip NLS Settings", nothing changed.
what the issue is?
I've seen this problem before in an installation with Oracle 10g on AIX. The problem was that NLS files weren't accessible due to wrong file protection.
The problem is most likely not with SQL Developer but on the server side. When you log in, the server will always try to set regional settings that match the one on your client. That's when the error occurs because the required files aren't accessible.
If you haven't already I think it might be worth asking this question in the OTN SQL Developer Forum
I suspect you installed the Western European edition instead of the Universal. If that's not the case, post the file list from the nls/data directory.
