## org.apache.derby.tools
Class sysinfo

    java.lang.Object
      org.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.

Field Summary
`static java.lang.String` | `CLIENT` The genus name for the client code.
`static java.lang.String` | `DBMS` The genus name for the Apache Derby code.
`static java.lang.String` | `NET` The genus name for the network server code.
`static java.lang.String` | `TOOLS` The genus name for the tools code.

Method Summary
`static java.lang.String` | `getBuildNumber()` gets the build number for the Apache Derby embedded library
`static java.lang.String` | `getBuildNumber(java.lang.String genus)` gets the build number for the specified library
`static void` | `getInfo(java.io.PrintWriter out)`

`static int` | `getMinorVersion()` gets the minor version of the Apache Derby embedded code.
`static int` | `getMinorVersion(java.lang.String genus)` gets the minor version of the specified code library.
`static java.lang.String` | `getProductName()` gets the product name for the Apache Derby embedded library
`static java.lang.String` | `getProductName(java.lang.String genus)` gets the external name for the specified code library.
`static java.lang.String` | `getVersionString()` Return the version information string for the specified library including alpha or beta indicators.
`static java.lang.String` | `getVersionString(java.lang.String genus)` Return the version information string for the Apache Derby embedded library including alpha or beta indicators.
