SQL adapter connectionPolicy element

The connectionPolicy element of the adapter-descriptor file lets you configure settings for our adapter's SQL connection.

This page describes only the connectionPolicy element of the adapter-descriptor file. For information about other elements, see The JavaScript adapter-descriptor file.

Structure

The connectionPolicy element has two options for connection:

• The dataSourceDefinition subelement for development mode
• The dataSourceJNDIName subelement for production mode

Attributes

The connectionPolicy element has one attribute:

xsi:type

Mandatory.

The value of this attribute must be set to sql:SQLConnectionPolicy.

Subelements

The connectionPolicy element must contain one of the following two subelements.

dataSourceDefinition

Optional

Contains the parameters that are needed to connect to a data source. The adapter creates a connection for each request.

For example:

<connectionPolicy xsi:type="sql:SQLConnectionPolicy">
    <dataSourceDefinition>
        <driverClass>com.mysql.jdbc.Driver</driverClass>
        <url>jdbc:mysql://localhost:3306/mysqldbname</url>
        <user>user_name</user>
        <password>password</password>
    </dataSourceDefinition>
</connectionPolicy>

dataSourceJNDIName

Optional.

Connect to the data source by using the JNDI name of a data source that is provided by the application server. The adapter takes the connection from the server connection pool that is associated with the JNDI name.

Application servers provide a way to configure data sources. For more information, see Install MobileFirst Server to an application server. For example:

<connectionPolicy xsi:type="sql:SQLConnectionPolicy">
  <dataSourceJNDIName>my-adapter-ds</dataSourceJNDIName>
</connectionPolicy>
