When you use the Business Process profile in WSO2 EI, two separate databases are required for storing data specific to BPMN and BPEL. This is in addition to the default /wiki/spaces/ADMIN5xx/pages/22151545 default Carbon database. By default, the Business Process profile is shipped with embedded H2 databases for this purpose:

...

These databases are stored in the in the <EI_HOME>/wso2/brokerbusiness-process/repository/database directory.

Info

For instructions on changing the default Carbon database, see /wiki/spaces/ADMIN5xx/pages/22151545 Changing the Carbon Database in the WSO2 Product Administration Guide.

...

  1. Open the <EI_HOME>/wso2/business-process/conf/datasources/bps-datasources.xml file and locate the <datasource> configuration element.

  2. You simply have to update the url pointing to your database, the username and password required to access the database and the driver details as shown below.

  3. Optionally, you can update the configuration elements given below for your database connection.

    ElementDescription
    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.
    defaultAutoCommit

    Specifies whether each SQL statement should be automatically committed when it is completed. It is recommended to disable auto committingby setting this property to true.

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 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. 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.
