As an alternative to start DbVisualizer via the menu items and icons created by the installer, you can also start DbVisualizer from a shell (terminal) on all operating systems using the following scripts:

# DbVisualizer GUI on Windows:
DBVIS-HOME\dbvisgui.bat
 
# DbVisualizer GUI on Linux/UNIX:
DBVIS-HOME/dbvisgui.sh
 
# DbVisualizer GUI on macOS:
DbVisualizer.app/Contents/java/app/dbvisgui.sh

The scripts supports a number of command line arguments. These are also listed in the Help->About menu choice, under the Command Line tab, in DbVisualizer.

Usage: dbvisgui [-connection <name>] [-userid <userid>] [-password <password>]
                [-encoding <encoding>]
                [-prefsdir <directory>]
                [-windowtitle <title>]
                [-help] [-version]
                [<filename>]
General Options:
 -connection <name>    Database connection name (created with the GUI)
 -userid <userid>      Userid to connect as
 -password <password>  Password for userid
 -encoding <encoding>  Encoding for the SQL script file
 -prefsdir <directory> Use an alternate user preferences directory
 -windowtitle <title>  Additional window title
 -help                 Display this help
 -version              Show version info
 <filename>            SQL script file to load into editor

JAVA_EXEC

Please note that these scripts use the first Java version that is found in the PATH. The result may be that a non supported Java version is used.

You can specify a specific version by setting the environment variable JAVA_EXEC to point at an executable Java (note: set this using the operating system's mechanism, not by editing the dbvisgui script).

Example: Windows

(adjust paths to match your environment)
