Using the Derby tools and startup utilities

There are several tools and utilities that you might want to use as you begin to work with Derby.

The tools that are included with Derby are dblook, ij, and sysinfo. To run these tools see:

Derby includes a set of scripts that you can use to start the Derby tools. The scripts are located in the DERBY_HOME/bin directory. When you run these scripts, your CLASSPATH environment variable is set if you have not already set it, and remains set as long as you are running the tool.

Most of the examples in this guide that show how to use the Derby scripts to launch the Derby tools assume that you are using the embedded mode of the Derby database engine. Use the instructions below to run the scripts with the Network Server.

Running the scripts with the Network Server

To run the scripts with the Network Server, use the following commands:
  • For the sysinfo tool, issue the command
    NetworkServerControl sysinfo
  • For the ij tool, issue the command
    set DERBY_OPTS=-Dij.protocol=jdbc:derby://localhost/
    and then start ij by issuing the command ij.
  • For the dblook tool, call the script and specify the -d option and the full connection URL to the Network Server database. For example:
    dblook -d 'jdbc:derby://localhost/myDB;user=usr'

Additional Derby utilities

In addition, there are Derby utilities that are system procedures that you can call by using the ij tool. For example, there are system procedures that you can use to import and export external files. Instructions on how to use these system procedures are included in the Derby Server and Administration Guide and the Derby Reference Manual.
