Overriding the data source configuration properties using policies

Policies are used to override property values so that you can control the behavior of message flows and message flow nodes at run time.

1. In the Application Development view, click New > Policy.
2. Select an existing policy project or click New to create a policy project.
3. Enter a name for your policy. The DataSource Policy Name List is in the IBM® App Connect for Manufacturing node property editor.
4. Click Finish. A policyxml file is created and is opened in the Policy editor.
5. In the Policy editor, select User Defined as the Policy Type from the list.
6. Select User Defined as the Policy Template from the list.
7. Add the appropriate Property Name values for your policy.
   The following table describes the mapping of the policy's user-defined Property Name with the data source configuration properties from the DataSource Config view.

   Table 1. Mapping of the Property Name and DataSource Config properties

   User Defined Property Name	DataSource Config UI
   CLIENT_KEEP_ALIVE	Client Keep-Alive
   CREDENTIAL_NAME
   DISCOVERY_ENDPOINT	Discovery Endpoint URL
   MESSAGE_ENCODING	Message Encoding
   MESSAGE_SECURITY_MODE	Message Security Mode
   PROTOCOL	Protocol
   QUEUED_PUBREQ_COUNT	Queued PubReq Count
   SECURITY_CLIENT_CERT	Client Certificate file
   SECURITY_CLIENT_PRIV_KEY	Client Private Key file
   SECURITY_POLICY	Security Policy
   SECURITY_SERVER_CERT	Server Certificate file
   SECURITY_USER	User Name
   SERVER_KEEP_ALIVE	Server Keep-Alive
   SERVER_URL_TYPE	Server URL Type
   UPDATE_INTERVAL	Update Interval

   Important: The QUEUED_PUBREQ_COUNT property specifies the number of the Publish Requests sent by a server. If you change the value of the Queued PubReq Count in the DataSource Config view, you must create the message flow again to use the updated values.

   • Click Add from the Policy Editor to add a new property name and value. The Add a new property window pop-up. You can add multiple data source properties to override.
   • Specify the data source property name and value that you want to override, and click OK. Refer to the mapping table, for the property name references.

   Note: For policies, you can no longer override the SECURITY_PASSWORD property, as the password is stored in the normal text that can lead to security issues. You can instead override CREDENTIAL_NAME property by using the value as given in the mqsicredentials command. After overriding, the password is searched against the value given in the CREDENTIAL_NAME property. For more information, see Configuring vault-enabled integration server.
8. Optional: You can Edit or Delete an existing data source property name and value from the Policy Editor.
9. Save your policy. Any errors are reported on the Problems tab.
