Modify Data Store Connections

You can modify data store connections.

You must be logged in as an administrator or as a user with the group privilegeCan Manage Connections to maintain data store connection definitions.

To modify a data store connection definition:

1. Make sure you are logged into Composer as an administrator or as a user with the group privilegeCan Manage Connections.

2. Select Connections on the top-level navigation banner or the UI menu () or select the Connections box on the Home page. The Connections page appears.

   The Connections page lists the data store connections you have defined and identifies how many data source configurations each connection uses.

   

3. Select the data store connection definition you want to modify. Its details appear on the next page on the Connection Details tab. You can search the list to locate the data store connection definition. See Search for a Definition in a List.

   

4. To change the name of the connection, select next to the name at the top of the page. This makes the name editable.

   

   Change the name and select .

5. Use the boxes on the Connection Details tab to alter the URL and other connection details and, if applicable, the authentication credentials (User Name and Password boxes) required to connect to the data store. Any connection requirements for a specific data store are described in the connector documentation for that data store. See the Composer Data Connector Reference.

   You can insert variables for connection parameters, if any custom attributes have been defined. See Insert Variables for Connection Parameters. In addition, if user attributes have been set up for connection parameters, they can be selected using the up and down arrows in a connection parameter box. See Use User Attributes for Connection Parameters.

6. If the Do As User box is available and you want to enable user delegation, optionally specify the custom user attribute set up for user delegation. See Apply User Delegation to a Connection.

7. This is an optional step.

   Each data source configuration specifies refresh settings for the data from the data store. If a data store connection requires special credentials in order for Composer to refresh the data source data, select the button under Scheduler Overrides and select an override setting to use. The override settings you can specify mirror the regular data store connection settings (except for the connection definition name) and vary based on the type of data store connector used for the connection. See Composer Data Connector Reference.

   More than one override setting can be specified. Simply select the button again and select a different setting and provide its input value. Repeat this process until all override settings required by the data store have been specified.

8. Select to validate the connection. If the connection is valid, it is saved.

9. To see the data source configuration definitions that use this connection definition, select the Data Sources tab.

10. Select at the top of the page to return to the Connections page that lists the connection definitions.
