Preparing the Derby Database

1. Download Apache Derby from http://apache.mesi.com.ar/db/derby/db-derby-10.8.2.2/ and save it to your computer.

2. Install Apache Derby on your computer using instructions given at http://db.apache.org/derby/manuals.

3. Go to the <derby-installation directory>/bin directory and run the Derby network server start script. Usually, it is named startNetworkServer.

Setup Configuration Files

1. Edit the default database configuration defined in the master-datasources.xml file located at $CARBON_HOME/repository/conf/datasources directory as below. Both the database configurations in registry.xml and user-mgt.xml refer this data source. 

Info
titleNote

Replace the following settings with your own custom values:

Code Block
languagehtml/xml
<datasource>
     <name>WSO2_CARBON_DB</name>
     <description>The datasource used for registry and user manager</description>
     <jndiConfig>
           <name>jdbc/WSO2CarbonDB</name>
     </jndiConfig>
     <definition type="RDBMS">
           <configuration>
               <url>jdbc:derby://localhost:1527/db;create=true</url>
               <userName>regadmin</userName>
               <password>regadmin</password>
               <driverClassName>org.apache.derby.jdbc.ClientDriver</driverClassName>
               <maxActive>80</maxActive>
               <maxWait>60000</maxWait>
               <minIdle>5</minIdle>
               <testOnBorrow>true</testOnBorrow>
               <validationQuery>SELECT 1</validationQuery>
               <validationInterval>30000</validationInterval>
           </configuration>
     </definition>
</datasource>
The Database Configuration Options
  • url - The URL of the database.
  • username - The name of the database user.
  • password - The password of the database user.
  • driverClassName - The class name of the database driver.
  • maxActive - The maximum number of active connections that can be allocated from this pool at the same time or negative for no limit.
  • maxWait - The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception, or <= 0 to wait indefinitely.
  • minIdle - The minimum number of active connections that can remain idle in the pool without extra ones being created or 0 to create none.
Info
titleNote

In contrast to the embedded Derby, in the remote registry, you will set the database driver name (the driverName element) to the value org.apache.derby.jdbc.ClientDriver and the database URL (the url element) to the database remote location.

Setup Drivers

Copy derby.jar, derbyclient.jar and derbynet.jar from $DERBY_HOME/lib in to $CARBON_HOME/repository/components/extensions directory (to the class path of the WSO2 ESB web application).

Create Database

Automatic Database Creation

1. The first time you start the server, run it with the -Dsetup option so that it will create the Derby database.

  • For Windows:
Code Block
wso2server.bat -Dsetup
  • For Linux:
Code Block
wso2server.sh -Dsetup

2. The WSO2 ESB is configured to run using a remote Apache Derby database.

Manual Database Creation

1. Run the ij tool located in the <derby-installation directory>/bin directory.

2. Create the database and connect to it using the following command inside the ij prompt:

Info
titleNote

Replace the database file path, user name, and password in the below command to suit your requirements.

Code Block
connect 'jdbc:derby://localhost:1527/db;user=regadmin;password=regadmin;create=true';

3. Exit from the ij tool by typing the exit command.

Code Block
exit;

4. Log in to the ij tool with the username and password you just used to create the database.

Code Block
connect 'jdbc:derby://localhost:1527/db' user 'regadmin' password 'regadmin';

5. Run the Derby scripts for both the registry and user manager (embedded) databases, provided with the WSO2 ESB, using the following command:

Code Block
run 'CARBON_HOME/dbscripts/derby.sql';

6. Restart the server. Now WSO2 ESB is running using a remote Apache Derby database.
