Configure Connections to the Data Integration Hub Repositories

Configure Connections to the
Data Integration Hub
 Repositories

Configure connections to the
Data Integration Hub
 repositories. After you configure the connections,
Data Integration Hub
 creates the connections in the PowerCenter repository.
Data Integration Hub
 uses the connections details to create workflows for publications and for subscriptions, and to create data sources and data targets in PowerCenter .
To configure the connections, you must be logged in to the
Data Integration Hub
 Operation Console with the administrator user account.
  1. In the Navigator, click
    Hub Management
    Connections
    .
    The
    Connections
     page appears, showing the DIH__REPO and DIH__STAGING connections.
  2. Click the
    Edit
     icon next to the DIH__REPO connection.
    The
    Edit Connection
     page appears, showing the DIH__REPO connection details. DIH__REPO is the connection to the
    Data Integration Hub
     metadata repository that you defined during installation.
  3. Configure the
    Database Name
     if applicable and the
    Data Access
     properties of the connection. For more information, see the

     tests the connection. The process might take a few moments.
  6. When the message "Connection successful" shows, click
    OK
     in the
    Test Connection
     dialog box.
    The first time that you test connections in
    Data Integration Hub
    , the test might fail with an error. Wait one minute and then test the connection.
    If the test fails after you wait a few seconds, delete the folder
    DIH__SYSTEM_WORKFLOWS
     in PowerCenter, and then test the connection.

    • <port>
       is the port on which NameNode listens for remote procedure calls (RPC).
    • <path>
