The following sections describe how to replace the default H2 database with MS SQL:

Setting up the database and users

Follow the steps below to set up the Microsoft SQL database and users.

Enable TCP/IP

  1. In the start menu, click Programs and launch Microsoft SQL Server 2005.
  2. Click Configuration Tools, and then click SQL Server Configuration Manager.
  3. Enable TCP/IP and disable Named Pipes from protocols of your Microsoft SQL server.
  4. Double click TCP/IP to open the TCP/IP properties window, and set Listen All to Yes on the Protocol tab.
  5. On the IP Address tab, disable TCP Dynamic Ports by leaving it blank and give a valid TCP port, so that Microsoft SQL server will listen on that port.

    The best practice is to use port 1433, because you can use it in order processing services.

  6. Similarly, enable TCP/IP from SQL Native Client Configuration and disable Named Pipes. Also check whether the port is set correctly to 1433.
  7. Restart Microsoft SQL Server.
Create the database and user
  1. Open Microsoft SQL Management Studio to create a database and user.
  2. Click New Database from the Database menu, and specify all the options to create a new database.
  3. Click New Login from the Logins menu, and specify all the necessary options.
Grant permissions

Assign newly created users the required grants/permissions to log in, create tables, and insert, index, select, update, and delete data in tables in the newly created database, as the minimum set of SQL server permissions. 

Setting up the JDBC driver

Download and copy the sqljdbc4 Microsoft SQL JDBC driver file to the WSO2 product's <PRODUCT_HOME>/repository/components/lib/ directory. Use as the <driverClassName> in your datasource configuration in <PRODUCT_HOME>/repository/conf/datasources/master-datasources.xml file.

Setting up datasource configurations

A datasource is used to establish the connection to a database. By default, WSO2_CARBON_DB datasource is used to connect to the default  H2 database, which stores registry and user management data. After setting up the Microsoft SQL database to replace the default H2 database, either change the default configurations of the WSO2_CARBON_DB datasource, or configure a new datasource to point it to the new database as explained below.

Changing the default WSO2_CARBON_DB datasource

Follow the steps below to change the type of the default WSO2_CARBON_DB datasource.

  1. Edit the default datasource configuration in the <PRODUCT_HOME>/repository/conf/datasources/m aster-datasources.xml file as shown below.

        <description>The datasource used for registry and user manager</description>
        <definition type="RDBMS">
                  <validationQuery>SELECT 1</validationQuery>

    The elements in the above configuration are described below:


    Give the URL to connect to the Microsoft SQL database. Shown below is the most simple form of the database connection URL. It includes the URL and two parameters:


    Change <IP> to the IP of the server. The best practice is to use port 1433 because you can use it in order processing services.

    Set SendStringParametersAsUnicode to ‘false’ in order to overcome a limitation in the Microsoft SQL client driver. Without this parameter, the database driver will erroneously convert VARCHAR data into NVARCHAR and lower the database's performance.

    username and passwordThe name and password of the database user
    driverClassNameThe class name of the database driver
    maxActiveThe maximum number of active connections that can be allocated  at the same time from this pool. Enter any negative value to denote an unlimited number of active connections.
    maxWaitThe 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. You can enter zero or a negative value to wait indefinitely.
    minIdleThe minimum number of active connections that can remain idle in the pool without extra ones being created, or enter zero to create none.


    The indication of whether objects will be validated before being borrowed from the pool. If the object fails to validate, it will be dropped from the pool, and another attempt will be made to borrow another.
    validationQueryThe SQL query that will be used to validate connections from this pool before returning them to the caller.
    validationIntervalThe indication to avoid excess validation, and only run validation at the most, at this frequency (time in milliseconds). If a connection is due for validation, but has been validated previously within this interval, it will not be validated again.

    This property is not applicable to the Carbon database in WSO2 products because auto committing is usually handled at the code level, i.e., the default auto commit configuration specified for the RDBMS driver will be effective instead of this property element. Typically, auto committing is enabled for an RDBMS drivers by default.

    When auto committing is enabled, each SQL statement will be committed to the database as an individual transaction, as opposed to committing multiple statements as a single transaction.

    For more information on other parameters that can be defined in the <PRODUCT_HOME>/repository/conf/datasources/master-datasources.xml file, see Tomcat JDBC Connection Pool.

Configuring new  datasources to manage registry or user management data

Follow the steps below to configure new datasources to point to the new  databases you create to manage registry and/or user management data separately.

  1. Add a new datasource with similar configurations as the WSO2_CARBON_DB datasource above to the <PRODUCT_HOME>/repository/conf/datasources/ master-datasources.xml file. Change its elements with your custom values. For instructions, see Setting up datasource configurations.
  2. If you are setting up a separate database to store registry-related data, update the following configurations in the <PRODUCT_HOME>/repository/conf/ registry.xml file.

    <dbConfig name="wso2registry">
  3. If you are setting up a separate database to store user management data, update the following configurations in the <PRODUCT_HOME>/repository/conf/ user-mgt.xml file.

    	<Property name="dataSource">jdbc/MY_DATASOURCE_NAME</Property>

Creating the database tables

To create the database tables, connect to the database that you created earlier and run the following scripts.

  1. To create tables in the registry and user manager database (WSO2CARBON_DB), use the below script:

  2. Restart the server.

    You can create database tables automatically when starting the product for the first time by using the -Dsetup parameter as follows:

    • For Windows: <PRODUCT_HOME>/bin/wso2server.bat -Dsetup

    • For Linux: <PRODUCT_HOME>/bin/ -Dsetup

Changing the BPS database

The topics above show how to change the WSO2_CARBON_DB, which is used to store registry and user manager information. If you changed the BPS database that comes by default, the instructions are the same. In summary:

  1. Add the datasource to the master-datasources.xml file. Change its elements with your custom values.

    Create the database tables using the following scripts:

    For the BPS database

    Use <PRODUCT_HOME>/dbscripts/bps/mssql.sql
