The following sections describe how to replace the default H2 databases with Oracle:
Setting up the database and users
If you get a

WSO2_CARBON_DB datasource is used to connect to the default H2 database, which stores registry and user management data. After setting up the Oracle 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.
Edit the default datasource configuration in the <
aster-datasources.xmlfile as shown below.
Code Block language 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:oracle:thin:@SERVER_NAME:PORT/DB_NAME</url> <username>regadmin</username> <password>regadmin</password> <driverClassName>oracle.jdbc.driver.OracleDriver</driverClassName> <maxActive>80</maxActive> <maxWait>60000</maxWait> <minIdle>5</minIdle> <testOnBorrow>true</testOnBorrow> <validationQuery>SELECT 1 FROM DUAL</validationQuery> <validationInterval>30000</validationInterval> </configuration> </definition> </datasource>
The elements in the above configuration are described below:
Element Description url The URL of the database. The default port for a DB2 instance is 50000. username and password The name and password of the database user driverClassName The class name of the database driver maxActive The 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. 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. You can enter zero or a negative value to wait indefinitely. minIdle The 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. validationQuery The SQL query that will be used to validate connections from this pool before returning them to the caller. validationInterval The 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. Info
The default port for Oracle is 1521.
For more information on other parameters that can be defined in the <
master-datasources.xmlfile, see Tomcat JDBC Connection Pool.
- Add a new datasource with similar configurations as the
WSO2_CARBON_DBdatasource above to the <
master-datasources.xmlfile. Change its elements with your custom values. For instructions, see Setting up datasource configurations.
If you are setting up a separate database to store registry-related data, update the following configurations in the <
Code Block language xml
<dbConfig name="wso2registry"> <dataSource>jdbc/MY_DATASOURCE_NAME</dataSource> </dbConfig>
If you are setting up a separate database to store user management data, update the following configurations in the <
Code Block language xml
<Configuration> <Property name="dataSource">jdbc/MY_DATASOURCE_NAME</Property> </Configuration>
Creating the database tables
To create the database tables, connect to the database that you created earlier and run the following scripts in SQL*Plus:
To create tables in the registry and user manager database (
WSO2CARBON_DB), use the below script:
Code Block language powershell
Restart the server.
You can create database tables automatically when starting the product for the first time by using the
-Dsetupparameter as follows:
Note to writers: Add this content at the end of the page if any of the additional databases is relevant to your product.
Changing the identity/storage/product-specific databases
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 product-specific database that come by default or set up a separate database for identity or storage related data, the instructions are the same. In summary:
Add a new datasource configuration to the following files for each of the separate databases that you need to create.
|For the identity database||Add it to the |
|For the storage database||Add it to the <|
|For the product-specific database||Add it to the <|
Create the database tables using the following scripts:
|For the identity database||Use |
|For the storage database||Use |
|For the product-specific database||Use |
Update the following configurations, with the defined datasource name of the corresponding database configuration you added to the
If you are setting up a separate database to store identity related data, update the following configurations in the <
<JDBCPersistenceManager> <DataSource> <!-- Include a data source name (jndiConfigName) from the set of datasources defined in master-datasources.xml --> <Name>jdbc/WSO2CarbonDB</Name> </DataSource> </JDBCPersistenceManager>
all WSO2 products are configured to use the embedded H2 database. To configure your product with MSSQL, see Changing to Oracle.
