Running sysinfo

The Derby??sysinfo tool displays information about your Java environment and your version of Derby.

The sysinfo utility prints system information to a console.

Choose the method that you can use to run the sysinfo script:

Method When to Use Command
Run sysinfo as a standalone command. Use this method if you are relatively new to the Java programming language and new to Derby. You must set your environment variables before you can run the sysinfo utility using this method.

To run the sysinfo script from the command line us:

sysinfo

The sysinfo script sets the appropriate environment variables, including the CLASSPATH, and runs the sysinfo utility.

Run sysinfo using the jar file that is located in the directory where sysinfo resides. Use this method if you are new to Derby, but are familiar with the Java programming language. You must set the DERBY_HOME environment variable before you can run the sysinfo utility using this method.

On UNIX, the command is:

java [options] -jar $DERBY_HOME/lib/derbyrun.jar sysinfo

On Windows, the command is:

java [options] -jar %DERBY_HOME%\lib\derbyrun.jar sysinfo
Run sysinfo using the java command. Use this method if you are familiar with both the Java programming language and Derby, and you have already set the java.exe file in your command execution PATH. You must set your CLASSPATH. Use the steps specified in Manually setting the CLASSPATH environment variable. Then specify the class name in the java command. For example:
java org.apache.derby.tools.sysinfo
See "sysinfo" in the Derby Tools and Utilities Guide for more information about using the sysinfo utility.
