org.apache.derby.tools
Class sysinfo

java.lang.Object
  extended byorg.apache.derby.tools.sysinfo

public class sysinfo
extends java.lang.Object

This class displays system information to system out. To run from the command-line, enter the following:

java org.apache.derby.tools.sysinfo

Also available on this class are methods which allow you to determine the version of the code for the system without actually booting a database. Please note that this is the Derby version of the .jar files, not of your databases.

The numbering scheme for released Derby products is m1.m2.m3 where m1 is the major release version, m2 is the minor release version, and m3 is the maintenance level. Versions of the product with the same major and minor version numbers are considered feature compatible.

Valid major and minor versions are always greater than zero. Valid maintenance versions are greater than or equal to zero.
