I've installed Oracle 11g r2 to my machine and when I opened Oracle SQL Developer it says: java 1.6.0_02 is not supported and telling me to install new java version.
Then I've installed JDK 1.6.0_27 and set the path in environment variables and run Oracle SQL Developer again, but the same error occurred.
How can I change the settings for Oracle SQL Developer to recognize 1.6.0_27 as my SDK?
sqldeveloper.conf under sqldeveloper/bin in the SQLDeveloper base directory has an entry for the java home being used.
(So, on Windows, if you have unzipped SQLDeveloper to C:\sqldev then sqldeveloper.conf is under C:\sqldev\sqldeveloper\bin)
Something like:
SetJavaHome C:\Program Files\Java\jdk1.6.0_20
Quit SQLDeveloper, remove this entry and relaunch SQLDeveloper. You should be prompted for the location of Java.
In windows 10, I needed to go to following folder and change following product.conf file and set SetJavaHome directive.
%APPDATA%\sqldeveloper\<product-version>\product.conf
in my machine:
C:\Users\ati_o\AppData\Roaming\sqldeveloper\17.4.0\product.conf
with following line.
SetJavaHome C:\Tools\oraclejdk8
Thanks to comment from @thatjeffsmith, in MacOS or Linux/Unix, go to:
$HOME/.sqldeveloper/<product-version>/product.conf
to set same SetJavaHome directive.
Go to sqldeveloper\sqldeveloper\bin and edit sqldeveloper.conf file.
There you'll see
SetJavaHome C:\Program Files\Java\jdk1.6.0_21
Change it to correct jdk path
Yes, Oracle just made a dumb installation package to makes us waste our time...good job guys!!!
The thing is, there should be a wizard/installer to configure the java path, this is because the jdk that comes pre-configured just doesn't work. Personally, I had to edit to the sqldeveloper.conf
under sqldeveloper\bin just has Nivas said and change the pre-configured path "SetJavaHome ../../jdk" to "SetJavaHome C:\Program Files\Java\jdk1.8.0_73" - for earlier versions of sqldeveloper it's a requirement to have Java8 and be sure that if you install SQLDeveloper x64 version that the java version that you set in your path is also x64.
With SQL Developer 19.1 (2018) I tried to install it with Java 11 but it failed, so for luck I still have an old java 8 version jdk8u202-b08. If that happens you need to remove this folder
C:\Users\<username>\AppData\Roaming\sqldeveloper
And then run the exe again
C:\..\sqldeveloper-19.1\sqldeveloper.exe
This workaround helped many people (including me) during the last 12 months, so you must try it if you still have the problem:
- Go to sqldeveloper\jdk\jre\bin folder and locate "msvcr100.dll"
- Copy this dll to C:\Windows\System32 folder
Obs: you will need to provide administrator authorization to finish the file copy, so you must be logged on as a true windows administrator.
After copying the file, just try to start the sqldeveloper again. No reboot needed.
Hope this helps you too!
One solution is to install the latest Oracle SQL Developer. Link @ SQL Developer Downloads . This installation will install and use the latest Java version 1.8.x.
The sqldeveloper.conf file resides at a newer location at ...\sqldeveloper\sqldeveloper\bin .
In order to change the version of SDK linked to your SQL developer, uninstall the other versions of SDK and install the required version. Once you install the required version, try running SQL developer it will automatically prompt you to attach the path. ANd you can provide the new path.
None of the sqldeveloper.conf had an entry in my case, and i downloaded another zip installation, which gave me same error for same JDK versoin, without me configuring anything, S
