Change the boot Java runtime of the IDE
As a Java application, DataGrip includes JetBrains Runtime (based on OpenJDK 11), which is used by default. It is recommended to run DataGrip using JetBrains Runtime, which fixes various known OpenJDK and Oracle JDK bugs, and provides better performance and stability. However, in some cases you may be required to use another Java runtime or a specific version of JetBrains Runtime.
Switch the Java runtime used to run DataGrip
From the main menu, selector press Ctrl+Shift+A.
Find and select the Choose Boot Java Runtime for the IDE action.
Select the desired runtime and click OK.
If necessary, you can change the location where DataGrip will download the selected runtime.
Wait for DataGrip to restart with the new runtime.
When you open the Choose Boot Runtime for the IDE dialog for the first time, it may take a while to load the list of runtimes from the server. The list contains JetBrains Runtime builds hosted on BinTray.
To use a different Java runtime available on your computer, select Add Custom Runtime under Advanced. DataGrip lists all the JDKs and JREs that it was able to detect. Alternatively, click Add JDK to specify the location of the desired Java home directory.
To reset back to the default runtime that the IDE initially used, click Use Default Runtime.
The path to the selected runtime is stored in the datagrip.jdk or datagrip64.jdk file in the DataGrip configuration directory. If there are problems with the selected runtime, you can delete this file to revert to the default runtime.
You can also override the runtime used for DataGrip by adding the
DATAGRIP_JDK environment variable with the path to the desired JDK home directory.
