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 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.
```
java org.apache.derby.tools.sysinfo
