sysinfo

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 Java DB 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.
