Info
To test products on Oracle RAC, rename `oracle_rac.sql` to `oracle.sql` before running `-Dsetup`.

Setting up the database and users

Follow the steps below to set up an Oracle RAC database.

Set environment variables <ORACLE_HOME>, PATH,and ORACLE_SID with the corresponding values /oracle/app/oracle/product/11.2.0/dbhome_1, $PATH:<ORACLE_HOME>/bin, and orcl1 as follows:
Connect to Oracle using SQL*Plus as SYSDBA.

Create a database user and grant privileges to the user as shown below:

Code Block

language	powershell

Create user <USER_NAME> identified by password account unlock;
grant connect to <USER_NAME>;
grant create session, create table, create sequence, create trigger to <USER_NAME>;
alter user <USER_NAME> quota <SPACE_QUOTA_SIZE_IN_MEGABYTES> on '<TABLE_SPACE_NAME>';
commit;

Exit from the SQL*Plus session by executing the quit command.

`Setting up the JDBC driver`

Copy the Oracle JDBC libraries (for example, the <ORACLE_HOME>/jdbc/lib/ojdbc14.jar file) to the <PRODUCT_HOME>/repository/components/lib/ directory.

Info
Remove the old database driver from the `<PRODUCT_HOME>/repository/components/dropins/` directory when you upgrade the database driver.

`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 Oracle RAC 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.

`Anchor Changing the default database Changing the default database Changing the default WSO2_CARBON_DB datasource`

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

Edit the default datasource configuration in the <PRODUCT_HOME>/repository/conf/datasources/m aster-datasources.xml file 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:@(DESCRIPTION=(LOAD_BALANCE=on)
   			       (ADDRESS=(PROTOCOL=TCP)(HOST=racnode1) (PORT=1521))
   			       (ADDRESS=(PROTOCOL=TCP)(HOST=racnode2) (PORT=1521))
   			       (CONNECT_DATA=(SERVICE_NAME=rac)))</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.
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.
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
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
Configuring new datasources to manage registry or user management data
`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.

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.
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
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 <PRODUCT_HOME>/repository/conf/ user-mgt.xml file.
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
SQL> @$<PRODUCT_HOME>/dbscripts/oracle.sql

Restart the server.

Info

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/wso2server.sh -Dsetup

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 `<PRODUCT_HOME>/repository/conf/datasources/<check the correct path and add file name (something like master-datasources.xml)>`
For the storage database	Add it to the <`PRODUCT_HOME>/repository/conf/datasources/<check the correct path and add file name (something like master-datasources.xml)`
For the product-specific database	Add it to the <`PRODUCT_HOME>/repository/conf/<check the correct path and add file name (something like api-manager.xml)`

Create the database tables using the following scripts:

For the identity database	Use `<PRODUCT_HOME>/dbscripts/identity/<check the correct path and add file name (something like mysql.sql)>`
For the storage database	Use `<PRODUCT_HOME>/dbscripts/storage/<check the correct path and add file name (something like /mysql/resoucre.sql)>`
For the product-specific database	Use `<PRODUCT_HOME>/dbscripts/<check the correct path and add file name (something like /apimgt/mysql.sql)>`

Update the following configurations, with the defined datasource name of the corresponding database configuration you added to the <PRODUCT_HOME>/repository/conf/datasources/master-datasources.xml file.

If you are setting up a separate database to store identity related data, update the following configurations in the <PRODUCT_HOME>/repository/conf/identity.xml file.

Code Block

language	xml

<JDBCPersistenceManager>
	<DataSource>
		<!-- Include a data source name (jndiConfigName) from the set of datasources defined in master-datasources.xml -->
		<Name>jdbc/WSO2CarbonDB</Name>
	</DataSource>
</JDBCPersistenceManager>

Note to writers: For step 3, add content on the XML files which include references on any of the additional databases and require edits that are relevant to your product similar to the given example.
