Use the sysinfo utility to display information about
your Java environment and
Derby (including version
information).
To use sysinfo, do one of the following:
- If you are relatively new to the Java programming language, follow the 
instructions in "Setting up your environment" in
Getting Started with Derby to set the 
DERBY_HOME 
and JAVA_HOME environment variables and to add
DERBY_HOME/bin
to your path. Then use the following command:
sysinfo 
- If you are a regular Java user but are new to
Derby, set the 
DERBY_HOME
environment variable, then use a java command to invoke the 
derbyrun.jar file:
(UNIX) java [options] -jar $DERBY_HOME/lib/derbyrun.jar sysinfo
 (Windows) java [options] -jar %DERBY_HOME%\lib\derbyrun.jar sysinfo
 
- If you are familiar with both the Java programming language and
Derby, you have already set 
DERBY_HOME. 
Set your classpath to include the 
Derby
jar files. Then use a java command to invoke the 
sysinfo class directly.
