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

    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:h2:tcp://localhost/~/registryDB;create=true</url>
               <username>regadmin</username>
               <password>regadmin</password>
               <driverClassName>org.h2.Driver</driverClassName>
               <maxActive>80</maxActive>
               <maxWait>60000</maxWait>
               <minIdle>5</minIdle>
               <testOnBorrow>true</testOnBorrow>
               <validationQuery>SELECT 1</validationQuery>
               <validationInterval>30000</validationInterval>
			   <defaultAutoCommit>false</defaultAutoCommit>
           </configuration>
      </definition>
</datasource>

    The elements in the above configuration are described below:

    ElementDescription
    urlThe URL of the database. The default port for a DB2 instance is 50000.
    username and passwordThe name and password of the database user
    driverClassNameThe class name of the database driver
    maxActiveThe maximum number of active connections that canbeallocated atthesame 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.

    testOnBorrow  

    		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.
    defaultAutoCommit

    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 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.

    Info

    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.

...

  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.

    Code Block
    languagexml
    <dbConfig name="wso2registry">
	<dataSource>jdbc/MY_DATASOURCE_NAME</dataSource>
</dbConfig>

  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.

    Code Block
    languagexml
    <Configuration>
	<Property name="dataSource">jdbc/MY_DATASOURCE_NAME</Property>
</Configuration>
