# 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.
