∟Setting Up Java DB (Derby) in Network Server

This section describes how to set up and run Java DB in Network Server mode listening client connections over the network.

Java DB can be used in two modes:

Embedded Mode - The database will be started and executed as part of a Java application, sharing the same JVM as the application.
Network Server - The database will be started as a stand alone application and listening client connections over the network on a TCP/IP port.

I want to try the Network Server mode first. Here is what I did to setup Java DB and start it in Network Server mode. Open a command line window and run the following commands:

herong> cd lib
herong> mkdir javadb
herong> cd javadb

(on Windows)
herong> %DERBY_HOME%\bin\startnetworkserver

(on Linux or macOS)
herong> $DERBY_HOME/bin/startnetworkserver
... : Security manager installed using the Basic server security policy.
... : Apache Derby Network Server - 10.15.1.3 - (1853019) started and
   ready to accept connections on port 1527

Cool. My Java DB (Derby database server) is up and running in Network Server mode on host "localhost" and listening connections on port "1527".

Note that I created a new sub-directory in my own "lib" directory and started Java DB from there. This sub-directory will become the Derby database home directory. Any new databases created on Java DB server will be located in this sub-directory.
