As a parameter to the JVM command line

You can set system-wide properties as parameters to the JVM command line when starting up the application or framework in which Derby is embedded.

IBM Application Developer Kits
With the IBM?? SDK, you set JVM system properties by using a -D flag on the Java command line. For example:
```
java -Dderby.system.home=C:\home\Derby\ 
    -Dderby.storage.pageSize=8192 JDBCTest
```

For other JVMs, see the JVM-specific documentation on setting system properties.
