Creating a MySQL database for WSO2 Carbon 3.x.x products

WSO2 Carbon products have an inbuilt H2 database. Additionally the Carbon framework allows you to switch to the databases such as Oracle, MSSQL,MySQL, Derby, DB2.

You can easily switch between these databases by;
- creating a database schema within the relevant RDBMS
- point the configuration scripts to that db
- copy the drivers
- start the server with -Dsetup
I will describe these steps in a separate post.

This post is about how you can manually configure the database. I will be using MySql in my illustration. And I will be using WSO2 Identity Server 3.0 -alpha releases for this.


Creating MySQL database for WSO2 Carbon
-----------------------------------------------------------------
1. Download a wso2 identity server 3.0 alpha release

2. Navigate to the location where you have the mysql script. i.e. CARBON_HOME/dbscripts

3. Open a command prompt from that location and login to mysql from cmd prompt

mysql -u root -p

4. Create a database. Create user and grant access

create database regdb;
GRANT ALL ON regdb.* TO regadmin@localhost IDENTIFIED BY "regadmin";

6. Run the mysql.sql script. This will configure the database.

use regdb;
source mysql.sql

7. Copy the database driver to CARBON_HOME\repository\components\lib. I used mysql-connector-java-5.1.7-bin.jar, which is the official JDBC driver for MySQL. It can be downloaded from here.



8. Configure usermanager and registry scripts, which reside in CARBON_HOME/repository/conf

registry.xml

<currentDBConfig>mysql-db</currentDBConfig>
        <dbConfig name="mysql-db">
            <url>jdbc:mysql://localhost:3306/regdb</url>
            <userName>regadmin</userName>
            <password>regadmin</password>
            <driverName>com.mysql.jdbc.Driver</driverName>
            <maxActive>80</maxActive>
            <maxWait>6000</maxWait>
            <minIdle>5</minIdle>
       </dbConfig>

user-mgt.xml

<Database>
         <URL>jdbc:mysql://localhost:3306/regdb</URL>
         <UserName>regadmin</UserName>
         <Password>regadmin</Password>
         <Dialect>mysql</Dialect>
         <Driver>com.mysql.jdbc.Driver</Driver>
    </Database>
