The Java supplied with RDBExpert is used by default. When upgrading from older versions of RDBExpert (2025.05 and below), Java will be downloaded automatically.

To use third-party Java, you need to specify it in RDBExpert/config/launcher.conf. You must use an absolute path to the executable file, for example:

Example for Windows:

app.java.path=C:\ProgramFiles\openjdk-21\bin\java.exe

Example for Linux:

app.java.path=/usr/lib/jvm/openjdk-21/bin/java

You can run the application from the console as java -jar rdbexpert.jar command from the directory where rdbexpert.jar is located, You can also launch the Launcher by running the command ./RDBExpert64. When starting the Launcher, you can specify JVM arguments, for example:

./RDBExpert64 -Djna.debug_load=true

Also JVM arguments can be specified in RDBExpert/config/launcher.conf:

# ---------------------
# - JVM CONFIGURATION -
# ---------------------
-Djna.debug_load=true # as example
