Tip
titleBefore you begin
You need to set up Oracle before following the steps to configure WSO2 IoTS with Oracle. For more information, see Setting up Oracle

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 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.

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.
Info
  • The default port for Oracle is 1521.
  • For more information on other parameters that can be defined in the < IoTS_HOME>/conf/datasources/master-datasources.xml file, see  Tomcat JDBC Connection Pool .

Excerpt

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 comes by default or set up a separate database for identity or storage related data, the instructions are the same. In summary:

  1. Add a new datasource configuration to the following files for each of the separate databases that you need to create.

    For the identity databaseAdd it to the <PRODUCT_HOME>/repository/conf/datasources/<check the correct path and add file name (something like master-datasources.xml)>
    For the storage databaseAdd 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 databaseAdd it to the <PRODUCT_HOME>/repository/conf/<check the correct path and add file name (something like api-manager.xml)
  2. Create the database tables using the following scripts:

    For the identity databaseUse <PRODUCT_HOME>/dbscripts/identity/<check the correct path and add file name (something like mysql.sql)>
    For the storage databaseUse <PRODUCT_HOME>/dbscripts/storage/<check the correct path and add file name (something like /mysql/resoucre.sql)>
    For the product-specific databaseUse <PRODUCT_HOME>/dbscripts/<check the correct path and add file name (something like /apimgt/mysql.sql)> 
  3. 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
      languagexml
      <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.
